Morphine shite
How would you go about a question asking to change the type of analgeisa a pt is getting when they’re on both MR and PRN morphine
- Add up the total dose of MR they’re getting
- Add up how much PRN they take in a day
- Combine MR and PRN dosese
- Go to “palliative prescribing” on BNF
- Find the conversion table
- Bob’s your uncle
what do you do if ALT is only slightly raised when on statins
