Diagnostic test monitoring
Expect items requiring normal-range recognition: CBC (Hgb, WBC, platelets), BMP (sodium 135–145, potassium 3.5–5.0, BUN, creatinine, glucose), INR (target 2–3 for most warfarin indications), and ABG basics. The PN reports critical values promptly to the RN/provider.
Pitfall: Candidates pick the value closest to normal rather than the most clinically significant abnormality — NCSBN wants the result that drives action.
