Answer to Question 1

C
Cyclobenzaprine has significant anticholinergic effects and patients should be warned about dry mouth, blurred vision, and constipation. Tizanidine can cause hallucinations and psychotic symptoms. Methocarbamol may turn urine brown, black, or green, which is a harmless side effect. Tizanidine and metaxalone can cause liver toxicity and require monitoring.

Answer to Question 2

B
The interval between doses of the medication should be increased in older adult patients, because drugs that undergo the first pass effect may not be broken down as well as in an individual with full liver function. A higher dose of the medication is not indicated, because toxic effects could occur. A change in administration may be indicated in older adults, because their metabolism is affected. The interval between doses should not be reduced but increased.
