A nurse is assessing a client who has hypokalemia and a new prescription for potassium chloride. Which of the following findings should the nurse report to the provider?

Potassium chloride is an electrolyte replenisher used to resolve hypokalemia, a state where serum potassium levels fall below 3.5 mEq/L. Potassium is essential for maintaining the resting membrane potential of excitable tissues. Correcting deficits requires precise dosing, as overcorrection leads to hyperkalemia, causing lethal cardiac conduction abnormalities and potential asystole. Rationale: A. A capillary refill time of less than 2 seconds is a normal clinical finding indicating adequate peripheral perfusion and cardiac output. This result suggests that the client’s circulatory status is currently stable and does not indicate an adverse reaction to the potassium chloride therapy. Therefore, the nurse does not need to report this specific finding to the healthcare provider. B. Peaked T-waves are a classic electrocardiographic sign of hyperkalemia, indicating that the potassium replacement therapy may have overcorrected the initial deficit. High serum potassium levels accelerate repolarization, which can quickly transition into dangerous arrhythmias like ventricular fibrillation. This is a critical safety finding that requires immediate notification to the provider to prevent cardiac arrest and adjust the medication. C. Constipation is a common symptom associated with the initial state of hypokalemia due to decreased smooth muscle motility in the gastrointestinal tract. While the nurse should monitor bowel function, a report of constipation is expected with the underlying diagnosis and is not a priority for reporting. Effective potassium replacement should eventually help restore normal peristalsis and resolve this specific symptom. D. A blood pressure of 96/80 mm Hg is slightly low but is not the most urgent finding when evaluating the safety of potassium chloride administration. While the nurse should monitor hemodynamics, the immediate threat posed by potassium imbalances is related to cardiac rhythm rather than modest blood pressure fluctuations. Peaked T-waves represent a more direct and fatal complication of electrolyte mismanagement.
