Related Questions

Correct Answer is ["A","B","C"]

Explanation

A. Muscle atrophy

Lack of movement leads to wasting of muscle tissue over time, a common consequence of immobility.

B. Venous pooling

Immobility causes reduced venous return, leading to venous stasis or pooling, increasing the risk of DVT.

C. Urinary stasis

Lying flat for extended periods contributes to bladder emptying issues, increasing risk for UTIs and renal calculi.

D. Increased depth of respirations

Immobility leads to shallow breathing and reduced lung expansion, not deeper respirations.

E. Increased metabolic rate

Immobility generally results in a decreased metabolic rate due to lower energy needs.

Correct Answer is C

Explanation

A. Raise the head of the bed to 30 to 45 degrees.

While head elevation for comfort is acceptable, it is not the primary responsibility for CPM care.

B. Elevate the machine at the foot of the bed on one pillow.

The CPM machine should lie flat along the bed frame. Elevation on a pillow can cause misalignment or malfunction.

C. Set the proper flexion and extension limits.

The nurse must confirm that the machine is set according to the provider's orders for proper range of motion and to prevent injury.

D. Keep the operated knee warm.

While comfort is important, this is not a priority of CPM machine care and doesn't directly relate to its function.
