Question 1 of 5
A nurse is collecting data from a client who takes several daily medications and states that he wants to ask the provider for a prescription for sildenafil (Viagra). The nurse knows that sildenafil is contraindicated due to an interaction with which of the following client's medications?
Correct Answer: B
Rationale: The correct answer is B: Isosorbide. Sildenafil and Isosorbide both cause vasodilation, which can lead to a significant drop in blood pressure if taken together, potentially causing a life-threatening condition known as hypotension. This interaction is known as a pharmacodynamic interaction. Naproxen (
A), Metformin (
C), and Cefuroxime (
D) do not have significant interactions with sildenafil in terms of blood pressure regulation.
