A nurse is reviewing the laboratory values of a patient receiving total parenteral nutrition (TPN). The glucose is 72 mg/dL, chloride is 100 mEq/L, sodium is 138 mEq/L, and potassium is 3.0 mEq/L. What action should the nurse plan to take?
Administer glucagon IM.
Discontinue the TPN infusion.
Request a potassium replacement.
Check the patient for a positive Chvostek’s sign.
The Correct Answer is C
The correct answer is Choice C.
Step 1 is to interpret the laboratory values. The glucose level is within the normal range (7099 mg/dL). The chloride level is within the normal range (97-107 mEq/L). The sodium level is within the normal range (135-145 mEq/L). However, the potassium level is low (normal range is 3.5-5.0 mEq/L)89101112.
Step 2 is to plan the action based on the interpretation. Given the low potassium level, the nurse should plan to request a potassium replacement

Choice D rationale
Moist skin is not typically a symptom of dehydration. In fact, one of the symptoms of severe dehydration can be dry, cool skin.
Correct Answer is C
Explanation
Choice A rationale
Hyperactive reflexes are not typically associated with hypokalemia. Hypokalemia, or low potassium levels in the blood, can cause muscle weakness, fatigue, constipation, and arrhythmia.
Choice B rationale
Extreme thirst is not a typical symptom of hypokalemia. It is more commonly associated with conditions such as diabetes.
Choice C rationale
A weak, irregular pulse is a common symptom of hypokalemia. Low levels of potassium can affect heart function, leading to abnormal heart rhythms.
Choice D rationale
Hyperactive bowel sounds are not typically associated with hypokalemia. In fact, constipation is a common symptom of this condition.
