Question 1
A nurse explains pharmacology to a group of first-year nursing
students. Which statement best describes pharmacology?
,A. The study of microorganisms that cause disease
B. The study of drugs and their effects on living organisms
C. The study of human anatomy and physiology
D. The study of surgical procedures
Correct Answer: B
Rationale:
Pharmacology is the scientific study of drugs, including their
sources, properties, actions, therapeutic uses, adverse effects,
and interactions with living organisms. Microbiology focuses on
microorganisms, anatomy studies body structures, and surgery
involves operative procedures.
Question 2
A nurse is reviewing the characteristics of an ideal medication.
Which characteristic should the nurse identify as most
desirable?
A. Produces therapeutic effects with minimal adverse effects
B. Has a long half-life regardless of the patient's condition
C. Requires frequent dosage adjustments
D. Is effective only when administered intravenously
Correct Answer: A
,Rationale:
An ideal drug achieves its intended therapeutic effect while
causing few or no adverse effects. Drug selection also considers
safety, effectiveness, patient convenience, and cost. Long half-
life, frequent dosage adjustments, or IV-only administration are
not characteristics of an ideal medication.
Question 3
A patient asks why a prescription medication requires a health
care provider's order. Which response by the nurse is most
appropriate?
A. "Prescription drugs are always more effective than over-the-
counter medications."
B. "Prescription medications require professional evaluation
because they may pose greater risks if used improperly."
C. "Prescription drugs never cause adverse effects."
D. "Over-the-counter drugs are not regulated."
Correct Answer: B
Rationale:
Prescription medications often require professional oversight
because of their potential for significant adverse effects, drug
interactions, or need for monitoring. Both prescription and OTC
, medications are regulated, and both may produce adverse
effects.
Question 4
A nurse administers an oral medication. Which process occurs
before the drug reaches systemic circulation?
A. Elimination
B. Absorption
C. Excretion
D. Metabolism
Correct Answer: B
Rationale:
Absorption is the movement of a drug from its site of
administration into the bloodstream. Elimination includes
metabolism and excretion, which occur after absorption.
Question 5
A nursing student asks why patient allergies are assessed before
administering medications. Which response is most accurate?
A. Allergies affect only drug absorption.
