Administer systemic corticosteroids and inhaled bronchodilators to control the exacerbation and improve airflow Which statement best describes the concept of pain? a. Pain is an uncomfortable experience present only in the patient with an intact nervous system. b. Pain is an unpleasant experience accompanied by crying and tachycardia. c. Pain is activation of the sympathetic nervous system from an injury. d. Pain is whatever the patient experiencing it says it is, occurring when that patient says it does. ANS: D Pain is described as an unpleasant sensory and emotional experience associated with actual or potential t issue damage or described in terms of such damage. This definition emphasizes the subjective and multidimensional nature of pain. More specifically, the subjective characteristic implies that pain is whatever the person experiencing it says it is and that it exists whenever he or she says it does. What are the neural processes of encoding and processing noxious stimuli associated with pain called? a. Perception b. 10 Nociception c. Transduction d. Transmission ANS: B Nociception represents the neural processes of encoding and processing noxious stimuli necessary, but not sufficient, for pain. Transduction refers to mechanical (eg, surgical incision), thermal (eg, burn), or chemical (eg, toxic substance) stimuli that damage tissues. As a result of transduction, an action potential is produced and is transmitted by nociceptive nerve fibers in the spinal cord that reach higher centers of the brain. This is called transmission, and it represents the second process of nociception. Pain sensation transmitted by the nervous system (NS) pathway reaches the thalamus, and the pain sensation transmitted by the parasympathetic nervous system (PS) pathway reaches brainstem, hypothalamus, and thalamus. These parts of the central nervous system (CNS) contribute to the initial perception of pain. C fibers are small-diameter, unmyelinated fibers that transmit what type of pain? a. Aching b. Sharp c. Prickling d. Concentrated ANS: A C fibers are implicated in the transmission of pain described as dull, diffuse, prolonged, and delayed. Alpha fibers conduct the rapid acute pain sensation described as prickling, sharp, and fast. These fibers are activated by mechanical and thermal stimuli and are carried by the neospinothalamic tract. Which assessment findings might indicate respiratory depression after opioid administration? a. Flushed, diaphoretic skin b. Shallow respirations with a rate of 24 breaths/min 11 c. Tense, rigid posture d. Snoring Answer: D. Snoring is a warning sign. It can be a sign of respiratory depression associated with airway obstruction by the tongue, leading to hypoxemia and possibly to cardiorespiratory arrest. A patient snoring after the administration of an opioid requires the critical care nurse to observe closely. The patient is admitted to the critical care unit with hemodynamic instability and an allergy to morphine. The nurse anticipates that the practitioner will order which medication for severe pain? a. Hydromorphone b. Codeine c. Fentanyl d. Methadone Answer: C. Fentanyl is a synthetic opioid preferred for critically ill patients with hemodynamic instability or morphine allergy. Hydromorphone is a semisynthetic opioid that has an onset of action and a duration similar to those of morphine. It is more potent than morphine. Hydromorphone produces an inactive metabolite (ie, hydromorphone-3-glucuronide), making it the opioid of choice for use in patients with end-stage renal disease. Codeine has limited use in the management of severe pain. It is rarely used in critical care units. It provides analgesia for mild to moderate pain. It is usually compounded with a nonopioid. Methadone is a synthetic opioid with morphine-like properties but less sedation. It is longer acting than morphine and has a long half-life. This makes it difficult to titrate in the critical care patient Which combinations of drugs has been found to be effective in managing the pain associated with musculoskeletal and soft tissue inflammation? a. Nonsteroidal antiinflammatory drugs (NSAIDs) and opioids b. NSAIDs and antidepressants c. 12 Opioid agonists and opioid antagonists d. Adjuvants and partial agonists ANS: A The use of nonsteroidal anti-inflammatory drugs (NSAIDs) in combination with opioids is indicated in patients with acute musculoskeletal and soft tissue inflammation. A patient underwent a thoracotomy 12 hours ago and has continuous epidural analgesia with morphine. In addition to respiratory depression, the patient should be monitored for which complications? a. Urinary retention, undue somnolence, itching, nausea, and vomiting b. Urinary incontinence, photophobia, headache, and skin rash c. Apprehension, anxiety, restlessness, sadness, anger, and myoclonus d. Gastric bleeding, nasal discharge, cerebrospinal fluid leak, and calf pain ANS: A Epidural analgesia is commonly used in critical care units after major abdominal surgery, nephrectomy, thoracotomy, and major orthopedic procedures. Monitor for adverse reactions, including respiratory depression, urinary retention, undue somnolence, itching, seizures, nausea, and vomiting. A patient underwent a thoracotomy 12 hours ago and has continuous epidural analgesia with morphine. In addition to closely