NCLEX RN Exam Review Answers
1. You have noticed that the last several patients you have cared for have had questionable blood pressure readings from their arterial lines. When checked against cuff pressures, a discrepancy has been noted, and further investigation has revealed faulty transducers. This is not the first product issue with this company. What positive step could you take to help resolve this situation?
- A. Use the old stock from a previous company
- B. Verify the cuff pressures every hour to ensure accuracy
- C. Notify the risk manager
- D. Form a peer workgroup to evaluate new products
Correct answer: D
Rationale: Forming a peer workgroup to evaluate new products would be an excellent opportunity for collaboration among peers, management, and the purchasing department. When clinicians are engaged to work toward solutions that address patient care issues, they experience more empowerment and control over their work environments. Choice A is incorrect because using old stock from a previous company does not address the root cause of the faulty transducers from the current company. Choice B is incorrect as verifying cuff pressures every hour does not directly address the issue of faulty transducers. Choice C is less effective than forming a peer workgroup as it involves only notifying the risk manager without involving a collaborative effort to resolve the product issue.
2. A client is discharged following hospitalization for congestive heart failure. The nurse teaching the family suggests they encourage the client to rest frequently in which of the following positions?
- A. High Fowler's
- B. Supine
- C. Left lateral
- D. Low Fowler's
Correct answer: A
Rationale: The correct answer is "High Fowler's" position. Sitting in a chair or resting in a bed in a high Fowler's position decreases the cardiac workload and facilitates breathing. This position helps reduce the work of breathing and promotes optimal lung expansion, making it easier for the client to breathe. Supine position (choice B) is lying flat on the back and may not be ideal for clients with congestive heart failure as it can increase pressure on the heart. Left lateral position (choice C) is commonly used for promoting circulation in clients with certain conditions but is not the most appropriate for congestive heart failure. Low Fowler's position (choice D) is not recommended as it does not provide the same benefits in terms of reducing cardiac workload and easing breathing as the high Fowler's position.
3. A client in labor has an electronic fetal monitor attached to the abdomen, and the nurse notes that the baby's heart rate slows down during each contraction, returning to normal limits only after the contraction is complete. Which type of fetal heart rate change does this pattern describe?
- A. Variable decelerations
- B. Late decelerations
- C. Early decelerations
- D. Accelerations
Correct answer: B
Rationale: Late decelerations refer to a pattern where the baby's heart rate decreases during contractions and does not return to normal until after the contraction ends. This is considered a non-reassuring sign as it indicates potential fetal distress. Late decelerations are associated with uteroplacental insufficiency, and immediate medical attention is required. Variable decelerations (Choice A) are abrupt, unpredictable decreases in the fetal heart rate, usually associated with cord compression. Early decelerations (Choice C) are usually benign and mirror the contraction pattern. Accelerations (Choice D) are reassuring signs of fetal well-being, characterized by an increase in the fetal heart rate.
4. The clinic nurse teaches a patient with a 42 pack-year history of cigarette smoking about lung disease. Which information will be most important for the nurse to include?
- A. Options for smoking cessation
- B. Reasons for annual sputum cytology testing
- C. Erlotinib (Tarceva) therapy to prevent tumor risk
- D. Computed tomography (CT) screening for lung cancer
Correct answer: A
Rationale: The most critical information for the nurse to provide to a patient with a significant smoking history is options for smoking cessation. Smoking is the primary cause of lung cancer, making smoking cessation essential in reducing the risk of developing the disease. Annual sputum cytology testing is not a standard screening test for lung cancer; instead, CT scanning is being explored for this purpose. Erlotinib therapy is used in lung cancer treatment but not for preventing tumor risk in individuals without cancer. CT screening for lung cancer is still under investigation and is not primarily aimed at prevention but rather early detection in high-risk individuals.
5. Which of the following components is associated with hypertonic dehydration?
- A. Plasma sodium levels above 150 mEq/L
- B. Fluid moves from extracellular space to intracellular space
- C. Water loss is greater than electrolyte loss
- D. Physical signs and symptoms are grossly apparent
Correct answer: C
Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.
