Multiple Choices
1. A nurse working in radiology administers iodine to a patient having a CT scan, an oncology nurse administers
chemotherapy, and a public health nurse administers an MMR vaccine to a child. Which branch of pharmacology
best describes the actions of all three nurses?
A) Pharmacoeconomics
B) Pharmacotherapeutics
C) Pharmacodynamics
D) Pharmacokinetics
Answer: B
Pharmacotherapeutics is the branch of pharmacology dealing with the use of drugs to treat, prevent, and diagnose
disease. The radiology nurse uses a drug to diagnose, the oncology nurse uses a drug to treat, and the public
health nurse uses a drug to prevent disease.
2. A physician orders intramuscular morphine every 4 hours as needed for pain in a motor vehicle accident victim.
The nurse knows this drug has high abuse potential. Under what schedule would morphine be classified?
A) Schedule I
B) Schedule II
C) Schedule III
D) Schedule IV
Answer: B
Narcotics with high abuse potential are classified as Schedule II drugs because of severe dependence liability.
Schedule I drugs have high abuse potential but no accepted medical use, Schedule III have lesser abuse potential,
and Schedule IV have low abuse potential.
, 3. A nurse is involved in phase III drug evaluation studies. What responsibility would the nurse have?
A) Working with animals given experimental drugs
B) Choosing appropriate patients for the drug study
C) Monitoring and observing patients closely for adverse effects
D) Conducting research to determine drug effectiveness
Answer: C
Phase III studies involve using a drug in a vast clinical population where patients record symptoms. Nurses may
help collect and analyze information for the FDA but do not conduct research independently. Animal testing occurs
in preclinical trials.
4. What concept is considered when generic drugs are substituted for brand-name drugs?
A) Bioavailability
B) Critical concentration
C) Distribution
D) Half-life
Answer: A
Bioavailability is the portion of a drug dose that reaches systemic circulation. Binders used in generic drugs may
differ from brand-name drugs, affecting how the body breaks down and uses the drug, which may eliminate
generic substitution.
5. A nurse assesses a patient's home medication use. After listening to the patient list current medications, what
priority question should the nurse ask?
A) Do you take any generic medications?
B) Are any of these medications orphan drugs?
