1. Pharmacokinetics
Which process describes the movement of a medication from the administration site into
systemic circulation?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Answer: B
Rationale: Absorption is the movement of a drug from its administration site into the
bloodstream.
2. Pharmacodynamics
Pharmacodynamics primarily describes:
A. How the kidneys eliminate medications
B. How medications are absorbed
C. What the drug does to the body
D. How medications are stored
Answer: C
Rationale: Pharmacodynamics concerns the physiologic and biochemical effects of drugs and
their mechanisms of action.
3. First-Pass Effect
Which route largely bypasses hepatic first-pass metabolism?
,A. Oral
B. Sublingual
C. Enteral
D. Oral capsule
Answer: B
Rationale: Sublingual medication is absorbed through the oral mucosa directly into systemic
circulation.
4. Drug Half-Life
A drug has a half-life of 10 hours. Approximately what percentage remains after 20 hours?
A. 75%
B. 50%
C. 25%
D. 10%
Answer: C
Rationale: After one half-life, 50% remains; after two half-lives, approximately 25% remains.
5. Loading Dose
The primary purpose of a loading dose is to:
A. Eliminate adverse effects
B. Rapidly achieve a therapeutic drug concentration
C. Prevent absorption
D. Reduce renal clearance
Answer: B
Rationale: A loading dose is used when a therapeutic concentration needs to be reached more
rapidly than would occur with maintenance doses alone.
6. Protein Binding
A medication is highly protein bound. A patient develops severe hypoalbuminemia. What can
happen?
A. Less free drug is available
B. More free drug may circulate
,C. The drug cannot be absorbed
D. The medication automatically becomes inactive
Answer: B
Rationale: Reduced albumin can increase the unbound fraction of highly protein-bound
medications, potentially increasing pharmacologic effects or toxicity.
7. Therapeutic Index
A medication with a narrow therapeutic index requires:
A. Minimal monitoring
B. Careful monitoring for therapeutic and toxic effects
C. Automatic dose escalation
D. Administration only intravenously
Answer: B
Rationale: A narrow therapeutic index means the difference between effective and toxic
concentrations is relatively small.
8. Renal Clearance
Which patient is at increased risk for accumulation of a medication primarily eliminated by the
kidneys?
A. Patient with significant renal impairment
B. Patient with normal renal function
C. Patient with increased appetite
D. Patient with seasonal allergies
Answer: A
Rationale: Reduced renal clearance can increase drug concentrations and toxicity.
9. Hepatic Metabolism
Which organ is responsible for the metabolism of many medications?
A. Liver
B. Spleen
C. Pancreas
D. Thyroid
Answer: A
, Rationale: The liver is a major site of drug metabolism.
10. CYP450 Interaction
A medication strongly inhibits a CYP450 enzyme responsible for metabolizing another drug.
What may happen to the second drug?
A. Its concentration may increase
B. Its concentration must decrease
C. It becomes an antibiotic
D. It is automatically excreted faster
Answer: A
Rationale: Enzyme inhibition can reduce metabolism of the affected drug and increase its
plasma concentration.
11. Medication Safety
Before administering a medication, the nurse should first verify:
A. The patient's room decoration
B. The medication order and patient identity
C. The patient's meal preference
D. The patient's visitor list
Answer: B
Rationale: Correct patient identification and verification of the medication order are
fundamental medication-safety steps.
12. Allergy
A patient reports a previous severe reaction to a medication. The same medication is
prescribed. What should the nurse do?
A. Administer it with food
B. Hold it and clarify the prescription
C. Give half the dose
D. Give it more slowly
Answer: B
Rationale: A documented severe allergy requires clarification before administration.
