NCLEX RN Exam Review Answers
1. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?
- A. Heparin will dissolve clots that you have.
- B. Heparin will reduce the platelets that make your blood clot.
- C. Heparin will work better than warfarin.
- D. Heparin will prevent new clots from developing.
Correct answer: D
Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.
2. Clinical manifestations of asthma include:
- A. Decreased expiratory time
- B. Increased peak expiratory flow
- C. Increased use of accessory muscles
- D. Increased oxygen saturation
Correct answer: C
Rationale: Clinical manifestations of asthma include increased use of accessory muscles, increased expiratory time, increased peak expiratory flow, and decreased oxygen saturation. Choice A, 'Decreased expiratory time,' is incorrect because asthma typically presents with increased expiratory time due to airway obstruction. Choice B, 'Increased peak expiratory flow,' is incorrect as asthma commonly leads to decreased peak expiratory flow due to airway constriction. Choice D, 'Increased oxygen saturation,' is incorrect because asthma exacerbations often result in decreased oxygen saturation levels.
3. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?
- A. The medication will reduce the risk of aspiration.
- B. The medication will inhibit the development of gastric ulcers.
- C. The medication will prevent irritation of the enlarged veins.
- D. The medication will decrease nausea and improve appetite.
Correct answer: C
Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.
4. The nurse palpates the posterior chest while the patient says 99 and notes absent fremitus. What action should the nurse take next?
- A. Auscultate anterior and posterior breath sounds bilaterally
- B. Encourage the patient to turn, cough, and deep breathe
- C. Review the chest x-ray report for evidence of pneumonia
- D. Palpate the anterior chest and observe for barrel chest
Correct answer: A
Rationale: To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as '99'. After noting absent fremitus, the nurse should then auscultate the lungs to assess for the presence or absence of breath sounds. Absent fremitus may be noted with conditions like pneumothorax or atelectasis. The vibration is increased in conditions such as pneumonia, lung tumors, thick bronchial secretions, and pleural effusion. Encouraging the patient to turn, cough, and deep breathe is an appropriate intervention for atelectasis, but assessing breath sounds takes priority. Fremitus is decreased if the hand is farther from the lung or the lung is hyperinflated (barrel chest). Palpating the anterior chest for fremitus is less effective due to the presence of large muscles and breast tissue, making auscultation a more appropriate next step.
5. The nurse completes discharge teaching for a patient who has had a lung transplant. The nurse evaluates that the teaching has been effective if the patient makes which statement?
- A. I will make an appointment to see the doctor every year.
- B. I will stop taking the prednisone if I experience a dry cough.
- C. I will not worry if I feel a little short of breath with exercise.
- D. I will call the health care provider right away if I develop a fever.
Correct answer: D
Rationale: The correct answer is, 'I will call the health care provider right away if I develop a fever.' It is crucial for patients who have undergone a lung transplant to be vigilant about any signs of infection or rejection. A low-grade fever can be an early indicator of such complications, requiring immediate medical attention. While annual follow-up visits are necessary, they are not sufficient for monitoring acute changes in health post-transplant. Stopping prednisone abruptly can lead to rejection and should only be done under healthcare provider guidance. Feeling short of breath with exercise should be reported as it can indicate potential issues. Recognizing and addressing symptoms promptly is key to successful post-transplant care, and in this case, calling the healthcare provider immediately for a fever is the most appropriate action.
