A high school student tells the school nurse that during biology the class learned that alcohol is associated with erectile dysfunction.The student wonders why so many girls get pregnant during evenings when alcohol is consumed.The nurse plans a response based upon which concept?

A) Alcohol is a central nervous system depressant which affects judgment.
B) Erectile dysfunction only occurs after years of alcohol abuse.
C) Alcohol is a sexual stimulant.
D) Erectile dysfunction occurs only in men older than 50.

Alcohol is a central nervous system depressant which affects judgment, leading to impaired decision-making and increased risk-taking behavior, including unprotected sex which can result in unintended pregnancies. The student's understanding of the link between alcohol and erectile dysfunction may not be entirely accurate, but the nurse's response should address the underlying issue of alcohol's effect on behavior and decision-making. Option B is incorrect as erectile dysfunction can occur even after occasional alcohol consumption. Option C is also incorrect as alcohol is known to impair sexual function. Finally, Option D is incorrect as erectile dysfunction can occur in younger men as well.
