The head of the pancreas is located adjacent to the duodenum, somewhat centrally behind the stomach and more to the ___ side of the body
A. Left
B. Right
B. Right
Glucagon _______ blood glucose levels
A. Increases
B. Decreases
A. Increases
Glucagon inhibits insulin
A. True
B. False
B. False
*Insulin inhibits glucagon
You can only have one type of diabetes, either type 1 or type 2
A. True
B. False
B. False
You can have a combo
The brain is dependent on insulin for a steady supply of glucose
A. True
B. False
B. False
*not directly insulin dependent - the brain has GLUT1 transporters
What are the 3 main roles of insulin?
- Help muscle, fat, and liver cells absorb glucose from the bloodstream
- Stimulate the liver and muscle tissue to store excess glucose in the form of glycogen
- Lower blood glucose levels by reducing glucose production in the liver
John is an insulin-dependent diabetic. He has not taken a shot this morning, but says that he “ate a little something” for breakfast. He starts exercising and soon is complaining of blurred vision and extreme fatigue. Why will he have a strong, fruity breath odor, and what is happening metabolically in his body?
- Diabetic ketoacidosis
2. When insulin isn’t available, fats are used for metabolism. The byproduct of ketone bodies causes decreased pH
What do you think his blood glucose would be, if tested?
Very high - over 250 most likely
Susie also shows up to exercise, but she has an insulin pump and has had a meal. She does a finger-stick test, and her blood sugar is 230 mg/dL. She says she feels fine. Is she safe to exercise? Why?
A. Yes
B. Over 250 or higher is a caution zone - blood sugar may be too high for a person to exercise safely. Before exercising, test your urine for ketones. The presence of ketones indicates that your body doesn’t have enough insulin to control your blood sugar
Fred is also part of the group, and his finger stick shows 80 mg/dL. Should he exercise? If not, what can he do?
A. Lower than 100 - should not exercise
B. He can eat a snack and see if it increases
Who is at the greatest risk for ketoacidosis?
A. Type 1 diabetic with HbA1c level of 8.5%
B. Type 2 diabetic with HbA1c level of 8.5%
C. Type 1 diabetic with HbA1c level of 6.5%
D. Type 2 diabetic with HbA1c level of 6.5%
A. Type 1 diabetic with HbA1c level of 8.5%
Ketoacidosis and type II diabetes
Rare
You place a hot pack on Mrs. Jones’ back as part of her tx for LBP. She has an insulin pump on her lower left abdomen. Will the hot pack interfere with insulin absorption? Why or why not?
- No
- They are on opposite sides so will have no play
- Heating modalities increase absorption speed of insulin from subcutaneous sites - would alter if it was right over the pump
When insulin levels in the blood rise, this means that glucose is getting into the cells
A. True
B. False
B. False
*may be insulin resistant
Some glucose in the urine is normal
A. True
B. False
B. False
