Extract:
Question 1 of 5
A nurse on an oncology unit is preparing to administer doxorubicin to a client who has breast cancer. Prior to beginning the infusion, the nurse verifies the client's current cumulative lifetime dose of the medication. For which of the following reasons is this verification necessary?
Correct Answer: C
Rationale: Excessive doxorubicin causes cardiomyopathy, a dose-dependent risk, requiring lifetime dose monitoring, unlike extravasation, urine color, or myelosuppression.
Question 2 of 5
A nurse is caring for a client who has atrial fibrillation and receives digoxin daily. Before administering this medication, which of the following actions should the nurse take?
Correct Answer: C
Rationale: Digoxin can cause bradycardia. Measuring the apical pulse for one minute ensures the heart rate is safe (above 60 bpm) before administration, unlike weighing, blood pressure, or snacks.
Question 3 of 5
A nurse is teaching a client who has angina pectoris about starting therapy with sublingual (SL) nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?
Correct Answer: B
Rationale: Sublingual nitroglycerin is taken at chest pain onset for rapid relief, not with water, every 15 minutes, or routinely after meals.
Question 4 of 5

Question 5 of 5
A nurse is teaching a client who has a new prescription for simvastatin. Which of the following instructions should the nurse include?
Correct Answer: B
