When the nurse is obtaining health history during an annual physical examination, the client reports having difficulty with erections for the past 8 months. Which information in the client's history should the nurse consider as a potential reason for erectile dysfunction?

A. A phosphodiesterase inhibitor on the medication list. Phosphodiesterase inhibitors, such as sildenafil (Viagra) and tadalafil (Cialis), are actually used to treat erectile dysfunction rather than cause it. If the client is taking this medication but still experiencing difficulty, it may indicate an underlying medical condition. B. History of type 2 diabetes mellitus. Diabetes is a major risk factor for erectile dysfunction due to its effects on blood vessels and nerve function. Chronic high blood sugar can lead to neuropathy and vascular damage, impairing blood flow to the penis and causing persistent erectile difficulties. C. A lifestyle with minimal physical activity. Sedentary behavior can contribute to conditions like obesity, cardiovascular disease, and poor circulation, which may indirectly affect erectile function. However, it is not as strong a direct cause as diabetes or other medical conditions. D. Works more than 12 hours in a day. Long work hours can lead to stress and fatigue, which may temporarily affect libido and performance. However, work schedule alone is not a primary physiological cause of erectile dysfunction compared to diabetes-related nerve and blood vessel damage.
