IV Therapy and Infusion Safety: Patient Teaching And Safety Netting belongs to the Pharmacological and Parenteral Therapies blueprint domain because the nurse must connect vascular access delivers therapy rapidly but creates risks of infiltration, infection, incompatibility, and dosing error to immediate bedside decisions. On Canadian NCLEX-RN, this content is tested through cue recognition, safety prioritization, and choosing the nursing action that prevents infiltration, extravasation, phlebitis, CLABSI, fluid overload, and medication error. On the exam, writers often pair stable-sounding options with unstable data—notice the mismatch before you commit. If the stem names a license or role, reread that line; scope errors are classic trap answers even when the clinical topic is familiar. Run a 60-second scan: breathing work and oxygenation, perfusion and end organs, neuro baseline, likely infection sources, and devices that can fail quietly. When two answers feel partly right, pick the one that reduces imminent harm and matches orders for the role you were given. Train yourself to state the primary risk in one short phrase before you read the options so distractors do not rewrite your priority list.