monitoring the patient for side effects and complications, which intervention might enhance the patient's pain control? a. Maintain her flat in bed during the infusion. b. Position her on her right side to encourage flow of the medication across the dura. c. Limit visitors and remove any distractions such as television and music. d. 13 Consider administration of adjunct medication such as a nonsteroidal antiinflammatory agent. ANS: D Positioning will not affect medication administration, distractions such as visitors and soothing music can often enhance the effects of pharmacologic pain control, adjuvant medications can help decrease anxiety, and nonopioid analgesics can provide greater pain relief at the peripheral and central levels. Instruct and guide patient through nonpharmacologic measures (eg, relaxation therapy, guided imagery, and biofeedback) to enhance pharmacologic effectiveness. The epidural space is filled with fatty tissue and is external to the dura mater. The fatty tissue interferes with uptake, and the dura acts as a barrier to diffusion, making diffusion rate difficult to predict. Which statement accurately describes the duration of acute pain? a. Acute pain is associated with the injury to the joints and lasts about 9 months. b. Acute pain is associated with the healing process and should not exceed 6 months. c. Acute pain is persistent pain of more than 6 months after the healing process. d. Acute pain is associated with damage to the nervous system and is of infinite duration. ANS: B Acute pain has a short duration, and it usually corresponds to the healing process (30 days) but should not exceed 6 months. It implies tissue damage that is usually from an identifiable cause. If undertreated, acute pain may bring a prolonged stress response and lead to permanent damage to the patient's nervous system. In such instances, acute pain can become chronic. A patient complains of pain at his incision site. The nurse is aware that four processes are involved in nociception. In what order do the processes occur? a. Transmission, perception, modulation, and transduction b. Perception, modulation, transduction, and transmission c. Modulation, transduction, transmission, and perception 14 d. Transduction, transmission, perception, and modulation ANS: D Four processes are involved in nociception: transduction, transmission, perception, and modulation. Why use a specific pain intensity scale in the critical care unit? a. It eliminates the subjective component from the assessment. b. It focuses on the objective component of the assessment. c. It provides consistency of assessment and management. d. It provides a way to interpret physiologic indicators. ANS: C Many critical care units use a specific pain intensity scale because a single tool provides consistency of assessment, management, and documentation. A pain intensity scale is useful in the critical care environment. Asking the patient to grade his or her pain on a scale of 0 to 10 is a consistent method and aids the nurse in objectifying the subjective nature of the patient's pain. However, the patient's tool preference should be considered. The patient is sedated and breathing with the use of mechanical ventilation. The patient is unable to communicate any aspects of his pain to the nurse. What tool should the nurse use to assess the patient's pain? a. FLACC b. Wong-Baker FACES c. BIS d. BPS ANS: D 15 The BPS and the CPOT are supported by experts in critical care and are suggested for use in medical, postoperative, and nonbrain trauma critically ill adults unable to self-report in the clinical guidelines of the Society of Critical Care Medicine (SCCM). FLACC is a pediatric pain assessment tool. The Wong-Baker FACES tool requires the patient to associate a level of pain to a facial representation. BIS is as an objective measure of sedation levels during neuromuscular blockade in the critical care unit. Which of the following patients is MOST likely to be experiencing a life-threatening opioid side effect? a. Patient with respiratory rate of 10 breaths/min who is breathing deeply b. Patient with a respiratory rate of 8 breaths/min who is snoring c. Patient with blood pressure of 150/75 mm Hg and heart rate of 102 beats/min d. Patient with a temperature of 100.5° F who is asleep but easily roused ANS: B Although no universal definition of respiratory depression exists, it is usually described in terms of decreased respiratory rate (fewer than 8 or 10 breaths/min), decreased SpO2 levels, or elevated ETCO2 levels. A change in the patient's level of consciousness or snoring is a warning sign. It can be a sign of respiratory depression associated with airway obstruction by the tongue, leading to hypoxemia and possibly to cardiorespiratory arrest. A patient snoring after the administration of an opioid requires the critical care nurse to observe closely. The nurse is caring for a patient with liver dysfunction. What is the maximum dose of acetaminophen the patient should receive in 24 hours? a. 1 grams b. 2 grams c. 4 grams d. 500 milligrams ANS: B 16 Special care must be taken for patients with liver dysfunction, malnutrition, or a history of excess alcohol consumption, and their acetaminophen total dose should not exceed 2 g/day. A patient has been taking Demerol 50 mg tablets three times a