Answer to Question 1

Correct Answer: 1
Rationale: The exact mechanism by which skeletal muscle relaxants work is not fully understood. It is believed that they inhibit upper motor neuron activity, causing CNS depression.

Answer to Question 2

Correct Answer: 3
Rationale: Muscle spasms can be treated with a variety of pharmacologic and non-pharmacologic methods. When the cause is unknown, a more general approach is indicated, such as analgesics, muscle relaxants, and massage. Antibiotics and casting are not indicated for muscle spasms. Fluid and electrolyte replacement can be indicated, if determined to be the cause.
