The nurse is assisting in the care of a client experiencing an acute myocardial infarction (MI). Which medication would the nurse expect to be administered to help reduce myocardial oxygen demand?

  • A. Aspirin
  • B. Morphine
  • C. Atropine
  • D. Lidocaine
Correct Answer: B

Rationale: In the context of an acute myocardial infarction (MI), morphine is administered to relieve pain and reduce myocardial oxygen demand. By alleviating pain and anxiety, morphine helps reduce oxygen demand on the heart, which is beneficial in the setting of an MI. Aspirin, commonly used for its antiplatelet effects, helps inhibit platelet aggregation and is crucial in the management of MI to prevent further clot formation. Atropine is a medication used to treat symptomatic bradycardia by increasing heart rate, not commonly indicated in the management of acute MI. Lidocaine is used for ventricular dysrhythmias and is not typically given to reduce myocardial oxygen demand in an acute MI scenario.
