HESI MEDICALSURGICAL LPN -EXAM PACK BEST FOR 2023 EXAM LATEST VERSION Question 1 The nurse is providing care for a patient who is unhappy with the health care provider’s care. The patient signs the Against Medical Advice (AMA) form and leaves the hospital against medical advice. What should the nurse include in the documentation of this event in the patient’s medical record or on the AMA form? 1. Documentation that the patient wasinformed that he or she cannot come back to the hospital 2. Documentation that the patient wasinformed that he or she wasleaving against medical advice 3. Documentation that the risks of leaving against medical advice were explained to the patient 4. Documentation of any discharge instructions given to the patient 5. Documentation indicating an incident report has been completed Correct Answer: 2,3,4 Rationale 1: Itshould be clearly documented that the patient was advised and understands that he or she can come back. Rationale 2: It should be clearly documented in the patient’srecord and on the AMA form that the patient was advised that he or she was leaving against medical advice. Rationale 3: It should be clearly documented that the patient understandsthe risks of leaving against medical advice. Rationale 4: The AMA form includes the name of the person accompanying the patient and any discharge instructions given. Rationale 5: Facility policy may require that an incident report be completed, but it must not be referenced in the chart. The patient’srecord is a legal document, so the nurse should never document that he or she filed an incident report. Question 2 A nurse documents this statement in a patient’s medical record: “2/25/–, 2235. At 2015 patient awoke suddenly and complained ofshortness of air. Pulse oximetry reading was 82% on room air and audible wheezes could be heard.” This documentation meets which documentation guidelines? 1. Documentation istimely 2. Documentation is concise 3. Documentation is objective 4. Documentation includes date and time of entry 5. Documentation is complete and accurate Correct Answer: 2,3,4,5 Rationale 1: The nurse should document as soon as possible after an observation is made or care is provided. The entry was made in the patient’s medical record at least 2 hours after the patient complaint and should be labeled late entry. Rationale 2: This entry describes the situation fully but is concise. Rationale 3: The nurse describesfactual events that can be seen, heard,smelled, or touched. It isimportant to be objective and avoid vague statements that are subjective. Rationale 4: Both the date and the time of the entry are documented. Rationale 5: The nurse should document only facts: what he or she can see, hear, and do. Question 3 A nurse documents the following in a patient’s medical record: “2/1/ , 1500. Patient appears weak and faint. Patient’s skin is moist and cool, vomited bright red blood with clots. Health care provider notified and order received to give 2 u of packed red blood cells if stat Hgb is < 8.0. Pain medication will be given.” This documentation meets which documentation principle? 1. Document objectively. 2. Do not document proceduresin advance. 3. Use approved abbreviations. 4. Document changesin patient condition. Correct Answer: 4 Rationale 1: Documentation should be objective and avoid vague statements that are subjective. Only factual occurrences that can be seen, heard, smelled, or touched should be described. The use of the word “appears” issubjective and could be manipulated latershould the treatment or judgment be challenged. Rationale 2: The nurse has documented that pain medication will be given. Thisis documenting in advance. Rationale 3: The Joint Commission has designated the inappropriateness of “u” as an abbreviation. “U” should bewritten out as “unit(s).” If unsure whether the abbreviation is correct, the nurse should spell out the word; “<” can be misinterpreted, so it should be spelled out as “less than.” Rationale 4: In general, employers as well asstate, federal, and professional standardsrequire documentation to include initial and ongoing assessments, any change in the patient’s condition, therapies given and patient response, patient teaching, and relevant statements by the patient. Question 4 A nursing unit has changed its documentation system to documenting by exception. How will this system save time? 1. It eliminateslengthy orrepetitive documentation. 2. It allowsflexibility and description in the documentation. 3. It allowsthe reader to easily locate information about a specific problem. 4. It allowsfor quick and easy retrieval of information. Correct Answer: 1 Rationale 1: Documenting by exception eliminates lengthy or repetitive documentation. Rationale 2: Flexible and descriptive documentation is an advantage of the narrative system. Rationale 3: PIE charting allows easy location of information about a specific problem. Rationale 4: The electronic health record allowsfor quick and easy retrieval of information. Question 5 A hospital is considering changing its documentation system to reduce the number of medication errors. Which system should the hospital investigate? 