Key Concepts
Introduction
PN scope You observe, measure, document trends, administer fluids/electrolyte replacements per order, and escalate when symptoms or vitals worsen. You do not independently prescribe replacement rates or interpret ABGs beyond reporting values unless the stem defines extended scope. Traps: routine tasks during muscle weakness + arrhythmia suspicion, giving potassium PO/IV without confirming renal status / order / route when the stem flags risk, or ignoring post-thyroid tingling after surgery. For NCLEX-PN (United States), questions rarely announce the topic in the first sentence. They hide it inside vitals, labs, and a short story. Your job is to name the clinical problem, justify why it matters now, and select the safest next step for the role you are givenโbefore you let distractors pull you toward busywork or out-of-scope heroics. When two answers feel partly right, pick the one that closes risk first and matches your license in the stem. On the exam, writers often pair stable-sounding options with unstable dataโnotice the mismatch before you commit. If the stem names a license or role, reread that line; scope errors are classic trap answers...
