Consider the following client scenario:
John Grant, a 63 year old man has been diagnosed with bilateral knee osteoarthritis. His GP added Endone 5 mg pm but due to his worsening pain, mostly in his right knee, John was referred for a right total knee replacement and a plan to have the left knee done also, once he was fully recovered from the first operation. He has a history of angina, hypertension (HTN), hyperlipidemia, type 2 diabetes (T2DM), and depression. John is widower and owns a café, along with his eldest daughter. He previously worked 6 days / week however due to his painful knees he has reduced his work to light duties and office work 2 days/week and now worries about his daughter’s workload. John lives in his own home, which has six steps at the front, and is usually able to do all his own Activities of Daily Living (ADLs) and household work independently. His family visits regularly, and recently his son and daughter-in-law have been helping with the housework and cooking.
John has returned to your ward after having his total knee replacement surgery and you are the nurse taking over his post-operative cares.