1. Problem, intervention, evaluation (PIE)system 2. Electronic medicalrecord 3. Problem-oriented medical record 4. Narrative system Correct Answer: 2 Rationale 1: The PIE system consists of a list of the patient’s problems, interventionstaken to alleviate the problems, and evaluation of the patient’s response to the interventions. This system does not have the specific benefit of reducing medication errors. Rationale 2: The electronic medical record decreases errors and allowsfor the reconciliation of the patient’s medications on admission, daily, and on discharge. Rationale 3: The five components ofthe problem-oriented medical record are baseline data, a problem list, a plan of care for each problem, multidisciplinary progress notes, and a discharge summary. This system does not have the specific benefit of reducing medication errors. Rationale 4: Narrative documentation does not have the specific benefit of reducing medication errors. Question 6 Which nursing activities are examples of independent functions of the nursing role? 1. Teaching a soon-to-be-discharged patient about the medication regimen that the health care provider has prescribed 2. Talking with the patient about his or her abilitiesto manage personal hygiene activities while in the usual state of health at home 3. Incorporating adaptive techniques into nursing care asrecommended by occupational therapy 4. Administering analgesic medication ordered by the health care provider 5. Introducing oneself to, and interviewing, the patient to collect data about physical health status Correct Answer: 2,5 Rationale 1: Teaching the patient about medications prescribed by the health care provider is an interdependent activity. Rationale 2: This activity is part of the assessment process, which is an independent activity that nurses may perform, based on their education and skills. Rationale 3: Working in coordination with another health team member is an interdependent activity. Rationale 4: Administering medication prescribed by the health care provider is an example of a dependent activity. Rationale 5: These activities are included in assessment, which is an independent activity that nurses may perform, based on their education and skills. Question 7 The nurse is caring for a 70-year-old patient who was just admitted to an inpatient rehabilitation center. The patient had required total parenteral nutrition for several days, but recently resumed and is tolerating a regular diet. She has another 4 days left in a course of intravenous antibioticsto complete treatment of a positive central line culture. Which nursing action, required in the care of this patient, is considered a dependent role function? 1. Requesting that the health care provider order a consult because the patient statesthat her dentures no longer fit properly and she has trouble chewing 2. Asking the nursing assistant to demonstrate to the patient how to operate the callsystem 3. Interviewing the patient to assess whether she needs assistance with getting out of bed 4. Administering the antibiotics prescribed by the health care provider Correct Answer: 4 Rationale 1: Assessing that the patient has a need that requires further assessment by other team members and communicating that need to the appropriate team member is an example of an interdependent activity. Rationale 2: Thisis an independent activity that nurses may perform or delegate, based on their and the delegate’s education and skills. Rationale 3: Assessment is an independent activity that nurses may perform, based on their education and skills. Rationale 4: Dependent activities are those prescribed by the health care provider and carried out by the nurse. Question 8 When asking a patient if a pain medication provided a few hours ago has been effective, the nurse is performing which step of the nursing process? 1. Planning 2. Implementation 3. Evaluation 4. Assessment Correct Answer: 3 Rationale 1: Planning consists of prioritizing among the chosen nursing diagnoses and determining interventions to move the patient to optimal health. Rationale 2: Implementation isthe actual “doing” step of the nursing process. In this case, implementation occurred when the medication was administered. Rationale 3: Evaluation focuses on a patient’s behavioral changes and compares them with the criteria stated in the objectives. It consists of both the patient’s status and the effectiveness of the nursing care. Both must be evaluated continuously, with the care plan modified as needed. Rationale 4: Assessment comprises examining the patient and identifying cues, collecting and analyzing data, and reaching conclusions. In this situation, assessment occurred when the nurse identified that the patient was in pain. Question 9 The nursing instructor knowsthat further education is needed when a student makes which statement? 