A nurse is reviewing the laboratory results of a client who is taking a loop diuretic and notes the client's potassium level is 3.0 mEq/L. Which of the following physiological responses should the nurse expect related to the client's hypokalemia?

Choice A rationale:

The nurse should prioritize collecting data from a client who reports unilateral calf pain when ambulating. This symptom could indicate the presence of a deep vein thrombosis (DVT), a potentially life-threatening condition. DVT occurs when a blood clot forms in a deep vein, often in the lower extremities. If left untreated, the clot can dislodge and travel to the lungs, causing a pulmonary embolism. Immediate assessment is crucial to rule out DVT and provide appropriate interventions. The nurse should assess the client's calf for swelling, redness, warmth, and tenderness and may also order diagnostic tests like a duplex ultrasound.

Choice B rationale:

Taking a telephone prescription for a client being transferred from the PACU is important but not the top priority in this situation. While timely transfer and adequate post-operative care are essential, addressing a client with unilateral calf pain and the potential for a DVT takes precedence due to the risk of a life-threatening complication.

Choice C rationale:

Reassuring the partner of a client who sustained a closed head injury is a compassionate action but should not be the first priority. The partner's emotional support can be provided once the immediate medical concerns have been addressed.

Choice D rationale:

Reinforcing a client's dressing on an above-the-knee amputation surgical site is important for the client's post-operative care, but it is not the highest priority when compared to the possibility of a DVT. The nurse should address the client's calf pain first and then attend to the dressing reinforcement.

Choice A rationale:
Chloride 99 mEq/L. Rationale: A chloride level of 99 mEq/L is within the normal range, which is typically around 96-106 mEq/L. There is no need to report this value to the provider as it is not indicative of a significant abnormality.
Choice C rationale:
Magnesium 1.9 mg/dL. Rationale: A magnesium level of 1.9 mg/dL is within the normal range, which is generally about 1.5-2.5 mg/dL. This value is not indicative of a significant abnormality and does not require immediate reporting to the provider.
Choice D rationale:
Potassium 3.6 mEq/L. Rationale: A potassium level of 3.6 mEq/L is within the normal range, which is typically around 3.5-5.0 mEq/L. While it's on the lower side of the normal range, it is not low enough to warrant immediate reporting to the provider. However, the nurse should continue to monitor the client's potassium levels and address any potential issues if they persist or worsen.
Choice B rationale:
Sodium 126 mEq/L. Rationale: A sodium level of 126 mEq/L is below the normal range, which is typically around 135-145 mEq/L. Hyponatremia, or low sodium levels, can be a serious condition that can lead to neurological symptoms and other complications. Therefore, the nurse should promptly report this finding to the provider so that appropriate interventions can be initiated.
