What should the nurse address first when talking to a male client about starting a prescription for sildenafil?

When discussing a new prescription for sildenafil with a male client, it is essential to first inquire about the medications they are currently taking, including over-the-counter products. This is critical because sildenafil can interact with certain medications, particularly nitrates used for chest pain, which can lead to serious side effects such as hypotension. Understanding the patient's current medication regimen allows the nurse to assess the safety of starting sildenafil and to provide informed recommendations or precautions.

While discussing the benefits, potential side effects, and the client's medical history are important aspects of patient education and assessment, identifying existing medications is the primary concern that ensures the safety and well-being of the client before proceeding with treatment. This step sets the foundation for any further discussions about the medication.
