Acute Coronary Syndrome Questions with Correct Answers

The client with unstable angina has received education about the acute coronary syndrome. Which of the following indicates that he understood the teaching? 1. "This is a big warning, I must modify my lifestyle or risk having a heart attack in the next year." 2. "Angina is just a temporary interruption of blood flow to my heart." 3. "I need to tell my wife I've had a heart attack." 4. "Because this was temporary, I will not need to take any medications for my heart." - Answer 1. Among people who have unstable angina, 10% to 30% have a myocardial infarction (MI) within 1 year. Although angina pain is temporary, it reflects underlying coronary artery disease (CAD), which requires attention, including lifestyle modifications. Unstable angina reflects tissue ischemia, but infarction represents tissue necrosis. Clients with underlying CAD may need medications such as aspirin (ASA), lipid-lowering agents, antianginals, or antihypertensives. The nurse is caring for a group of clients who have sustained myocardial infarction (MI). The nurse observes the client with which type of MI most carefully for the development of left ventricular heart failure? 1. Inferior wall 2. Anterior wall 3. Lateral wall 4. Posterior wall - Answer 2. Owing to the large size of the anterior wall, the amount of tissue infarction may be large enough to decrease the force of contraction, leading to heart failure. with the inferior wall, the client is more likely to develop right ventricular MI. regarding clients with obstruction of the circumflex artery may experience a lateral wall or posterior wall MI and sinus dysrhythmias.
