A small-bore feeding tube is placed. Which technique will the nurse use to best verify tube placement?
Auscultation
X-ray
Aspiration of contents
pH testing
The Correct Answer is B
A: Auscultation, or listening for air injected into the tube, is not a reliable method for verifying feeding tube placement. It can lead to false positives and does not confirm the tube’s location accurately.
B: X-ray is the gold standard for verifying feeding tube placement. It provides a clear image of the tube’s position, ensuring it is correctly placed in the stomach or small intestine, reducing the risk of complications.
C: Aspiration of contents can help verify placement by checking the appearance and pH of the aspirate. However, it is not as definitive as an X-ray and can sometimes be inconclusive.
D: pH testing of aspirate can indicate whether the tube is in the stomach (acidic pH) or intestines (less acidic). While useful, it is not as reliable as an X-ray for confirming placement.

Correct Answer is C
Explanation
A: A trochanter roll is used to prevent external rotation of the hips, not to prevent plantar flexion contractures.
B: A sheepskin heel pad provides cushioning and helps prevent pressure ulcers on the heels but does not prevent plantar flexion contractures.
C: A footboard is used to prevent plantar flexion contractures by keeping the feet in a neutral position. This helps maintain proper alignment and prevents the muscles and tendons from shortening.
D: An abduction pillow is used to maintain hip abduction, typically after hip surgery, and does not prevent plantar flexion contractures.
Correct Answer is C
Explanation
A: Checking the client’s skin every 8 hours is not frequent enough to prevent skin breakdown in a client with urinary incontinence. More frequent checks are necessary to identify and address any issues promptly.
B: Cleaning the client’s skin and perineum with hot water can cause skin irritation and dryness. It is better to use lukewarm water and gentle cleansers to maintain skin integrity.
C: Applying a moisture barrier ointment to the client’s skin is an effective way to prevent skin breakdown. The ointment creates a protective barrier that helps keep moisture away from the skin, reducing the risk of irritation and breakdown.
D: Requesting a prescription for the insertion of an indwelling urinary catheter is not the best first-line intervention for preventing skin breakdown. Catheters carry a risk of infection and should be used only when absolutely necessary.
