A client, whose cancer is very advanced, has decided not to have surgery or chemotherapy. The nurse believes that, as a rule, everything possible should be done to preserve life. However, once the client has decided, the nurse supports the decision. Which ethical principle provides the best basis for the nurse's actions?

A. frequent enuresis: Frequent enuresis refers to the involuntary loss of urine during the day or night, often associated with bedwetting. It does not specifically describe the sudden, compelling need to urinate described by the client.

B. urinary frequency: Urinary frequency is the need to urinate more often than usual, which may or may not be associated with urgency. It does not fully capture the sudden, urgent need to urinate described by the client.

C. urinary urgency: Urinary urgency is the sudden, compelling need to urinate that cannot be delayed. This aligns with the client's description of feeling like they have to go immediately and cannot wait. Therefore, this is the most appropriate choice.

D. urge incontinence: Urge incontinence involves the involuntary loss of urine associated with a sudden, strong desire to urinate. While similar to urinary urgency, it specifically refers to the leakage of urine that can occur due to the inability to reach the toilet in time after feeling the urge to urinate. However, the client's statement does not indicate actual urine leakage, making this option less appropriate than urinary urgency.

A. Lubricating: A lubricating enema typically refers to an enema solution that contains a lubricant, such as mineral oil, to help soften feces and facilitate their passage from the rectum. Lubricating enemas are used to alleviate constipation by easing the passage of stool. However, soapsuds enemas do not primarily function as lubricating enemas.

B. Irritating: This is the correct option. Soapsuds enemas contain soap or detergent mixed with water, and their primary action is to irritate the intestinal mucosa. The irritation stimulates peristalsis, which promotes bowel evacuation. Soapsuds enemas are often used to relieve constipation by inducing bowel movements through irritation of the intestinal lining.

C. Dilating: Dilating refers to widening or enlarging a structure. While enemas, including soapsuds enemas, may contribute to the relaxation and dilation of the rectum and lower bowel, the primary action of a soapsuds enema is to stimulate bowel evacuation through irritation rather than dilation.

D. Softening: Softening enemas typically involve the introduction of a solution, such as a mineral oil-based solution, to soften feces and facilitate their passage from the rectum. While softening enemas help alleviate constipation by softening stool consistency, soapsuds enemas do not primarily function as softening enemas. Their main action is to stimulate bowel evacuation through irritation.
