PRACTICE EXAM LATEST VERSION QUESTIONS AND ANSWERS
- UPDATED 2026 (GRADED A+)
Subject: Nursing Pharmacology and Medication Administration
Subtopic: Advanced Pharmacology, Clinical Judgment, and Medication Safety
Question 1: A nurse is administering intravenous vancomycin to a client who suddenly develops flushing,
hypotension, and pruritus of the upper body. Which adverse reaction should the nurse suspect?
A) Stevens-Johnson syndrome
B) Red man syndrome
C) Anaphylactic shock
D) Neuroleptic malignant syndrome exclusively
Correct Answer: B) - Red man syndrome
Rationale: Rapid infusion of vancomycin can trigger histamine release, causing flushing, hypotension,
and pruritus known as red man syndrome. Slowing the infusion rate and administering antihistamines
may reduce symptoms.
Question 2: A client receiving digoxin therapy reports nausea, blurred vision, and seeing yellow halos
around lights. Which action should the nurse take first?
A) Administer the next dose with food
B) Hold the medication and assess apical pulse
C) Encourage increased potassium restriction
D) Administer naloxone immediately exclusively
Correct Answer: B) - Hold the medication and assess apical pulse
Rationale: These findings suggest digoxin toxicity. The nurse should withhold the medication, assess
cardiac status, and notify the provider. Hypokalemia increases digoxin toxicity risk.
Question 3: A nurse is preparing to administer insulin glargine. Which characteristic of this medication
should the nurse recognize?
A) It peaks within one hour
B) It should be mixed with regular insulin
C) It provides long-acting basal insulin coverage
D) It is administered intravenously during emergencies exclusively
Correct Answer: C) - It provides long-acting basal insulin coverage
,Rationale: Insulin glargine is a long-acting insulin that provides steady basal glucose control with
minimal peak effect and should not be mixed with other insulins.
Question 4: A client receiving warfarin therapy asks why routine INR monitoring is necessary. Which
response by the nurse is most appropriate?
A) “It measures kidney function during therapy.”
B) “It helps evaluate your blood’s clotting tendency.”
C) “It determines blood glucose control.”
D) “It identifies liver enzyme production exclusively.”
Correct Answer: B) - “It helps evaluate your blood’s clotting tendency.”
Rationale: INR monitoring evaluates the effectiveness and safety of warfarin therapy by measuring
clotting time and guiding dosage adjustments.
Question 5: A nurse is caring for a client receiving morphine sulfate intravenously. Which assessment
finding requires immediate intervention?
A) Respiratory rate of 8/min
B) Blood pressure of 138/82 mm Hg
C) Heart rate of 86/min
D) Pain rating reduced from 8/10 to 4/10 exclusively
Correct Answer: A) - Respiratory rate of 8/min
Rationale: Opioid-induced respiratory depression is a life-threatening adverse effect requiring immediate
assessment and possible naloxone administration.
Question 6: A nurse is administering furosemide to a client with heart failure. Which electrolyte
imbalance is most important for the nurse to monitor?
A) Hypernatremia
B) Hypokalemia
C) Hypermagnesemia
D) Hyperphosphatemia exclusively
Correct Answer: B) - Hypokalemia
Rationale: Furosemide is a loop diuretic that promotes potassium excretion, increasing the risk for
hypokalemia and cardiac dysrhythmias.
Question 7: A client receiving heparin therapy develops severe bleeding. Which medication should the
nurse prepare to administer?
, A) Vitamin K
B) Protamine sulfate
C) Naloxone
D) Acetylcysteine exclusively
Correct Answer: B) - Protamine sulfate
Rationale: Protamine sulfate reverses the anticoagulant effects of heparin by binding and neutralizing
the medication.
Question 8: A nurse is teaching a client prescribed nitroglycerin sublingual tablets for angina. Which
client statement indicates correct understanding?
A) “I should store the tablets in a moist bathroom cabinet.”
B) “I will call emergency services if chest pain persists after taking three doses.”
C) “I can swallow the tablet immediately with water.”
D) “I should take the medication only after chest pain completely resolves.”
Correct Answer: B) - “I will call emergency services if chest pain persists after taking three doses.”
Rationale: Persistent chest pain after three nitroglycerin doses given five minutes apart may indicate
myocardial infarction and requires emergency evaluation.
Question 9: A nurse is caring for a client receiving aminoglycoside antibiotics. Which adverse effect
should the nurse monitor most closely?
A) Ototoxicity
B) Hyperglycemia
C) Severe hypertension
D) Respiratory alkalosis exclusively
Correct Answer: A) - Ototoxicity
Rationale: Aminoglycosides can damage cranial nerve VIII, causing hearing loss, tinnitus, and balance
disturbances. Nephrotoxicity is another major concern.
Question 10: A client prescribed prednisone for long-term therapy should be monitored for which
adverse effect?
A) Hypoglycemia
B) Immunosuppression and hyperglycemia
C) Severe bradycardia
D) Increased bone density exclusively
Correct Answer: B) - Immunosuppression and hyperglycemia
