Question 1 of 5
A nurse in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?
Correct Answer: C
Rationale: The correct answer is C: Isosorbide. Isosorbide is a contraindication to taking sildenafil because both medications can cause a significant drop in blood pressure, leading to a serious condition called hypotension. This combination can be life-threatening. Metronidazole, phenytoin, and prednisone do not have significant interactions with sildenafil. Metronidazole is an antibiotic, phenytoin is an antiepileptic, and prednisone is a corticosteroid.
Therefore, the nurse should be cautious when considering prescribing sildenafil to a client already taking isosorbide to avoid complications.
