NSG-316 Exam 3 questions and
answers graded A+
heart muscle that surrounds ventricles and atrium
Atria are thinner as they need to pump less strong - correct answer ✔✔Myocardium
external layer that protects heart from injury/infection - correct answer ✔✔pericardium
3 layered membrane that lines heart chambers - correct answer ✔✔endocardium
heart attack or stroke - correct answer ✔✔blockage of coronary arteries can lead to
increased pressure of cardiac overload
-pulm congestion
-inc amount of blood in pulm capillaries - correct answer ✔✔heart failure
dyspnea/SOB, pulmonary edema - correct answer ✔✔Left sided heart failure
blood back up in the periphery and will present with edema - correct answer ✔✔right sided
heart failure
abnormal enlargement of the heart due to over working to compensate for decreased function -
correct answer ✔✔cardiomegaly
