Flashcards 1(16)
DKA stands for?
Diabetic Ketoacidosis.
HHS stands for?
Hyperglycemic Hyperosmolar State.
Key difference in blood glucose levels?
DKA: >250 mg/dL, HHS: >600 mg/dL.
True or False: DKA is more common in Type 1 diabetes.
True. DKA primarily occurs in Type 1 diabetes.
Common symptoms of DKA?
- Kussmaul respirations - Abdominal pain - Fruity breath odor
Common symptoms of HHS?
- Severe dehydration - Altered mental status - High blood osmolarity
What causes metabolic acidosis in DKA?
Accumulation of ketones lowers blood pH.
Primary nursing action for DKA?
Administer IV fluids and insulin.
Fluid replacement for HHS should prioritize?
Restoring intravascular volume gradually.
What lab value indicates acidosis in DKA?
Arterial blood pH < 7.3.
Electrolyte imbalance to monitor in DKA?
Potassium levels; risk of hyperkalemia.
Causes of HHS include?
- Infection - Dehydration - Stress
Fill in the blank: DKA leads to ________ due to ketone bodies.
Metabolic acidosis.
Why is HHS more dangerous than DKA?
Higher blood glucose and osmolarity lead to severe dehydration.
What is the initial treatment for both DKA and HHS?
IV fluids to rehydrate.
Nursing priority during DKA management?
Monitor vital signs and blood glucose levels.
Flashcards 2(16)
What is the primary cause of DKA?
Insulin deficiency leading to hyperglycemia.
What are common symptoms of HHS?
Severe dehydration, altered mental status, hyperglycemia.
True or False: DKA occurs primarily in Type 1 diabetes.
True. DKA is more common in Type 1 diabetes due to lack of insulin.
Fill in the blank: The primary electrolyte imbalance in DKA is ______.
hyperkalemia.
What is the typical blood glucose level for HHS?
Usually exceeds 600 mg/dL.
Compare DKA and HHS onset speed.
DKA: Rapid onset (hours to days). HHS: Slow onset (days to weeks).
What should you monitor in DKA patients?
Blood glucose, electrolytes, ketones, vital signs.
Cause → Effect: Lack of insulin → ______.
Increased ketone production leading to acidosis.
What is the treatment for HHS?
Fluid replacement, insulin therapy, electrolyte management.
True or False: DKA requires immediate intensive care.
True. DKA is a life-threatening condition needing urgent management.
What is a common lab finding in DKA?
Metabolic acidosis with an increased anion gap.
What are early signs of HHS?
Polydipsia, polyuria, weight loss.
Fill in the blank: Serum bicarbonate levels in DKA are typically ______.
<15 mEq/L.
What is the primary goal in treating DKA?
Restore normal metabolic state, correct acidosis.
What is the recommended IV fluid for initial DKA treatment?
Normal saline (0.9% NaCl) is preferred.
Compare the osmolarity in DKA vs HHS.
DKA: Normal osmolarity. HHS: Elevated osmolarity (often >320 mOsm/L).
