Correct Answer: C

Rationale: The correct answer is C because morning administration of prednisone mimics the body's natural corticosteroid secretion pattern. Cortisol, a natural corticosteroid, is typically highest in the morning and decreases throughout the day. By taking prednisone in the morning, the client aligns the drug's peak concentration with the body's natural cortisol levels, optimizing its therapeutic effects. Choice A is incorrect because while taking the drug at the same time daily is important for consistency, it does not specifically address the rationale for morning administration. Choice B is incorrect as the effectiveness of prednisone is not solely dependent on its half-life but also on alignment with the body's natural rhythm. Choice D is also incorrect as prednisone can be taken with food and does not necessarily require an empty stomach for optimal absorption.

Correct Answer: C

Rationale: The correct answer is C: Fluid replacement. In end-stage AIDS with Cryptosporidium infection, the client experiences severe diarrhea leading to dehydration and electrolyte imbalances. Fluid replacement is crucial to prevent hypovolemia and maintain electrolyte balance. Adequate hydration supports renal function, prevents further complications, and aids in the elimination of the infectious agent. Pain management (A) may be needed for discomfort but is not the priority. Antiretroviral therapy (B) is essential for managing HIV but does not directly address the immediate issue of dehydration. High-calorie intake (D) is important for overall nutrition but does not address the urgent need for fluid replacement in this situation.

Correct Answer: A

Rationale: The correct answer is A: White patches on the tonsils. Group A streptococci infection commonly presents with exudative tonsillitis, characterized by the presence of white patches or pus on the tonsils. This is due to the inflammatory response triggered by the bacteria. Hypertrophied tonsils (B), hemorrhage in the tonsils (C), and bleeding in the tonsils (D) are less likely to be visual signs of a streptococcal infection and are more indicative of other conditions or complications. Therefore, white patches on the tonsils are the most specific visual sign associated with group A streptococci tonsillar infection.

Correct Answer: C

Rationale: The correct answer is C: limit daily alcohol intake. This is crucial for clients with cirrhosis as alcohol can exacerbate liver damage. Limiting alcohol intake helps prevent further harm to the liver and promotes overall health. Supplementation with multivitamins (choice A) can be beneficial, but not as essential as avoiding alcohol. Taking sleeping pills (choice B) may worsen liver function and is not recommended. Limiting contact at all times (choice D) is irrelevant to managing cirrhosis.

Correct Answer: A

Rationale: Rationale for Correct Answer (A): Most AIDS patients with multiple opportunistic infections die due to a weakened immune system impairing response to therapy. When the immune system is compromised, the body struggles to fight off infections effectively, even with treatment. This results in the infections becoming more severe and ultimately leading to death. Summary of Other Choices: B: Weakened immune system impairs resistance to infection - While this is true, it doesn’t directly address the cause of death in AIDS patients with multiple infections. C: Infection cannot be treated effectively - This is not entirely accurate as infections can be treated, but the weakened immune system hinders the response to treatment. Overall, Choice A is the most accurate as it directly links the weakened immune system to the inability to respond effectively to therapy, leading to fatal outcomes.
