B: The right ventricle pumps the deoxygenated blood it has received from the right atrium to the lungs. The right atrium pumps deoxygenated blood from the body to the right ventricle. The left atrium pumps oxygenated blood from the lungs to the left ventricle. The left ventricle pumps oxygenated blood to the body. 2. Which lead is t...

Which type of atrioventricular (AV) block best describes this rhythm? - Second degree type II Your patient is in cardiac arrest and has been intubated. To assess CPR quality, which should you do? - Monitor the patient's PetCO2 Which facility is the most appropriate EMS destination for a patient with sudden cardiac arrest who achieved return a spontaneous circulation in the field? - Coronary reperfusion-capable medical center Which of the following signs is a likely indicator of cardiac arres...

How does COPD result in atrial fibrillation and predisposition to PEs? - COPD causes pulmonary hypertension, right ventricular hypertrophy, and right atrial enlargement. The right atrial enlargement causes stretching of the atrial tissue and frequently results in atrial dysrhythmias. SA blocks, second-degree AV block type I, and third-degree AV heart block at the level of the AV node would occur in _______________ occlusion - RCA (as seen in inferior wall MIs) There is (more/less) risk of b...

American Red Cross - ACLS FINAL EXAM A patient is in cardiac arrest. The cardiac monitor shows asystole. In addition to providing continuous high-quality CPR, what is the other priority intervention for this patient? - Answer - Administering epinephrine as early as possible A patient has experienced return of spontaneous circulation (ROSC) after cardiac arrest. The healthcare team is conducting a secondary assessment to determine the possible cause of the patient's cardiac arrest. Before the ...
