action?
A. Administer the medication with food
B. Monitor drug levels and assess for toxicity
C. Double the dose if the patient misses one dose
D. Encourage increased fluid intake
Correct Answer: B. Monitor drug levels and assess for toxicity
Rationale: Medications with a narrow therapeutic index require
close monitoring because small changes in drug levels can
cause toxicity or therapeutic failure.
2. A patient taking a medication reports difficulty breathing
and facial swelling. What should the nurse do first?
A. Document the reaction
B. Administer the next dose later
C. Treat as a possible allergic reaction and provide emergency
care
D. Encourage oral fluids
,Correct Answer: C. Treat as a possible allergic reaction and
provide emergency care
Rationale: Difficulty breathing and facial swelling indicate a
possible anaphylactic reaction requiring immediate
intervention.
3. Which organ is primarily responsible for metabolizing most
medications?
A. Heart
B. Liver
C. Lungs
D. Skin
Correct Answer: B. Liver
Rationale: The liver performs most drug metabolism through
enzyme systems such as cytochrome P450.
4. A nurse understands that a medication’s half-life refers to:
A. The time required for the medication to begin working
B. The time required for half of the drug to be eliminated from
the body
C. The maximum drug concentration reached
D. The amount of medication absorbed
Correct Answer: B. The time required for half of the drug to be
eliminated from the body
,Rationale: Half-life determines dosing intervals and how long a
drug remains active.
5. Which statement by a patient indicates understanding of
medication adherence?
A. “I will stop taking the medication when I feel better.”
B. “I will take my medication exactly as prescribed.”
C. “I can share my medication with family members.”

, 7. Which medication route provides the fastest onset of
action?
A. Oral

C. Intravenous
D. Subcutaneous
Correct Answer: C. Intravenous
Rationale: IV medications enter circulation immediately,
producing the fastest effect.
8. A nurse should assess renal function before administering
many medications because:
A. The kidneys produce medications
B. Many drugs are eliminated through the kidneys
C. The kidneys determine drug color
D. The kidneys increase absorption
Correct Answer: B. Many drugs are eliminated through the
kidneys
Rationale: Impaired renal function can cause medication
accumulation and toxicity.
9. Which finding suggests medication toxicity?
