Trap · weight unit · patient PT005

Weight in lb read as kg

Clearance is inflated 2.2 times, so the patient keeps a full-function dose their kidneys can't clear.

The patient's rows

Exactly what the agent sees for PT005, copied from the chart. The value this mistake misreads is underlined.

Two readings of the same rows

Every step is shown. Where the careless reading goes wrong, the value is underlined.

What a careless agent computes

Reads 176 lb as 176 kg, skipping the × 0.4536 the unit column asks for.

Weight: 176 read as kg → 176 kg (the value this mistake misreads)
Creatinine: 1.6 mg/dL (2026-10-31T06:12) read as mg/dL → 1.60 mg/dL
CrCl: (140 − 72) × 176 ÷ (72 × 1.60) = 103.9 mL/min (the value this mistake misreads)

Order	Daily dose	Limit	Flagged
RX6102Bremazotan	300 × 1 = 300 mg	400 mgCrCl ≥ 50 (the value this mistake misreads)	no (the value this mistake misreads)

Output line: {"crcl_ml_min":103.9,"flagged_order_ids":[]}

The correct answer

Reads the unit, status, frequency and time columns as the instruction says, and flags only a daily dose strictly over the band's limit.

Weight: 176 read as lb → 79.8 kg
Creatinine: 1.6 mg/dL (2026-10-31T06:12) read as mg/dL → 1.60 mg/dL
CrCl: (140 − 72) × 79.8 ÷ (72 × 1.60) = 47.1 mL/min

Order	Daily dose	Limit	Flagged
RX6102Bremazotan	300 × 1 = 300 mg	200 mgCrCl 25-50	yes

Output line: {"crcl_ml_min":47.1,"flagged_order_ids":["RX6102"]}

The same mistake also changes PT006, PT014, which share this trap family, and fails 4 more of their tests. No patient from another family moves.
