College
Q1. Which statement best defines the therapeutic effect of a medication?
A) An unintended harmful response
B) The maximum concentration reached in plasma
C) The process by which a medication is eliminated
D) The intended beneficial response produced by the medication
Correct Answer: D) The intended beneficial response produced by the medication
Rationale: A therapeutic effect is the desired clinical response for which a medication is
administered.
Q2. Which processes make up pharmacokinetics?
A) Receptor binding, tolerance, dependence, and toxicity
B) Diagnosis, prescription, administration, and evaluation
C) Potency, efficacy, selectivity, and affinity
D) Absorption, distribution, metabolism, and excretion
Correct Answer: D) Absorption, distribution, metabolism, and excretion
Rationale: Pharmacokinetics describes what the body does to a medication through
absorption, distribution, metabolism, and elimination.
Q3. Why may an orally administered drug have lower bioavailability than the same
medication given intravenously?
A) Oral medications never enter the systemic circulation
B) IV medications undergo more extensive hepatic metabolism
C) Some oral medication may be metabolized before reaching systemic circulation
D) Oral administration always prevents drug absorption
Correct Answer: C) Some oral medication may be metabolized before reaching systemic
circulation
Rationale: First-pass metabolism in the intestinal wall and liver can reduce the amount of
an orally administered drug that reaches systemic circulation.
Q4. What is the primary purpose of medication reconciliation?
A) Determine whether the patient likes the medication
B) Identify and resolve discrepancies between current and newly prescribed medications
,C) Eliminate all over-the-counter medications
D) Replace laboratory monitoring
Correct Answer: B) Identify and resolve discrepancies between current and newly
prescribed medications
Rationale: Medication reconciliation reduces medication errors by comparing
prescriptions with the patient's actual medication use during transitions of care.
Q5. Which practice is appropriate when administering a high-alert medication?
A) Skip dose calculations when the patient has previously received the drug
B) Follow required independent verification and safety procedures
C) Administer the medication without reviewing laboratory values
D) Use verbal confirmation from another patient
Correct Answer: B) Follow required independent verification and safety procedures
Rationale: High-alert medications have a greater potential to cause serious harm when
errors occur and require enhanced safeguards.
Q6. Which action best verifies a patient's identity before medication administration?
A) Use two approved patient identifiers
B) Ask only for the room number
C) Identify the patient by diagnosis
D) Confirm the medication with a family member only
Correct Answer: A) Use two approved patient identifiers
Rationale: Two approved identifiers reduce the risk of administering medication to the
wrong patient.
Q7. Which laboratory value is particularly important when a medication is primarily
eliminated through the kidneys?
A) Serum bilirubin
B) Renal-function measures such as creatinine and estimated filtration
C) Hemoglobin A1C only
D) Amylase
Correct Answer: B) Renal-function measures such as creatinine and estimated filtration
Rationale: Reduced kidney function can decrease drug elimination and increase
medication accumulation and toxicity.
, Q8. What does a medication's half-life describe?
A) The amount absorbed after one hour
B) The time until the first therapeutic response
C) The period required for complete elimination
D) The time required for the amount of drug in the body to decrease by approximately one-
half
Correct Answer: D) The time required for the amount of drug in the body to decrease by
approximately one-half
Rationale: Half-life helps determine dosing intervals and the time needed to approach
steady-state concentration.
Q9. Why are medication doses sometimes reduced in significant renal impairment?
A) Renal disease always increases medication metabolism
B) Impaired excretion can cause medication accumulation
C) Renal impairment prevents all medication absorption
D) Kidney dysfunction always lowers drug potency
Correct Answer: B) Impaired excretion can cause medication accumulation
Rationale: Medications or active metabolites eliminated by the kidneys may accumulate
when renal clearance declines.
Q10. Which route generally provides the most rapid systemic drug effect?
A) Oral
B) Subcutaneous
C) Transdermal
D) Intravenous
Correct Answer: D) Intravenous
Rationale: IV administration places medication directly into the circulation and eliminates
the absorption step.
Q11. How does a pharmacologic antagonist generally act?
A) It binds to a receptor and prevents or reduces activation by an agonist
B) It always increases receptor activity
C) It accelerates renal excretion of every medication
D) It permanently destroys the receptor
Correct Answer: A) It binds to a receptor and prevents or reduces activation by an agonist
