Answer to Question 1

B
Electromyography (EMG) is used to detect abnormal nerve transmission to the muscle and ab-normal muscle function, and to assess the rehabilitation progress. Before the test, smoking and use of caffeine should be ceased for 3 hours. The test usually takes 1 hour.

Answer to Question 2

B, C
A person with a dark complexion can be assessed for cyanosis by examining the gums and the roof of the mouth. Cyanosis is not usually apparent in the conjunctiva or palms of the hands. The nail beds tend to be darker in dark-skinned individuals so this would not render an accurate as-sessment of cyanosis.
