Stage 1 — Recognize cues. The emergency department nurse completes the initial assessment. Highlight the findings that require immediate follow-up.

Quick answer
Select BP 82/48 (MAP 59), mottled knees with capillary refill 4 seconds, 15 mL of urine in 2 hours, and inability to name the month or hospital.

Why this is correct
These four findings show organ hypoperfusion: arterial pressure below the MAP 65 target, peripheral mottling with slow refill despite warm central skin, kidney hypoperfusion with urine output far below 0.5 mL/kg/hr, and acute encephalopathy in a client who was working and self-managing medications 2 days earlier. Together they move the picture from urinary infection to possible septic shock.

Easy analogy or mental picture
The infection findings tell you where the fire started; the perfusion findings tell you the house is already losing power in several rooms.

Memory hook
Source cues say where; perfusion cues say how bad. Act first on how bad.

NCLEX decision rule
In suspected infection, prioritize findings of organ dysfunction and hypoperfusion (MAP, mentation, urine output, skin perfusion) over findings that only localize the source.

Why the other choices are wrong
Dysuria with frequency and vomiting are tempting because they are clearly abnormal, but they describe the urinary source and would be expected even in uncomplicated pyelonephritis. Clear lungs and a soft abdomen with active bowel sounds matter because they argue against pneumonia or an intra-abdominal source, but they are reassuring, not findings to act on. Glucose 186 mg/dL is common stress hyperglycemia in a client with diabetes and does not explain the shock. Foot numbness since 2019 is chronic neuropathy documented before this illness.
