General Pharmacology & Medication Safety
1. Which pharmacokinetic process describes movement of a drug
from the site of administration into systemic circulation?
A. Metabolism
B. Distribution
C. Absorption
D. Excretion
Answer: C. Absorption
Absorption is the movement of a drug from its administration site
into the bloodstream.
2. Which organ is primarily responsible for drug metabolism?
A. Kidney
B. Liver
C. Heart
D. Pancreas
Answer: B. Liver
The liver contains enzymes, particularly the cytochrome P450 system,
that metabolize many medications.
,3. A nurse is explaining drug half-life to a patient. Which statement
is correct?
A. It is the time required for a drug to begin working.
B. It is the time required for half of the drug to be eliminated from
the body.
C. It is the time required for complete drug elimination.
D. It is the time required for a drug to reach peak concentration.
Answer: B. It is the time required for half of the drug to be
eliminated from the body.
Half-life is the time required for the plasma concentration of a drug
to decrease by 50%.
4. Which route generally provides 100% bioavailability?
A. Oral
B. Subcutaneous
C. Intravenous
D. Intramuscular
Answer: C. Intravenous
An IV medication enters systemic circulation directly, resulting in
essentially complete bioavailability.
5. Which laboratory value is most important to assess before
administering many renally excreted medications?
A. Serum creatinine
B. Hemoglobin
C. Platelet count
D. Serum amylase
Answer: A. Serum creatinine
,Serum creatinine helps assess renal function and can indicate
whether medication dosing may need adjustment.
6. What is the primary purpose of a loading dose?
A. Prevent drug absorption
B. Achieve therapeutic drug levels rapidly
C. Decrease medication toxicity
D. Extend the drug's half-life
Answer: B. Achieve therapeutic drug levels rapidly
A loading dose is larger than the maintenance dose and is used to
reach a therapeutic concentration more quickly.
7. A medication has a narrow therapeutic index. What does this
mean?
A. The medication has a very wide safety margin.
B. Small differences between therapeutic and toxic concentrations
exist.
C. The medication is poorly absorbed.
D. The medication cannot cause adverse effects.
Answer: B. Small differences between therapeutic and toxic
concentrations exist.
Drugs with narrow therapeutic ranges require careful dosing and
monitoring.
8. Which action is most appropriate when administering a high-
alert medication?
A. Skip the medication history
B. Use independent verification when required
, C. Administer it without checking the dose
D. Ask the patient to determine the dose
Answer: B. Use independent verification when required
Independent double-checks are used for selected high-alert
medications to reduce serious medication errors.
9. Which abbreviation should the nurse avoid because it can be
misinterpreted?
A. mL
B. PO
C. U
D. mg
Answer: C. U
The abbreviation "U" for units can be misread as a zero or another
character; "units" should be written out.
10. Which patient identifier is appropriate before medication
administration?
A. Room number only
B. Diagnosis only
C. Two approved patient identifiers
D. Patient's appearance
Answer: C. Two approved patient identifiers
Using two identifiers helps ensure the medication is given to the
correct patient.
