The prescription is regular insulin 0.05 units/kg/h IV. Before starting this dose-mode pump, the nurse reconciles the bedside record, prepared bag and programming. Click the editable field responsible for the incorrect calculated delivery rate.

Explanation
A contains pounds entered as kilograms. The correct weight is 80 kg, giving 4 units/h and 4 mL/h.
A. A contains pounds entered as kilograms. The correct weight is 80 kg, giving 4 units/h and 4 mL/h.
Why this is the best choice
Divide 176 lb by 2.2 to obtain 80 kg. The displayed dose and concentration match the prescription and bag. The pump correctly calculates 176 × 0.05 ÷ 1 = 8.8 from its wrong input, so the source error is weight rather than the read-only output.
Clinical picture
The observations are fictional teaching data. Apply the stated context; the selected feature does not by itself replace a complete bedside assessment.
Memory hook
Reconcile input units before accepting an internally consistent pump output.
Decision rule
Reconcile input units before accepting an internally consistent pump output.
Why the other regions do not fit
B correctly represents 100 units/100 mL. C is the prescribed weight-based dose. D matches the recorded bag volume and is not responsible for the rate calculation.
Sources
Weight-based medication safety requires patient weight in metric units; the dose in this item is explicitly prescribed.
Dose-mode pump with a weight-unit discrepancy — Reconcile input units before accepting an internally consistent pump output.
Comparison with context — The calculated rate is arithmetically consistent with the programmed inputs; changing the prescribed dose would conceal the wrong weight.
