Question

4 50. year old female recieved trauma to the chest that caused severe impairment of the primary pacemaker cells of the heart Which of the following areas recieved the greatest damage? a. atrioventricular (AV) node b. sino atrial (SA) nade a. Bundle of His d. Ventricles ear-old male is diagnosed with left bundle branch block. Which Structures would not recieve an electrical impulse? a. Atrioventricular (AV) node b. sinoatrial (SA) Node a bundle of his do the left ventricle 9 A 54-year-old male is diagno D A nurse is discussing the pressure generated at the end of diastole. Which term is the nurse describing? a. pre load b. after load C. Systemic vascular resistance di total peripheral resistance W which principle should the nurse remember when planning nursing care for a patient with heart problem? As stated by the Frank- Starling law, there there is a direct relationship between the of the blood in the heart at the end of diastole and the of contraction during the next systole. a. pressure, duration b. volume, force c. viscosity, force do viscosity, duration

Answer 1

® Option B . The primary pacemakee is saino.atorial note and it receives greatest damage @ Option D - Left bundle branch bloche causes imponement of impulse to the left ventricle. ® Options B The pressure generated at the end of Si actoled with to eject blood out of heart

It describes the afteeload . . @ Option B - According to Frank-starling law, the higlice the volume of blood in ventricles leads to. hishee stedre volume re if volume is high ventricles contract with high pressure. . cs Scanned with CamScanner
