A nurse is reinforcing teaching about testicular self-examination with a young adult client. Which of the following instructions should the nurse include?

A. Perform the examination just after a warm bath or shower: Warmth from bathing relaxes the scrotal muscles, allowing the testes to hang lower and making lumps or changes easier to feel. This improves accuracy and comfort during self-examination, supporting early detection of abnormalities. B. Complete the examination once per week: Monthly self-examination is recommended because weekly exams can lead to unnecessary anxiety and make it harder to notice true changes. Monthly checks provide a consistent interval to detect new lumps or swelling. C. Squeeze each testicle between the thumb and forefinger: Testicular self-exam involves gently rolling each testicle between the fingers, not squeezing, which can cause pain and injury. The goal is to feel for smoothness, uniformity, and the presence of any firm masses. D. Begin performing testicular self-examination at 30 years of age: Testicular cancer is more common in males ages 15–35, so beginning self-exams earlier supports timely detection. Starting at 30 delays screening during the highest-risk years.
