A patient admitted with sepsis has a pulmonary artery catheter placed that also measures 
SvO2. During a routine assessment, the nurse notes that the patient's SvO2 is 56%. The nurse 
knows that this indicates:oxygen supply is not equal to demand. 
Which hemodynamic changes are associated with mitral stenosis?Elevated left atrial 
pressure, pulmonary artery occlusive pressure, and pulmonary artery diastolic pressure; 
normal left ventricular end-diastolic pressure

Which of the following would be the earliest auscultatory finding in left ventricular 
failure (LVF)? 
A. Crackles 
B. S3 
C. Murmur of mitral regurgitation 
D. Pericardial friction rub 
Ans: B. S3 
LVF would be the most subtle because early changes are usually subtle changes. 
Choose "S3."

Tx to decrease preload - -Diuretics 
-Dilators (nitrates, nitroprusside, morphine) 
Define preload - -Preload is the volume/pressure in the ventricle at the end of DIASTOLE after the 
AV valves close, just prior to ejection 
-As preload increases, SV and CO will increase up to a point 
-Too high of a preload may lead to heart failure 
-Preload will seldom be elevate if the heart is without disease and there are no metabolic abnormalities 
Cardiac output equation - CO = HR x SV 
Components of str...

What is cardiac tamponade? 
Fluid in the pericardial sac causing decreasing preload. This decreases SV and ultimately CO. 
Effects of Hyper/Hypokalemia and calcemia on EKG 
Hypokalemia causes U waves 
Hyperkalemia causes peaked T waves 
Normal BP? 
90-120/60-80 
Normal HR? 
60-100 bpm 
Normal CO? 
4-8 L/min 
Normal SVR? 
800-1,200 dynes/seconds 
Normal PVR? 
37-250 dynes/sec/cm5 
Normal SVo2?
