Correct answer: ADo not supply pharmacy sildenafil and refer for medical assessment

Pharmacy sildenafil supply requires screening for contraindications and referral criteria. Nitrate use is a contraindication because the combination can cause severe hypotension, and recent chest pain also warrants medical assessment. Dose reduction does not make the interaction safe.
