The AED is MOST advantageous to the EMT-B becauseit delivers prompt defibrillation to patients with ventricular fibrillation.
Which of the following is a major difference between angina pectoris and acute myocardial infarction (AMI)?Anginal pain typically subsides with rest.
The descending aorta divides into the two iliac arteries at the level of theumbilicus
The purpose of defibrillation is tostop the chaotic, disorganized contraction of the cardiac cells
The EMT-B should use an automated external defibrillator (AED) on a child between 1 and 7 years of age ifpediatric pads are available and the child is in cardiac arrest
Which of the following statements regarding unstable angina is MOST correct?Unstable angina typically follows an unpredictable or unexpected pattern
Which of the following represents the MOST appropriate method of assisting a patient with his or her prescribed nitroglycerin tablet or spray?Administer the medication sublingually and allow it to dissolve or absorb.
After assisting your patient with his or her nitroglycerin, you shouldreassess the blood pressure within 5 minutes to detect hypotension.
When would it be MOST appropriate for a patient to take nitroglycerin?Chest pain that does not immediately subside with rest
Immediate transport of a patient with a suspected myocardial infarction is MOST important becausethe patient may be eligible to receive thrombolytic therapy.
Ventricular tachycardia causes hypotension becausethe left ventricle does not adequately fill with blood.
Major risk factors for a myocardial infarction include all of the following, EXCEPThypoglycemia
Narrowing of the coronary arteries due to a buildup of fatty deposits is calledatherosclerosis
Common signs and symptoms of cardiac compromise include all of the following, EXCEPTpain exacerbated by breathing

Upon arrival at the scene, the patient's wife tells you that he complained of chest pain the day before, but would not allow her to call EMS. The patient is semiconscious, has rapid and shallow respirations, and has a thready pulse. You shouldbegin ventilatory assistance
