60
My patient requires 2 pre-treatment drugs for PONV; I gave zofran and decadron before her surgery. How many risk factors do you think she has? What are her chances of developing PONV based on this info?
2 risk factors = 40% chance of developing PONV
61
My chance of PONV is 20%. How many risk factors do I have? What drug(s) will you give me?
