Correct answer: D — supply sufficient quantity with clear instructions and arrange a second freshly reconstituted bottle if needed

The dispensed medicine must remain suitable throughout the prescribed course. If a reconstituted antibiotic expires before the course ends, the pharmacist should plan supply so the patient receives fresh medicine for the remaining days. The course length should not be shortened by the pharmacy. Extending the product expiry beyond the manufacturer's directions is inappropriate.
