A nurse is planning to teach a client about a high-potassium diet. Which of the following foods should the nurse instruct the client to eat? (Select all that apply.).
Sweet Potatoes.
Bananas.
Grapes.
Watermelon.
Correct Answer : A,B,D
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.

Correct Answer is A
Explanation
The correct answer is choice A. Client has an NG tube to gastric suction.
Choice A rationale:
Having an NG tube to gastric suction can lead to hypokalemia because the suctioning process removes potassium from the stomach contents, leading to a decrease in serum potassium levels.
Choice B rationale:
While a history of alcohol abuse disorder can lead to various electrolyte imbalances, it is not the most direct cause of hypokalemia compared to gastric suction.
Choice C rationale:
Drinking 3.5 to 4 liters of water each day can lead to dilutional hyponatremia but is less likely to cause hypokalemia directly.
Choice D rationale:
Spironolactone is a potassium-sparing diuretic, which means it helps retain potassium in the body. Therefore, it is not a causative factor for hypokalemia.
Correct Answer is B
Explanation
Choice A rationale:
Narcotics are not known to directly cause hypokalemia. Their main effects are related to pain relief and central nervous system depression.
Choice B rationale:
Thiazide diuretics can cause potassium loss in the urine, leading to hypokalemia. These diuretics work by inhibiting sodium reabsorption in the distal convoluted tubule, which can lead to potassium excretion as well.
Choice C rationale:
Corticosteroids can cause sodium and water retention but are not typically associated with significant potassium abnormalities.
Choice D rationale:
Muscle relaxers are not known to cause hypokalemia. They primarily act on the neuromuscular junction and do not directly impact potassium levels.
