Exercise 5

Jerry, a 44-year-old male, arrived in the emergency room by ambulance after a bicycle accident. Examination revealed multiple fractures of the femur. He was otherwise healthy. The next day, he was taken to surgery to repair the fractures. After surgery, his hemoglobin was 7 g/dL. He refused blood transfusions and was discharged 6 days later. Jerry called his doctor within days of being discharged and told him that he had difficulty walking around the house on crutches because of shortness of breath and lack of stamina.
Consider why Jerry's hemoglobin decreased after surgery and how this could be related to his current symptoms.
Jerry's doctor gave him iron supplements to take every day.
Jerry was lethargic and pale and was having problems with activities of daily living.
Explain why Jerry could have these symptoms.
