Differences between DKA & HHNS |
|
Definition
- glucose levels: DKA = >300 HHNS = > 600

- Ketone levels: DKA: Present HHNS: Absent
- Serum OmA: DKA: High HHNS: Very High
- Serum pH: DKA: Metabolic Acidosis HHNS:no acidosis
|
|
|
Term
What happens to electrolytes with DKA & HHNS |
|
Definition
- DKA:
- Na increases due to water loss
- K initially low due to diuresis
- K may increase due to acidosis
- HHNS
- Na increases due to water loss
- K low due to diuresis
|
|
|
Term
What happens with serum renal studies with DKA & HHNS |
|
Definition
- Both Increased secondary to dehydration
|

Term
What happens to potassium with insulin therapy? |
|
Definition
- Potassium will shift into the cells with insulin therapy.

- Make sure urinary output is adequate before administering potassium.
|
|
|
Term
What is treatment for severe acidosis (pH < 7.0) |
|
Definition
- Admisistration of sodium bicarbonate by slow IV infusion
- Need to monitor K levels because too quick of correction of acidosis can lead to hypokalemia.
