Correct answer: D — Clarify dosing directions for safe labelling and clinical check

Insulin is high risk, and clear dosing directions support safe use and clinical checking. 'Use as directed' may be insufficient where the dose is known or can be clarified, particularly if there is a discrepancy. Supplies should include appropriate counselling and necessary administration equipment if prescribed or locally supplied. Estimating doses is unsafe.
