Correct Answer is D

Explanation

A. One minute may not provide a sufficient duration to declare absent bowel sounds, especially if the client has a slower bowel motility.
B.

Listening for 10 minutes in each quadrant is excessive and not supported by clinical guidelines. It would unnecessarily delay care and increase patient discomfort.

C. One minute in each quadrant might not provide an adequate assessment time.
D. This is the correct answer because clinical guidelines recommend auscultating for at least 5 minutes in each quadrant before concluding that bowel sounds are absent. This ensures sufficient time to detect infrequent bowel sounds and accurately assess the situation.

A. Hyperalgesia B. Peripheral neuropathy C. Hyperparalysis D. Lesion of the sensory cortex

Correct Answer is B

Explanation

A. Hyperalgesia refers to increased sensitivity to pain stimuli, not specifically related to the inability to feel vibrations.
B. Peripheral neuropathy, a common complication of diabetes, often leads to sensory deficits, especially in distal extremities like the toes and feet.
C. Hyperparalysis is not a recognized term in neurology.
D. A lesion of the sensory cortex would likely present with broader sensory deficits rather than a specific loss of vibration sensation in the distal lower extremities.
