Correct answer: D — Clarify directions and quantity with the prescriber before supply

Insulin is high risk and prescriptions need clear directions and an appropriate quantity. A single cartridge may be insufficient and could reflect an error. The pharmacist should clarify the intended supply and labelling with the prescriber. Rationing insulin or substituting another insulin could cause serious harm.
