NIU NURS 308 Exam 2023 # 46 questions and
answers- 100% correct.
Pericardium - -double-walled membranous sac that encloses the heart and 2 layers of
the heart- the epicardium, myocardium, and endocardium
-endothelium - -blood vessel lining
tissues depend on blood supply and blood supply depends on endothelial cells
-path of blood through the heart - -
1.superior and inferior vena cava (from the body)
2.right atrium
3.tricuspid valve
4.right ventricle
5.pulmonary valve
6. Pulmonary arteries
7.pulmonary veins (from lungs)
8. Left atrium
9.mitral valve
10.left ventricle
11.aortic valve
12.descending aorta
-ABCDE's of cardiovascular prevention - -Aspirin
Blood pressure
Cholesterol
Diabetes
Excersize
-QRS wave on EKG - -ventricular depolarization (and atrial repolarization)
-P wave on EKG - -atrial depolarization (atrial contraction)
-T wave on EKG - -ventricular repolarization
-PR on EKG - -measure of time from onset of atrial activation to onset of ventricular
activation
-effect of activation of sympathetic nervous system on myocardial contraction, HR,
cardiac conduction, and intranodal conduction time - -increase strength of myocardial
contraction, increase HR, increased caridiac conduction, speed intranodal conduction
time
-which area of the electrical conduction system heart is responsible for controlling
electricity (setting pace and rate) - -SA node
