u u u u u u u u u u u u u u u u u


udose, to the wrong patient, or not given to the correct patient. Drugs classified as
u u u u u u u u u u u u u u


uhigh alert drugs include potassium, narcotics (opioids), insulin, cancer chemotherapy

u u u u u u u u u u u u u u u


umimics the actions of naturally occurring body substances (intrinsic drugs). A blocking
u u u u u u u u u u u


uagent is a drug u u u

, antagonist. A chemical would not necessarily be a drug at all. A duplicator is not a
u u u u u u u u u u u u u u u


upharmacologic term. u

a. Drug potency u


b Pharmacodynamics

ANS: D
The term pharmacokinetics refers to drug metabolism and how the body changes a
u u u u u u u u u u u u


udrug. Pharmacodynamics refers to how a drug works to change body function.
u u u u u u u u u u u


uDrug potency refers to how strongly or to what degree a drug exerts its effects.
u u u u u u u u u u u u u u
