PHARMACOKINETICS AND
PHARMACODYNAMICS COMPREHENSIVE
ASSESSMENT 2026 TEST BANK QUESTIONS
AND SOLUTIONS GRADED A+
●● What happens during drug absorption?
Answer: Drug enters the body and travels from the site of administration
into the body's circulation.
●● What occurs during drug distribution?
Answer: After absorption, the drug is distributed throughout the body;
some binds to plasma proteins, while the rest remains in blood and
interacts with receptors.
●● What is the major site of drug metabolism?
Answer: Liver.
●● What is the first pass effect?
Answer: The process where oral drugs are metabolized in the liver
before reaching systemic circulation, decreasing active drug
concentration.
●● What is excretion in pharmacokinetics?
, Answer: Ridding the body of inactive drug metabolites, primarily
through the kidneys.
●● How does drug absorption change in neonates and infants?
Answer: Gastric emptying is slower, gastric pH is higher until 2 years,
and less drug is metabolized in the liver.
●● What is pharmacogenetics?
Answer: The study of how people's genes affect their response to
medicine.
●● What is the sequence of the four processes of pharmacokinetics?
Answer: Absorption, distribution, metabolism, excretion.
●● What is the definition of pharmacodynamics?
Answer: The study of a drug's impact on the body and the interactions
involved.
●● What is an agonist?
Answer: A drug that interacts with a receptor to stimulate a desired
response.
●● What is an antagonist?
