A nurse is planning to insert a female external urinary catheter for a client.
Which of the following actions should the nurse plan to take?
Replace the external urinary catheter once each day.
Insert the catheter into the client's urethra.
Apply a barrier cream to the client's perineal skin.
Connect the catheter to continuous wall suction.
The Correct Answer is C
Choice A rationale
Replacing the external urinary catheter once each day is unnecessary. The catheter should be changed based on clinical judgment and manufacturer's guidelines to maintain hygiene.
Choice B rationale
Inserting the catheter into the client's urethra is incorrect for an external urinary catheter. External catheters are designed to be placed outside the body.
Choice C rationale
Applying a barrier cream to the client's perineal skin is correct. Barrier creams protect the skin from moisture and prevent skin breakdown and irritation caused by urine.
Choice D rationale
Connecting the catheter to continuous wall suction is not appropriate. External urinary catheters should be connected to a drainage bag for proper urine collection. .

Correct Answer is C
Explanation
Choice C rationale
The large intestine absorbs water and electrolytes from the remaining indigestible food matter, forming and eliminating solid waste (stool). This absorption process is vital for
maintaining the body's fluid and electrolyte balance.
Choice A rationale
The large intestine does not produce vitamin D; this occurs in the skin when exposed to sunlight. The large intestine’s primary functions are absorption and waste formation.
Choice B rationale
Preventing the reflux of food into the esophagus is the function of the lower esophageal sphincter, not the large intestine. The large intestine deals with waste processing rather than regulating esophageal function.
Choice D rationale
The secretion of digestive enzymes is a function of the pancreas, stomach, and small intestine. The large intestine does not secrete enzymes but focuses on absorbing water and electrolytes.
Correct Answer is A
Explanation
Choice A rationale
Reflex incontinence is caused by neurological impairment or damage, such as spinal cord injury, which results in a loss of voluntary control over urination. The bladder muscle contracts involuntarily, causing urine leakage.
Choice B rationale
Overflow incontinence occurs when the bladder cannot empty properly, leading to frequent or constant dribbling of urine. It is not typically associated with nerve damage from spinal cord injury.
Choice C rationale
Stress incontinence is caused by physical movement or activity—such as coughing, sneezing, or heavy lifting—that puts pressure on the bladder, leading to urine leakage. It is not related to nerve damage or neurological conditions.
Choice D rationale
Urge incontinence is characterized by a sudden, intense urge to urinate, followed by involuntary urine leakage. It is usually caused by an overactive bladder or other conditions affecting bladder function, but not directly by nerve damage from spinal cord injury.
