A nurse is caring for a client who is prescribed bedrest. The plan of care indicates that the client should perform isometric exercises every 2 hr. Which of the following actions should the nurse take as directed by the plan of care?

Correct Answer: A - Instruct the client to tighten muscle groups for a short period, then relax.

Rationale:
1. Isometric exercises involve contracting muscles without joint movement.
2. Performing isometric exercises every 2 hours helps prevent muscle atrophy and maintain muscle strength.
3. Instructing the client to tighten muscle groups then relax reflects the correct technique for isometric exercises.
4. This action promotes muscle engagement without joint movement, aligning with the purpose of isometric exercises.

Summary of Incorrect Choices:
B. Moving the client's limbs through their complete range of motion involves dynamic exercises, not isometric exercises.
C. Asking the client to move her arms and legs with resistance involves isotonic exercises, not isometric exercises.
D. Having the client move each limb independently through its complete range of motion also involves dynamic exercises, not isometric exercises.
