1. PHARMACOLOGY FOUNDATIONS AND MEDICATION SAFETY
Q1. Which route of medication administration generally produces
the most rapid systemic effect?
A) Intravenous
B) Oral
C) Subcutaneous
D) Topical
Correct Answer: A) Intravenous
Rationale: Intravenous administration delivers medication directly into the
bloodstream, producing the fastest systemic effect.
Q2. Which pharmacokinetic process describes movement of a
medication from the administration site into the bloodstream?
A) Distribution
B) Absorption
,C) Metabolism
D) Excretion
Correct Answer: B) Absorption
Rationale: Absorption is the movement of a drug from its administration
site into systemic circulation.
Q3. Which organ is primarily responsible for metabolism of many
medications?
A) Liver
B) Spleen
C) Pancreas
D) Thyroid
Correct Answer: A) Liver
Rationale: The liver contains enzyme systems that metabolize many
medications.
Q4. Which organ is primarily responsible for elimination of many
medications and their metabolites?
A) Kidney
B) Stomach
C) Gallbladder
D) Thyroid
Correct Answer: A) Kidney
Rationale: The kidneys eliminate many drugs and metabolites through
urine.
Q5. A medication has a long half-life. What does this mean?
A) It takes longer for the drug concentration to decrease by half
B) It is absorbed immediately
C) It cannot accumulate
D) It has no adverse effects
Correct Answer: A) It takes longer for the drug concentration to decrease by
half
Rationale: Half-life is the time required for the plasma concentration of a
drug to decrease by approximately 50%.
, Q6. Which patient is at greatest risk for medication accumulation?
A) Patient with severe renal impairment
B) Healthy young adult
C) Patient with normal liver and kidney function
D) Patient receiving a single topical dose
Correct Answer: A) Patient with severe renal impairment
Rationale: Reduced renal clearance can cause renally eliminated
medications to accumulate.
Q7. Which term describes the amount of drug required to produce a
desired effect?
A) Dose
B) Half-life
C) Clearance
D) Bioavailability
Correct Answer: A) Dose
Rationale: Dose refers to the quantity of medication administered to
produce a therapeutic response.
Q8. Which term describes the proportion of an administered drug
that reaches systemic circulation?
A) Bioavailability
B) Potency
C) Clearance
D) Distribution
Correct Answer: A) Bioavailability
Rationale: Bioavailability is the fraction of an administered dose that
reaches systemic circulation in active form.
Q9. Which medication error is most likely to occur when two drug
names look or sound alike?
A) Look-alike/sound-alike medication error
B) Therapeutic duplication
C) Drug tolerance
D) First-pass metabolism
Correct Answer: A) Look-alike/sound-alike medication error
