Question 2

A young gay patient being treated for his third sexually transmitted disease does not see why he should use condoms, because they don't work. The nurse's most appropriate response would be
 
  a. Condoms may not provide 100 protection, but when used correctly and consistently with every act of sexual intercourse they reduce your risk of getting infected with HIV or other sexually transmitted diseases.
  b. You are correct. Condoms don't always work, so your best protection is to limit your number of partners.
  c. Condoms do not provide 100 protection, so you should always discuss with your sexual partners their HIV status or ask if they have any STD.
  d. Condoms do not provide 100 protection, but when used with a spermicide you can be assured of complete protection against HIV and other STDs.

D

Answer to Question 2

A
Risk-reducing sexual activities decrease the risk of contact with HIV through the use of barriers. The most commonly used barrier is the male condom. Although not 100 effective, when used correctly and consistently, male condoms are very effective in the prevention of HIV transmission.
