What essential information must a nurse gather before administering potassium supplements to an elderly client?

Gathering information about the client's urine output is essential before administering potassium supplements to an elderly client because potassium is primarily excreted by the kidneys. Evaluating urine output helps assess kidney function and the ability to clear excess potassium from the body. If there is inadequate urine output, administering potassium could lead to hyperkalemia, a potentially dangerous condition characterized by elevated potassium levels in the blood, which can cause serious cardiac arrhythmias or other complications.

In the context of geriatric care, where elderly clients may have diminished renal function or other comorbidities affecting kidney health, monitoring urine output becomes particularly critical. This information can help ensure that the potassium supplement is administered safely, minimizing the risk of adverse effects and promoting overall patient safety.
