1. A nurse practitioner explains pharmacokinetics to a patient. Which phase
involves drug breakdown by the liver?
• A. Absorption
• B. Distribution
• C. Metabolism
• D. Excretion
Correct answer: C. Metabolism (phase II) is the process by which the liver
biochemically transforms drugs for elimination from the body.
2. The therapeutic index measures:
• A. Safety margin
• B. Drug potency
• C. Half-life
• D. Bioavailability
Correct answer: A. The therapeutic index is the ratio of a drug's toxic dose to
its effective dose and is used as a measure of drug safety.
3. In elderly patients, reduced renal function primarily affects:
• A. Drug excretion
• B. Drug absorption
• C. Protein binding
, • D. Drug distribution
Correct answer: A. Age-related decline in renal function impairs the clearance
and excretion of many drugs, necessitating dose adjustments.
4. First-pass effect is avoided by:
• A. Sublingual administration
• B. Oral administration
• C. Intramuscular administration
• D. Intravenous administration
Correct answer: A. Sublingual administration allows the drug to be absorbed
directly into the systemic circulation, bypassing the hepatic first-pass
metabolism.
5. CYP450 enzymes are involved in:
• A. Gastrointestinal absorption
• B. Hepatic oxidation
• C. Plasma protein binding
• D. Renal filtration
Correct answer: B. Cytochrome P450 enzymes are a key part of the hepatic
system responsible for oxidizing and metabolizing many drugs.
6. A drug with high volume of distribution:
• A. Distributes to tissues
• B. Stays in plasma
• C. Rapidly excreted
• D. Poorly absorbed
Correct answer: A. A high volume of distribution indicates that the drug is
extensively distributed into body tissues and is not confined to the plasma.
7. Which physiologic mechanism explains a drug's increased metabolism
triggered by a disease process?
• A. Selectivity response
, • B. Pharmacokinetics
• C. Pharmacodynamics
• D. Pharmacotherapeutics
Correct answer: B. Pharmacokinetics describes drug movement and how it is
affected by disease, such as altered metabolism.
8. An older client is receiving a water-soluble drug at a dose higher than
average for a young adult. Which action should the nurse implement first?
• A. Obtain a prescription for lower medication dosages.
• B. Determine the drug's serum levels for toxicity.
• C. Start IV fluids to decrease the serum drug levels.
• D. Hold the next dosage and notify the health care provider.
Correct answer: B. Older adults have decreased total body water, leading to
higher concentrations of water-soluble drugs. Assessing serum levels for
toxicity is the priority.
9. Which assessment parameter is most helpful in evaluating the effectiveness
of mannitol given with cisplatin?
• A. Oral temperature
• B. Blood cultures
• C. Urine output
• D. Liver enzyme levels
Correct answer: C. Mannitol is an osmotic diuretic given to promote diuresis
and reduce the risk of cisplatin-induced nephrotoxicity. Urine output is the key
measure of effectiveness.
10. A 4-year-old child receiving chemotherapy for acute lymphocytic leukemia
requires monitoring for infection risk. Which lab result should be examined?
• A. Hemoglobin
• B. Platelet count
• C. White blood cell (WBC) count with differential
, • D. Erythrocyte sedimentation rate
Correct answer: C. The WBC count is the primary indicator of infection risk, as
chemotherapy-induced neutropenia predisposes patients to infection.
11. A 7-year-old (25 kg) with community-acquired pneumonia is prescribed
high-dose amoxicillin (90 mg/kg/day divided BID x 7 days). Calculate the mg
per single dose.
• A. 1,125 mg
• B. 2,250 mg
• C. 562.5 mg
• D. 900 mg
Correct answer: A. 25 kg × 90 mg/kg/day = 2,250 mg/day ÷ 2 doses = 1,125
mg per dose.
12. Which vaccine is specifically contraindicated in a child with a history of
severe anaphylaxis to neomycin?
• A. MMR
• B. DTaP
• C. IPV
• D. Varicella
Correct answer: A. The MMR (measles, mumps, rubella) vaccine contains
trace amounts of neomycin and is contraindicated in patients with a history of
severe anaphylaxis to it.
13. A 3-month-old (5 kg) needs treatment for pertussis with azithromycin (10
mg/kg/day x 5 days). What is the daily dose?
• A. 15 mg
• B. 50 mg
• C. 100 mg
• D. 25 mg
Correct answer: B. 5 kg × 10 mg/kg/day = 50 mg daily.
