- In a cardiac cycle, the average value of arterial blood pressure is<br/>called () A: Systolic pressure B: Diastolic pressure C: Pulse pressure D: Mean arterial pressure E: Central venous pressure
- The pressure measured in either the arterial or the venous<br/>circulation when the heart has stopped long enough to allow the<br/>pressures to equalize is called the () A: hemodynamic pressure B: mean arterial pressure C: transmural pressure D: mean circulatory filling pressure E: hydrostatic pressure
- Where is the highest partial pressure of carbon dioxide in the body A: Venous blood B: capillary blood C: arterial blood D: interstitial fluid E: intracellular fluid
- The arterial blood pressure: A: The mean arterial pressure of a normal young adult averages about 100 mmHg. B: Depends solely on the cardiac output. C: Is the arithmetic average of the systolic and diastolic pressures. D: Is due to the vascular resistance of the capillaries.
- The mechanism of lower extremity edema in patients with right heart failure does not include: A: Increased capillary permeability B: Retention of sodium and water C: Systemic venous congestion D: Hypoproteinemia E: Increased capillary hydrostatic pressure
