Which of the following pairings is correct?

• A. Oral (pills) - paracetamol
• B. Intravenous - albuterol inhaler
• C. Subcutaneous - saline
• D. Inhalation - insulin

Answer: (A)

Think about how drugs are typically given and in what form. Paracetamol is almost always taken by mouth as a tablet, so pairing it with oral pills fits standard practice. Albuterol inhaler is designed for inhalation, not intravenous administration, so the intravenous pairing isn’t correct. Saline is a diluent or fluid for infusion and isn’t normally used as a subcutaneous drug, so that match isn’t standard. Insulin is classically given by subcutaneous injection, and while there is inhaled insulin, it isn’t the conventional method taught for insulin. In everyday practice, the oral pills pairing with paracetamol aligns with how the medication is most commonly administered.
