Section 1: VATI Pharmacology Proctored Exam
Q1: A nurse is caring for a client receiving digoxin 0.25 mg daily. Which laboratory value
requires immediate notification to the healthcare provider?
A. Potassium 4.2 mEq/L
B. Digoxin level 1.8 ng/mL
C. Potassium 2.8 mEq/L [CORRECT]
D. Creatinine 1.0 mg/dL
Correct Answer: C
Rationale: Hypokalemia increases the risk of digoxin toxicity. A potassium level of 2.8 mEq/L is
critically low and predisposes the client to dangerous cardiac dysrhythmias when taking digoxin.
Q2: Case Study: A 68-year-old client with heart failure is prescribed furosemide 40 mg IV twice
daily, lisinopril 10 mg daily, and spironolactone 25 mg daily.
Q2a: Which assessment finding requires immediate intervention by the nurse?
A. Blood pressure 138/88 mmHg
B. Urine output 800 mL in 8 hours
C. Serum potassium 5.8 mEq/L [CORRECT]
D. Weight gain of 1 kg over 3 days
Correct Answer: C
Rationale: The combination of ACE inhibitor (lisinopril) and potassium-sparing diuretic
(spironolactone) increases hyperkalemia risk. A potassium level of 5.8 mEq/L requires
immediate intervention to prevent life-threatening cardiac dysrhythmias.
Q3: A client receiving heparin therapy has an aPTT of 90 seconds (control 30 seconds). What is
the nurse's priority action?
A. Continue current heparin infusion rate
B. Reduce heparin infusion rate per protocol [CORRECT]
,2
C. Administer protamine sulfate immediately
D. Obtain a STAT PT/INR
Correct Answer: B
Rationale: An aPTT of 90 seconds represents therapeutic prolongation (usually 1.5-2.5 times
control). The nurse should reduce the infusion per protocol rather than give full reversal with
protamine unless severe bleeding occurs.
Q4: A nurse is teaching a client about warfarin therapy. Which client statement indicates
understanding of dietary considerations?
A. "I will avoid all green vegetables completely."
B. "I should maintain consistent vitamin K intake." [CORRECT]
C. "I can eat spinach freely since it is healthy."
D. "I will double my dose if I eat a salad."
Correct Answer: B
Rationale: Consistent vitamin K intake allows for stable warfarin dosing. Clients should not
avoid vitamin K foods but rather maintain consistent consumption so INR remains stable.
Q5: Case Study: A client with atrial fibrillation is prescribed dabigatran 150 mg twice daily.
Q5a: Which laboratory monitoring is essential for this client?
A. aPTT every 2 weeks
B. CBC annually
C. Renal function tests periodically [CORRECT]
D. Liver function tests monthly
Correct Answer: C
Rationale: Dabigatran is primarily renally excreted. Renal function monitoring is essential to
adjust dosing and prevent accumulation, particularly in older adults or those with declining
kidney function.
Q6: A client with angina is prescribed nitroglycerin sublingual tablets. Which instruction should
the nurse provide?
A. "Swallow the tablet with water for faster absorption."
B. "Take up to 5 tablets at 5-minute intervals for chest pain." [CORRECT]
,3
C. "Store the medication in the bathroom medicine cabinet."
D. "Chew the tablet thoroughly before swallowing."
Correct Answer: B
Rationale: For acute angina, clients may take up to 3 tablets at 5-minute intervals (not 5). If pain
persists after 3 doses, emergency services should be called. Sublingual administration allows
rapid absorption.
Q7: A nurse is monitoring a client receiving dopamine for cardiogenic shock. Which finding
indicates the medication is effective?
A. Urine output 20 mL/hour
B. Heart rate 110 beats/minute
C. Blood pressure 92/60 mmHg improving to 108/72 mmHg [CORRECT]
D. Central venous pressure 2 cmH2O
Correct Answer: C
Rationale: Dopamine at moderate doses improves cardiac output and blood pressure. An
improving blood pressure from hypotensive to near-normal range indicates therapeutic
effectiveness.
Q8: Case Study: A client with type 2 diabetes is prescribed metformin 1000 mg twice daily,
glipizide 5 mg daily, and insulin glargine 20 units at bedtime.
Q8a: The nurse should instruct the client to withhold which medication before a scheduled CT
scan with contrast?
A. Glipizide
B. Insulin glargine
C. Metformin [CORRECT]
D. All oral medications
Correct Answer: C
Rationale: Metformin should be withheld 48 hours before and after iodinated contrast studies due
to risk of lactic acidosis from potential acute kidney injury caused by contrast dye.
Q9: A client with hyperthyroidism is prescribed methimazole. Which assessment finding
indicates a therapeutic response?
A. Increased appetite
, 4
B. Weight gain of 3 pounds in 2 weeks [CORRECT]
C. Resting tremor present
D. Heart rate 110 beats/minute
Correct Answer: B
Rationale: Weight gain indicates reduced metabolic rate from successful antithyroid therapy.
Other signs of therapeutic response include decreased heart rate, reduced tremor, and normalized
appetite.
Q10: A nurse is caring for a client receiving levothyroxine 125 mcg daily. When is the optimal
time for administration?
A. At bedtime with snack
B. With breakfast and coffee
C. 30-60 minutes before breakfast on empty stomach [CORRECT]
D. With lunch for better absorption
Correct Answer: C
Rationale: Levothyroxine absorption is optimized when taken on an empty stomach 30-60
minutes before breakfast. Food, coffee, calcium, and iron interfere with absorption.
Q11: Case Study: A client with Cushing's disease is prescribed ketoconazole to reduce cortisol
production.
Q11a: Which finding requires immediate notification to the healthcare provider?
A. Nausea after taking medication
B. Dark urine and yellow sclera [CORRECT]
C. Mild headache
D. Drowsiness in the evening
Correct Answer: B
Rationale: Ketoconazole can cause hepatotoxicity. Dark urine and jaundice (yellow sclera)
indicate liver dysfunction requiring immediate medical evaluation.
Q12: A client with Parkinson's disease is prescribed levodopa-carbidopa. Which dietary
instruction is most important?
A. "Take the medication with high-protein meals for energy."
