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.

Answer and Explanation

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 C

Explanation

PacO2 50 mm Hg. Choice A rationale:

Potassium levels are not directly related to respiratory acidosis. Potassium levels may be affected in certain conditions, but they are not specific indicators of respiratory acidosis.

Choice B rationale:

HCO3- (bicarbonate) levels may be elevated in metabolic alkalosis, not respiratory acidosis. In respiratory acidosis, the primary abnormality is an increased PacO2, not HCO3-.

Choice C rationale:

The partial pressure of carbon dioxide (PacO2) is a key parameter in diagnosing respiratory acidosis. In this case, a PacO2 of 50 mm Hg suggests hypoventilation and an excess of carbon dioxide in the blood, contributing to acidosis.

Choice D rationale:

The pH level given (pH 7.45) is within the normal range, which contradicts the diagnosis of respiratory acidosis. In respiratory acidosis, the pH would be expected to be below the normal range of 7.35-7.45 due to increased carbon dioxide levels.

A. Phosphorus 4.5 mEq/L. B. Potassium 2.9 mEq/L. C. Calcium 8.2 mg/dL. D. Sodium 145 mEq/L.

Correct Answer is B

Explanation

Choice A rationale:

A phosphorus level of 4.5 mEq/L falls within the normal range, which is typically between 2.5 to 4.5 mEq/L. Although it's essential to monitor phosphorus levels, it is not the priority finding in this scenario.

Choice B rationale:

A potassium level of 2.9 mEq/L is the priority finding. The normal range for potassium is typically between 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L indicates severe hypokalemia, which can lead to life-threatening cardiac arrhythmias and muscle weakness. Immediate intervention is necessary to address the potassium imbalance.

Choice C rationale:

A calcium level of 8.2 mg/dL falls within the normal range (typically 8.5 to 10.2 mg/dL). While calcium levels are essential to monitor, they do not take precedence over the critically low potassium level in this situation.

Choice D rationale:

A sodium level of 145 mEq/L falls within the normal range, which is usually around 135 to 145 mEq/L. Although monitoring sodium levels is important, it is not the priority finding when compared to the critically low potassium level.
