Critical Care Nursing Exam Questions

Correct Answer: A

Rationale: Step 1: Asking the patient whether he or she wants to get out of bed allows the patient to make a decision regarding their immediate environment, promoting autonomy and control. Step 2: This intervention respects the patient's preferences and fosters a sense of dignity and empowerment, reducing stress. Step 3: Best practice principles in nursing emphasize patient-centered care and promoting patient autonomy. Summary: Choice A is correct as it directly involves the patient in decision-making, enhancing their sense of control. Choices B, C, and D do not provide the same level of autonomy and control to the patient, making them less effective in reducing stress and promoting patient well-being.

Correct Answer: D

Rationale: The correct answer is D, the 70-year-old mother with blood type A positive. This choice is the best candidate for evaluation due to her blood type matching the patient's (A positive) for kidney transplantation. Age and medical history are also crucial factors in determining suitability. The 65-year-old brother (choice A) has hypertension, a significant risk factor. The 35-year-old female (choice B) with food allergies may have potential complications. The 14-year-old son (choice C) is underage and might not be a suitable donor due to age and the potential impact on his growth and development. In summary, choice D aligns with the matching blood type and age, making the mother the most suitable candidate for evaluation.

Correct Answer: A

Rationale: The correct answer is A: Communication of uniform messages from all healthcare team members. This intervention is crucial to ensure consistency in information provided to patients and families, reducing confusion and enhancing trust. When all team members convey the same messages, it helps in clarifying options and facilitating decision-making. Choices B and C are incorrect as they focus on care planning and continuity, which are important but not specifically related to facilitating communication in end-of-life care decisions. Choice D is incorrect as it suggests limiting time for families to express feelings, which can hinder effective communication and support during such a sensitive time.

Correct Answer: A

Rationale: The correct answer is A because writing DNR orders before discontinuation of life-sustaining treatments ensures clear communication and legal documentation of the patient's wishes. Choice B is incorrect as family support is essential in end-of-life care. Choice C is incorrect as DNR orders should be established before withdrawing treatment. Choice D is incorrect as the DNR order should be in place before shift change for immediate implementation if needed.

Correct Answer: A

Rationale: The correct answer is A because nociceptors are specialized nerve receptors that do not adapt much to continual pain response. This lack of adaptation allows nociceptors to continuously signal the presence of tissue-damaging stimuli, which is crucial for the perception of pain. Choices B, C, and D are incorrect because nociceptors do not inhibit the infiltration of neutrophils and eosinophils (B), they do play a role in the inflammatory response (C), and they transmit various types of stimuli including thermal, mechanical, and chemical, not just thermal stimuli (D).
