Pharmacology is the study of the biologic effects of chemicals. Nurses are involved
with clinical pharmacology or pharmacotherapeutics, which is a branch of
pharmaco logythat deals with the uses ofdrugs to treat, prevent, and diagnose
D
disease. The ra diology nurse is administering a drug to help diagnose a disease.
The oncology nurse is administering a drug to help treata disease.
Y
Pharmacoeconomics includes any cos ts involved in drug
therapy.Pharmacodynamics involves how a drug affects the body and
pharmacokinetics is how the body acts on the body.

Feedback:
Narcotics with a high abuse potential are classified as Schedule II drugs be
cause of severe dependence liability. Schedule I drugs have high abuse pot
ential and no accepted medical use. Schedule III drugs have a lesser abuse
potential than II and an accepted medical use. Schedule IV drugs have lo
w abuse potential and limited dependence liability.

Feedback:
Phase III studies involve use of a drug in a vast clinical population in
which patients are asked to record any symptoms they experience while
taking t he drugs. Nurses maybe responsible for helping
collectandanalyze the in formation to be shared with the Food and Drug
ST
Administration (FDA) but w ould not conduct research independently
because nurses do not prescribe medications. Use of animals in drug
testing is done in the preclinical trials
. Select patients who are involved in phase II studies to participate in
studi es where the participants have the disease the drug is intended to
U
treat. T hese patients are monitored closely for drug action and
adverse effects. P
hase I studies involve healthy human volunteers who are usually paid for t
D
heir participation. Nurses may observe for adverse effects and toxicity.

What concept is considered when generic drugs are substituted for br
A) Bioavailability
B) Critical concentration
C) Distribution
D) Half-life
Ans: A
Feedback:

Bioavailability is the portion of a dose of a drug that reaches the systemic
circulation and is available to act on body cells. Binders used in a generic
drug may not be the same as those used in the brand name drug. Therefore
, the way the body breaks down and uses the drug may differ, which may
eliminate a generic drug substitution. Critical concentration is the amount
of a drug that is needed to cause a therapeutic effect and should not differ
between generic and brand name medications. Distribution is the phase of
pharmacokinetics, which involves the movement of a drug to the bodys ti
ssues and is the same in generic and brand name drugs. A drugs half-
life is the time it takes for the amount of drug to decrease to half the peak
level, which should not change when substituting a generic medication.

C) Are these medications safe to take during pregnancy?

Ans: D
Feedback:
ST
It is important for the nurse to specifically question use of over-the-
counter medications because patients may not consider them important.
T he patient is unlikely to know the meaning of orphan drugs unless they

U
are health care providers. Safety during pregnancy, use of a generic
medicat ion, or classification of orphandrugs are things the patientwould

After completing a pharmacology course nurses will have general drug inf
ormation needed for safe and effective medication administration but will
need to consult a drug guide for specific drug information before administe
ring any medication. Pharmacology is constantly changing, with new drugs
entering the market and new uses for existing drugs identified.
Continuing education in pharmacology is essential to safe practice. Nurses t
end to become familiar with the medications they administer most often, bu
t there will always be a need to research new drugs and also those the nurs

Category B indicates that animal studies have not demonstrated a risk to

pregnancy and no evidence of risk in later trimesters. Category A
indicates that adequate studies in pregnant women have not
demonstrated a risk to the fetus in the first trimester or in later

trimesters. Category C indicates that animal studi es have shown an
adverse effect on the fetus, but no adequate studies in humans.
Category D reveals evidence of human fetal risk, but the potential
benefits from the use of the drugs in pregnant women may outweigh
