Choice A rationale: A deep tissue injury involves intact skin with a purple or maroon localized area of discolored, non-blanchable, deep red or maroon, or a blood-filled blister due to damage of underlying soft tissue from pressure or shear. It is a stage that is more appropriate for the described wound involving the epidermis and dermis.
Choice B rationale: Stage III pressure ulcers involve full-thickness tissue loss, but they do not involve the epidermis and dermis.
Choice C rationale: Unstageable ulcers are covered with slough or eschar, making it difficult to determine the depth of tissue involvement. In this case, the wound's description indicates involvement of the epidermis and dermis.
Choice D rationale: Stage IV pressure ulcers involve full-thickness tissue loss with exposed bone, tendon, or muscle, not just the epidermis and dermis.

Choice A rationale: The statement "I need to void after sexual intercourse to flush microorganisms away from my urethra" is correct. Voiding after sexual intercourse can help prevent the ascent of microorganisms into the urethra and reduce the risk of urinary tract infections.
Choice B rationale: Wearing snug-fitting pants can contribute to a warm and moist environment, potentially increasing the risk of urinary tract infections rather than preventing them.
Choice C rationale: Wiping from the anus to the vagina after going to the bathroom can introduce microorganisms into the urethral area, increasing the risk of urinary tract infections.
Choice D rationale: Frequent bubble baths can disrupt the natural balance of microorganisms in the genital area and increase the risk of urinary tract infections.
