Instruct the client to tighten muscle groups for a short period, then relax.

Move the client's limbs through their complete range of motion.

Ask the client to move her arms and legs while applying slight resistance.

Have the client move each limb independently through its complete range of motion.

Answer and Explanation

The Correct Answer is A

A.   Isometric exercises involve contracting or tensing muscles without actually moving the joint. Instructing the client to tighten muscle groups for a short period and then relax is the correct approach for isometric exercises. This action helps activate and strengthen specific muscle groups without moving the joints.
B.   Moving the client's limbs through their complete range of motion is known as passive range of motion exercises. These exercises are important for maintaining joint flexibility but are not isometric.
C.   Asking the client to move her arms and legs while applying slight resistance is known as resisted range of motion exercises. These exercises involve active movement against resistance and are not considered isometric.
D.   Having the client move each limb independently through its complete range of motion is known as active range of motion exercises. These exercises involve voluntary
movement of each joint through its full range of motion and is not isometric.
