# SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS
## Questions 1–50
**Question 1**
A nurse is teaching a patient about a newly prescribed medication. The patient asks, "What does
it mean when the doctor says the drug has a long half-life?" Which response by the nurse is most
accurate?
A) "It means the drug will start working very quickly after you take it."
B) "It means the drug takes a long time to be eliminated from your body, so you may need fewer
doses per day."
C) "It means the drug is more likely to cause an allergic reaction."
D) "It means the drug is completely safe and has no side effects."
**Correct Answer: B**
**Rationale:** Half-life is the time required for the concentration of a drug in the body to
decrease by 50%. A long half-life means the drug is eliminated slowly, requiring less frequent
dosing to maintain therapeutic levels. Option A describes onset of action, not half-life. Option C
is incorrect as half-life does not correlate with allergic potential. Option D is incorrect because
all drugs have potential side effects regardless of half-life.

**Question 2**
The study of how a drug moves through the body, including absorption, distribution, metabolism,
and excretion, is known as:
A) Pharmacodynamics
B) Pharmacokinetics
,Page 3 of 236
C) Pharmacotherapeutics
D) Pharmacogenomics
**Correct Answer: B**
**Rationale:** Pharmacokinetics describes what the body does to the drug—its movement
through absorption, distribution, metabolism, and excretion (ADME). Pharmacodynamics
describes what the drug does to the body (mechanism of action). Pharmacotherapeutics is the
study of the therapeutic use of drugs. Pharmacogenomics is the study of how genetic variations
affect drug response.

**Question 3**
A medication that binds to a receptor and produces a response is called a(n):
A) Antagonist
B) Agonist
C) Partial agonist
D) Inverse agonist
**Correct Answer: B**
**Rationale:** An agonist binds to a receptor and activates it, producing a response. An
antagonist binds to a receptor but blocks it, producing no response. A partial agonist produces a
weaker response than a full agonist. An inverse agonist produces the opposite effect of an
agonist.

**Question 4**
A patient is prescribed a drug with a therapeutic index of 2. The nurse understands that this
means the drug:
A) Has a wide margin of safety
B) Has a narrow margin of safety and requires close monitoring
C) Is completely safe with no toxicity risk
D) Can be administered without monitoring serum levels
**Correct Answer: B**
**Rationale:** Therapeutic Index (TI) = TD50/ED50. A TI of 2 means the toxic dose is only
twice the effective dose—a very narrow margin of safety. Drugs with narrow therapeutic indices
include warfarin, digoxin, lithium, theophylline, and phenytoin, and they require close
therapeutic monitoring.

**Question 5**
A patient is receiving a medication that is highly protein-bound. The nurse understands that
which of the following is true about this medication?
A) It will have a rapid onset of action
B) It will have a longer duration of action
C) It will be excreted more quickly by the kidneys
D) It will be less likely to interact with other drugs
**Correct Answer: B**
