Answer to Question 1

ANS: B
Distribution of a drug once it has been absorbed depends on its solubility. Lipid-soluble drugs rapidly cross cellular membranes because of the highly permeable nature of capillary endothelial membranes. Drugs that are insoluble in lipids are limited in their ability to pass capillary endothe-lial membranes and therefore have a restricted distribution.

Answer to Question 2

ANS: B
Pharmacodynamics is the study of the relationship between the concentration of a drug and the response obtained in the patient; in other words, how the drug acts at various sites in the body. Most often, the sites of action are receptors on the specific cell, tissue, or organ, where the drug initiates a chain of biochemical events that culminates in changes in physiologic functioning of the cell, or the activity of an enzyme or of an intracellular protein.
