Diuretics

Diuretics matter in REx-PN preparation because they sit at the boundary between routine care and avoidable harm. Diuretics move fluid and electrolytes, so learners must identify whether the patient needs decongestion, blood-pressure control, ICP support, or electrolyte correction while preventing dehydration, renal injury, arrhythmias, and unsafe interactions. For Canadian practical nursing entry-to-practice, the learner must not memorize a list in isolation. The safer pattern is to ask what patient problem is being treated, what physiologic change is expected, what finding would make the treatment unsafe, and which action fits focused assessment, safe administration, patient teaching, documentation, and timely reporting.
