The first nursing diagnosis is more appropriate for conditions such as visual/ auditory distortions, hallucinations, bizarre thinking.
A more appropriate high-priority nursing diagnosis would be:
Acute Confusion r/t anesthesia/ surgery, and possible medication reaction secondary to IV meperidine AEB pt reportedly asks questions about things that have already been discussed and asked one question three times
Acute Pain is no longer an issue, since the patient has just received IV meperidine and is resting comfortably.
Think about risks associated with surgery, risks associated with anesthesia, risks associated with meperidine (Demerol) use. Then, remember your ABC's and Maslow's (Safety concerns top priority).
So, what about
Risk for Aspiration?
Risk for Falls?
Risk for Injury?
Can you think of any others?
Hope this helps
