Final answer:
The nurse should assess the patient for erectile dysfunction and other male reproductive system conditions, considering risk factors like age, health history, and current symptoms.
Step-by-step explanation:
When a male patient indicates that he thinks he has a sexual dysfunction, the nurse should assess the patient for conditions such as erectile dysfunction (ED), which is characterized by difficulty initiating or maintaining an erection. ED has a high prevalence among aging men, and risk factors include diabetes, vascular disease, psychiatric disorders, prostate disorders, certain medications, and low testosterone levels.
Other conditions the patient may be assessed for include prostate issues like prostatitis or prostate cancer, testicular conditions like testicular cancer, and infections that may affect the urogenital system such as urinary tract infections. It is important for the nurse to take a comprehensive health history to identify any physical or psychological factors that may contribute to the patient's concerns about sexual dysfunction.
