Introductory Clinical Pharmacology –Questions with Detailed Rationales
SECTION 1: GENERAL PRINCIPLES OF PHARMACOLOGY (Q1–Q25)
Q1. A nursing instructor is preparing a teaching plan for a group of nursing students
about pharmacology. When describing this topic, the instructor would focus the
discussion on which of the following as an essential aspect?
A) Drug name
B) Drug class
C) Drug action
D) Drug source
Correct Answer: C) Drug action
Rationale: Pharmacology is the study of drugs and their action on living organisms.
Thus, an essential aspect of pharmacology is drug action. An understanding of the drug
name, drug class, and drug source is important, but the most critical aspect related to
pharmacology is how the drug acts in the body.
Q2. A nursing student is preparing to administer a prescribed drug to a patient. The
student reviews information about the drug and its actions. Which of the following

D) Trade name
E) Nonproprietary name
Correct Answer: A, B, D, E
Rationale: Throughout the process of development, drugs may have several names
assigned to them including a chemical name, a generic (nonproprietary) name, an
official name, and a trade or brand name.
Q5. A drug may be classified by which of the following? Select all that apply.
A) The chemical type of the drug's active ingredient
B) The way the drug is used to treat a specific condition
C) The generic name of the drug
D) The trade name of the drug
E) The nonproprietary name of the drug
Correct Answer: A, B
Rationale: A drug may be classified by the chemical type of the active ingredient or by

Q6. A nurse suspects the client had an adverse reaction to a prescribed medication
due to an interaction with an unreported over-the-counter supplement. Which
action by the nurse will best assist in preventing future similar incidents?
A) File a report with MedWatch
B) File a report with the State Board of Nursing
C) Instruct the client to avoid combining medications in the future
D) Document the incident and report it to the health care provider
Correct Answer: A) File a report with MedWatch

and throat.
Q8. The nurse is preparing to teach a client about a new drug which is in the fourth
phase of development. Which activity will the nurse explain best illustrates this
phase?
A) Health care providers report adverse effects to FDA
B) Healthy volunteers are involved in the test
C) In vitro tests are performed using human cells
D) The drug is given to clients with the disease
Correct Answer: A) Health care providers report adverse effects to FDA
Rationale: The postmarketing surveillance phase of drug development encourages
health care professionals to report adverse effects of drugs to the FDA using MedWatch.
Phase 1 of clinical testing involves 20 to 100 healthy volunteers.
