Overview
Electrolyte Replacement: Delegation And Scope belongs to the Pharmacological and Parenteral Therapies blueprint domain because the nurse must connect electrolyte shifts change cardiac conduction, neuromuscular function, fluid balance, and neurologic status to immediate bedside decisions. On NCLEX-RN, this content is tested through cue recognition, safety prioritization, and choosing the nursing action that prevents arrhythmias, seizures, respiratory weakness, phlebitis, overcorrection, and cardiac arrest. On the exam, writers often pair stable-sounding options with unstable dataโnotice the mismatch before you commit.
