Log in to Reply Mark Tan 22nd May 2023 at 10:25 am I think several errors on this paper: 1d: head up tilt **decreases** VAP risk, not increase it. 4d: Metoclopramide does prolong QT interval. Answer states false.

You are indeed correct regarding the correct answers for the questions – 1d should be false as it has not been shown to increase VAP. But head up semi-recumbent position also not shown to reduce VAP with good quality trial data. Moderate quality evidence suggests a benefit. But answer to this question in particular is false. https://www.cochrane.org/CD009946/ARI_head-bed-elevation-versus-flat-bed-preventing-ventilator-associated-pneumonia-vap-adults-requiring And yes metocloperamide does prolong QT. I have updated the answers. Thank you!

I thought metoclopramide did prolong qtc?
Yes Metoclopramide does prolong QTc
I think several errors on this paper:
1d: head up tilt **decreases** VAP risk, not increase it.
4d: Metoclopramide does prolong QT interval. Answer states false.
