What finding would the nurse correlate with the prescription to administer Potassium chloride 10mEq po x 1 now?

A. Peaked T waves: Peaked T waves on an ECG are indicative of hyperkalemia, meaning serum potassium is elevated. Administering potassium in this situation would worsen the imbalance and could lead to life-threatening cardiac arrhythmias. B. Leg cramps: Leg cramps are a common symptom of hypokalemia, reflecting decreased potassium levels affecting skeletal muscle function. Oral potassium chloride is prescribed to restore potassium balance, alleviate muscle cramps, and prevent complications such as arrhythmias or weakness. C. Diarrhea: Diarrhea can cause potassium loss, but it is a symptom rather than an immediate indicator for potassium administration. The nurse would verify serum potassium levels before supplementing, as excessive potassium in someone with normal levels can be dangerous. D. Muscle twitching: Muscle twitching may be a symptom of both hypo- and hyperkalemia but is less specific than leg cramps for low potassium. The presence of other signs, such as cramps or ECG changes, guides the need for potassium supplementation.
