Critical Care Nursing NCLEX Questions

Correct Answer: A

Rationale: The correct answer is A because pain and anxiety trigger the sympathetic nervous system's fight-or-flight response, increasing heart rate, blood pressure, and stress hormones to prepare the body for potential danger. This physiological response helps the individual respond to perceived threats. Choices B, C, and D are incorrect because pain and anxiety typically increase stress levels, do not necessarily remove one from harm, and can hinder rather than enhance performance due to distraction and decreased focus.

Correct Answer: D

Rationale: The correct answer is D. When rewarming a hypothermic patient, the goal is to gradually increase their core temperature. A core temperature of 94�F (34.4�C) is still below the normal range, but it indicates that the rewarming process is working. Shivering (A) is a normal response to rewarming. A decrease in blood pressure (B) may be expected due to peripheral vasodilation during rewarming. Developing atrial fibrillation (C) may be a concern but does not necessarily indicate that rewarming should be discontinued. Therefore, choice D is correct as it signifies progress in the rewarming process.

Correct Answer: C

Rationale: Rationale: - Improved collaboration enhances job satisfaction and reduces burnout, leading to increased staff retention. - Higher staff retention promotes continuity of care, improves team dynamics, and enhances patient outcomes. Summary: - A: Not directly related to collaboration, more about performance evaluation. - B: Manners may improve, but not the most important effect of collaboration. - D: Collaboration involves open communication, so less discussion in front of patients is not a positive outcome.

Correct Answer: D

Rationale: The correct answer is D: Identify the problem. This is the first action the nurse should take in the nursing process as it helps in understanding the client's issue. By identifying the problem, the nurse can gather more information through further assessment to determine the underlying cause of the client's difficulty in walking. This step is crucial for developing an effective care plan and interventions. A: Predict the likelihood of the outcome - This choice is not appropriate as predicting the outcome should come after identifying the problem and implementing interventions. B: Consider alternatives - While considering alternatives is important in the decision-making process, it is not the immediate action needed in this scenario. C: Choose the most successful approach - This choice is premature as the nurse needs to first identify the problem before determining the most successful approach.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): When the low-pressure alarm sounds for a patient with an arterial line, the nurse should assess for cardiac dysrhythmias first. This is because a sudden drop in pressure could indicate a serious issue affecting the heart's ability to pump effectively. Identifying and addressing any cardiac dysrhythmias promptly is crucial for patient safety. Summary of Incorrect Choices: A: Fast flush of the arterial line - This would not address the underlying cause of the low-pressure alarm and may not be necessary. B: Check the left hand for pallor - While assessing perfusion is important, it is not the priority when the alarm indicates a potential cardiac issue. D: Rezero the monitoring equipment - While important for accuracy, it is not the priority when the alarm indicates a potential cardiac concern.
