NCLEX RN Exam Review Answers
1. Mr. L was working in his garage at home and had an accident with a power saw. He is brought into the emergency department by a neighbor with a traumatic hand amputation. What is the first action of the nurse?
- A. Place a tourniquet at the level of the elbow
- B. Apply direct pressure to the injury
- C. Administer a bolus of 0.9% Normal Saline
- D. Elevate the injured extremity on a pillow
Correct answer: B
Rationale: The correct first action for the nurse in this scenario is to apply direct pressure to the injury. When a client presents with traumatic hand amputation causing excessive bleeding, the immediate goal is to control the bleeding. Applying direct pressure with a sterile dressing helps to stem the flow of blood and stabilize the patient. Placing a tourniquet at the level of the elbow should be avoided initially as it may lead to further complications such as tissue damage. Administering a bolus of 0.9% Normal Saline is not the priority in this situation where hemorrhage control is crucial. Elevating the injured extremity on a pillow does not address the primary concern of controlling the bleeding and stabilizing the patient.
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. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?
- A. The bicarbonate level (HCO3) is 31 mEq/L
- B. The arterial oxygen saturation (SaO2) is 92%
- C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
- D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg
Correct answer: D
Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.
4. A patient is diagnosed with both human immunodeficiency virus (HIV) and active tuberculosis (TB) disease. Which information obtained by the nurse is most important to communicate to the healthcare provider?
- A. The Mantoux test induration measured 7 mm.
- B. The chest x-ray revealed infiltrates in the lower lobes.
- C. The patient is receiving antiretroviral therapy for HIV infection.
- D. The patient has a cough producing blood-tinged mucus.
Correct answer: C
Rationale: The most critical information to communicate to the healthcare provider in a patient diagnosed with both HIV and active TB disease is that the patient is receiving antiretroviral therapy for HIV infection. This is crucial because drug interactions can occur between antiretrovirals used to treat HIV infection and medications used to treat TB. By informing the healthcare provider about the antiretroviral therapy, potential interactions can be assessed and managed effectively to optimize patient care. The other data provided, such as the Mantoux test result, chest x-ray findings, and presence of blood-tinged mucus, are important clinical information but are expected in a patient with coexisting HIV and TB and do not directly impact potential drug interactions between antiretrovirals and TB medications.
5. A patient asks the nurse whether he is a good candidate to use a CPAP machine. The nurse reviews the client's history. Which condition would contraindicate the use of a CPAP machine?
- A. The patient is in the late stage of dementia.
- B. The patient has a history of bronchitis.
- C. The patient has had suicidal gestures/attempts in the past.
- D. The patient is on beta-blockers.
Correct answer: A
Rationale: The correct answer is that the patient is in the late stage of dementia. In late-stage dementia, individuals may have an inability to follow commands and understand instructions independently, which are essential for proper installation and use of a CPAP machine. This makes using a CPAP machine challenging and potentially ineffective for patients in this condition. Choice B, having a history of bronchitis, does not contraindicate the use of a CPAP machine. In fact, CPAP therapy can be beneficial for patients with respiratory conditions like bronchitis. Choice C, a history of suicidal gestures/attempts, while concerning for the patient's mental health, does not directly contraindicate the use of a CPAP machine. Choice D, being on beta-blockers, is not a contraindication for CPAP machine use. Beta-blockers are commonly used medications for various conditions and do not interfere with the use of a CPAP machine.
