Answer to Question 1

ANS: C
Patients taking sildenafil should not take nitroglycerin, since the combination can produce a life-threatening drop in blood pressure. Beta blockers, calcium channel blockers, and warfarin are not contraindicated with sildenafil.

Answer to Question 2

ANS: C
Salmeterol is a long-acting bronchodilator that also improves ciliary function. Dornase alfa decreases sputum viscosity, but must be administered daily for life, not as needed. Ibuprofen is used in cystic fibrosis to suppress the inflammatory response that underlies the destruction of lung tissue. Tobramycin is given using a small-volume nebulizer, not a metered-dose inhaler.
