Choices: A. 'I will use a soft-bristle toothbrush to prevent bleeding.'
B. 'I will avoid eating large amounts of green, leafy vegetables.'
C. 'I will take aspirin if I have a headache.'
D. 'I will have my blood tested regularly.'
Answer: C
Rationale: Aspirin is an antiplatelet agent that can increase the risk of bleeding when taken with warfarin. Patients on
warfarin should be advised to avoid aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs).
Question 2: A client with a history of heart failure is prescribed furosemide (Lasix). The nurse should monitor the client
for which of the following adverse effects?
Choices: A. Hyperkalemia
B. Hypertension
C. Hypokalemia
D. Hypernatremia
Answer: C
Rationale: Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia. Monitoring of
serum potassium levels is essential.
Question 3: A nurse is preparing to administer morphine 4 mg IV to a client. Available is morphine 10 mg/mL. How many
mL should the nurse administer?
Choices: A. 0.2 mL
B. 0.4 mL
C. 0.5 mL
D. 0.6 mL
Answer: B
,Rationale: To calculate the volume: (Desired dose / Concentration) = (4 mg / 10 mg/mL) = 0.4 mL.
Question 4: A client is prescribed digoxin (Lanoxin). The nurse should recognize which of the following as a sign of
digoxin toxicity?
Choices: A. Increased appetite
B. Blurred vision
C. Hypertension
D. Diarrhea

values should the nurse monitor to evaluate the effectiveness of the heparin?
Choices: A. Prothrombin time (PT)
B. Hematocrit (Hct)
C. Platelet count
D. Activated partial thromboplastin time (aPTT)
Answer: D
Rationale: Heparin's effectiveness is monitored using the aPTT. Heparin prolongs the aPTT, and therapeutic levels are
typically 1.5 to 2.5 times the control value.
Question 6: A nurse is providing education to a client who is prescribed warfarin (Coumadin). Which of the following
statements by the client indicates a need for further teaching?
