,Question 1
A nurse is teaching a group of students about the difference
between a drug’s generic name and brand name. Which
statement by a student indicates correct understanding?
A. “The brand name identifies the active ingredient and is used
worldwide.”
B. “The generic name is the standardized name for the active
drug ingredient.”
C. “The generic name changes depending on the manufacturer.”
D. “Brand names are assigned by the World Health
Organization.”
Correct Answer: B
Rationale:
The generic (nonproprietary) name is the standardized name
for the active ingredient and remains the same regardless of
manufacturer. Brand names are proprietary names chosen by
manufacturers and may vary among companies and countries.
Question 2
A nurse is explaining why a newly approved medication
continues to be monitored after it reaches the market. Which
reason is most important?
A. Manufacturing costs may change over time.
,B. Rare adverse effects may not appear during preapproval
studies.
C. Drug patents must be renewed annually.
D. The drug’s mechanism of action may change after approval.
Correct Answer: B
Rationale:
Clinical trials before approval involve limited numbers of
participants and may not detect rare or long-term adverse
effects. Postmarketing surveillance helps identify uncommon
safety issues once the drug is used in larger populations.
Question 3
A patient asks why a medication dose differs from that
prescribed for a family member taking the same drug. Which
nursing response is most accurate?
A. “Drug doses are always based solely on body weight.”
B. “Patients generally respond identically to medications.”
C. “Individual factors such as age, organ function, and other
medications can affect dosing.”
D. “Higher doses are always safer for adults.”
Correct Answer: C
Rationale:
, Drug dosing is influenced by factors such as age, kidney and
liver function, genetics, body size, disease states, and
concurrent medications. Patients do not respond identically to
medications.
Question 4
A nurse is reviewing phases of clinical drug development. Which
activity is most characteristic of a phase III clinical trial?
A. Testing a drug in laboratory animals
B. Determining basic pharmacokinetics in a small group of
healthy volunteers
C. Comparing the new drug with standard therapy in a larger
patient population
D. Monitoring adverse events after the drug is marketed
Correct Answer: C
Rationale:
Phase III trials involve larger groups of patients and compare
the new therapy with existing treatments or placebo to assess
effectiveness and safety before potential regulatory approval.
Question 5
A nurse is caring for a patient enrolled in a double-blind clinical
trial. What does “double-blind” mean?
