SECTION I: BASIC PHARMACOLOGY PRINCIPLES
1. A nurse is teaching a client about the pharmacokinetics of a newly
prescribed medication. Which statement correctly describes the
process of absorption?
A) The movement of the drug from the site of administration into the
bloodstream
B) The distribution of the drug to body tissues
C) The chemical alteration of the drug in the liver
D) The elimination of the drug from the body
Answer: A) The movement of the drug from the site of
administration into the bloodstream
Rationale: Absorption is the process by which a drug moves from its
site of administration into the bloodstream. Distribution is the transport
,3|Page
of the drug throughout the body. Metabolism (biotransformation) is the
chemical alteration of the drug, primarily in the liver. Excretion is the
elimination of the drug from the body, primarily through the kidneys .
2. A nurse is explaining the first-pass effect to a client. Which
statement accurately describes this phenomenon?
A) The drug is metabolized in the liver before reaching systemic
circulation
B) The drug is excreted unchanged by the kidneys
C) The drug is absorbed directly into the lymphatic system
D) The drug is bound to plasma proteins
Answer: A) The drug is metabolized in the liver before reaching
systemic circulation
Rationale: The first-pass effect occurs when orally administered drugs
are absorbed from the GI tract and transported to the liver via the portal
circulation, where they may be metabolized before reaching systemic
circulation. This can significantly reduce the bioavailability of the drug.
Drugs with high first-pass metabolism may require higher oral doses or
alternative routes (IV, sublingual) .
3. A client asks the nurse why one medication is prescribed to be
taken with food while another is taken on an empty stomach. Which
response by the nurse is most accurate?
A) "Food always decreases drug absorption, so it doesn't matter"
B) "Food can affect the absorption and bioavailability of some
medications"
, 4|Page
C) "Medications should always be taken on an empty stomach"
D) "Food only affects liquid medications"
Answer: B) "Food can affect the absorption and bioavailability of
some medications"
Rationale: Food can affect drug absorption in various ways: it may
delay absorption, increase or decrease the amount absorbed, or affect the
rate of gastric emptying. Some medications are taken with food to
reduce GI irritation, while others are taken on an empty stomach to
enhance absorption. The nurse should educate clients about specific
instructions for each medication .
4. A nurse is reviewing medication administration with a client.
Which factor can affect the distribution of a drug in the body?
A) Protein binding
B) Blood flow to tissues
C) The pH of the environment
D) All of the above
Answer: D) All of the above
Rationale: Drug distribution is affected by multiple factors: protein
binding (only free, unbound drug is pharmacologically active), blood
flow to tissues (highly perfused organs receive drugs more quickly), and
pH (which affects ionization and lipid solubility). Other factors include
the blood-brain barrier and placental barrier .
5. A nurse is teaching a client about the half-life of a medication.
Which statement by the client indicates understanding?
