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. To palpate the liver during a head-to-toe physical assessment, the nurse should
- A. put pressure on the biopsy site using a sandbag
- B. elevate the head of the bed to facilitate breathing
- C. place the patient on the right side with the bed flat
- D. check the patient's post-biopsy coagulation studies
Correct answer: C
Rationale: To palpate the liver effectively during a head-to-toe physical assessment, the patient should be positioned on the right side with the bed flat. This position helps to splint the biopsy site and allows for proper palpation of the liver. Elevating the head of the bed has no direct relevance to palpating the liver. Checking coagulation studies is done before the biopsy and is unrelated to palpation. Putting pressure on the biopsy site using a sandbag is not an appropriate way to facilitate liver palpation as it does not provide the necessary support and stabilization needed for the procedure.
3. The clinic nurse is assessing jaundice in a child with hepatitis. Which anatomical area would provide the best data regarding the presence of jaundice?
- A. The nail beds.
- B. The skin in the sacral area.
- C. The skin in the abdominal area.
- D. The membranes in the ear canal.
Correct answer: A
Rationale: Jaundice, if present, can be best assessed in areas such as the sclera, nail beds, and mucous membranes due to the yellowing of these tissues. The nail beds specifically provide a good indication of jaundice. The skin in the sacral area (Option B) is not typically the best area for assessing jaundice as it is less visible and not as reliable as the nail beds. The skin in the abdominal area (Option C) may show generalized jaundice, but the nail beds are more specific for detecting early signs. Lastly, assessing the membranes in the ear canal (Option D) is not a standard method for evaluating jaundice; the sclera and nail beds are more commonly used for this purpose.
4. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is
- A. Surgical repair of a diseased coronary artery.
- B. Placement of an automatic internal cardiac defibrillator.
- C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow.
- D. Non-invasive radiographic examination of the heart.
Correct answer: C
Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.
5. The patient in the emergency room has a history of alprazolam (Xanax) abuse and abruptly stopped taking Xanax about 24 hours ago. He presents with visible tremors, pacing, fear, impaired concentration, and memory. Which intervention takes priority?
- A. Have the patient lie down on a stretcher with bed rails raised
- B. Offer the patient a cup of water and a small amount of food
- C. Reassure the patient about his well-being
- D. Inform the physician about the patient's Xanax withdrawal
Correct answer: A
Rationale: The 1-4 day period after Xanax withdrawal is critical as it poses the highest risk of life-threatening seizures. Alprazolam is a benzodiazepine, and sudden cessation can lead to severe withdrawal symptoms. The patient's visible tremors, fear, pacing, and cognitive impairment indicate a state of heightened distress and potential seizure risk. Placing the patient on a stretcher with raised bed rails is essential for seizure precautions, ensuring safety and preventing injury during a potential seizure. Offering water and food, reassuring the patient, or informing the physician about Xanax withdrawal are not immediate priorities compared to managing the risk of seizures in this high-risk situation.
