Answer to Question 1

Correct Answer: 1, 2, 4
The electromyelogram (EMG) measures the electrical activity of skeletal muscles at rest. When preparing the patient for the testing, instruct the patient to avoid behaviors that may influence the test. This includes no smoking for 3 hours before the test and avoiding fluids containing caffeine. The physician must have the final determination regarding which medications can be allowed prior to the testing.

Answer to Question 2

Correct Answer: 3
Skeletal muscle is the only muscle in the body that allows musculoskeletal function. Cardiac muscle is exclusive to the heart and smooth muscle is found in organs and is not under voluntary control. Smooth muscle is not needed for musculoskeletal function.
