FA pg 217. Too much oxygenation can cause free radical damage leading to retinopathy of prematurity

mmm21  Okay i might be retarded, but why i can’t understand that they r asking about the thing that is damaged ? πŸ˜‚πŸ˜‚ +2  
sahusema  Seriously! The question says "the goal of treatment is the protection of which of the following structures?" If too much O2 damages the retina, how is this treatment supposed to be protective to the retina? +  
ratadecalle  I think too much oxygen would be with the ventilator having a high FiO2 setting, which they don't mention here but I'm guessing thats the thing they're controlling to avoid oxygen toxicity? +  
burak  they didn't give the patient fio2 100%, question asks the reason for it. but in a very stupid way +2  
naught  Supplemental O2 may also cause bronchopulmonary dysplasia or intraventricular hemorrhage (germinal matrix, located in subventricular zone NOT choroid plexus) +

This question was asking about the adverse effects of proton pump inhibitors especially given previous kidney issues. PPIs decrease serum Mg and serum Ca absorption and can increase the risk of fracture (especially in the elderly).

yotsubato  PPI therapy *begins* the day she presents. She has not taken PPI before +5  
notadoctor  You're right, I missed that! +  
naught  MEN 1 is pituitary (monitor cortisol), pancreas, parathyroid (monitor calcium) but is not the ask of this question. +
