MULTIPLE CHOICE
1. The nurse is teaching a patient how a medication works to treat an illness. To do this, the
nurse will rely on knowledge of:
a. clinical pharmacology.
b. drug efficacy.
c. pharmacokinetics.
d. pharmacotherapeutics.
ANS: D
Pharmacotherapeutics is the study of the use of drugs to diagnose, treat, and prevent
conditions. Clinical pharmacology is concerned with all aspects of drug–human
interactions.
Drug efficacy measures the extent to which a given drug causes an intended effect.
Pharmacokinetics is the study of the impact of the body on a drug.

2. What does it mean when a drug is described as easy to administer?
a. It can be stored indefinitely without need for refrigeration.
b. It does not interact significantly with other medications.
c. It enhances patient adherence to the drug regimen.
d. It is usually relatively inexpensive to produce.
ANS: C
A major benefit of drugs that are easy to administer is that patients taking them are
more likely to comply with the drug regimen. Drugs that are easy to give may have
the other attributes listed, but those properties are independent of ease of
administration.

,3. A patient tells the nurse that he was told by the prescriber that the analgesic he is taking is
very effective. Which statement by the patient demonstrates an understanding of the
drug’s effectiveness?
a. “I don’t have to worry about toxicity, since it takes a large amount of this drug to
cause an overdose.”
b. “It has no side effects and doesn’t interact with other drugs.”
c. “I only have to take it every 12 hours.”
d. “It might make me sleepy, and it lessens pain for several hours at a time.”
ANS: D
A drug is effective if it produces the intended effects, even if it also produces side
effects. Because no drug is completely safe, the level of toxicity does not determine
effectiveness. All drugs have side effects and many react with other substances; these
do not affect the drug’s effectiveness. Ease of administration is independent of a
drug’s effectiveness.

MULTIPLE RESPONSE
1. What are the properties of an ideal drug? (Select all that apply.)
a. Irreversible action
b. Predictability
c. Ease of administration
d. Chemical stability
e. A simple trade name
ANS: B, C, D
In addition to predictability, ease of administration, and chemical stability, other
properties include a reversible action so that any harm the drug may cause can be
undone and a simple generic name, because generic names are usually complex and
difficult to remember and pronounce.

2. Before administering a medication, what does the nurse need to know to evaluate how
individual patient variability might affect the patient’s response to the medication? (Select
all that apply.)
a. Chemical stability of the medication
, b. Ease of administration
c. Family medical history
d. Patient’s age
e. Patient’s diagnosis
ANS: C, D, E
The family medical history can indicate genetic factors that may affect a patient’s
response to a medication. Patients of different ages can respond differently to
medications. The patient’s illness can affect how drugs are metabolized. The chemical
stability of the medication and the ease of administration are properties of drugs.
