Pharmacology is the study of the biologic effects of chemicals. Nurses are involved with clinical ph

armacology or pharmacotherapeutics, which is a branch of pharmacology that deals with the uses

ofdrugs to treat, prevent, and diagnose disease. The radiology nurse is administering a drug to help

diagnose a disease. The oncology nurse is administering a drug to help treat a disease.
K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7



Pharmacoeconomics includes any costs involved in drug therapy. Pharmacodynamics involves how K7 K7 K7 K7 K7 K7 K7 K7 K7 K 7 K7


adrug 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 because of severe dependence lia

bility. Schedule I drugs have high abuse potential and no accepted medical use. Schedule III
K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7


drugs have a lesser abuse potential than II and an accepted medical use. Schedule IV drug

Feedback:


Phase III studies involve use of a drug in a vast clinical population in which patients are asked to

Feedback:


Bioavailability is the portion of a dose of a drug that reaches the systemic circulation and is availa
K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K 7


ble to act on body cells. Binders used in a generic drug may not be the same as those used in the
K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K 7 K7 K


brand name drug. Therefore, the way the body breaks down and uses the drug may differ, which
7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K 7



may eliminate a generic drug substitution. Critical concentration is the amount of a drug that is
K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K 7 K7 K7


needed to cause a therapeutic effect and should not differ between generic and brand name medi

cations. Distribution is the phase of pharmacokinetics, which involves the movement of a drug to

the body’s tissues and is the

life is the time it takes for the amount of drug todecrease to half the peak level, which should not

change when substituting a generic medication.

ions, the nurse asks what priority question?
K7 K7 K7 K7 K7 K7




Do you take any generic medications?
K7 K7 K7 K7 K7




Are any of these medications orphan drugs? Are

Ans: D


Feedback:


It is important for the nurse to specifically question use of over-the-
K7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7



counter medications because patients may not consider them important. The patient is unlikely to
K7 K7 K 7 K7 K7 K7 K7 K7 K7 K7 K7 K7 K7