day for the past 5 years for chronic back pain; however, the patient complains that the medication is not providing the same level of pain relief as it once did. Based on this statement the nurse suspects that the patient has developed what problem? a. Addiction b. Tolerance c. Physical dependence d. Physical withdrawal ANS: B The patient has developed a tolerance to the medication. Tolerance is defined as a diminution of opioid effects over time. Addiction is defined by a pattern of compulsive drug use that is characterized by an incessant longing for an opioid and the need to use it for effects other than pain relief. Physical dependence to opioids may develop if the medication is given over a long period. Physical dependence is manifested by withdrawal symptoms when the opioid is abruptly stopped The nurse is caring for a patient with a patient-controlled analgesia (PCA). The patient's spouse asks about the advantages of using this type of pain management therapy. What should the nurse say to the spouse? a. "The method allows the patient to act preemptively by administering a bolus of medication when pain begins." b. "This method allows the patient to choose between an opioid and a nonopioid medication to control pain." c. "This method decreases the risk of respiratory depression and other side effects." d. 17 "This method allows for the rise and fall of the blood level of the opioid." ANS: A The patient can self-administer a bolus of medication the moment the pain begins, acting preemptively. Allowing the patient to self-administer opioid doses does not diminish the role of the critical care nurse in pain management. The nurse advises about necessary changes to the prescription and continues to monitor the effects of the medication and doses. The patient is closely monitored during the first 2 hours of therapy and after every change in the prescription. If the patient's pain does not respond within the f irst 2 hours of therapy, a total reassessment of the pain state is essential. If the patient is pressing the button to bolus medication more often than the prescription, the dose may be insufficient to maintain pain control. Naloxone must be readily available to reverse adverse opiate respiratory effects. Relaxation, distraction, guided imagery, and music therapy are all examples what type of pain management? a. Physical techniques b. Cognitive-behavioral techniques c. Nonopioid analgesia d. Equianalgesia ANS: B Using the cortical interpretation of pain as the foundation, several interventions can reduce the patient's pain report. These modalities include cognitive techniques such as relaxation, distraction, guided imagery, and music therapy The patient has received ketamine for its analgesic effects. The patient suddenly states, "I feel like I am f loating and can see everything you are doing. I am not in control." What is this response called? a. Hallucination state b. Guided imagery c. Dissociative state 18 d. Adverse event ANS: C Before administering ketamine, the dissociative state should be explained to the patient. Dissociative state refers to the feelings of separateness from the environment, loss of control, hallucinations, and vivid dreams. The use of benzodiazepines (eg, midazolam) can reduce the incidence of this unpleasant effect. A nurse is administering naloxone to a patient experiencing respiratory depression. Which of the following interventions must be observed when using naloxone? (Select all that apply.) a. Naloxone is normally given rapidly via IV. b. Naloxone is discontinued as soon as a patient is responsive to physical stimulation and able to take deep breaths. c. Naloxone has a shorter duration than most opioids, so the nurse may need to repeat naloxone as early as 30 minutes after the first dose. d. The patient's pain control is easily established after receiving naloxone. e. Naloxone is not recommended after prolonged analgesia because it can induce withdrawal and may cause nausea and dysrhythmias. ANS: B, C, D Naloxone is normally given intravenously very slowly (0.5 mL over 2 minutes) while the patient is carefully monitored for reversal of the respiratory signs. Naloxone administration can be discontinued as soon as the patient is responsive to physical stimulation and able to take deep breaths. However, the medication should be kept nearby. Because the duration of naloxone is shorter than most opioids, another dose of naloxone may be needed as early as 30 minutes after the first dose. The benefits of reversing respiratory depression with naloxone must be carefully weighed against the risk of a sudden onset of pain and the difficulty achieving pain relief. To prevent this from occurring, it is important to provide a nonopioid medication for pain relief. Moreover, the use of naloxone is not recommended after prolonged analgesia because it can induce withdrawal and may cause nausea and cardiovascular complications (eg, dysrhythmias). Which statements are true regarding pain assessment and management? (Select all that apply.) 