A college student arrives at the clinic for a physical examination and asks the practical nurse (PN) how he should perform testicular self-examination (TSE). Which information should the PN provide?

A. Examine the testicles during bathing: Performing TSE during a warm shower or bath allows the scrotal skin to relax, making it easier to palpate the testicles and detect any lumps, swelling, or changes in texture, which is the recommended method for accurate self-examination. B. Manipulate the testicles upon rising: While morning may be convenient for some hygiene routines, the scrotum is often tighter when cold, making palpation less effective than during a warm bath or shower. C. Inspect the testicles using a mirror: Visual inspection alone is insufficient because small lumps or irregularities may not be visible. Palpation is essential to detect early abnormalities. D. Compare both testicles concurrently: Comparing both testicles can help identify asymmetry, but the primary step is careful palpation of each testicle individually to detect changes in size, shape, or texture.
