Question 1 of 5
A 73-year-old male patient is in the clinic for a yearly physical and is asking for a prescription for sildenafil. He has listed on his health history that he is taking a nitrate for angina. The nurse is aware that which problem may occur if sildenafil is taken with a nitrate?
Correct Answer: D
Rationale: The correct answer is D: Significant decrease in blood pressure. Sildenafil is a phosphodiesterase type 5 inhibitor used to treat erectile dysfunction, while nitrates are vasodilators commonly used for angina. When taken together, they can cause a dangerous drop in blood pressure due to additive vasodilatory effects. This can lead to hypotension, dizziness, and even syncope. It is crucial to avoid combining sildenafil with nitrates to prevent this potentially life-threatening interaction.
Incorrect
Choices:
A: Reduced effectiveness of the sildenafil - This is incorrect because the issue is not about the effectiveness of sildenafil but rather the dangerous interaction with nitrates.
B: Significant increase in pulse rate - This is incorrect as the concern is more related to blood pressure rather than pulse rate.
C: Increased risk of bleeding - This is incorrect as the interaction between sildenafil and nitrates does not typically increase the risk of bleeding.
