Final Answer:
The nurse should include the following instructions for testicular self-exam: B. Roll each testicle between the thumb and fingers, and C. Perform testicular self-examination before a warm bath or shower.
Step-by-step explanation:
The correct instructions for a testicular self-exam involve gently rolling each testicle between the thumb and fingers to detect any abnormalities. This method allows the person to feel for any lumps or changes in texture. Additionally, performing the self-examination before a warm bath or shower is recommended because the warmth helps relax the scrotum, making it easier to detect any abnormalities.
Comparing both testicles simultaneously (option A) may not be effective, as it could lead to missing subtle differences between the two. The emphasis should be on examining each testicle individually. Performing the self-examination every 2 weeks (option D) is not necessary; a monthly frequency is generally recommended. Providing clear and accurate instructions ensures that the individual can perform the self-exam correctly and increases the chances of early detection of any potential issues.
