Question

A nurse is caring for a client who is three hours post op from open abdominal surgery. during routine assessment, the nurse notes the previously stable client now appears anxious, apprehensive, and has a blood pressure of 90/56. what does the nurse consider is the most likely cause of the client's change in condition?

Answer 1

Anxious and apprehensive are signs that the patient doesn't have enough blood to his brain. The cause probably is the low blood pressure. 
Open abdominal surgery is a major surgery so it should have a high risk of bleeding. Bleeding in abdominal space is dangerous because it was not visible and space is massive. The source could be a rupture of a blood vessel or broken stitch of the surgical wound. 
Then, the most likely cause for the sudden blood pressure drop in this patient would be massive bleeding.
