What is essential for a nurse to assess before administering potassium IV?

Assessing urine output before administering intravenous potassium is crucial because potassium levels are closely related to kidney function and fluid balance. The kidneys play a significant role in regulating potassium levels in the body, and adequate urine output indicates that the kidneys are functioning properly. If a patient has low urine output, it could signal renal impairment or a risk of hyperkalemia (elevated potassium levels), which can lead to serious cardiac complications.

Monitoring urine output helps ensure that the patient's body can effectively excrete the potassium being administered. This assessment aids in preventing potential complications that could arise from potassium overload, thereby safeguarding the patient's health during treatment.
