Question: What is pharmacology?
A. The study of body systems only
B. The study or science of drugs, including absorption, metabolism, and mechanisms of
action
C. The study of surgical techniques
D. The study of nutrition
Answer: B
Rationale: Pharmacology is the branch of science that focuses on drugs, how they act in the
body, and how the body processes them. It includes absorption, distribution, metabolism,
and mechanisms of action.
Question: What defines a drug?
A. Any substance used in surgery
B. Any chemical that affects the physiologic processes of a living organism
C. Only natural plant-based substances
D. Only substances prescribed by a physician
Answer: B
Rationale: A drug is any chemical that produces a biological effect, whether therapeutic or
adverse, on living organisms.
Question: Which are the three basic areas of pharmacology?
A. Anatomy, Physiology, Biochemistry
B. Pharmaceutics, Pharmacokinetics, Pharmacodynamics
C. Pharmacognosy, Toxicology, Pathology
D. Genetics, Microbiology, Immunology
,Answer: B
Rationale: Pharmacology is divided into three core areas:
• Pharmaceutics – how drug forms affect the body
• Pharmacokinetics – what the body does to the drug
• Pharmacodynamics – what the drug does to the body
Question: What does pharmaceutics study?
A. How drugs are marketed
B. How drug forms influence effects on the body
C. How to prescribe medications
D. The economic cost of drugs
Answer: B
Rationale: Pharmaceutics focuses on the formulation of drugs (e.g., tablets, liquids) and how
these forms affect absorption and efficacy.
Question: What is the half-life of a drug?
A. The time it takes for a drug to reach peak effect
B. The time required for 50% of the drug to be eliminated from the body
C. The total duration of drug therapy
D. The time until a drug causes toxicity
Answer: B
Rationale: Half-life measures how quickly a drug’s plasma concentration decreases by half,
important for dosing schedules.
Question: What is meant by “steady state” in pharmacokinetics?
A. When the drug is fully absorbed in the stomach
B. When the amount of drug eliminated equals the amount absorbed with each dose
C. When a drug reaches its toxic level
D. When the drug stops working
Answer: B
Rationale: Steady state occurs after repeated dosing when plasma drug levels plateau,
ensuring consistent therapeutic effect.
,Question: What does “onset” refer to?
A. Time for a drug to start working
B. Maximum drug effect
C. Duration of drug effect
D. Time until excretion
Answer: A
Rationale: Onset is the period between drug administration and the start of its therapeutic
effect.
Question: What does “peak” refer to in pharmacology?
A. Time when the drug starts working
B. Time when the drug has maximum effect
C. Time of drug elimination
D. Drug half-life
Answer: B
Rationale: Peak refers to the point of maximum drug concentration in the blood and
maximum therapeutic effect.
Question: What is “duration” of a drug’s action?
A. The length of time the drug is detectable in urine
B. The length of time a drug produces its therapeutic effect
C. The time to reach peak concentration
D. Time until a drug is metabolized
Answer: B
Rationale: Duration is the period during which the drug produces a clinically significant
effect.
Question: What is the trough level of a drug?
A. Lowest blood concentration before next dose
B. Highest concentration after a dose
C. Average plasma concentration
D. Therapeutic index
Answer: A
Rationale: The trough level ensures that the drug concentration remains within the
therapeutic range and prevents toxicity.
, Question: What is drug toxicity?
A. Ineffective drug use
B. Occurs when peak blood level is too high
C. Maximum therapeutic effect
D. Drug metabolism
Answer: B
Rationale: Toxicity results from excessive drug accumulation or high peak levels,
potentially causing adverse effects.
Question: What is therapeutic drug monitoring?
A. Observing patient adherence
B. Measuring drug levels to ensure safety and effectiveness
C. Calculating drug cost
D. Monitoring side effects only
Answer: B
Rationale: Therapeutic drug monitoring prevents toxicity and ensures optimal therapeutic
effect, especially for drugs with narrow therapeutic indices.
Question: What is the role of a receptor in pharmacology?
A. Site where drugs are metabolized
B. Site where drug-receptor interactions occur to produce effects
C. Organ for excretion
D. Enzyme that breaks down drugs
Answer: B
Rationale: Receptors are specific sites on cells where drugs bind to produce their intended
effect.
Question: What does “affinity” mean in drug-receptor interactions?
A. Strength of drug binding to a receptor
B. Rate of drug metabolism
C. Duration of drug effect
D. Drug’s toxic potential
Answer: A
Rationale: Affinity indicates how strongly a drug binds to its receptor, influencing its
potency.
