Answer to Question 1

ANS: B
Stimulants can produce cardiovascular effects. Any patient reporting shortness of breath needs to be evaluated for cardiovascular problems. Anorexia, or poor appetite, is an expected effect of stimulants and is the desired effect when these drugs are used for obesity. Stimulants increase alertness and can cause insomnia, which is an expected affect at therapeutic doses. Loquaciousness is an expected effect at therapeutic doses.

Answer to Question 2

ANS: C
In large doses, caffeine produces nervousness and tremors; in very large doses, it can cause convulsions. People often consume caffeine when drinking alcohol to offset the sedative effects of the alcohol, and many college students consume highly caffeinated energy drinks with alcohol. Severe alcohol poisoning may produce seizures, but the patient would not be agitated and restless. Clonidine would cause somnolence, which would increase with alcohol. Strychnine causes severe muscle stiffness.