19 a. The single most important assessment tool available to the nurse is the patient's self-report. b. The only way to assess pain in patients unable to verbalize because of mechanical ventilation is through observation of behavioral indicators. c. The concept of equianalgesia uses morphine as a basis for dosage comparison for other medications. d. Transcutaneous electrical nerve stimulation and application of heat or cold therapy stimulate the nonpain sensory fibers. e. ANS: A, C, D Meperidine, a synthetic form of morphine, is much stronger and is given at lower doses at less frequent intervals. Appropriate pain assessment is the foundation of effective pain treatment. Because pain is recognized as a subjective experience, the patient's self-report is considered the most valid measure for pain and should be obtained as often as possible. Unfortunately, in critical care, many factors, such as the administration of sedative agents, the use of mechanical ventilation, and altered levels of consciousness, may impact communication with patients. These obstacles make pain assessment more complex. Meperidine (Demerol) is a less potent opioid with agonist effects similar to those of morphine. It is considered the weakest of the opioids, and it must be administered in large doses to be equivalent in action to morphine. Because the duration of action is short, dosing is frequent. Equianalgesic means approximately the same pain relief. Dosages in the equianalgesic chart for moderate to severe pain are not necessarily starting doses. The doses suggest a ratio for comparing the analgesia of one medication with another. To achieve ventilator synchrony in a mechanically ventilated patient with acute respiratory distress syndrome (ARDS), which level of sedation might be most effective? a. Light b. Moderate c. Conscious d. 20 Deep ANS: D Deep sedation is used when the patient must be unresponsive to deliver necessary care safely. A patient has been taking benzodiazepines and suddenly develops respiratory depression and hypotension. After careful assessment, the nurse determines that the patient is experiencing benzodiazepine overdose. What is the nurse's next action? a. Decrease benzodiazepines to half the prescribed dose. b. Increase IV fluids to 500 cc/h for 2 hours. c. Administer flumazenil (Romazicon). d. Discontinue benzodiazepine and start propofol. ANS: C The major unwanted side effects associated with benzodiazepines are dose-related respiratory depression and hypotension. If needed, flumazenil (Romazicon) is the antidote used to reverse benzodiazepine overdose in symptomatic patients. A patient is admitted unit with acute respiratory distress syndrome (ARDS). The patient has been intubated and is mechanically ventilated. The patient is becoming increasingly agitated, and the high pressure alarm on the ventilator has been frequently triggered. What action should be the nurse take f irst? a. Administer midazolam 5 mg by intravenous push immediately. b. Assess the patient to see if a physiologic reason exists for his agitation. c. Obtain an arterial blood gas level to ensure the patient is not hypoxemic. d. Apply soft wrist restraints to keep him from pulling out the endotracheal tube. ANS: B 21 The first step in determining the need for sedation is to assess the patient quickly for any physiologic causes that can be quickly reversed. In this case, endotracheal suctioning may solve the high-pressure alarm problem. A patient is admitted with acute respiratory distress syndrome (ARDS). The patient has been intubated and is mechanically ventilated. The patient is becoming increasingly agitated, and the high-pressure alarm on the ventilator has been frequently triggered. The patient continues to be very agitated, and the nurse can find nothing physiologic to account for the high-pressure alarm. What action should the nurse take next? a. Administer midazolam 5 mg by intravenous push immediately. b. Eliminate noise and other stimuli in the room and speak softly and reassuringly to the patient. c. Obtain an arterial blood gas to ensure the patient is not becoming more hypoxemic. d. Call the respiratory care practitioner to replace the malfunctioning ventilator. ANS: B Optimizing the environment, speaking calmly, explaining things to the patient, and providing distractions are all nonpharmacologic means to decrease anxiety. A patient is admitted with acute respiratory distress syndrome (ARDS). The patient has been intubated and is mechanically ventilated. The patient is becoming increasingly agitated, and the high-pressure alarm on the ventilator has been frequently triggered. Despite the nurse's actions, the patient continues to be agitated, triggering the high-pressure alarm on the ventilator. Which medication would be appropriate to sedate the patient this time? a. Midazolam 2 to 5 mg intravenous push (IVP) every 5 to 15 minutes until the patient is no longer triggering the alarm b. Haloperidol 5 mg IVP stat c. Propofol 5 mcg/kg/min by IV infusion d. 22 Fentanyl 25 mcg IVP over a 15-minute period ANS: A Midazolam is the recommended drug for use in alleviating acute agitation. Propofol can be used for short- and intermediate-term sedation. Haloperidol is indicated for dementia. Fentanyl is a narcotic and is not appropriate for use as a sedative. A patient is admitted with acute respiratory distress syndrome (ARDS). The patient has been intubated and is mechanically ventilated. The patient had become very agitated and required some sedation. After the patient's agitation is controlled, which medications would be most appropriate for long-term sedation? a. Morphine 