1. “Assessment precedes nursing diagnosis and outcome identification.” 2. “Planning follows nursing diagnosis and outcome identification and precedes implementation.” 3. “Evaluation followsimplementation and precedes planning.” 4. “Planning follows assessment and precedes evaluation.” Correct Answer: 3 Rationale 1: The correct order is assessment, diagnosis, planning, implementation, and evaluation. Rationale 2: The correct order is assessment, diagnosis, planning, implementation, and evaluation. Rationale 3: The correct order is assessment, diagnosis, planning, implementation, and evaluation. Rationale 4: The correct order is assessment, diagnosis, planning, implementation, and evaluation. Question 10 A 16-year-old patient has been admitted for treatment of presumptive pelvic inflammatory disease. The patient’s hygiene is poor and she reports living “on the street” for a year. She is febrile and tachycardic and reports pain as 10 on the 1-to-10 scale. The nurse identifies Acute Pain as the priority nursing diagnosis. Which outcome statement is appropriate? 1. The patient’s comfort will be achieved and maintained. 2. The patient will be discharged to a safe living environment. 3. The patient will be reunited with her parents. 4. The patient’sinfection will be eradicated. Correct Answer: 1 Rationale 1: Achieving and maintaining comfort addresses the nursing diagnosis of acute pain related to possible pelvic inflammatory disease identified by the nurse. Rationale 2: The patient’s living environment is of concern but is not the correct outcome for the priority nursing diagnosis. Rationale 3: Reuniting the patient with her parents may not be a desired goal for this patient. It also does not match the nursing diagnosis chosen. Rationale 4: Eradication of the infection is a desired outcome but does not match the chosen nursing diagnosis. Question 11 While assessing a female patient from the Middle East, the nurse observesthat the patient makes no eye contact and answers questions by nodding or with only a few words. The nurse’s entry in the patient’srecord statesthat the patient “appearsto be frightened.” This isan example of which factor associated with assessment? 1. Personal interpretation 2. Subjective data 3. Nursing diagnosis 4. Objective data Correct Answer: 1 Rationale 1: This is the nurse’s personal interpretation of the patient’s behavior. It has not been validated with the patient. These behaviors may indicate a number of possibilities such as physical, mental, and emotional status or cultural and social norms. Rationale 2: A direct quote from the patient would be subjective data. Rationale 3: Thisstatement does not meet the criteria for a nursing diagnosis. Rationale 4: A description of the patient’s behavior such as “makes no eye contact” would be objective data. Question 12 The patient tells the nurse that everything “tastes funny” since starting a new medication, making eating unpleasant. The nurse has given this medication to other patients and has not heard this complaint from any of them. The nurse checks the drug reference again to learn whether this is a known side effect of the medication and reads that it is. This information may be helpful in making a nursing diagnosis and determining how best to address this problem. Which data from this scenario is considered subjective? 1. The nurse rechecksthe drug reference about known side effects of the medication. 2. The patient tellsthe nurse that everything “tastesfunny.” 3. The nurse reads that this medication can cause a metallic taste in some patients. 4. Other patients who have taken this medication have never reported thisside effect to the nurse. Correct Answer: 2 Rationale 1: Rechecking the drug reference is an example of obtaining factual information about the medication, not data about the patient. Rationale 2: The statement by the patient issubjective data because it reflects something that only the patient, not the nurse, can perceive. Rationale 3: That this medication can cause a metallic taste isfactual information about the medication, not data about the patient. Rationale 4: The nurse’s prior experience with this medication is not data about the patient. Question 13 Which statementrepresents a nursing diagnosis? 1. High risk for delayed maternal-infant bonding due to maternal-infant separation 2. Crohn’s disease 3. Hypertension 4. Appendicitis Correct Answer: 1 Rationale 1: This is an example of a nursing diagnosis. The statement indicates a clinical judgment that this new mother-baby couplet is at greater risk of experiencing a delay in bonding than other mother-baby couplets. Rationale 2: Crohn’s disease is a medical diagnosis. Rationale 3: Hypertension is a collaborative problem. Rationale 4: Appendicitis is a medical diagnosis. Question 14 Which statementsreflect collaborative problems? 