Correct Answer: B

Rationale: The correct answer is B. Pale mucous membranes, such as those of the eyelids and lips, are a classic sign of anemia in infants. Anemia leads to decreased oxygen-carrying capacity, resulting in tissue hypoxia, which can manifest as pale mucosa. Choice A, a hemoglobin level of 12 g/dL, is within the normal range for a 10-month-old infant and would not necessarily indicate anemia. Choice C, hypoactivity, is a non-specific finding and can be present in various conditions, not specifically anemia. Choice D, a heart rate between 140 to 160, is within the normal range for an infant and is not a specific finding associated with anemia.

Correct Answer: B

Rationale: Administering prescribed IV antibiotics is the most crucial intervention in managing an infected foot ulcer in a client with diabetes mellitus. Antibiotics help combat the infection and prevent its spread systemically, which is vital in diabetic clients to prevent serious complications like sepsis. While obtaining a wound culture (Choice A) may provide valuable information for targeted antibiotic therapy, administering antibiotics promptly takes precedence to prevent the infection from worsening. Elevating the affected foot (Choice C) can help reduce swelling but is not as urgent as administering antibiotics. Consulting the wound care nurse (Choice D) may be beneficial for long-term wound management but does not address the immediate need to control the infection.

Correct Answer: A

Rationale: The correct answer is A: Start an IV infusion of normal saline. The client is showing signs of dehydration, such as abdominal cramping, vomiting, lethargy, and confusion, which can be exacerbated by hyperglycemia. Rehydration is the initial priority to address the fluid imbalance. Option B, obtaining a serum potassium level, though important in the management of diabetes, is not the immediate priority over rehydration. Option C, administering the client's usual dose of insulin, should only be done after addressing the dehydration and confirming the client's blood glucose levels. Option D, assessing the pupillary response to light, is not the most urgent intervention needed in this situation compared to rehydration to correct fluid imbalance.

Correct Answer: C

Rationale: The most crucial nursing assessment in determining whether therapy should be initiated for an asymptomatic HIV-infected client with a CD4 cell count of 500 is the client's willingness to comply with complex drug schedules. Adherence to antiretroviral therapy is essential for its effectiveness. Assessing the client's willingness and ability to comply with the complex medication regimen is crucial to ensure successful treatment and prevent drug resistance. Choices A, B, and D, although important in the overall care of the client, are not as crucial as assessing the client's willingness to adhere to the prescribed drug regimen.

Correct Answer: C

Rationale: Assisting the client to stand by the side of the bed to void is the most appropriate action in this situation. Standing to void often helps relieve the bladder, especially after surgery. Option A, having him drink several glasses of water, may not be as effective as the client might already be adequately hydrated. Option B, Crede maneuver, is a technique for emptying the bladder by applying manual pressure and is not the first-line intervention for a client who cannot void post-surgery. Option D, waiting 2 hours before trying to void again, may delay necessary intervention if the client is experiencing urinary retention.
