A nurse is reviewing the laboratory results of a client who has fluid volume deficit. The nurse would expect which of the following findings?

Sodium 155 mEq/L. Choice A rationale:

A urine specific gravity of 1.035 indicates concentrated urine and is consistent with fluid volume deficit. However, it is not the most specific finding for this condition.

Choice B rationale:

A BUN (blood urea nitrogen) level of 19 mg/dL can be a normal value. It is within the reference range (usually around 7-20 mg/dL) and does not provide specific information about fluid volume deficit.

Choice C rationale:

A hematocrit of 44.9% can also be within the normal range for some individuals, and while it can be elevated in cases of fluid volume deficit, it is not as sensitive as other parameters for detecting this condition.

Choice D rationale:
This is the correct answer because a sodium level of 155 mEq/L is elevated and indicates hypernatremia, which is associated with fluid volume deficit. Hypernatremia occurs when there is a relative lack of water in relation to the sodium concentration in the blood, and it can lead to dehydration

The correct answer is choices A, B, and D. Here are the rationales for each choice:

Choice A rationale:

Sweet potatoes are an excellent source of potassium. One medium sweet potato contains about 542 mg of potassium, making it a great option for a high-potassium diet.

Choice B rationale:

Bananas are well-known for their high potassium content. A medium banana provides approximately 451 mg of potassium, which is beneficial for maintaining proper muscle and nerve function.

Choice C rationale:

Grapes are not particularly high in potassium compared to other fruits. They contain some potassium, but not enough to be considered a significant source for a high-potassium diet.

Choice D rationale:

Watermelon is a good source of potassium. Two wedges of watermelon contain about 640 mg of potassium, making it a suitable choice for increasing potassium intake.
