Prioritize pre-antibiotic blood cultures first to avoid suppressing growth and to enable timely therapy—collect from two sites with proper antisepsis and volume. Next, obtain the STAT potassium, which can reflect life-threatening dyskalemia and needs rapid handling to avoid hemolysis. Then perform the precisely timed 15:30 cortisol (diurnal assay with defined reference intervals). Finally, complete the routine pre-employment panel. Thus, Option B—1 → 2 → 3 → 4—balances antimicrobial stewardship, emergent electrolyte management, and exact timing. If unit distances threaten the 15:30 cortisol window after completing 1 and 2, call for assistance or notify the clinic to adjust within protocol. Document exact times, follow order of draw (cultures first), and minimize preanalytical errors (tourniquet <1 minute, gentle inversions). Demonstrating a structured, patient-safety–driven triage approach is a key competency for certification and daily practice.
