Hypoglycemia Flashcards
Hypoglycemia definition
BG level less than 4mmol
When does hypoglycemia occur?
when your pt has too much insulin in proportion to glucose in the blood
Hypoglycemia may occur relative to a:
Example:
sudden metabolic shift – such as vigorous or rapid administration of insulin
4 common causes of hypoglycemia
Relative to mismatch in timing
- Food intake and peak action of insulin or oral hypoglycemic agents
- Too much insulin/OHA
- Too much exercise
- Pt fasting
7 Common Manifestations of Hypoglycemia
- Confusion
- Irritability
- Diaphoresis
- Tremors
- Hunger
- Weakness
- Visual disturbances
Untreated hypoglycemia can progress to:
- loss of consciousness,
- seizures,
- coma,
- and death (neuroglycopenic)
What is hypoglycemia unawareness?
- Person does not experience warning signs/symptoms
- Increasing risk for decreased blood glucose levels
What can cause hypoglycemic unawareness
Autonomic Neuropathy
How does autonomic neuropathy cause hypoglycemic unawareness
Lack of production of hormones that produce symptoms of hypoglycemia; don’t feel symptoms associated with hypoglycemia
What is autonomic neuropathy
damage to the nerves that control autonomic function
Who is most at risk for hypoglycemic unawareness and why?
Patients with prolonged diabetes diagnosis due to damage to vasculature
How does hypoglycemia unawareness alter BG control and management
- increases risk for decreasing BG levels
- therefore, loosened control of diabetes management. Patients allowed to go slightly high because they don’t recognize when they are going low
Brief overview of nursing management of hypoglycemia at first sign or symptom
- Check BG
- if < 4 begin treatment
- if > 4, investigate cause of symptom
- if equipment unavailable, initiate treatment and obtain BG when available
Adult hypoglycemia protocol for conscious/able to swallow/tube feed patient
15 grams of fast acting carbs
- 4 glucose 4 gram chewable tab
- 3 teaspoons of sugar in water
Evaluation for oral adult hypoglycemia protocol
Observe patient consuming treatment
Repeat BGM & treatment
q15min until BGM is >4 mmol/L
Do oral twice through than move to NPO algorithm
Alert MD after 2x
