Carbon Monoxide (neuro sxs) -->100% O2 via non-rebreather
Pt with depression, comes in with anticholinergic effects (dilated pupils, intestinal ileus, tachycardia, dry mouth, urinary retenion), respiratory redepression, arrythmia/cardiotoxicity
TCA OD…antiCholinergic, Cardiotoxicity, Coma, Confusion
–>Tx: NaHCO3
Benzo toxicity/OD
CNS depression without much else. Less risk of resp depression/coma than barbiturates. Pupil size normal, respiratory rate may be normal.
–>phenytoin and alcohol OD look similar but will have +Nystagmus

how do you work up abnormal nipple discharge?
Bloody or serous: MRI or US
Milky/nonbloody: blood tests
–>BUT…if there are skin changes/lumps, do MRI/US first
Endometriosis is discovered during an operative procedure. How is this treated?
Asx endometriosis = no treatment…OBSERVE
if sx, could do nsaids, OCPs, progesterone IUD
