A nurse is assessing a client who is in the second trimester of pregnancy and has a BMI within the expected reference range. Which of the following assessment findings indicates that the client will gain weight within the expected reference range?

Choice A reason: Changing the feeding to a continuous infusion may not improve the constipation, as it does not address the fluid deficit or the fiber content of the formula. Continuous infusion may also increase the risk of aspiration, diarrhea, and bacterial contamination.

Choice B reason: Increasing the amount of free water can help prevent or treat constipation by hydrating the stool and facilitating its passage. The client's fluid intake and output indicate a fluid deficit, which can contribute to constipation. The recommended fluid intake for adults is 30 to 35 mL/kg/day.

Choice C reason: Decreasing the infusion rate of feeding may worsen the constipation, as it reduces the caloric and fluid intake of the client. The infusion rate should be based on the client's nutritional needs and tolerance.

Choice D reason: Requesting a prescription for a diuretic is not appropriate, as it would further dehydrate the client and aggravate the constipation. Diuretics are indicated for clients with fluid overload, not fluid deficit.

Choice D reason: A calorie reduction of 500 fewer calories per day can result in a weight loss of about 0.45 kg (1 lb) per week, which is a safe and realistic goal for most clients. A pound of fat contains about 3,500 calories, so reducing the daily intake by 500 calories can create a deficit of 3,500 calories per week.

Choice A reason: A weight loss of 0.45 kg (1 lb) per day is too rapid and unhealthy, as it can cause dehydration, electrolyte imbalance, muscle loss, and metabolic slowdown. It can also be unsustainable and lead to weight regain. A calorie reduction of 500 fewer calories per day cannot achieve such a drastic weight loss.

Choice B reason: A weight loss of 0.23 kg (0.5 lb) per day is also too rapid and unhealthy, for the same reasons as choice A. A calorie reduction of 500 fewer calories per day cannot achieve such a drastic weight loss.

Choice C reason: A weight loss of 0.23 kg (0.5 lb) per week is too slow and unlikely, as it would require a calorie reduction of only 250 fewer calories per day. This is not enough to create a significant deficit and stimulate weight loss. A calorie reduction of 500 fewer calories per day can result in a faster weight loss.
