A patient with atrial fibrillation and a serum potassium level of 3.0 mEq/L takes digoxin (Lanoxin), ASA (aspirin), KCL (potassium chloride), and warfarin (Coumadin) daily. The patient reports visual disturbances. The nurse suspects problems with which medication?

The correct answer is choice D. The client who has gastroenteritis and is febrile.

Choice A rationale:

The client with end-stage renal failure scheduled for dialysis would not be at risk for fluid volume deficit because dialysis is a treatment that removes waste, salt, and extra water to prevent them from building up in the body, keeping a safe level of certain chemicals in the blood, and controlling blood pressure.

Choice B rationale:

Being NPO (nothing by mouth) since midnight for endoscopy typically involves a short period of fasting. While it could potentially contribute to a mild fluid volume deficit, it is not as significant as other causes like vomiting or diarrhea, which can lead to more substantial fluid losses.

Choice C rationale:

A client with left-sided heart failure and an elevated BNP level is more likely to experience fluid volume overload rather than a deficit. BNP is released in response to ventricular volume expansion and pressure overload, which are indicative of heart failure, not fluid volume deficit.

Choice D rationale:

The client with gastroenteritis and a fever is at risk for fluid volume deficit due to increased fluid losses from vomiting, diarrhea, and fever-induced perspiration. These symptoms align with the common risk factors for fluid volume deficit, which include vomiting, diarrhea, and sweating.

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.
