Final answer:
The nurse should inform the client that sildenafil can interact with certain medications, particularly nitrates used for heart conditions, and it should be taken as prescribed by a healthcare provider. It is a common prescription drug for erectile dysfunction that should be used carefully to avoid potential drug interactions and side effects.
Step-by-step explanation:
In response to the student's question regarding sildenafil for the treatment of erectile dysfunction (ED), the correct statement that the nurse should make is: Sildenafil can interact with certain medications. Sildenafil, marketed as Viagra®, is a phosphodiesterase-5 (PDE5) inhibitor which is effective in treating approximately 70 to 85 percent of cases of ED. However, it is important to be cautious about drug interactions, particularly in men with cardiac conditions who are on nitrates, as this combination can lead to severe hypotension and is potentially life-threatening. Sildenafil is a first-line treatment for ED, but it should be taken as prescribed by a doctor, and patients should be aware of possible side effects and interactions with other substances such as alcohol.
It is a misconception that sildenafil is not recommended for ED; in fact, it's one of the most commonly used drugs for this condition. While it can be taken daily, it's typically recommended to take sildenafil only before sexual activity, and not more than once in a 24-hour period. Moreover, while moderate alcohol consumption may not lead to severe interactions, heavy drinking is generally discouraged as it can increase the chances of side effects and further impact erectile function.
