A) Both pressures are low because the patient has increased fluid volume and may be septic from the pneumonia.
B) The CVP is low because the patient has increased fluid volume, and the high PAP indicates increased pressure in the lungs.
C) Both pressures are high, indicating that the patient has increased pressure in the lungs and a high fluid volume.
D) The CVP is high, indicating increased fluid volume, and the low PAP indicates impending heart failure.
