Valid look-alike · weight unit · patient PT007

A genuine 150 kg patient

A rule that big numbers must be pounds halves the weight of exactly the patients actual-weight dosing matters most for.

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

Applies a blanket rule, weights over 140 must be lb, instead of reading the unit column.

Weight: 150 read as lb → 68.0 kg (the value this mistake misreads)
Creatinine: 1.3 mg/dL (2026-10-31T07:37) read as mg/dL → 1.30 mg/dL
CrCl: (140 − 45) × 68.0 ÷ (72 × 1.30) = 69.1 mL/min (the value this mistake misreads)

Order	Daily dose	Limit	Flagged
RX4493Aldrovexin	2500 × 1 = 2500 mg	3000 mgCrCl ≥ 60	no
RX7563Dorvatinex	50 × 1 = 50 mg	60 mgCrCl ≥ 40	no
RX2229Cylvarone	1000 × 1 = 1000 mg	900 mgCrCl 45-90 (the value this mistake misreads)	yes (the value this mistake misreads)

Output line: {"crcl_ml_min":69.1,"flagged_order_ids":["RX2229"]}

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: 150 read as kg → 150 kg
Creatinine: 1.3 mg/dL (2026-10-31T07:37) read as mg/dL → 1.30 mg/dL
CrCl: (140 − 45) × 150 ÷ (72 × 1.30) = 152.2 mL/min

Order	Daily dose	Limit	Flagged
RX4493Aldrovexin	2500 × 1 = 2500 mg	3000 mgCrCl ≥ 60	no
RX7563Dorvatinex	50 × 1 = 50 mg	60 mgCrCl ≥ 40	no
RX2229Cylvarone	1000 × 1 = 1000 mg	1200 mgCrCl ≥ 90	no

Output line: {"crcl_ml_min":152.2,"flagged_order_ids":[]}

No other patient's answer moves under this mistake, so this one failure is the whole signal.
