Chapter 2 Pharmacodynamics
1) The pharmacologic actions of a drug that determine its therapeutic effects are called:
A) pharmacology
B) pharmacokinetics
C) pharmacognosy
D) pharmacodynamics
Answer: D
Explanation: D) The pharmacologic actions of a drug that determine its therapeutic effects are
called pharmacodynamics, which can also determine the drug’s adverse effects. The term
pharmacodynamics describes how a medication causes changes in the body. It studies the
biochemical as well as the physiologic effects of drugs, along with the molecular mechanisms
used to produce these effects.
2) Which of the following body fluids is the most commonly used to characterize pharmacologic
drug actions?
A) Urine
B) Cerebrospinal fluid
C) Blood
D) Sputum
Answer: C
Explanation: C) Blood is the body fluid most commonly used to characterize pharmacologic
drug actions. Usually, there are correlations between pharmacokinetics and pharmacodynamics
that demonstrate the relationship between drug dose and blood or other biological fluid
concentrations.
3) Which of the following can determine the dose-effect relationship?
A) Pharmacokinetics
B) Pharmacodynamics
C) Both
D) Neither
Answer: C
Explanation: C) Both pharmacokinetics and pharmacodynamics can determine the dose-effect
relationship, which is also called the dose-response relationship. It is the relationship between the
dose of a drug (or other agent) that produces therapeutic effects and the potency of the effects on
an individual person.
