NCLEX RN EXAM QUESTIONS & ANSWERS 2023 UPDATE!!!

Question: 31 A client had a myocardial infarction 5 days ago. His physician has ordered an echocardiogram to determine how his myocardial infarction has affected his ventricular wall motion. When the client asks if this test is painful, an appropriate response is: A. "No, but you must be able to ride on a stationary bicycle while the test is being performed." B. "No, but you will have to lie still and the gel that is used may be cool." C. "Yes, but your physician will be there and will order pain medicine for you." D. "Your physician has ordered medicine, which you will be given before you go for the test, which will make you sleepy." Answer: B Explanation: (A) Riding a stationary bicycle or walking on a treadmill is done during a stress test. (B) During an echocardiogram, the client must lie supine while a technician performs the test. To perform the test, the technician uses a conductive gel and a transducer to obtain ultrasound tracings of the heart. (C) A physician need not be present during an echocardiogram, and it is neither invasive nor painful. (D) There is no premedication required for an echocardiogram. Question: 32 A 55-year-old man has recently been diagnosed with hypertension. His physician orders a low- sodium diet for him. When he asks, "What does salt have to do with high blood pressure?” the nurse’s initial response would be: A. "The reason is not known why hypertension is associated with a high-salt diet." B. "Large amounts of salt in your diet can cause you to retain fluid, which increases your blood pressure." C. "Salt affects your blood vessels and causes your blood pressure to be high." D. "Salt is needed to maintain blood pressure, but too much causes hypertension." Answer: B Explanation: (A) This response is untrue. (B) Decreasing salt intake reduces fluid retention and decreases blood pressure. (C) Salt does not have an effect on the blood vessels themselves, but on fluid retention, which accompanies salt intake. (D) This response is untrue. Question: 33 A 19-year-old client fell off a ladder approximately 3 ft to the ground. He did not lose consciousness but was taken to the emergency department by a friend to have a scalp laceration sutured. The nurse instructs the client to: A. Clean the sutured laceration twice a day with povidone- iodine (Betadine) B. Remove his scalp sutures after 5 days C. Return to the hospital immediately if he develops confusion, nausea, or vomiting D. Take meperidine 50 mg po q46h prn for headache Answer: C Explanation: (A) Povidone-iodine is very irritating to skin and should not be routinely used. (B) Sutures should not be removed by the client. (C) Confusion, nausea, vomiting, and behavioral changes may indicate increasing intracranial pressure as a result of intracerebral bleeding. (D) Use of a narcotic opiate such as meperidine is not recommended in clients with a possible head injury because it may produce sedation, pupil changes, euphoria, and respiratory depression, which may mask the signs of increasing intracranial pressure. Question: 34 A male client has asthma and his physician has prescribed beclomethasone (Vanceril) 3 puffs tid in addition to his other medications. After taking his beclomethasone, the client should be instructed to: A. Clean his inhaler with warm water and soak it in a10% bleach solution B. Drink a glass of water C. Sit and rest D. Use his bronchodilator inhaler Answer: B Explanation: (A) Inhalers should be cleaned once a day. They should be taken apart, washed in warm water, and dried according to manufacturer’s instructions. Soaking in bleach is inappropriate. (B) A common side effect of inhaled steroid preparations is oral candidal infection. This can be prevented by drinking a glass of water or gargling after using a steroid inhaler. (C) There is nothing wrong with sitting and resting after using a steroid inhaler, but it is not necessary. (D) If a person is using a steroid inhaler as well as a bronchodilator inhaler, the bronchodilator shouldalways be used first. The reason for this is that the bronchodilator opens up the person’s airways so that when the steroid inhaler is used next, there will be better distribution of medication. Question: 35 A 70-year-old client has pneumonia and has just had a respiratory arrest. He has just been intubated with an 8- mm endotracheal tube. During auscultation of his chest, breath sounds were found to be absent on the left side. The nurse identifies the most likely cause of this as: A. Inappropriate endotracheal tube size B. Left-sided pneumothorax C. Right mainstem bronchus intubation D. Pneumonia Answer: C Explanation: (A) Appropriate endotracheal tube sizes for adults range from 7.08.5 mm. (B) Pneumothorax could be indicated by an absence of breath sounds on the affected side. However, in a recently intubated client, the first priority would be to consider tube malposition. (C) During intubation, the right mainstem bronchus can be inadvertently entered if the endotracheal tube is inserted too far. Left mainstem bronchus intubation almost never occurs because of the angle of the left mainstem bronchus. (D) Breath sounds for someone with pneumonia may be decreased over the areas of consolidation. However, in a recently intubated client, the first priority would be to consider tube malposition. Question: 36 A 55-year-old client is unconscious, and his physician has decided to begin tube feeding him using a smallbore silicone feeding tube (Keofeed, Duo- Tube). After the tube is inserted, the nurse identifies the most reliable way to confirm appropriate placement is to: A. Aspirate gastric contents B. Auscultate air insufflated through the tube C. Obtain a chest x-ray D. Place the tip of the tube under water and observe for air bubbles Answer: C Explanation: (A) Aspiration of gastric contents is usually a reliable way to verify tube placement. However, if the