computed tomography (CT) scan. The nurse working on the oncology unit administers

chemotherapy to patients who have cancer. At the Public Health Department, a

nurse administers a measles- mumps-rubella (MMR) vaccine to a 14-month-old child as a

routine immunization. Which branch of pharmacology best describes the actions of all three

nurses?

A) Pharmacoeconomics


B) Pharmacotherapeutics


C) Pharmacodynamics


D) Pharmacokinetics


Ans: B


Feedback:


Pharmacology is the study of the biologic effects of chemicals. Nurses are involved with clinical
bv b v bv bv bv bv bv b v bv bv b v bv bv bv



pharmacology or pharmacotherapeutics, which is a branch of pharmacology that deals with
bv bv b v b v bv bv bv b v b v bv b v bv



the uses of drugs to treat, prevent, and diagnose disease. The radiology nurse is
bv b v bv bv bv bv bv b v bv b v bv bv bv bv



administering a drug to help diagnose a disease. The oncology nurse is administering a
bv bv b v bv bv bv b v b v b v b v b v b v b v b v



drug to help treat a disease.
b v b v b v b v b v b v



Pharmacoeconomics includes any costs involved in drug therapy. Pharmacodynamics involves how a
bv bv bv bv bv bv bv bv bv bv bv



drug affects the body and pharmacokinetics is how the body acts on the body.

2. A physician has ordered intramuscular (IM) injections of morphine, a narcotic, every 4

hours as needed for pain in a motor vehicle accident victim. The nurse is aware this

drug has a high abuse potential.

liability. Schedule I drugs have high abuse potential and no accepted medical use.

Schedule III drugs have a lesser abuse potential than II and an accepted medical

use. Schedule IV drugs have low abuse potential and limited dependence liability.

3. When involved in phase III drug evaluation studies, what responsibilities would the nurse
b v b v b v b v b v b v b v b v b v b v b v b v



have?

Feedback:


Phase III studies involve use of a drug in a vast clinical population in which patients
b v b v b v b v b v b v b v b v b v b v b v b v b v b v b v



are asked to record any symptoms they experience while
b v b v b v taking the drugs.

b Nurses may be responsible for helping collect and analyze the information to
v b v b v b v b v bv b v b v b v b v b v b v



be shared with the Food and Drug Administration (FDA) but would not conduct
b v b v b v b v b v b v b v b v bv b v b v b v b v



research independently because nurses do not prescribe medications. Use of animals in
b v b v b v b v b v b v b v b v bv b v bv b v



drug testing is done in the preclinical trials. Select patients who are involved in
bv bv b v b v b v b v b v b v b v b v b v b v b v b v



phase II studies to participate in studies where the participants have the disease the
bv b v b v b v b v b v bv b v b v b v b v b v b v bv



drug is intended to treat. These patients are monitored closely for drug action and
b v b v b v bv b v b v b v b v b v b v b v b v b v b v



adverse effects. Phase I studies involve healthy human volunteers who are usually paid for their
bv b v b v b v bv bv bv bv bv bv bv bv bv bv bv



participation. Nurses may observe for adverse effects and toxicity.

4. What concept is considered when generic drugs are substituted for brand name drugs?
b v b v b v b v b v b v b v b v b v b v b v b v




A) Bioavailability


B) Critical concentration b v




C) Distribution


D) Half-life


Ans: A


Feedback:


Bioavailability is the portion of a dose of a drug that reaches the systemic circulation and
bv bv bv bv bv bv bv bv b v bv bv b v bv b v bv



is available to act on body cells. Binders used in a generic drug may not be the same
bv bv bv bv b v bv bv b v b v bv bv b v b v bv bv b v b v b v



as those used in the brand name drug. Therefore, the way the body breaks down and
bv b v b v bv bv b v bv b v b v b v b v b v b v bv b v b v



uses the drug may differ, which may eliminate a generic drug substitution. Critical
b v b v b v b v b v b v b v bv b v b v b v bv b v



concentration is the amount of a drug that is needed to cause a therapeutic effect and
b v bv b v bv b v bv b v bv b v b v bv bv bv bv b v b v



b should not differ between generic and brand name
v b v medications. Distribution
