I have a 76 year old male patient who had a left TKA one day ago and will have the right one done next week. He had a MI in 1991 and is stable on low dose aspirin and antihypertensives. He has arithitis. His albumin level was 3.3 and he recieved 500 ml Albumin 5% today. I came up with Acute Pain, Risk for Injury, and Impaired Physical Mobility. I am at a loss for the as related too and another dx. My instructor suggests only to do something with the albumin. His BMI is 24.9, so he's not "imbalanced nutrition less than" Any help would be appreciated.