client has dark respiratory secretions from bleeding, tube feedings could be mistaken for respiratory secretions; in other words, aspirating an empty stomach is less reliable in this instance. In addition, it is common for small-bore feeding tubes to collapse when suction pressure is applied. (B) Insufflation of air into large-bore nasogastric tubes can usually be clearly heard. In small-bore tubes, it is more difficult to hear air, and it is difficult to distinguish between air in the stomach and air in the esophagus. (C) A chest x-ray is the most reliable means to determine placement of small-bore nasogastric tubes. (D) Observing for air bubbles when the tip is held under water is an unreliable means to determine correct tube placement for all types of nasogastric tubes. Air may come from both the respiratory tract and the stomach, and the client who is breathing shallowly may not force air out of the tube into the water. Question: 37 A client was admitted with rib fractures and a pneumothorax, which were sustained as a result of a motor vehicle accident. A chest tube was placed on the left side to reinflate his lung, and he was transferred to a client unit. Twenty-four hours after admission he continues to have bloody sputum, develops increasing hypoxemia, and his chest x-ray shows patchy infiltrates. The nurse analyzes these symptoms as being consistent with: A. Pneumonia B. Pulmonary contusions C. Pulmonary edema D. Tension pneumothorax Answer: B Explanation: (A) Pneumonia may be reflected by patchy infiltrates. In addition, fever, an increasing white blood cell count, and copious sputum production would be present. (B) Blunt chest traumacauses a bruising process in which interstitial and alveolar edema and hemorrhage occur. This is manifest by gradual deterioration over 24 hours of arterial blood gases and the continued production of bloody sputum. Patchy infiltrates are evident on chest xray 24 hours postinjury. (C) Pulmonary edema usually results from left heart failure. It is manifest by pink, frothy sputum; increasing dyspnea; tachycardia; and crackles on auscultation. (D) Tension pneumothorax is a potential complication for someone with rib fractures and a chest tube. It is manifest by diminished breath sounds on the affected side, rapidly deteriorating arterial blood gases in the presence of an open airway, and shock that is unexplained by other injuries. Question: 38 A 66-year-old female client has smoked 2 packs of cigarettes per day for 20 years. Her arterial blood gases on room air are as follows: pH 7.35; PO2 70 mm Hg; PCO2 55 mm Hg; HCO3 32 mEq/L. These blood gases reflect: A. Compensated metabolic acidosis B. Compensated respiratory acidosis C. Compensated respiratory alkalosis D. Uncompensated respiratory acidosis Answer: B Explanation: (A) In compensated metabolic acidosis, the pH level is normal, the PCO2level is decreased, and the HCO3level is decreased. The client’s primary alteration is an inability to remove excess acid via the kidneys. The lungs compensate by hyperventilating and decreasing PCO2. (B) In compensated respiratory acidosis, the pH level is normal, the PCO2level is elevated, and the HCO3level is elevated. The client’s primary alteration is an inability to remove CO2from the lungs, so over time, the kidneys increase reabsorption of HCO3to buffer the CO2. (C) In compensated respiratory alkalosis, the pH level is normal, the PCO2level is decreased, and the HCO3level is decreased. The client’s primary alteration is hyperventilation, which decreases PCO2. The client compensates by increasing the excretion of HCO3from the body. (D) In uncompensated respiratory acidosis, the pH level is decreased, the PCO2level is increased, and the HCO3level is normal. The client’s primary alteration is an inability to remove CO2from the lungs. The kidneys have not compensated by increasing HCO3reabsorption. Question: 39 A female client who has chronic obstructive pulmonary disease (COPD) has presented in the emergency department with cough productive of yellow sputum and increasing shortness of breath. On room air, her blood gases are as follows: pH 7.30 mm Hg, PCO2 60 mm Hg, PO2 55 mm Hg, HCO3 32 mEq/L. These arterial blood gases reflect: A. Compensated respiratory acidosis B. Normal blood gases C. Uncompensated metabolic acidosis D. Uncompensated respiratory acidosis Answer: D Explanation: (A) In compensated respiratory acidosis, the pH level is normal, the PCO2level is elevated, and the HCO3level is elevated. The client’s primary alteration is an inability to remove CO2from the lungs, so over time, the kidneys increase reabsorption of HCO3to buffer the CO2. (B) Normal ranges for arterial blood gases for adults and children are as follows: pH 7.357.45, PO mm Hg, PCO23545 mm Hg, HCO32128 mEq/L. (C) In uncompensated metabolic acidosis the pH level is decreased, the PCO2level is normal, and the HCO3level is decreased. The client’s primary alteration is an inability to remove excess acid via the kidneys. The lungs are unable to clear the increased acid. (D) In uncompensated respiratory acidosis, the pH level is decreased, the PCO2level is increased, and the HCO3level is normal. In a person with long-standing COPD, the HCO3level will rise gradually over time to compensate for the gradually increasing PCO2, and the person’s pH level will be normal. When a person with COPD becomes acutely ill, the kidneys do not have time to increase the reabsorption of HCO3, so the person’s pH level will reflect acidosis even though the HCO3is elevated. Question: 40 A 19-year-old client has sustained a C-7 fracture, which resulted in his spinal cord being partially transected. By 2 weeks’ postinjury, his neck has been surgically stabilized, and he has been transferred from the intensive care unit. A potential life-threatening complication the nurse monitors the client for is: A. Autonomic dysreflexia B. Bradycardia C. Central cord syndrome
