MIDTERM EXAM - PART A: PHARMACOKINETICS & PHARMACODYNAMICS
Question 1
A nurse is teaching a patient about a newly prescribed medication. Which
statement accurately describes the process of absorption?
A. The movement of a drug from the site of administration into the bloodstream
B. The transport of a drug throughout the body via the circulatory system
C. The chemical alteration of a drug by the liver
D. The elimination of a drug from the body through the kidneys
Correct Answer: A
Rationale: Absorption is the process by which a drug moves from its site of
administration into the bloodstream. Distribution (B) refers to transport
throughout the body. Metabolism (C) occurs primarily in the liver. Excretion (D)
occurs through the kidneys and other routes.

,Question 2
A patient with liver cirrhosis is prescribed a medication that undergoes extensive
first-pass metabolism. The nurse anticipates that the prescriber will:
A. Increase the oral dose
B. Decrease the oral dose
C. Administer the medication intravenously
D. Administer the medication subcutaneously
Correct Answer: C
Rationale: First-pass metabolism occurs in the liver. In patients with cirrhosis,
liver function is impaired. Administering the drug intravenously bypasses first-
pass metabolism, allowing a more predictable therapeutic effect. Increasing the
oral dose could lead to toxicity if some metabolism still occurs unpredictably.
Question 3
The half-life of a drug is 4 hours. Approximately how long will it take for the drug
to reach steady state?
A. 4 hours
B. 8 hours
C. 16 hours
D. 20 hours
Correct Answer: D (approximately 4-5 half-lives = 16-20 hours)
Rationale: Steady state is typically achieved after 4-5 half-lives. For a drug with a
4-hour half-life, steady state is reached in approximately 16-20 hours. This is
when drug elimination equals drug administration.

,Question 4
Which factor would increase the volume of distribution (Vd) of a medication?
A. High protein binding
B. Low lipid solubility
C. High lipid solubility
D. High ionization
Correct Answer: C
Rationale: High lipid solubility allows drugs to cross cell membranes and distribute
into tissues, increasing Vd. High protein binding decreases Vd because the drug
remains in the vascular compartment. Low lipid solubility and high ionization limit
distribution.
Question 5
A patient is receiving a medication that has a narrow therapeutic index. Which
action is most important for the nurse to perform?
A. Monitor serum drug levels regularly
B. Administer the drug with food
C. Split the dose into multiple administrations
D. Monitor blood pressure
Correct Answer: A
Rationale: Drugs with a narrow therapeutic index have a small margin between
therapeutic and toxic doses. Monitoring serum drug levels ensures the patient
remains within the therapeutic range. Examples include digoxin, lithium, and
warfarin.

, Question 6
The nurse understands that bioavailability refers to:
A. The amount of drug that reaches the systemic circulation
B. The rate at which a drug is metabolized
C. The binding of a drug to plasma proteins
D. The time required for a drug to produce an effect
Correct Answer: A
Rationale: Bioavailability is the fraction of an administered dose that reaches the
systemic circulation unchanged. It is 100% for IV administration. Metabolism and
excretion affect bioavailability, but the definition specifically refers to systemic
circulation.
Question 7
A patient with renal impairment is at highest risk for drug toxicity due to:
A. Decreased drug absorption
B. Decreased drug distribution
C. Decreased drug excretion
D. Increased drug metabolism
Correct Answer: C
Rationale: Renal impairment reduces glomerular filtration and tubular secretion,
leading to drug accumulation and increased risk of toxicity. Drug doses may need
to
be adjusted in patients with renal impairment.
