1) Always be able to explain anion gapped metabolic acidosis.
2) Remember K.I.L.R for causes of AG metabolic:
•GI & small pupils = cholinergic
•Old, Deaf, & acidosis = ASA
•Bradycardia, Hypotension, & Elevated BS = CCB
•Acute Hepatic Failure: APAP, Acute Hepatitis, Med list!!!
•Sepsis in pump pt = consider withdrawal
Don't forget the Tox triad for most exposures EKG, BMP, and APAP level
