Introduction
Scenario setup A neonate 10 days old has T 38.2°C rectal, feeding poorly, lethargic. HR 190, RR 66. Fever in young infant is a high-risk infection scenario. RN priorities: urgent evaluation, sepsis workup themes, monitoring, IV access, antibiotics per order—not “viral illness reassurance only.” RN traps: routine discharge home without workup in neonatal fever items. This case-study format is intentional: boards reward trajectory thinking—what changed, what is unstable, and what you do next for the role named in the stem. For NCLEX-RN (United States), read the assignment line before you eliminate answers. Slow read: re-scan the stem for vitals trends, oxygen settings, allergies, and time since onset—case items often hide the decisive clue in a single line. 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.
