12

what are kassmaul respirations?

when the respiratory center increases the rate and depth of breathing to compensate for the acidic state produced by DKA

13

what is ketonuria?

ketones in the urine

14

DKA is treated with

  • fluids for dehydration
  • insulin to reduce hyperglycemia and acidosis
  • correction of electrolytes
15

what IV fluid is administered first?

0.9% NS to replace the sodium losses

16

after 2 to 3 hours, the IV solution is changed to

0.45% normal saline to prevent hypernatremia
