NURS205 Diabetes Exam Questions And Accurate AnswersWhat are the two types of functions of the pancreas Answer exocrine: to release enzyme
to aid digestion upon stimulation
endocrine: to produce insulin
What is the endocrine function of the pancreas? Answer Alpha cells of the pancreas
produce: glucagon= raises blood sugar levels
Beta cells of the pancreas produce: insulin= lowers blood sugar levels by facilitating the
uptake of glucose by cells, and stimulating the liver and muscles to store excess
glucose as glycogen
What happens to our levels of blood glucose - what is ingested we eat -> broken down by
digestive system, carbohydrates of food into glucose -> glucose enters the blood
the rise in blood glucose after consuming a meal-> induces the secretion of insulin
insulin released-> blood glucose levels-> normal range
compare normal blood glucose levels vs "normal" blood glucose levels in a hospital
setting - Answer 1. 4.0-6.0
2. hospital can be 4-8/10 because of abnormal diet or stress hormones that affect
glucose
what is the role of insulin - Answer It allows glucose to be taken into the cells of the
body.
what are the counter-regulatory hormones - Answer glucagon, epinephrine, growth
hormone, cortisol
- oppose the effect of insulin
- stimulate glucose production and output by liver
, - decrease movement of glucose into the cells
social determinants of health- lower socioeconomic status
Aboriginals

6.1-6.9 mmol/L -2hr plasma glucose levels between 7.1 - 11 mmol/L What are the ways to
diagnose diabetes, and the ranges? Answer: Diagnosis of diabetes Fasting glucose test
produces result of >7mmol/L Oral glucose tolerance test- 2h plasma glucose in a 75g
oral glucose tolerance test >11.1mmol/L Hemoglobin A1C test- A1C > 6.5% Random PG
>11.1 mmol/L + symptoms
what is diabetes mellitus - Answer a multisystem disease related to abnormal insulin
production, impaired insulin utilization
- largest financial burden on the Canadian Health Care system
what are the statistics of diabetes - Answer - Canadian adults with diabetes are twice as
likely as people without diabetes to die prematurely
- diabetes is a contributing factors in the deaths of approx 41500 Canadians each year
what are the factors that, singly or in combination, cause diabetes - Response genetic
(greater percentage of body fat)
- autoimmune (diseases that destroy pancreas cells)
- viral
- environmental (lifestyle)
