Exam 2: Cardiac Practice Questions NCLEXWhich of the following actions is the first priority of care for a pt exhibiting signs & symptoms of coronary artery disease? 1. Decrease anxiety 2. Enhance myocardial oxygenation 3. Administer sublingual nitroglycerin 4. Educate the pt about his symptoms - correct answer 2. Enhancing myocardial oxygenation is always the first priority when a pt exhibits signs or symptoms of cardiac compromise. W/out adequate oxygenation, the myocardium suffers damage. Sublingual nitroglycerin is administered to treat acute angina, but administration isn't the first priority. Although educating the pt & decreasing anxiety are important in care delivery, neither are priorities when a pt is compromised.

Which of the following is the most common symptom of myocardial infarction (MI)? 1. Chest pain 2. Dyspnea 3. Edema 4. Palpitations - correct answer 1. The most common symptom of an MI is chest pain, resulting from deprivation of oxygen to the heart. Dyspnea is the second most common symptom, related to an increase in the metabolic needs of the body during an MI. Edema is a later sign of heart failure, often seen after an MI. Palpitations may result from reduced cardiac output, producing arrhythmias.