1. Knowledge deficit related to infant safety as evidenced by mother leaving crib rail down 2. Sleep apnea 3. Neonatal abstinence syndrome 4. Gestational diabetes 5. Sleep pattern disturbance related to hospital environment and routines Correct Answer: 2,3,4 Rationale 1: The nurse can diagnose this knowledge deficit and use independent nursing interventions to address the problem. This is a nursing diagnosis. Rationale 2: Sleep apnea is a medical diagnosis and therefore a collaborative problem. Rationale 3: Neonatal abstinence syndrome is a medical diagnosis and therefore a collaborative problem. Rationale 4: Gestational diabetesis a medical diagnosis and therefore a collaborative problem. Rationale 5: The nurse can diagnose that a patient has disturbed sleep and can intervene to reduce noise and other disturbances in the environment. This is a nursing diagnosis. Question 15 The nurse is using critical thinking to better understand a patient. The nurse is working in which part of the nursing process? 1. Implementation 2. Nursing diagnosis and outcome identification 3. Assessment 4. Planning Correct Answer: 3 Rationale 1: Using critical thinking to reduce the risk of undesirable resultsis part of implementation. Rationale 2: Using critical thinking to identify actual and potential problems is associated with the diagnostic step of the nursing process. Rationale 3: The goal of assessment is to learn as much as possible about the patient within the context of the nurse-patient relationship. One characteristic of the nurse-patient relationship is the nurse’s continuous focus on better understanding of the patient. Rationale 4: Using critical thinking to make decisions about an action is associated with planning. Question 16 Which aspect of critical thinking would the nurse use when making a nursing diagnosis? 1. Making decisions about an action 2. Identifying potential and actual problems 3. Increasing the likelihood of obtaining good results 4. Getting a better understanding ofsomeone else Correct Answer: 2 Rationale 1: Making decisions about an action is associated with planning. Rationale 2: Identifying potential and actual problems is analogousto identifying nursing diagnoses, potential and actual. Rationale 3: Increasing the likelihood of obtaining good resultsisrelated to evaluation. Rationale 4: Getting a better understanding ofsomeone else is related to assessment. Question 17 Critical thinking empowers the nurse to recognize important situational cues and respond quickly to adapt interventions, optimizing their effectiveness and the likelihood of a good outcome. What is true about this aspect of critical thinking? 1. This method of thinking is similar to the way that a skilled nurse uses continued assessment and evaluation to adapt the patient’s care plan. 2. Using this method of critical thinking produces only one correct solution to a problem. 3. The need to change the plan of care indicates that critical thinking and the nursing process are not compatible. 4. The statement provesthat critical thinking is another term for the nursing process. Rationale 1: The nurse uses critical thinking to continually assess the patient and evaluate response to interventions, then making changes to the plan of care to improve outcomes. Rationale 2: Critical thinking does not imply that there is only one correct answer to a problem; rather it demands that the nurse looks at information related to the question from many different viewpoints to identify the next step. Rationale 3: Thinking critically about patient response to interventions encourages the nurse to change portions of the care plan that are not effective. Rationale 4: Critical thinking and the nursing process are not synonymous; critical thinking enhances and complements the nursing process but is not identical to it. Question 18 The nurse is using the Kardex to plan a patient’s care. What information would the nurse expect to find in this document? 1. Nursing notesfrom the previousshift 2. Schedule of diagnostic tests 3. Level of activity 4. Diet 5. IV therapy Correct Answer: 2,3,4,5 Rationale 1: Nursing notes are not found on the Kardex. Rationale 2: The patient’s schedule for diagnostic testing isrecorded on the Kardex. Rationale 3: The patient’s level of activity is recorded on the Kardex. Rationale 4: The diet prescribed for the patient is recorded on the Kardex. Rationale 5: The fluid, additives, and rate of IV therapy are recorded on the Kardex. Question 19 According to the Health Insurance Portability and Accountability Act (HIPAA), which persons have legal access to the patient’s health record? 