2 mg/h continuous IV drip b. Haloperidol 15 mcg/kg/min continuous IV infusion c. Propofol 5 mcg/kg/min by IV infusion d. Lorazepam 0.01 to 0.1 mg/kg/h by IV infusion ANS: D Propofol may be used for ongoing sedation for short- and intermediate-term sedation (1-3 days) and should be coupled with a short-acting opioid analgesic. Morphine is an opioid analgesic and is not sedation. Lorazepam infusion (0.01-0.1 mg/kg/h) is recommended for long-term sedation. When administering propofol over an extended period, what laboratory value should the nurse routinely monitor? a. Serum triglyceride level b. Sodium and potassium levels c. Platelet count d. Acid-base balance ANS: A 23 Prolonged use of propofol may cause an elevated triglyceride level because of its high lipid content. What is a major side effect of benzodiazepines? a. Hypertension b. Respiratory depression c. Renal failure d. Phlebitis ANS: B The major side effects of benzodiazepines include hypotension and respiratory depression. These side effects are dose related. What is the major advantage of using propofol as opposed to another sedative for short-term sedation? a. Fewer side effects b. Slower to cross the blood-brain barrier c. Shorter half-life and rapid elimination rate d. Better amnesiac properties ANS: C Propofol is an effective short-term anesthetic agent, useful for rapid "wake-up" of patients for assessment; if continuous infusion is used for many days, emergence from sedation can take hours or days; sedative effect depends on the dose administered, depth of sedation, and length of time sedated. Which of the following medications is used for sedation in patients experiencing withdrawal syndrome? a. Dexmedetomidine 24 b. Hydromorphone c. Diazepam d. Clonidine ANS: D Clonidine (often prescribed as a Catapres patch) is a central a-agonist and is recommended for sedation during withdrawal syndrome. A patient was admitted 5 days ago and has just been weaned from mechanical ventilation. The patient suddenly becomes confused, seeing nonexistent animals in the room and pulling at the bedding. The nurse suspects the patient may be experiencing what issue? a. Delirium b. Hypoxemia c. Hypocalcemia d. Sedation withdrawal ANS: A Delirium is represented by a global impairment of cognitive processes, usually of sudden onset, coupled with disorientation, impaired short-term memory, altered sensory perceptions (hallucinations), abnormal thought processes, and inappropriate behavior. There is no evidence provided that would indicate the patient is hypoxemic, hypocalcemic, or going through sedation withdrawal. A patient was admitted 5 days ago and has just been weaned from mechanical ventilation. The patient suddenly becomes confused, seeing nonexistent animals in the room and pulling at the bedding. What is the medication of choice for treating this patient? a. Diazepam b. 25 Haloperidol c. Lorazepam d. Propofol ANS: B Haloperidol is the drug of choice when treating delirium. Lorazepam has been associated with an increased incidence of delirium. Propofol is indicated for sedation use. Diazepam is not an appropriate choice for this patient. A patient was admitted 5 days ago and has just been weaned from mechanical ventilation. The patient suddenly becomes confused, seeing nonexistent animals in the room and pulling at the bedding. What parameter should be monitored while the patient is haloperidol? a. Sedation level b. QTc-interval c. Oxygen saturation level d. Brain waves ANS: B Electrocardiogram (ECG) monitoring is recommended because haloperidol use can produce dose dependent QTc-interval prolongation, with an increased incidence of ventricular dysrhythmias. BIS monitoring is indicated for deep sedation use. What is the most common contributing factor to the development of delirium in critically ill patients? a. Sensory overload b. Hypoxemia c. Electrolyte disturbances 26 d. Sleep deprivation ANS: D Delirium is frequently associated with critical illness. Provision of adequate sleep and early mobilization are recommended to reduce the incidence of delirium. Which medication has a greater advantage for treatment of alcohol withdrawal syndrome (AWS) because of its longer half-life and high lipid solubility? a. Lorazepam b. Midazolam c. Propofol d. Diazepam ANS: D Management of alcohol withdrawal involves close monitoring of AWS-related agitation and administration of IV benzodiazepines, generally diazepam (Valium) or lorazepam (Ativan). Diazepam has the advantage of a longer half-life and high lipid solubility. Lipid-soluble medications quickly cross the blood-brain barrier and enter the central nervous system to rapidly produce a sedative effect. Midazolam is the recommended drug for use in alleviating acute agitation but is known to cause seizures with AWS because of rapid withdrawal. Propofol is indicated for sedation use. What are the risk factors for delirium? a. Hypertension, alcohol abuse, and benzodiazepine administration b. Coma, hypoxemia, and trauma c. Dementia, hypertension, and pneumonia d. Coma, alcohol abuse, hyperglycemia ANS: A 27 Risk factors for delirium risk include dementia, hypertension, alcohol abuse, high severity of illness, coma, and benzodiazepine administration. What are the two scales that are recommended for assessment of agitation and sedation in adult critically ill