RDS (respiratory distress syndrome) and O2 therapy complications are described on p.647 in FA 2019!
This is due to free radicles, which is also briefly touched upon on p. 210 of FA 2019
also I saw on one of the other NBME's that retinopathy is more likely than the intraventricular hemorrhage. I did some reading and found that the eyes adapt to local changes faster. So when you give them 100%02 their eyes get used to the elevation in 02 so when you take them off of it they upregulate a ton of VEGF to try to normalize back to the level they were used to on the 100%
I know Insulin cause shift K+ into cells due to closing of ATP-sensitive K channels (blocking K from leaving)? Does it increase K in the cells by another mechanism?
@dentist - Insulin stimulates the Na+-K+-ATPase pump, this drives K+ into the cell (Source: Amboss)
Another mechansim = acidosis causes hyperkalemia due to H+/K+ antiporters. H+ is high in blood so shifts into cells via this antiporter, which shifts K+ out. --potassium section of acid/base chapter in Costanzo physiology
Not really. Diarrhoea and dehydration are A/Es of Laxative use (for Sketchy fans remeber the spoiling mud bath).
