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.
Correct Answer: 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.
Correct Answer: 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.”
Correct Answer: 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

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
Correct Answer: 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
Correct Answer: 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.