patients? a. Ramsay Scale and Riker Sedation-Agitation Scale (SAS) b. Ramsay Scale and Motor Activity Assessment Scale (MAAS) c. Riker Sedation-Agitation Scale (SAS) and the Richmond Agitation-Sedation Scale (RASS) d. Richmond Agitation-Sedation Scale (RASS) and Motor Activity Assessment Scale (MAAS) ANS: C The two scales that are recommended for assessment of agitation and sedation in adult critically ill patients are the SAS and the RASS. Which intervention is an effective nursing strategy to decrease the incidence of delirium? a. Restriction of visitors b. Early nutritional support c. Clustering of nursing care activities d. Bedrest ANS: C As lack of sleep is a major contributor to the development of delirium, interventions to promote sleep should help decrease the incidence of delirium. Some critical care units have initiated sleep protocols to increase the opportunity for patients to sleep at night, dimming lights at night, ensuring there are periods of time when tubes are not manipulated, and clustering nursing care interventions to provide some uninterrupted rest periods. Early ambulation is also appropriate. 28 What are the causes of delirium in critically ill patients? (Select all that apply.) a. Hyperglycemia b. Meningitis c. Cardiomegaly d. Pulmonary embolism e. Alcohol withdrawal syndrome f. Hyperthyroidism B, E, F The causes of delirium in critically ill patients include metabolic causes (acid-base disturbance, electrolyte imbalance, hypoglycemia), intracranial causes (epidural or subdural hematoma, intracranial hemorrhage, meningitis, encephalitis, cerebral abscess, tumor), endocrine causes (hyperthyroidism or hypothyroidism, Addison disease, hyperparathyroidism, Cushing syndrome), organ failure (liver encephalopathy, kidney encephalopathy, septic shock), respiratory causes (hypoxemia, hypercarbia), and medication-related causes (alcohol withdrawal syndrome, benzodiazepines, heavy metal poisoning). Which complications can result from prolonged deep sedation? (Select all that apply.) a. Pressure ulcers b. Thromboembolism c. Diarrhea d. Nosocomial pneumonia e. 29 Delayed weaning from mechanical ventilation f. Hypertension ANS: A, B, D, E Oversedation can result in a multitude of complications. Prolonged deep sedation is associated with significant complications of immobility, including pressure ulcers, thromboembolism, gastric ileus, nosocomial pneumonia, and delayed weaning from mechanical ventilation. Which of the following statements about comfort care is accurate? a. Withholding and withdrawing life-sustaining treatment are distinctly different in the eyes of the legal community. b. Each procedure should be evaluated for its effect on the patient's comfort before being implemented. c. Only the patient can determine what constitutes comfort care for him or her. d. Withdrawing life-sustaining treatments is considered euthanasia in most states. ANS: B The goal of comfort care is to provide only treatments that do not cause pain or other discomfort to the patient What is a powerful influence when the decision-making process is dealing with recovery or a peaceful death? a. Hope b. Religion c. Culture d. Ethics ANS: A 30 Hope is a powerful influence on decision making, and a shift from hope for recovery to hope for a peaceful death should be guided by clinicians with exemplary communication skills. Ethics, religion, and culture can influence the decision process regarding care and end-of-life decisions. The patient's condition has deteriorated to the point where she can no longer make decisions about her own care. Which nursing interventions would be most appropriate? a. Obtain a verbal do-not-resuscitate (DNR) order from the practitioner. b. Continue caring for the patient as originally ordered because she obviously wanted this. c. Consult the hospital attorney for recommendations on how to proceed. d. Discuss with the family what the patient's wishes would be if she could make those decisions herself. ANS: D If the patient is not able to make end-of-life decisions for herself, her family members should be approached to discuss the next steps because they may have insight into what her wishes would be. What are the two basic ethical principles underlying the provision of health care? a. Beneficence and nonmaleficence b. Veracity and beneficence c. Fidelity and nonmaleficence d. Veracity and fidelity ANS: A The two basic ethical principles underlying the provision of health care are beneficence and nonmaleficence. 31 A patient was admitted several weeks ago with an acute myocardial infarction and subsequently underwent coronary artery bypass grafting surgery. Since a cardiac arrest 5 days ago, the patient has been unresponsive. An electroencephalogram shows no meaningful brain activity. The patient does not have an advance directive. Which statement would be the best way to approach the family regarding his ongoing care? a. "I will refer this case to the hospital ethics committee, and they will contact you when they have a decision." b. "What do you want to do about the patient's care at this point?" c. "Dr. Smith believes that there is no hope at this point and recommends do-not-resuscitate status." d. "What would the patient want if he knew he were in this situation?" ANS: D Approaching the family and asking what they know about the patient's