CNPR Pharmacology & Medical Terminology 2 — Questions and Answers
Question 1: Which term describes a drug that binds to a receptor and produces a biological response?
- Antagonist
- Agonist (Correct answer)
- Inhibitor
- Modulator
Correct answer: Agonist
An agonist binds to a receptor and activates it to produce a pharmacological response.
Question 2: The medical prefix 'brady-' refers to which condition?
- Fast
- Slow (Correct answer)
- Irregular
- Absent
Correct answer: Slow
The prefix 'brady-' means slow, as in bradycardia (slow heart rate).
Question 3: Which pharmacokinetic process refers to the transformation of a drug into metabolites by the liver?
- Absorption
- Distribution
- Metabolism (Correct answer)
- Excretion
Correct answer: Metabolism
Metabolism is the biochemical transformation of drugs, primarily occurring in the liver via cytochrome P450 enzymes.
Question 4: The suffix '-itis' in medical terminology indicates:
- Surgical removal
- Inflammation (Correct answer)
- Disease of
- Tumor
Correct answer: Inflammation
The suffix '-itis' denotes inflammation, as in appendicitis (inflammation of the appendix).
Question 5: What does 'bioavailability' measure in pharmacokinetics?
- How quickly a drug is absorbed
- The fraction of administered drug that reaches systemic circulation (Correct answer)
- The volume in which a drug distributes
- The rate at which a drug is eliminated
Correct answer: The fraction of administered drug that reaches systemic circulation
Bioavailability is the fraction of an administered dose that reaches the systemic circulation unchanged.
Question 6: The term 'hypertension' is best broken down as:
- Under + tension
- Over + tension (Correct answer)
- Without + pressure
- Between + pressure
Correct answer: Over + tension
Hypertension combines 'hyper-' (above normal/excessive) with 'tension' (pressure), meaning high blood pressure.
Question 7: Which drug classification is used to describe medications that reduce fever?
- Analgesic
- Antipyretic (Correct answer)
- Antiemetic
- Antitussive
Correct answer: Antipyretic
Antipyretics are drugs that reduce fever; the prefix 'anti-' means against and 'pyretic' relates to fire/fever.
