SECTION 1: PHARMACOKINETICS, PHARMACODYNAMICS & MEDICATION
ADMINISTRATION (Questions 1–30)
1. A nurse is teaching a client about a newly prescribed medication. Which
statement by the client indicates an understanding of pharmacokinetics?
A. "The medication will start working immediately after I take it."
B. "My body will absorb, distribute, metabolize, and eliminate the medication."
C. "The medication will only affect the area where I apply it."
D. "I will not experience any side effects from this medication."
Valid answer: B
Rationale: Pharmacokinetics refers to how the body processes a medication
through absorption, distribution, metabolism, and excretion (ADME). Option A
describes onset of action, not pharmacokinetics. Option C describes local effect,
and Option D is incorrect as all medications have potential side effects.
2. A nurse is reviewing factors that affect drug absorption. Which factor can
significantly affect drug absorption?
A. Liver function
B. Kidney function
C. Gastric pH and presence of food
D. Protein binding
Valid answer: C
, 2
Rationale: Gastric pH and the presence of food in the stomach can significantly
affect drug absorption. Liver function affects metabolism, kidney function affects
excretion, and protein binding affects distribution.
3. A nurse is caring for a client who has a medication with a narrow therapeutic
index. Which action should the nurse take?
A. Monitor serum drug levels closely
B. Administer the medication with food
C. Double the dose if the client misses a dose
D. Discontinue the medication if side effects occur
Valid answer: A
Rationale: Medications with a narrow therapeutic index (e.g., digoxin, lithium,
warfarin, phenytoin) require close monitoring of serum drug levels because the
difference between therapeutic and toxic doses is small.
4. A nurse is preparing to administer a medication that undergoes first-pass
metabolism. Which route of administration would AVOID first-pass metabolism?
A. Oral
B. Sublingual
C. Rectal
D. Intravenous
Valid answer: D
Rationale: First-pass metabolism occurs when a medication is absorbed from the
GI tract and metabolized by the liver before reaching systemic circulation.
Intravenous administration bypasses this entirely, as the drug enters the
bloodstream directly. Sublingual and rectal routes partially avoid first-pass
metabolism but not completely.

5. A nurse is reviewing the five rights of medication administration. Which of the
following is included in the five rights?
A. Right room
B. Right time
C. Right diet
D. Right family member
Valid answer: B
Rationale: The five rights of medication administration are: right client, right
medication, right dose, right route, and right time. Some references include right
documentation and right reason as additional rights.
6. A nurse is preparing to administer an enteric-coated medication. Which action
should the nurse take?
A. Crush the tablet for easier administration
B. Administer the tablet whole without crushing
C. Dissolve the tablet in water before administration
D. Split the tablet in half for a smaller dose
Valid answer: B
Rationale: Enteric-coated medications should be administered whole without
crushing or chewing. The coating protects the medication from gastric acid and
prevents gastric irritation. Crushing or dissolving destroys the protective coating.
7. A nurse is teaching a client about drug half-life. Which statement accurately
describes half-life?
A. The time it takes for a drug to reach its peak effect
B. The time it takes for the body to eliminate half of the drug
C. The time it takes for a drug to be completely eliminated
D. The time it takes for a drug to be absorbed
, 4
Valid answer: B
Rationale: Half-life is the time required for the body to eliminate half of the drug.
It determines dosing frequency and time to reach steady state. Drugs with a short
half-life require more frequent dosing.
8. A nurse is administering a medication that is highly protein-bound. Which
client condition would increase the risk of toxicity?
A. Dehydration
B. Malnutrition with low serum albumin
C. Hypertension
D. Diabetes mellitus
Valid answer: B
Rationale: Highly protein-bound medications are primarily bound to albumin.
Clients with low serum albumin (malnutrition, liver disease, nephrotic syndrome)
have fewer protein binding sites, resulting in higher free drug levels and increased
risk of toxicity.
9. A nurse is preparing to administer a liquid medication. Which action should
the nurse take to ensure accurate dosing?
A. Use a household teaspoon for measurement
B. Use a calibrated medication syringe or cup
C. Estimate the dose based on the client's size
D. Pour the medication directly into the client's mouth
Valid answer: B
Rationale: A calibrated medication syringe or cup should be used to ensure
accurate dosing. Household teaspoons are not standardized and can lead to
dosing errors.
