All of the following statements are true of cardiac emergencies except one. Which statement about cardiac emergencies is false?
  1. Myocardial infarction is the formal name for a heart attack
  2. The main concern with both angina pectoris and myocardial infarction is a lack of oxygenated blood to the heart
  3. Both myocardial infarction and angina pectoris result in damage to the cells of the heart
  4. Most cardiac arrest incidences are caused by myocardial infarctions
  5. Most myocardial infarctions do not result in cardiac arrest
Explanation
Answer: C - All of the statements above are true of cardiac emergencies except angina pectoris does not result in damage to the heart tissue. Although many people consider myocardial infarction and cardiac arrest the same thing, cardiac arrest occurs when a patient has no pulse, is unresponsive, and has no respirations. This can be caused by a heart attack, but most heart attacks do not result in full cardiac arrest. Cardiac arrest patients should receive CPR immediately.
