MULTIPLE CHOICE
1. Knowledge of pharmacology aids the dental professional in:
a. obtaining a patient’s health history.
b. administering drugs in the office.
c. handling emergency situations.
d. lifelong learning.
e. all of the above.
ANS: E
Correct: All of the choices are true.
Incorrect choices: Because many of our patients are being treated with drugs, knowledge of
pharmacology helps in understanding and interpreting patients’ responses to health history
questions. Knowledge of the therapeutic and adverse effects of medications obviously helps in
their proper administration in the office. Emergency situations may be caused by drugs or
treated by drugs; thus, knowledge of pharmacology is of great help, especially because a rapid
response is sometimes required. A clear understanding of the concepts of drug action, drug
handling by the body, and drug interactions will allow the dental practitioner to make proper
judgments and grasp the concepts relevant to new drug therapies on the market.
