TOPIC 1: PHARMACOKINETICS
9 Questions • 9.0% of Exam • This topic covers the processes of drug absorption, distribution, metabolism, and excretion.
QUESTION 1
The study of drug absorption, distribution, metabolism, and excretion is known as
[A] pharmacotherapeutics
[B] pharmacodynamics
[C] pharmacokinetics
[D] pharmacy
[E] posology
Correct Answer: C.
Rationale: Pharmacokinetics is the study of how a drug interacts with the body, focusing on the processes of absorption,
distribution, metabolism, and excretion, which enables the understanding of a drug's concentration and effects over time.
This branch of pharmacology specifically explores the dynamic relationships between the drug and the body, making it the
correct term to describe the study of these complex interactions.
QUESTION 2
In order for drugs to cross the blood-brain barrier, they must be
[A] ionized
[B] positively charged
[C] water soluble
[D] lipid soluble
[E] negatively charged
Correct Answer: D.
Rationale: The blood-brain barrier is composed of lipid-rich cell membranes that selectively allow certain substances to
pass through. For drugs to cross this barrier, they must be lipid soluble, allowing them to dissolve in the lipid bilayer and
pass through, which is the key property that makes option D the correct answer.
QUESTION 3
First-pass metabolism refers to the metabolism of drugs in the
[A] kidney
[B] blood vessels
Confidential • Student Study Edition • Practice & Review Guide Page 3 of 44
, STUDENT STUDY & MASTERY EDITION PRACTICE & REVIEW GUIDE
[C] liver
[D] heart
[E] adipose tissue
Correct Answer: C.
Rationale: First-pass metabolism involves the initial breakdown of a drug by the liver after it is absorbed into the
bloodstream, which significantly affects its bioavailability. This process primarily occurs in the liver because it is responsible
for filtering the blood and metabolizing foreign substances, making it the primary site for first-pass metabolism.
QUESTION 4
The rate of drug absorption would be increased by which of the following?
[A] drug ionization
[B] water solubility
[C] positively charged drug
[D] negatively charged drug
[E] lipid solubility
Correct Answer: E.
Rationale: The rate of drug absorption is increased by lipid solubility because it allows the drug to easily pass through
non-polar biological membranes and into the bloodstream. This is in contrast to water-soluble drugs, which are more likely to
be trapped in the aqueous environment at the site of administration and therefore absorbed more slowly.
QUESTION 5
Which FDA pregnancy category would appear to be the safest for a developing fetus?
[A] Category A
[B] Category B
[C] Category C
[D] Category D
[E] Category X
Correct Answer: A.
Rationale: Category A is the safest for a developing fetus because it indicates that adequate and well-controlled studies in
pregnant women have not demonstrated a risk to the fetus, and the available data suggest that the drug can be used during
pregnancy without potential
harm. This category is assigned when there is no evidence of fetal harm in humans, making it the most favorable choice for
pregnant women.
