The college health clinic nurse is preparing a seminar on testicular self-examination (TSE). Which instruction should be included in the content for this seminar?

A. Inspect the testicles using a mirror. A mirror is not necessary for performing a testicular self-exam. The focus should be on palpation rather than visual inspection alone, as small lumps or irregularities may not be visible but can be felt through careful examination. B. Compare both testicles concurrently. While it is useful to be familiar with the normal size and shape of both testicles, the self-exam should be performed on one testicle at a time. This allows for a more thorough and focused assessment of each testicle for lumps, swelling, or changes in consistency. C. Examine the testicles during bathing. Warm water during a bath or shower helps relax the scrotal skin, making it easier to feel any abnormalities. This is the best time to perform a testicular self-exam, as the testicles hang lower and are more accessible for palpation. D. Manipulate the testicles upon rising. Examining the testicles immediately upon waking is not ideal, as the scrotum may be tighter due to cooler temperatures. This could make it more difficult to detect subtle changes, lumps, or irregularities.
