Patient states she has a 30-pound weight gain in 6 weeks and is now requiring 3 pillows to sleep. On physical exam the patient is a well-developed, well-nourished female exhibiting signs of respiratory distress with use of accessory muscles. Blood pressure 150/80, pulse 105, respirations 28 and labored. Body weight 89 kg. HEENT was unremarkable. Cardiac exam had an S1, S2 and S3 without S4 or murmur. Respiratory exam was positive for bilateral rales 1/2 up both lung fields. Abdomen was enlarged with a positive fluid wave. Lower extremities were remarkable for 3+ pitting edema.