wishes and preferences is the best way to begin this discussion. Emotional support for the patient and the family is important as they discuss advance care planning in the critical care setting. A patient was admitted several weeks ago with an acute myocardial infarction and subsequently underwent coronary artery bypass grafting surgery. Since a cardiac arrest 5 days ago, the patient has been unresponsive. An electroencephalogram shows no meaningful brain activity. After a family conference, the practitioner orders a do-not-resuscitate (DNR) order, and palliative care is begun. How does this affect the patient's treatment? a. The patient will continue to receive the same aggressive treatment short of resuscitation if he has another cardiac arrest. b. All treatment will be stopped, and the patient will be allowed to die. c. All attempts will be made to keep the patient comfortable without prolonging his life. d. The patient will be immediately transferred to hospice. ANS: C 32 When palliative care is begun, the primary goal is to keep the patient comfortable by continuing assessments and managing symptoms that might cause pain, anxiety, or distress. A patient was admitted several weeks ago with an acute myocardial infarction and subsequently underwent coronary artery bypass grafting surgery. Since a cardiac arrest 5 days ago, the patient has been unresponsive. An electroencephalogram shows no meaningful brain activity. The patient is placed on a morphine drip to alleviate suspected operative pain and assist in sedation. The patient continues to grimace and fight the ventilator. What nursing intervention would be appropriate? a. Increase the morphine dosage until no signs of pain or discomfort are present. b. Increase the morphine drip, but if the patient's respiratory rate drops below 10 breaths/min, return to the original dosage. c. Gradually decrease the morphine and switch to Versed to avoid respiratory depression. d. Ask the family to leave the room because their presence is causing undue stress to the patient. ANS: A Even though opiates can cause respiratory depression, the goal in palliative care is to alleviate pain and suffering. A bolus dose of morphine (2-10 mg IV) and a continuous morphine infusion at 50% of the bolus dose per hour is recommended. Because many critical care patients are not conscious, assessment of pain and other symptoms becomes more difficult. Gélinas and colleagues recommended using signs of body movements, neuromuscular signs, facial expressions, or responses to physical examination for pain assessment in patients with altered consciousness. A patient was admitted several weeks ago with an acute myocardial infarction and subsequently underwent coronary artery bypass grafting surgery. Since a cardiac arrest 5 days ago, the patient has been unresponsive. An electroencephalogram shows no meaningful brain activity. The decision is made to remove the patient from the ventilator. Which of the following statements is most accurate? a. The cardiac monitor should be left on so everyone will know when the patient has died. b. Opioids, sedatives, and neuromuscular blocking agents should be discontinued just before removing the ventilator. 33 c. The family and health care team should decide the best method for removing the ventilator terminal wean versus immediate extubation. d. If terminal weaning is selected, the family should be sent to the waiting room until the ventilator has actually been removed. ANS: C The choice of terminal wean as opposed to extubation is based on considerations of access for suctioning, appearance of the patient for the family, how long the patient will survive off the ventilator, and whether the patient has the ability to communicate with loved ones at the bedside. A patient was admitted to the critical care unit after having a cerebrovascular accident (CVA) and myocardial infarction (MI). The patient has poor activity tolerance, falls in and out of consciousness, and has poor verbal skills. The patient has been resuscitated four times in the past 6 hours. The patient does not have advance directives. Family members are at the bedside. Who should the practitioner approach to discuss decisions of care and possible do-not-resuscitate (DNR) status? a. Patient b. Family c. Hospital legal system d. Hospital ethics committee ANS: A Patients' capacity for decision making is limited by illness severity; they are too sick or are hampered by the therapies or medications used to treat them. When decision making is required, the patient is the f irst person to be approached. Which statement regarding organ donation is accurate? a. Organ donation is a choice only the patient can make for him- or herself. b. Hospitals must have written protocols for the identification of potential organ donors. 