Critical Care Nursing Questions

Correct Answer: A

Rationale: The correct answer is A: Absence of cerebral blood flow. Brain death is determined by the irreversible cessation of all brain functions, including blood flow to the brain. When there is no cerebral blood flow, the brain is unable to function, leading to brain death. This criterion is essential in diagnosing brain death as it indicates a complete loss of brain function. Explanation for why the other choices are incorrect: - B: Absence of brainstem reflexes on neurological examination is a common sign of brain death, but it is not the primary criterion. - C: Presence of Cheyne-Stokes respirations is not indicative of brain death. It is a pattern of breathing that can be seen in various conditions, not specifically brain death. - D: Confirmation of a flat electroencephalogram is a supportive test for brain death but not the primary criterion. The absence of brain activity on an EEG can help confirm brain death but is not as definitive as the absence of cerebral blood flow.

Correct Answer: D

Rationale: The correct answer is D because the vision of the American Association of Critical-Care Nurses focuses on creating respectful, healing, and humane environments. This aligns with the core values of nursing, emphasizing compassion, dignity, and patient-centered care. A is incorrect as the focus is not solely on the work environment. B is incorrect as it emphasizes the role of physicians over the collaborative approach advocated by the AACN. C is incorrect as it only addresses meeting patient needs, whereas the vision encompasses a broader scope of creating healing environments.

Correct Answer: A

Rationale: The correct answer is A because it promotes patient-centered care by involving the patient and family in decision-making, respecting their autonomy and preferences. This approach acknowledges the importance of cultural beliefs and values in end-of-life care. Choice B undermines patient autonomy by bypassing direct communication with the patient. Choice C assumes all Filipino individuals have the same cultural needs, which is not accurate. Choice D generalizes preferences without considering individual patient needs and wishes. Overall, choice A is the most appropriate as it aligns with the principles of patient-centered care and cultural competence.

Correct Answer: B

Rationale: The correct answer is B: Explaining all procedures in easy-to-understand terms. This intervention is appropriate as it helps reduce the patient's anxiety by providing clear information about what to expect during their stay in the critical care unit. This promotes a sense of control and understanding, which can positively impact the patient's coping mechanisms. A: Allowing unrestricted visiting by several family members at one time may overwhelm the patient and interfere with their rest and recovery. C: Providing back massage and mouth care may be beneficial but may not directly address the patient's need for information and understanding. D: Turning down the alarm volume on the cardiac monitor may provide a more comfortable environment but does not address the patient's emotional and psychological needs related to coping with admission to the critical care unit.

Correct Answer: A

Rationale: The correct answer is A. The nurse should suggest that the father contact his spiritual leader for counseling. This option is appropriate as it recognizes the importance of spirituality in coping with difficult situations. It offers emotional support and guidance to the father and his son during a time of crisis. Option B is incorrect as the nurse sharing her own religious beliefs may not align with the father's beliefs, potentially causing confusion or discomfort. Option C is not the best intervention, as the doctor's role is primarily medical, and explaining the odds of survival may not address the emotional and spiritual needs of the family. Option D is also incorrect as leaving the father and son to grieve alone does not provide them with the necessary support and guidance during such a challenging time.