1. The patient 2. Any nurses working on the unit where the patient is hospitalized 3. Any physician who has credentialsto admit patients to the hospital 4. The respiratory therapist who is providing inhalation therapy for the patient 5. The nuclear medicine technician who provided care during the patient’slast hospitalization Correct Answer: 1,4 Rationale 1: The information in the record belongs to the patient, who hasthe legal right to review it at any time. Rationale 2: The only nurses who have the legal right to review the record are the nurses involved with the patient’s care. Rationale 3: The only physicians who have the legal right to review the record are the physiciansinvolved in the patient’s care. Rationale 4: The respiratory therapist who isinvolved in the patient’s care has the legal right to review the patient’s chart. Rationale 5: If the technician is not involved in caring for the patient on this admission, he or she has no legal right to review the chart. Question 20 During a routine breast examination of a patient, the nurse notes a small amount of nipple discharge. What nursing actions are indicated? 1. Tell the patientshe may have cancer. 2. Send the specimen to the lab. 3. Ask the patient ifshe has noticed discharge before. 4. Collect a specimen on a slide. 5. Document the finding. Correct Answer: 2,3,4,5 Rationale 1: Telling the patientshe has cancer isinappropriate; discharge is not always a sign of cancer. Rationale 2: The nipple drainage would be sent to the lab for analysis. Rationale 3: The nurse would question if this discharge has occurred before and when it began. Rationale 4: The drainage should be collected on a specimen slide. Rationale 5: The nurse would document the finding so that future comparisons can be made if the drainage continues. Question 21 During a routine pelvic examination, the nurse instructs the patient to bear down. The nurse explains that this motion makes it easier to assess for which conditions? 1. Rectoceles 2. Prolapsed uterus 3. Vaginal tumors 4. Ovarian cysts 5. Cystoceles Correct Answer: 1,2,5 Rationale 1: Rectocele, or relaxation of the posterior vaginal wall over the rectum, is assessed by asking the patient to bear down so that the health care provider can determine the presence of the structures through the vagina. Rationale 2: Prolapsed uterus, or the protrusion of the uterusinto the vaginal wall, is assessed by asking the patient to bear down so that the health care provider can determine the presence of the structures through the vagina. Rationale 3: Vaginal tumors may be detected by visual inspection of the pelvis through a speculum device. Rationale 4: Ovarian cysts are palpated manually, and the patient does not have to bear down to determine their presence. Rationale 5: Cystocele, or relaxation of the anterior vaginal wall under the urinary bladder, is assessed by asking the patient to bear down so that the health care provider can determine the presence of the structures through the vagina. Question 22 The nurse is instructing a female patient about changes in sexual functioning that may result from the aging process. Which nursing diagnoses would the nurse incorporate into the plan of care for this patient regarding sexual intercourse? 1. Risk for Injury 2. Risk for Infection 3. Impaired Skin Integrity 4. Altered Tissue Perfusion 5. Alteration in Comfort Correct Answer: 1,2,3,5 Rationale 1: The patient could be at risk of injury due to thinning vaginal tissues. Rationale 2: With intercourse, the vaginal tissue may tear, and infection of the disrupted tissue could result. Rationale 3: Impaired Skin Integrity may result because of the thinning of the vaginal mucosa and loss of adipose tissue. Rationale 4: The aging process does not reduce the perfusion of the vaginal mucosa. Rationale 5: Intercourse may be painful because of the estrogen loss and drying of the vaginal mucosa. Question 23 A female patient who is experiencing hot flashes during menopause asksthe nurse how long they will last. Which information should the nurse provide? 1. Hot flashes do not occur after the first year of menopause. 2. Hot flashes usually occur once a month. 3. The patient may have hot flashes for up to 5 years. 4. Hot flashes generally disappear after the first 2 years of menopause. Correct Answer: 3 Rationale 1: Hot flashes are unpredictable and may last longer than 1 year. Rationale 2: There is no indication that hot flashes occur only once a month. Rationale 3: Hot flashes are unpredictable and may last up to 5 years, especially if the patient is not taking hormone replacement therapy. Rationale 4: Hot flashes may last longer than 2 years. Question 24 A young adult male asksthe nurse about the recommended frequency of testicular selfexams. How should the nurse respond? 1. “The more frequently exams are performed, the more beneficial they are.” 2. “You should have been taught to self-examine starting at age 12.” 