46
The hormone insulin is produced by beta cells in ____ ___ ______ of the pancreas
islets of Langerhans
47
Some insulin is made by the pancreas, but not enough. Sometimes the pancreas makes enough insulin but the cells are resistant to it. Characterized by hyperglycemia on lab value (blood and urine)
Type 2 diabetes
48
Defined as carbohydrate intolerance occurring during pregnancy. It is due to extra metabolic demands that pregnancy triggers
Gestational Diabetes Mellitus (GDM)
49
______ refers to blood glucose levels that are above normal, but do not meet the criteria for diagnosing diabetes
Prediabetes
50
Develops due to another chronic illness that damages the islet cells such as pancreatitis and cystic fibrosis. May be the result of medication use (most commonly steroids)
Secondary diabetes
51
When a patient has 3 or more of the following metabolic abnormalities: HTN, increased cholesterol, low HDL (below 40), increased triglycerides, obesity, fasting glucose greater than 100
Metabolic Syndrome or Syndrome X
52
Classic signs and symptoms of Diabetes
Polyuria, polydipsia, polyphagia
53
Below 100 mg/dL for a nondiabetic, or for a diabetic with good glucose control
Normal fasting blood glucose
54
This is when the blood is checked with no regards to the last meal. It is done randomly. Diabetes is diagnosed if this level is 200 or above and have signs and symptoms of diabetes with it
Casual plasma glucose
55
A loading dose of carbohydrates are given and the blood glucose is measured at intervals afterwards. This test evaluates insulin response to glucose loading. If diabetic, the patient will have greatly elevated glucose levels for 1-5 hours after glucose load
OGTT - Oral glucose tolerance test
56
What are the patient considerations for fasting lab draws?
- For fasting glucose pt must fast from any caloric intake for at least 8 hours (overnight) sips of water are allowed
- Advise patient to refrain from smoking before the glucose sampling
- Hold insulin or oral anti-hyperglycemic medications
- For postprandial test, advise patient that no food should be eaten during the 2 hour interval
- Check lab results before administering medication or food
57
Normal HbA1C is _ to _ %
4 to 5
58
This better determines the average blood glucose, rather than one single fasting blood sugar would
Blood glucose attaches itself to hemoglobin and forms glycohemoglobin
AKA: Glycated hemoglobin, Glycohemoglobin, Glycosylated hemoglobin
**This test will be inaccurate with those patients that have anemia
HbA1C
59
Capillary blood glucose values obtained by ___ ___ samples tend to be higher than values in venous samples
finger stick
60

NO!
61
Injection sites are to be ____ in order to avoid injury to the tissues
rotated
62
This medication is used for type 2 diabetes
The action is to either increase the production of insulin, or decreases glucose production by the liver.
Also used in conjunction with insulin.
Most need to be administered before a meal
Oral hypoglycemics
63
Block enzymes that digest starches
Alpha-Glucose Inhibitors
64
Slow the rate at which the liver releases glucose
Biguanides

Diabetic ketoacidosis (DKA)
71
This is a complication of diabetes type 2
It also primarily occurs in the elderly
As the blood glucose rises, polyuria causes dehydration producing the hyperosmolar (concentrated) state

73
This type of hypoglycemia occurs in the patient that is not diabetic. It is believed to be caused by the overreaction of the pancreas to eating. The pancreas senses a rise in blood glucose and produces more insulin than is necessary
