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. The nurse develops a plan of care to prevent aspiration in a high-risk patient. Which nursing action will be most effective?
- A. Turn and reposition immobile patients at least every 2 hours.
- B. Place patients with altered consciousness in side-lying positions.
- C. Monitor for respiratory symptoms in immunosuppressed patients.
- D. Insert nasogastric tube for feedings in patients with swallowing problems.
Correct answer: B
Rationale: To prevent aspiration in a high-risk patient, the most effective nursing action is to place patients with altered consciousness in side-lying positions. This position helps decrease the risk of aspiration as it prevents pooling of secretions and facilitates drainage. Turning and repositioning immobile patients every 2 hours is essential for preventing pressure ulcers and improving circulation but does not directly address the risk of aspiration. Monitoring respiratory symptoms in immunosuppressed patients is crucial to detect pneumonia early, but it does not directly prevent aspiration. Inserting a nasogastric tube for feedings in patients with swallowing problems may be necessary for nutritional support but does not address the risk of aspiration directly. Patients at high risk for aspiration include those with altered consciousness, difficulty swallowing, and those with nasogastric intubation, among others. Placing patients with altered consciousness in a side-lying position is a key intervention to reduce the risk of aspiration in this population. Other high-risk groups for aspiration include those who are seriously ill, have poor dentition, or are on acid-reducing medications.
3. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?
- A. A 20-year-old woman with unexplained joint pain and a low BMI.
- B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
- C. A 67-year-old man who had open-heart surgery 4 years ago.
- D. A 40-year-old woman in a hypomanic state for the last 2 days.
Correct answer: A
Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.
4. For a 6-year-old child hospitalized with moderate edema and mild hypertension associated with acute glomerulonephritis (AGN), which one of the following nursing interventions would be appropriate?
- A. Institute seizure precautions
- B. Weigh the child twice per shift
- C. Encourage the child to eat protein-rich foods
- D. Relieve boredom through physical activity
Correct answer: A
Rationale: Institute seizure precautions. The severity of the acute phase of AGN is variable and unpredictable; therefore, a child with edema, hypertension, and gross hematuria may be subject to complications, and anticipatory preparation such as seizure precautions is needed. Weighing the child twice per shift may be necessary for monitoring fluid balance but is not specifically related to the complications of AGN. Encouraging the child to eat protein-rich foods is important for overall nutrition but does not directly address the potential complications of AGN. Relieving boredom through physical activity is beneficial for overall well-being but is not the priority in this situation where seizure precautions are essential.
5. While caring for a patient with respiratory disease, the nurse observes that the patient's SpO2 drops from 93% to 88% while the patient is ambulating in the hallway. What is the priority action of the nurse?
- A. Notify the healthcare provider
- B. Document the response to exercise
- C. Administer the PRN supplemental O2
- D. Encourage the patient to pace activity
Correct answer: C
Rationale: The drop in SpO2 to 88% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. Administering PRN supplemental oxygen is the priority action to correct the hypoxemia and ensure adequate oxygenation during activity. Notifying the healthcare provider can be done after stabilizing the patient's oxygen levels. Documenting the response to exercise is important but secondary to addressing the immediate hypoxemia. Encouraging the patient to pace activity is not sufficient to address the acute drop in SpO2 and provide the necessary oxygen support.
