The kidneys are the body’s elite filtration units, working nonstop to remove waste, balance fluids and electrolytes, regulate blood pressure, and support red blood cell production. Each nephron acts like a microscopic lab, filtering blood and adjusting its composition with incredible precision. But when kidney function declines—whether due to diabetes, hypertension, or autoimmune disorders—the body’s internal balance begins to fail.
This section explores how to recognize early signs of kidney impairment, interpret lab markers like eGFR and creatinine, and understand the systemic effects of renal dysfunction. For psychiatric NPs, it’s essential to monitor kidney health when prescribing psychotropic medications, especially lithium or mood stabilizers, as renal compromise can significantly alter drug metabolism and safety.
