NR293/NR 293 QUIZ 1 – PHARMACOLOGY FOR NURSING PRACTICE
QUESTIONS 1–20
Question 1
What is drug nomenclature?
A. The chemical structure of a medication
B. The process by which drugs are metabolized
C. Refers to the drug’s name
D. The clinical indication for a drug
Correct Answer: C
Rationale:
Drug nomenclature refers to the naming system used for medications, including
chemical, generic, and brand names. Understanding drug names helps nurses safely
administer medications and avoid errors caused by look-alike or sound-alike drugs.
Nurses primarily use generic names in clinical practice because they are standardized
,and universally recognized. Accurate knowledge of drug nomenclature is essential for
medication safety.
Question 2
What is drug classification?
A. The route by which a medication is administered
B. The class name of a drug
C. The drug’s chemical composition
D. The legal status of the medication
Correct Answer: B
Rationale:
Drug classification groups medications based on similar characteristics such as
therapeutic use, mechanism of action, or chemical structure. Knowing a drug’s class
helps nurses anticipate effects, side effects, and nursing considerations. Drugs within
the same class often share similar adverse reactions and contraindications. This
knowledge improves clinical judgment and patient safety.
Question 3
What does pharmacotherapeutics refer to?
A. The absorption of drugs in the body
B. The study of adverse drug reactions
C. The clinical use of drugs to prevent and treat disease
D. The elimination of drugs from the body
Correct Answer: C
Rationale:
Pharmacotherapeutics focuses on the use of medications to diagnose, prevent, and
,treat disease. It emphasizes selecting the most appropriate drug for a specific patient
condition. Nurses apply pharmacotherapeutic principles when evaluating therapeutic
outcomes and monitoring effectiveness. This area links drug knowledge directly to
patient care.
Question 4
What does pharmacodynamics refer to?
A. The study of what the body does to the drug
B. The study of drug absorption
C. The study of what the drug does to the body
D. The movement of drugs through tissues
Correct Answer: C
Rationale:
Pharmacodynamics examines how drugs produce their effects on the body, including
therapeutic and adverse responses. It involves drug-receptor interactions and dose-
response relationships. Nurses use pharmacodynamic principles to understand why
drugs cause certain effects. This knowledge helps anticipate both desired outcomes
and potential side effects.
Question 5
What does drug metabolism refer to?
A. The absorption of a drug into the bloodstream
B. The biochemical alteration of a drug into an inactive or active metabolite
C. The elimination of drugs through the kidneys
D. The distribution of drugs throughout tissues
Correct Answer: B
, Rationale:
Metabolism is the biochemical process that transforms drugs into metabolites, which
may be active or inactive. This process primarily prepares drugs for excretion. Nurses
must consider metabolism when administering medications to patients with liver
impairment. Altered metabolism can lead to toxicity or reduced therapeutic effect.
Question 6
When does metabolism typically occur in the pharmacokinetic process?
A. Before absorption
B. Before distribution
C. After distribution
D. After excretion
Correct Answer: C
Rationale:
Metabolism usually occurs after a drug has been absorbed and distributed throughout
the body. Once in circulation, drugs are transported to the liver for metabolic
processing. Understanding the sequence of pharmacokinetics helps nurses predict
drug levels. This is especially important when dosing medications with narrow
therapeutic ranges.
Question 7
What does onset of action refer to?
A. The time it takes for a drug to reach peak level
B. The time required for a drug to elicit a therapeutic response after dosing
C. The length of time a drug remains in the body
D. The rate of drug elimination
Correct Answer: B
