Cardiac 100% SOLUTI

Advanced Health Assessment - Cardiac 100% SOLUTION 2023//2024 Which two heart chambers are most anterior in the chest? A. Both atria B. Both ventricles C. The right atrium and ventricle D. The left atrium and ventricle - ANSWER ANS: C The most anterior surface of the heart is formed by the right ventricle. The heart is turned ventrally on its axis, putting its right side more forward. The left atrium is above the left ventricle, forming the most posterior aspect of the heart. The condition in which a patient's heart is either rotated or displaced to the right or is situated as a mirror image of the expected position is called: A. amyloidosis. B. coarctation. C. dextrocardia. D. situs inversus. - ANSWER ANS: C Dextrocardia occurs when the heart is displaced or rotated to the right or is a complete mirror image of the expected finding. Amyloidosis is a metabolic disorder marked by amyloid deposits in organs and tissues. Coarctation is the compression of the walls of a vessel such as an aortic coarctation. Situs inversus occurs when the heart and stomach are displaced to the right and the liver is located to the left. Heart position can vary depending on body habitus. In a short, stocky individual, you would expect the heart to be located: A. more to the right and hanging more vertically. B. more to the left and lying more horizontally. C. riding higher in the chest and pushed anteriorly. D. hanging lower in the chest and riding more vertically. - ANSWER ANS: B The position of the heart varies depending on body build, configuration of the chest, and level of the diaphragm. A tall, slender person's heart tends to hang vertically and is positioned centrally. A stocky, short person's heart tends to lie more to the left and more horizontally. Which cardiac structure is responsible for the heart's pumping action? A. Pericardium B. Epicardium C. Myocardium D. Endocardium - ANSWER ANS: C The myocardium is the thick muscular middle layer that is responsible for the pumping action of the heart. The pericardium is the tough, double-walled, fibrous sac that protects the heart. The epicardium is the thin outermost muscle layer that covers the heart and extends onto the great vessels. The endocardium
