The nurse is teaching a client how to perform isometric exercises. What is an example of an isometric exercise?
1. Exercising both arms and legs extremities simultaneously
2. Running in place for 5 minutes, then taking a pulse check
3. Press back of the knee down and lift heel from the bed
4. Moving arms and legs through full range of motion
Answer: 3
Isometric exercises involve initiating a muscle contraction by pressing against a stationary object, or resistance (pushups, hip lifts). Exercising both arms and legs simultaneously or running in place are not examples of isometric exercises. Moving extremities through full range of motion is not an example of isometric exercise.
