Final answer:
The nurse should intervene for the finding of decreased bowel sounds and abdominal distension in the immobile client.
Step-by-step explanation:
The nurse should intervene for the finding of decreased bowel sounds and abdominal distension in the immobile client. This could indicate a possible bowel obstruction or impairment in gastrointestinal motility.
Increased muscle strength in the lower extremities is actually a positive finding, as immobility often leads to muscle weakness.
Dependent edema in the lower limbs is a common finding in clients who are immobile for long periods of time and does not require immediate intervention.
Pink and warm skin in the sacral area is also a normal finding and does not require intervention.
