A nurse is reviewing the laboratory results of a client who takes furosemide. Which of the following results should the nurse identify as the priority finding?
Phosphorus 4.5 mEq/L.
Potassium 2.9 mEq/L.
Calcium 8.2 mg/dL.
Sodium 145 mEq/L.
The Correct Answer is B
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.

Correct Answer is B
Explanation
Respiratory acidosis.
Choice A rationale:
Metabolic alkalosis occurs when there is an increase in pH and bicarbonate (HCO₃⁻) levels, which is not the case here. The pH value in this scenario is 7.22, indicating acidosis.
Choice B rationale:
Respiratory acidosis results from the retention of carbon dioxide (PaCO₂) in the blood, leading to a decrease in pH. In this case, the pH is low (7.22), and the PacO₂ is elevated (68 mm Hg), supporting the diagnosis of respiratory acidosis.
Choice C rationale:
Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels, along with a possible negative base excess. However, in this scenario, the base excess is -2, which does not indicate metabolic acidosis.
Choice D rationale:
Respiratory alkalosis occurs when there is a decrease in PaCO₂, leading to an increase in blood pH. The ABG values provided (pH 7.22, PacO₂ 68 mm Hg) are not consistent with respiratory alkalosis.
Correct Answer is ["A","B","D"]
Explanation
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.
