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. A patient is admitted to the emergency department with an open stab wound to the left chest. What is the first action that the nurse should take?
- A. Position the patient so that the left chest is dependent
- B. Tape a nonporous dressing on three sides over the chest wound
- C. Cover the sucking chest wound firmly with an occlusive dressing
- D. Keep the head of the patient's bed at no more than 30 degrees elevation
Correct answer: B
Rationale: The correct initial action for a patient with an open stab wound to the chest is to tape a nonporous dressing on three sides over the chest wound. This dressing technique allows air to escape during expiration but prevents air from entering the pleural space during inspiration, helping to prevent tension pneumothorax. Placing the patient so that the left chest is dependent or covering the wound with an occlusive dressing can trap air in the pleural space, leading to tension pneumothorax. Keeping the head of the bed elevated at 30 to 45 degrees helps facilitate breathing and is not the first action to take when managing an open chest wound.
3. A patient comes to the emergency department with abdominal pain. Work-up reveals the presence of a rapidly enlarging abdominal aortic aneurysm. Which of the following actions should the nurse expect?
- A. The patient will be admitted to the medicine unit for observation and medication.
- B. The patient will be admitted to the day surgery unit for sclerotherapy.
- C. The patient will be admitted to the surgical unit and resection will be scheduled.
- D. The patient will be discharged home to follow-up with his cardiologist in 24 hours.
Correct answer: C
Rationale: A rapidly enlarging abdominal aortic aneurysm is at significant risk of rupture, which can be life-threatening. The standard treatment for a rapidly enlarging abdominal aortic aneurysm is surgical intervention to prevent rupture. Therefore, the appropriate action for the nurse to expect is that the patient will be admitted to the surgical unit, and resection will be scheduled. Observation and medication (Choice A) are not sufficient for a rapidly enlarging aneurysm, and sclerotherapy (Choice B) is not typically used for aortic aneurysms. Discharging the patient home (Choice D) would be inappropriate and dangerous given the risk of rupture.
4. Which of the following clients is most appropriate for receiving telemetry?
- A. A client with syncope potentially related to cardiac dysrhythmia
- B. A client with unstable angina
- C. A client with sinus rhythm and PVCs
- D. A client who had a myocardial infarction 6 hours ago
Correct answer: A
Rationale: Telemetry is used to monitor the cardiac rhythms of clients with potentially unstable conditions or those rhythms that affect activities. Clients with syncope potentially related to cardiac dysrhythmia require continuous monitoring to detect any potential life-threatening dysrhythmias. Unstable angina can be monitored in a telemetry unit, but syncope with potential cardiac causes takes precedence. Clients with sinus rhythm and PVCs may not necessitate telemetry unless there are further indications of instability. A client who had a myocardial infarction 6 hours ago is typically monitored in an intensive care unit rather than a telemetry unit.
5. The nurse monitors a patient after chest tube placement for a hemopneumothorax. The nurse is most concerned if which assessment finding is observed?
- A. A large air leak in the water-seal chamber
- B. 400 mL of blood in the collection chamber
- C. Complaint of pain with each deep inspiration
- D. Subcutaneous emphysema at the insertion site
Correct answer: B
Rationale: The nurse should be most concerned if 400 mL of blood is observed in the collection chamber as it may indicate the patient is at risk of developing hypovolemic shock. A large air leak in the water-seal chamber is expected initially after chest tube placement for a pneumothorax. While pain with deep inspiration should be treated, it is not as urgent as the risk of continued hemorrhage. Subcutaneous emphysema is not uncommon in a patient with pneumothorax and is usually harmless. However, a large amount of blood in the collection chamber is a more critical finding that requires immediate attention to prevent potential complications.
