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 C
Explanation
Choice A rationale:
While acute renal failure can affect phosphorus levels, potassium is the electrolyte most commonly affected in this condition. Kidneys play a crucial role in regulating potassium levels in the body, and when they fail, potassium levels can become dangerously elevated.
Choice B rationale:
Acute renal failure can lead to alterations in magnesium levels, but potassium is typically more affected. Magnesium imbalances may occur but are not the primary concern in this condition.
Choice C rationale:
As mentioned earlier, potassium imbalances are common in acute renal failure. The nurse should closely monitor the patient's potassium levels and be prepared to intervene if they become too high or too low.
Choice D rationale:
Calcium levels may also be affected in acute renal failure, but potassium remains the most critical electrolyte to monitor in this condition.
Correct Answer is ["A","D"]
Explanation
The correct answer is A. Limit intake of canned soups and D. Read labels on foods before eating.
Choice A rationale:
Canned soups often contain high levels of sodium, which can contribute to exceeding the recommended daily sodium intake. Limiting these can help manage sodium levels effectively.
Choice B rationale:
Choosing diet sodas over bottled water is not advisable. Diet sodas can still contain sodium and other additives that are not beneficial for a low-sodium diet. Bottled water is a better choice as it typically contains no sodium.
Choice C rationale:
Bottled salad dressings often contain high amounts of sodium. Opting for homemade or low-sodium versions is a better strategy for maintaining a low-sodium diet.
Choice D rationale:
Reading labels on foods before eating is crucial for identifying hidden sources of sodium and making informed dietary choices. This practice helps in adhering to a low-sodium diet by avoiding foods with high sodium content.
