Correct Answer: B

Rationale: Hypertension is the most prevalent health problem among black Americans. A blunted nocturnal response is one factor responsible for this problem.

Correct Answer: D

Rationale: Informed consent is required when asking a patient to participate in a research study, as mentioned in choice D. Choices A, B, and C involve routine care measures that do not require specific informed consent. Ordering a liquid diet, providing saline solution for dry nasal passages, or listening to a patient's personal secrets are part of standard care and do not typically necessitate formal consent beyond general consent for treatment.

Correct Answer: C

Rationale: The best use of the budget for the black population in the local community would be blood pressure screening. Hypertension is a prevalent health issue among black Americans, occurring at a higher rate than in the white population. Therefore, focusing on blood pressure screening would help in early detection and management of hypertension within this community. Depression screening and sleep disorder information are not the priority as there is not a higher incidence of these conditions in older black clients. Meal planning could be beneficial for clients with diabetes, but it may not be the most critical focus considering the higher prevalence of hypertension among the black population.

Correct Answer: D

Rationale: The correct answer is D. While marital reconciliation, rekindled relationships with siblings, and satisfaction in the role of grandparent are common phenomena among older adults, it is less common for parents and children to see cohabitation as an ideal situation or first preference. Choices A, B, and C reflect common positive family dynamics experienced by older adults, such as improved relationships with siblings, contentment in the grandparent role, and easing of marital tensions over time. On the other hand, choice D stands out as atypical as it suggests an unconventional living arrangement where adult children live with their parent, which is less commonly preferred by older adults.

Correct Answer: A

Rationale: The best action for nurses to take when accepting telephone orders from physicians to minimize liability is to ask the physician to follow up with a faxed, written order and ensure it is signed within 24 hours. This approach helps ensure clarity, accuracy, and documentation of the physician's orders, reducing the risk of misinterpretation or errors. Choices B, C, and D are incorrect. Communicating a diagnosis is outside the nurse's scope of practice and should be done by the physician. Involving another staff member to audiotape the conversation can introduce legal and practical issues. Accepting only written or orally communicated orders in person may not always be practical or feasible in urgent situations where telephone orders are necessary.
