Choice A rationale:
Weight gain is the most objective and reliable indicator of improved nutritional status in patients with HIV-II and wasting syndrome. It directly reflects an increase in lean body mass, which is essential for restoring physical strength, immune function, and overall health.
A weight gain of 2 lb (1 kg) in a month is considered a clinically significant improvement for this patient population. It demonstrates that the patient is consuming more calories than they are expending, leading to a positive energy balance and tissue growth.
Other assessment findings, such as food intake, food choices, and oral discomfort, can be subjective and influenced by various factors, such as appetite, taste changes, nausea, fatigue, and psychosocial issues. While they provide valuable information about the patient's nutritional status, they do not directly measure the actual improvement in body composition.
Choice B rationale:
Consuming 90% of meals and snacks is a positive sign that the patient is adhering to their dietary recommendations. However, it does not guarantee that they are consuming enough calories to promote weight gain. The patient's individual energy needs and the nutritional content of the meals and snacks must be considered.
Choice C rationale:
Choosing high-protein foods is important for building and repairing tissues, but it does not ensure adequate overall caloric intake. The patient may still be experiencing a calorie deficit if they are not consuming enough total calories, even if they are focusing on protein-rich foods.
Choice D rationale:
Decreased oral discomfort can facilitate better food intake, but it does not directly reflect weight gain or improved nutritional status. The patient may still have challenges with appetite, nausea, or other factors that hinder their ability to consume enough calories.

Rationale:

Step 1: Divide the total volume of fluid (2000 ml) by the total time in hours (24 hours). Step 2: Perform the calculation: 2000 ml ÷ 24 hours = 83.33 ml/hour.

Step 3: Round the answer to the nearest whole number, as fluid administration is typically measured in whole milliliters.

The correct answer is 83 ml/hour.
