infusion; insulin bolus and increase if sugar don't drop, drop by 100 no
more then 200 next 4hrs, drip till labs good, wean when 150-250, stop 2-
4hr after SC injections


sodium bicarbonate drip
- Correct Answer - only infused with ? in severe acidosis or
hemodynamically unstable; Correct severe acidosis (pH<7.1) until pH
reaches > 7.1


Electrolytes DKA and HHS correction:
- Correct Answer - will drop with insulin, urine > 50 before you give K+, if
>5.2 do not give check q2, if K+ is < 3.3 add 10-20 mEq to fluids until >
3.3 is for


HHS correction fluid
- Correct Answer - fluid is priority, 1-2-liters (0.9% NS) first 2 hours, if NA
low use NS, normal give 0.45% at 250-500hr. BS 250 D51/2, fluid loss 6-
12L, 50% deficit give first 8-12hr, rest next 24-36hr for what condition
