Endocrine/diabetes Flashcards
Insulin secretion is an example of
Negative feedback (like a thermostat)
Where is insulin secreted?
Pancreas
Positive feedback
Rising hormone levels cause another gland to release a hormone that then stimulates more releasing of the first hormone
Negative feedback
If something gets too high or too low it stimulates the release if a hormone to bring it back down or to make it rise
What inhibits insulin secretion
Low blood glucose levels
What is insulin responsible for after a meal?
The storage of nutrients
What cell produces insulin
Beta
An IGT diagnosis is made when what values have been measured
140-199 mg/dl
Someone with prediabetes will most likely not have any symptoms. What parts of their bodies will have long lasting affects though?
Heart and blood vessels
You are determined diabetic if your Hgb A1C is higher than
6.5%
You ate diagnosed with diabetes if your fasting glucose is higher than
126 mg/dl
100-125 is prediabetic
You have a patient with a very high blood glucose level and is unresponsive. What symptom would lead you to think it was DKA rather than HHNS
Rapid, deep breathings
Kussmaul
What should you always remember when treating HHNS
FLUIDS
Metformin (glucophage)
Glucose-lowering agent
Reduces glucose production by the liver
It is used as a first-therapy option for type 2 pts
Sulfonylureas
Increase insulin production from pancreas
2nd-line therapy option if metformin doesn’t work
