Hope this helps:
I think the nurse who takes care of the patient is at fault because she is supposed to take care of her and not let her get worse.
I also choose the nurse because the patient says that she's experiencing pain at the surgical site and the nurse provided the patient with wound care on the day the patient was in the ER
But if this is a trick question I would say the sister because she is the only other character in this scenario that doesn't have a backstory like the patient and the nurse and then the information that is missing would be the sister's backstory.
To find where I got the characters I put them in bold.
A 48 year old female patient has recently undergone surgery for a knee replacement.
The past medical history of the patient includes Diabetes Type 2, a partial hysterectomy, asthmatic, and Irritable Bowel Syndrome.
Two weeks post-op the patient presents in the ER with an elevated temperature, swelling, and redness in the surgical incision site.
The patient also says that she's experiencing pain at the surgical site and chills.
Her sister accompanied her to the ER and said that the patient has started back smoking cigarettes and only cleans the surgical site every couple of days.
The nurse who took care of the patient in the recovery room the day of the surgery provided the patient with wound care instructions and used aseptic technique, proper PPE, and instructed the patient on wound care.
