My sister was induced for labor 2 days ago and she was sent home from the hospital with a healthy diagnosis for herself and the baby. This is her second child, in which she underwent toxcimia with the first pregnancy and she had lots of extra water weight. She is 21 years old, her height is 5'7 and probably weighs about 185 lbs. With both pregnancies she was given an epidural. She does not smoke, drink alcohol, or use any other substances. Today is her first morning at home and she has swollen legs and feet and directly after noticing so she had a nose bleed. What are these symptoms the result of and what kinds of precautions does she need to take?