3. “Not all experts believe that testicular self-examination is necessary or beneficial for young men.” 4. “It is essential that you perform this exam each month.” Correct Answer: 3 Rationale 1: Guidelines do not indicate that testicular self-exams are beneficial the more they are performed. Rationale 2: There is no indication that a 12-year-old should be taught testicular selfexamination. Rationale 3: Testicularself-exams for adolescents and young men have been shown to cause more harm than benefit, according to the United States Preventive Service Task Force (USPSTF). USPSTF guidelines state that routine exams should not be performed. Rationale 4: Not all experts believe that testicular exams are necessary for adolescents and young men. Question 25 A 20-year-old female asks the nurse when she should begin having pelvic examinations. Which question should the nurse ask before responding? 1. “Are you on any medications?” 2. “Do you have a boyfriend?” 3. “Are you sexually active?” 4. “Are you asking because you think you are pregnant?” Correct Answer: 3 Rationale 1: Asking about medications istoo broad a question and does not give the nurse information about the patient’s sexual practices. Rationale 2: Having a boyfriend does not alwaysindicate sexual activity. Rationale 3: The United States Preventive Services Task Force (USPSTF) recommends that pelvic examinations begin about 3 years after the initiation of sexual intercourse but no later than 21 years of age. Rationale 4: Pregnancy is a reason for a pelvic examination, but it is not the only reason. The nurse should also not assume that the patient may be pregnant. Question 26 The patient asks why the nurse is asking questions about her mother’s obstetrical history. Which rationale for this questioning should the nurse provide? 1. “If your mother smoked while she was pregnant with you, your risk of lung cancer is higher.” 2. “Use of medications to prevent miscarriage may have an impact on your health.” 3. “The government wantsto know for a genetic study.” 4. “If your mother had bleeding after delivery, you should avoid aspirin if you become pregnant.” Correct Answer: 2 Rationale 1: There is no correlation between smoking during pregnancy and the development of lung cancer in the child. Rationale 2: Daughters of women who took diethylstilbesterol (DES) are at higher risk of developing cancer of the vagina and cervix. Rationale 3: Thisis not a reason to collect thisinformation. Rationale 4: All pregnant women should avoid aspirin. There is no correlation between their mothers’ obstetric history and the need to avoid aspirin. Question 27 Which statement by a patient offersthe nurse information about moliminalsymptoms? 1. “I have headachesif I don’t eatregularly.” 2. “When I was pregnant, my feet and ankles were swollen every day.” 3. “My last boyfriend gave me hepatitis.” 4. “I get terrible cramps with my periods.” Correct Answer: 4 Rationale 1: Headaches that occur when meals are missed may be due to hypoglycemia. This is not a moliminal symptom. Rationale 2: Swelling of the feet and ankles during pregnancy is not a moliminal symptom. Rationale 3: Hepatitis is not associated with moliminal symptoms. Rationale 4: Symptoms associated with menses are moliminalsymptoms. Question 28 On assessment the nurse notes that a patient’s urinary opening is on the ventral side of the penis. How should the nurse document this finding? 1. Hypospadias 2. Hydrocele 3. Cryptorchidism 4. Varicocele Correct Answer: 1 Rationale 1: In hypospadias, the urinary opening is on the ventral or bottom side of the penis. Rationale 2: A hydrocele is swelling due to fluid accumulation in the scrotum. Rationale 3: Cryptorchidism isthe presence of an undescended testicle. Rationale 4: Varicocele is varicosities of the veins of the scrotum. Question 29 Which precautionsshould the nurse conducting an assessment of the reproductive system take to avoid the cremasteric reflex? 1. Ask the patient to cough during the exam for inguinal hernia. 2. Ask the patient to breathe in slowly through the nose and out through the mouth. 3. Conduct the examination in a warm room. 4. Lubricate the finger used for the prostate exam. Correct Answer: 3 Rationale 1: Coughing during the exam for inguinal hernia intensifies the bulging. Thisis not the cremasteric reflex. Rationale 2: Slow breathing does not eliminate the cremasteric reflex. Rationale 3: The cremasteric reflex, in which the testiclesrise in the scrotum to the abdominal cavity, can be reduced by conducting the exam in a warm room. Rationale 4: The cremasteric reflex is not related to the prostate exam. Question 30 During assessment, the nurse notes a third nipple about 4 inches below the patient’s costal margin. What nursing action is indicated? 1. Ask the patient when this nipple appeared. 