Glucose Monitoring Flashcards
What is the first step in performing glucose monitoring?
Assembles equipment and supplies
Why is calibrating glucose meters important?
It ‘codes’ the meter and ensures accurate results
How often should controls be performed on hospital glucose meters?
Every 12-24 hours
What should you do if a home glucose meter value seems incorrect?
Perform controls
What is the primary site used for obtaining blood specimens in glucose monitoring?
Pads of fingers
What are alternative ways to obtain a blood specimen besides using finger pads?
- Arterial lines
- Central Venous Lines
- PICC Lines
- During lab draws
- Alternative site testing
What is the average fasting glucose goal for adults?
80-130
What are critical values for glucose monitoring?
Less than 40 or higher than 400
What is the Rule of 15 in treating hypoglycemia?
If glucose less than 70, DRINK 15 grams of carbohydrate and wait 15 minutes
What is considered 15 grams of carbohydrate?
- 4 ounces of juice or soda
- 3-4 glucose tablets
- 1 tablespoon of honey or syrup
What can lower glucose levels about 15-20 mm/dL?
- A 16-ounce bottle of water
- A 20-minute walk
What should be done if glucose remains above 250?
Test for ketones
What is a common protocol regarding oral diabetes medications during hospitalization?
Most are held due to procedures
What is the typical timing for blood glucose testing in the hospital for patients not eating?
Every 6 hours
What should you NEVER do regarding insulin without an order?
DO NOT HOLD INSULIN
Name a few brands of Continuous Glucose Meters (CGM).
- Medtronic Guardian
- Freestyle Libre 1, 2, 3
- Dexcom G6, G7
What does a Continuous Glucose Meter (CGM) do?
Helps with hyperglycemia and hypoglycemia

What does a Continuous Glucose Meter (CGM) do?
Helps with hyperglycemia and hypoglycemia
glucose number–re-access-new number–treat
When do you call the doctor? After you re-access patient
cluster care as nurse, on sides of finger for glucose stick, watch out for edema
Why should you waste blood? prevent lot
Make sure assure strips are not expired.
GOAL- glucose w/o diabetes less than 100
pre- diabetic stick twice/ 100-125 glucose number fasting
Over 125 glucose number- type ii diabees
fasting is 6-8 h for testing
Before treatment, Redraw lab
critical valve
less than 40 or higher than 400 is critical
Rule of 15
exam
If glucose less than 70, DRINK 15 grams of carbohydrate and wait 15 minutes.
Recheck glucose. If remains less than 70, DRINK 15 grams of carbohydrate. If greater than 70, eat a protein and 15 gram carbohydrate snack.
Drink first, then food
what is 15 g of carbohydrate?
- 4 ounces of juice or soda
-3-4 glucose tabs
1 tablespoon of honey
Nurse can never HOLD insulin on a sliding scale.
Nurse can hold insulin with a set dose with food
If blood sugar is low too often, reduce amount of insulin
