Pathophysiology
What this means clinically
NP Clinic items test who needs ED today: K+ with ECG changes, anuria, pulmonary edema with missed HD, febrile central line, rhabdomyolysis cues, and ACEI/ARB + spironolactone + NSAID triple whammy hyperkalemia. You adjust renally cleared meds, order labs, and coordinate nephrology—not “increase NSAIDs” in CKD. Connect Renal risk & dialysis access in to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