2. Document this normal variant. 3. Discussthe finding with the health care provider because these nipples are commonly malignant. 4. Look for additional nipples on the patient’s back. Correct Answer: 2 Rationale 1: Patients are born with this condition. Rationale 2: Supernumerary nipples are normal variants but should be documented in the medical record. Rationale 3: Thisis a benign condition. Rationale 4: These extra nipples appear down the “milk lines” that run from the axilla across the nipple and down the abdomen to the groin. They are not found on the back. Question 31 The patient has respiratory difficulty due to changes in anatomic dead space. The nurse plans interventions based on changes in which physiological process? 1. Beginning of the gas exchange process 2. Neutralizing the air 3. Filtering the air 4. Separating the air Correct Answer: 3 Rationale 1: The anatomical dead space includesthe structures from the nose to the terminal bronchioles. Air flows through the anatomical dead space, but these structures do not participate in gas exchange. Rationale 2: The anatomical dead space includesthe structures from the nose to the terminal bronchioles. Air flows through this space, but it is not neutralized. Rationale 3: The trachea is part of the anatomical dead space. It traps particulate matter to keep it from entering the lungs. Rationale 4: The anatomical dead space includesthe structures from the nose to the terminal bronchioles. The air is not separated in these structures. Question 32 During an assessment, a patient begins to cough. How would the nurse evaluate thisfinding? 1. The patient has a cold. 2. The patient is nervous. 3. Something other than air was entering the larynx. 4. The patient is not fully conscious. Correct Answer: 3 Rationale 1: A cough does not indicate the presence of a cold. Additional assessment would be necessary. Rationale 2: A cough is not sufficient assessment data to determine that a patient is nervous. Rationale 3: If anything other than air entersthe larynx, a cough reflex expels the foreign substance before it can enter the lungs. Rationale 4: The protective reflex of coughing may not be present if the person is unconscious. A cough is not enough data to determine level of consciousness. Question 33 A patient is diagnosed with a low iron count. The nurse would be alert for which finding associated with this condition? 1. Increased carbon dioxide in the blood 2. Nausea 3. Anxiety 4. Poortissue oxygenation Correct Answer: 4 Rationale 1: Low iron would not increase carbon dioxide levelsin the blood. Rationale 2: Nausea is not generally associated with low iron count. Rationale 3: Anxiety is not generally associated with low iron count. Rationale 4: Oxygen is carried in the blood either bound to hemoglobin or dissolved in the plasma. Oxygen is not very soluble in water,so almost all oxygen that enters the blood from the respiratory system is carried to the cells of the body by hemoglobin. Question 34 During the palpation of a patient’s chest for expansion, the nurse notices a decrease in expansion of the right side. This finding is consistent with which condition? 1. Emphysema 2. Pneumothorax 3. Flail chest 4. Heart failure 5. Influenza Correct Answer: 2,3 Rationale 1: Bilateral chest expansion is decreased in emphysema. Rationale 2: Thoracic expansion is altered on the affected side in patients with pneumothorax. Rationale 3: One side of the chest would not expand at the correct time if the patient has a flail chest. Rationale 4: Heart failure does not result in a change in chest expansion. Rationale 5: Thoracic expansion is not affected by influenza. Question 35 The nurse is preparing to auscultate a patient’slungs. Which breath sounds would the nurse consider abnormal? 1. Crackles 2. Vesicular breath sounds 3. Bronchovesicular breath sounds 4. Wheezes 5. Bronchial breath sounds Correct Answer: 1,4 Rationale 1: Crackles are caused by airways that collapse during expiration and “pop” open during inspiration or by air bubbles passing through fluid. They are not normal breath sounds. Rationale 2: Vesicular breath sounds are the soft, low-pitched sounds heard over the majority of lung fields. They are normal. Rationale 3: Bronchovesicular breath sounds represent air movement in the moderate airways between the main bronchi and smaller airways. They are normal breath sounds. Rationale 4: Wheezes are continuous musicalsounds caused by air flowing across airwaysthat are narrowed or obstructed. They are abnormal breath sounds. Rationale 5: Bronchial breath sounds are heard over the major airways and are normal. Question 36 During a bronchoscopy, the nurse is to initially give 1.5 mg of midazolam hydrochloride (Versed) and another 1.5 mg of Versed in 2 minutes. Based on a concentration of 5 mg/mL, the nurse will draw up a total of mL for the two doses. Correct Answer: 0.6
