Q

Oral Glucose Tolerance Test.
What is it.

what does it evaluate

A

A loading dose of carbohydrates are given and the blood glucose is measured at intervals afterwards.
DM is diagnosed when measurements are above 200 mg/dl after 2 hours of CHO intake
This test evaluates insulin response to glucose loading.
If diabetic, the patient will have greatly elevated glucose levels for 1-5 hrs after glucose load.

44

Patient considerations for fasting lab draws

A

For fasting glucose pt must fast from any caloric intake for at least 8 hours. (overnight), sips of water are allowed.

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

assists with weight loss
reduced incidence of complications
54
Q

Insulin can not be taken by mouth as it’s a ___ and would be digested.

A

protein

55
Q

define onset of action

A

once insulin is injected until it begins to lower the blood sugar.

56
Q

define peak action

A

occurs when the insulin is working its hardest and the blood glucose is at it’s lowest point.

57
Q

action of oral hypoglycemics

A

The action is to either increase the production of insulin, or decreases glucose production by the liver.

62
Q

if hypoglycemia, give ___ oz of CHO. what are some examples of CHO

63
Q

Diabetic ketoacidosis (DKA) is an acute complication of diabetes mellitus characterized by:

A 
Hyperglycemia 
Ketonuria
Acidosis
Dehydration
Hyperkalemia
64
Q

pathophysiology of diabetic ketoacidosis

A

Insulin deficiency prevents glucose from being used for energy, forcing the body to metabolize fat for fuel.
The fat breakdown releases an acid substance called ketones.
As ketones build up in the blood, ketoacidosis occurs.

65
Q

In DK The body attempts to compensate for ____ by deepening the respirations, thereby blowing off excess CO2. These respirations are called ___ respirations.

A

acidosis

Kussmaul’s

66
Q

interventions for DK

A
  • -IV Fluids will be the initial treatment, the patient will be dehydrated.
  • -Insulin will be initially be added to the IV fluids.
  • -when Blood sugars down to 180, glucose may be added, to prevent hypoglycemia!
  • -ABG’s will be monitored in order to observe the acidosis.
  • -Monitor glucose levels every hour until stable
  • -Monitor specific gravities until patient is more stable with the dehydration problem.
  • -I&O
67
Q

Summarize Hyperosmolar-Hyperlycemia Nonketotic syndrome (HHNK)

A

Complication of diabetes mellitus TYPE II
It also primarily occurs in the elderly.
Precipitating stressful events (cardiac failure, burn, or chronic illness)
As the blood glucose rises, polyuria causes dehydration producing the hyperosmolar (concentrated) state.
Blood glucose can get as high as 1500
There are little or no ketones.
patient will not feel as ill as the patient with DKA.
S/S: extreme thirst, lethargy and confusion.

68
Q

Nursing intervention for HHNK

A
  • -Restoring Fluid Balance
  • -Assess patient for increasing s/s of dehydration, hyperglycemia, electrolyte imbalance.
  • -Monitor those LAB VALUES
  • -Institute fluid replacement therapy as ordered
  • -Administer insulin as ordered
  • -Maintain patent IV line.
69
Q

macrovascular complications of diabetes

A 
Atherosclerosis
Arteriosclerosis
HTN
Increase of LDL
Increase chance of stroke and heart attacks
Poor circulation in feet and legs
Increase clotting
70
Q

what is retinopathy

A

involves damage to tiny blood vessels that supply the eye
