A client is having difficulty having a bowel movement laying on the bedpan. What is the physiologic reason for this problem?
It is painful to sit on a bedpan.
The position encourages the Valsalva maneuver.
The position does not facilitate downward pressure.
The cause is unknown and requires further study.
The Correct Answer is C
A. It is painful to sit on a bedpan. Discomfort may be a factor, but pain alone does not explain the difficulty in having a bowel movement.
B. The position encourages the Valsalva maneuver. The Valsalva maneuver (straining against a closed airway) can occur in any position, but posture is the primary problem here.
C. The position does not facilitate downward pressure. The seated position allows for gravity and proper abdominal muscle engagement, making defecation easier. Lying down does not facilitate intra-abdominal pressure.
D. The cause is unknown and requires further study. The relationship between position and defecation is well understood in physiology.

Correct Answer is A
Explanation
A. Placing an indwelling urinary catheter: Indwelling urinary catheters are a leading cause of catheter-associated urinary tract infections (CAUTIs), which are common healthcare-associated infections.
B. Administering medications through an NG tube: While NG tubes can introduce bacteria, they are not as high-risk as urinary catheters, which provide a direct route for infection.
C. Changing a sacral wound dressing: While wounds can become infected, proper wound care techniques minimize risk. Urinary catheters pose a greater risk due to prolonged exposure to bacteria.
D. Replacing an ostomy appliance: While maintaining hygiene is important, ostomy appliances are not a major source of healthcare-associated infections compared to urinary catheters.
Correct Answer is B
Explanation
A. A patient who is lying on wrinkled sheets: Wrinkled sheets can cause pressure injuries, but they do not directly lead to shearing.
B. A patient who is pulled up in the bed by the nurse: Shearing occurs when the skin remains in place while underlying tissues move, often when a patient is dragged up in bed instead of lifted. This can damage skin layers and underlying tissues.
C. A patient who is frequently incontinent: Incontinence increases the risk of moisture-associated skin damage and pressure injuries but is not directly related to shearing.
D. A patient who is noted to have slough tissue: The presence of slough (dead tissue in a wound) indicates existing tissue damage but does not suggest an increased risk of shearing.
