Which of the following best describes a patient who cannot control urination or defecation?

Aseptic refers to a state of being free from contamination by pathogens or disease-causing microorganisms. It does not relate to control over bodily functions but rather to cleanliness and sterility in medical contexts.

Excretory pertains to the system responsible for the removal of waste products from the body, such as urine and feces. While it describes the function of eliminating waste, it does not indicate any impairment in the ability to control these processes.

Impotent typically refers to the inability to achieve or maintain an erection in males, a condition related to sexual function rather than the control of urination or defecation. This term does not apply to the context of incontinence.

Incompetent generally denotes a lack of ability or capacity to perform a task effectively. While it might suggest a deficiency, it does not specifically address the issue of controlling urination or defecation, making it an inappropriate descriptor in this scenario.
