These patients have additional hemodynamic evidence of heart failure. Mean arterial pressure did not increase significantly in the patients with heart failure. Return to Item IX and make another selection. Ib No , this small weight loss would not alter the volume of distribution significantly. Return to Item I and try another response.
Item VIIb No .
The statement is true but does not explain the decreased heart rate. This effect of digitalis leads to an increased PR interval, or eventually to AV conduction block. Return to Item VII and make another choice. Decreased circulating plasma volume in only part of the explanation. Increased ejection fraction also contributes to the decrease in venous pressure because decreased ventricular chamber volume and diastolic pressure result in decreased venous filling pressure.
