REx-PN
Diuretics remove sodium and water. That can relieve edema, pulmonary congestion, and hypertension, but excessive volume removal can lower venous return and blood pressure. When a client stands, gravity shifts blood into the legs; a volume-depleted client may not compensate quickly enough to maintain cerebral perfusion. The result may be light-headedness, blurred vision, weakness, or a fall. Safe nursing care connects the symptom with the medication, recent dose, blood-pressure trend, daily weight, urine output, renal function, and electrolytes. The immediate goal is to prevent injury and identify deterioration—not to independently discontinue or change the prescription.
