The left atrium can also enlarge but mainly causes left ventricular hypertrophy. The right ventricle will remain normal for a period of time. That's why LHF happens first then leads to RHF. Chronic mitral stenosis will cause enlargement in which area? Left atria hypertrophy. In pt with Mitral va...

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...

PCCN Exam Review questions & Answers, VERIFIED/ 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.
