Answer to Question 1

A, B, C, D
Feedback:
Numerous factors affect the rate and extent of drug absorption, including dosage form, route of administration, blood flow to the site of administration, GI function, the presence of food or other drugs, and other variables. Agonist activity is a relevant variable, but this is not an aspect of absorption.

Answer to Question 2

B
Feedback:
Although antitussives continue to be used and adults report beneficial effect in reducing cough, antitussives, particularly dextromethorphan, have not been demonstrated to be effective in children and adolescents. Adverse effects of dextromethorphan in children include behavioral disturbances and respiratory depression, not high blood pressure.
