Myocardial Infarction Med-Surg

How does nitroglycerin decrease pain in a myocardial infarction (MI)?

• It reduces myocardial oxygen demand by lowering HR, BP, and cardiac contractility

• It promotes coronary artery vasodilation and reduces preload and afterload

• It functions as an analgesic, reduces cardiac contractility, and decreases HR

• It prevents ventricular remodeling and slows the progression of heart failure

Which of the following indicates a need for more teaching with a client at risk for sudden cardiac death (SCD)?

• “If my doctor sees v-tach and v-fib on my Holter monitor I will probably have to start taking amiodarone.”

• “I may have to go to the Cardiac Cath lab to determine the cause of my irregular heartbeat.”

• “Once I get treatment for my left ventricular dysfunction, my life should go back to normal.”

• “If I get an ICD, I may get shocked when my heart goes into v-tach, and it could be painful.”

What abnormality is noted on this ECG?

• NSTEMI

• 1st degree heart block

• Premature ventricular contractions (PVCs)

• STEMI

Which of the following dysrhythmias may lead to a life-threatening event after an MI?

• Premature ventricular contractions (PVCs)

• 1^st degree heart block

• Atrial fibrillation

Your client who just had an MI is preparing to discharge and wants to discuss the safety of the medications they were taking before hospitalization. Which medication would you be concerned about?

• Carvedilol

• Aspirin

• Prednisone

• Lisinopril
