When assessing the patient with pulmonary edema, which pulmonary capillary wedge pressure does the nurse anticipate?
A) <10 mmHg
B) 10-14 mmHg
C) 14-18 mmHg
D) > 18 mmHg
D) > 18 mmHg
Explanation: A) An elevated pulmonary wedge pressure that is greater than 18 mmHg indicates an increased left atrial pressure associated with heart failure and an increased pulmonary capillary permeability, which means that there is a greater hydrostatic pressure for filtration of fluid.
B) An elevated pulmonary wedge pressure that is greater than 18 mmHg indicates an increased left atrial pressure associated with heart failure and an increased pulmonary capillary permeability, which means that there is a greater hydrostatic pressure for filtration of fluid.
C) An elevated pulmonary wedge pressure that is greater than 18 mmHg indicates an increased left atrial pressure associated with heart failure and an increased pulmonary capillary permeability, which means that there is a greater hydrostatic pressure for filtration of fluid.
D) An elevated pulmonary wedge pressure that is greater than 18 mmHg indicates an increased left atrial pressure associated with heart failure and an increased pulmonary capillary permeability, which means that there is a greater hydrostatic pressure for filtration of fluid.
