8
Q
Large anion gap (excess anions), no ketones, metabolic acidosis. What is the cause?
A
Methanol, ethanol, lactate. Metformin overdose?
9
Q
Definition of Type 2 diabetes?
A
- Fasting glucose > 7.0mM
- Glucose tolerance test (75 grams glucose at time 0)
- Plasma glucose > 11.1 mM at 2 hours
- (2h value 7.8 - 11.1 = impaired glucose tolerance)
