Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) - A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known as coronar...

PCCN Exam Review questions & Answers, graded A+ The nurse observes that the patient's jugular veins distend in the semi-upright position to more than 5 cm above the sternal angle. This is an indication of: - -fluid volume overload. what is normal Pulmonary artery occlusion pressure (PAOP)? - -5-12 mmHg The resistance against which the left ventricle must pump to eject its volume is: - -systemic vascular resistance. When the tricuspid valve is open, central venous pressure reflects the...