34 c. Organ donation must be requested by the nurse caring for the dying patient. d. Individual institutional policies govern how organ donation requests are made. ANS: B The Social Security Act Section 1138 requires that hospitals have written protocols for the identification of potential organ donors. The Joint Commission has a standard on organ donation. The nurse must notify the organ procurement official to approach the family with a donation request. Hospice care is an option that should be considered, especially in end-stage illness. Hospice care can help families with which issue(s)? a. Organ and tissue donations b. Symptom management and family support c. Procurement of advance directives and living wills d. Legal and voluntary euthanasia ANS: B Health professionals can assist patients and families by providing information about the hospice benefit, particularly regarding the aggressive symptom management and family support. Organ donations must follow Social Security Act Section 1138 regarding written protocols for identification of potential organ donors and notification of organ recovery agencies. Advance directives can be taken care of at the hospital or legal firm. Euthanasia generally not offered through hospice. Disagreement and distress among practitioners, nurse practitioners, and critical care nurses can lead to what issue? a. Moral indignation b. Ethical resentment c. 35 Moral distress d. Interprofessional anguish ANS: C Nurses and doctors frequently disagree about the futility of interventions. Sometimes nurses consider withdrawal before practitioners and patients do, and they then believe the care they are giving is unnecessary and possibly harmful. This issue is a serious one for critical care nurses because moral distress can lead to burnout. In caring for a patient receiving palliative care, antiemetics are used in the treatment of what problem? a. Dyspnea b. Nausea and vomiting c. Anxiety d. Edema ANS: B Nausea and vomiting are common and should be treated with antiemetics. Dyspnea is best managed with close evaluation of the patient and the use of opioids, sedatives, and nonpharmacologic interventions (oxygen, positioning, and increased ambient air flow). Benzodiazepines, especially midazolam with its rapid onset and short half-life, are frequently used to treat anxiety. Haloperidol are traditionally been used to managed which symptom? a. Anxiety b. Dyspnea c. Delirium d. Pain ANS: C 36 Delirium is commonly observed in critically ill patients and in those approaching death. Haloperidol and benzodiazepines (such as midazolam, lorazepam) have traditionally been used to manage delirium but have side effects that can be problematic. More recently, atypical antipsychotics have proven equally effective without troubling side effects of other drug classes. Dyspnea is best managed with close evaluation of the patient and the use of opioids, sedatives, and nonpharmacologic interventions (oxygen, positioning, and increased ambient air flow). Benzodiazepines, especially midazolam with its rapid onset and short half-life, are frequently used to treat anxiety. Morphine is the most common drug used for pain management. A patient tells the nurse to call his family and tell them they need to come so they can say their goodbyes. The patient is sure he will not be here tomorrow because his grandparent is waiting for him. What is the patient exhibiting? a. Anxiety b. Delirium c. Metabolic derangement d. Near-death awareness ANS: D The same behaviors may be seen in conscious critical care patients near death. Having an awareness of the phenomenon enables more careful assessment of behaviors that may be interpreted as delirium, acid-base imbalance, or other metabolic derangements. These behaviors include communicating with someone who is not alive, preparing for travel, describing a place the patient can see, or even knowing when death will occur. Recommendations for creating a supportive atmosphere during end-of-life discussions include which intervention? a. Telling the family when and where the procedure will occur b. Beginning the conversation by inquiring about the emotional state of the family c. Ending the conversation by inquiring about the emotional state of the family 37 d. Recommendations that the family not be present when the procedure occurs ANS: B Recommendations for creating a supportive atmosphere during withdrawal discussions include taking a moment at the beginning of the conversation to inquire about the family's emotional state. During the family meeting in which a decision to withdraw life support is made, a time to initiate withdrawal is usually established. What is the most common complaint heard from families of dying patients? a. Poor nursing care b. Inadequate communication c. Lack of consistent plan of care d. Confusion among health care team members ANS: B Communication seems to be the most common source of complaints in families across studies and should be at the center of efforts to improve end-of-life care. Families have commonly complained about infrequent physician communication, unmet communication needs in the shift from aggressive to end of-life care, and lacking or inadequate communication. Which of the following are considerations when making the decision to allow family at the bedside during resuscitation efforts? (Select all that apply.) a. The patient's wishes b. Experience of the staff c. The family's need to participate in all aspects of the patient's care d. State regulatory issues 38 e. Seeing the resuscitation may confirm the impact of decisions made or delayed ANS: A, B, C, E The decision to allow family members at the bedside during resuscitative efforts should be made by the family and caregivers and be based on needs and experiences. The family may become more aware of what is involved in decisions if they ar
