Genitourinary System ( 5 Questions)
A nurse is providing education to a client who is 65 years old and has erectile dysfunction. The client asks about the use of sildenafil (Viagra).
Which of the following statements should the nurse make?
This is wrong because sildenafil is not a medication that can be taken as needed before sexual activity. It should be taken about an hour before sexual activity, and not more than once a day.
Taking it too often or too close to sexual activity can increase the risk of side effects or interactions with other drugs.
This wrong because sildenafil is not contraindicated for people who have a history of heart disease. However, it should be used with caution and under medical supervision, as it can lower blood pressure and interact with some medications that are used to treat heart conditions, such as nitrates and riociguat.
People who have heart disease should consult their doctor before taking sildenafil and follow their instructions carefully.
“You may experience flushing, headache and nasal congestion as side effects.” Sildenafil (Viagra) is a medication that belongs to a group of drugs called phosphodiesterase 5 (PDE5) inhibitors. It works by relaxing the muscles and blood vessels in the penis, allowing more blood to flow and causing an erection when sexually stimulated. However, it can also cause some common side effects such as flushing, headache and nasal congestion.
These are usually mild and temporary, but they can be bothersome for some people.
This is wrong because sildenafil does not interact with grapefruit juice or alcohol. However, grapefruit juice and alcohol can affect the absorption and metabolism of sildenafil, which can make it less effective or increase the risk of side effects.
Therefore, it is advisable to limit or avoid grapefruit juice and alcohol while taking sildenafil.
