Answer:

D. It prevents harmful substances from entering the cell. I am very confident in this answer. The cell membrane is selectively permeable, and its job is to let certain things in and to keep certain things out.

Why does the nurse need to keep the urine sterile while obtaining a sample from an indwelling urinary catheter?
Talja [164]

To ensure that any bacteria in the urine specimen are from the urine and not from the patient's skin, the nurse's hands, or the environment, the nurse will employ sterile technique to collect a urine specimen from an indwelling urinary catheter.

<h3>What are Indwelling urinary catheters? </h3>

A tube is placed in the bladder using aseptic approach during indwelling urinary catheterization.

Patients undergo the procedure for many different reasons, such as: Managing acute and chronic urinary retention; Accurately measuring urine output in critically ill patients; Bypassing an obstruction, such as an enlarged prostate gland in men; Administering medications directly into the bladder; and Conducting bladder function tests.

When all other conservative management techniques have been tried and failed, catheters can also be utilized to control incontinence and preserve skin integrity.

Numerous problems are linked to indwelling urinary catheterization, such as catheter-associated urinary tract infection (CAUTI), tissue injury, bypassing, and obstruction.
