I have a 95yrs old female patient with cva (only Hemiparlysis with no dysphagia), htn and renal insufficiency. She is urinary and bowel inciontinent because of the immobility. She also has a past medical history of colon resection and pvd.

I have to write 4 nursing diagnoses which i tried but i am not sure -

1. P - fluid volume imbalance

E- renal insufficiency ( because of the patient lab values high BUN - 43 normal range is 8-21 and high Creatinine - 1.5 normal range is 0.6-1.1)

S - Renal failure, monitor for confusion, dryskin.

2. P - fall risk

E- because of poor vision, faitgue, ineffective breathing pattern

S- non ambulatory,complains when she walk,need assistance during ambulation.
