Antepartum: Pathophysiology Diabetes Mellitus Flashcards
In DM the pancreas fails to produce____or doesn’t make enough_____
Insulin
The function of insulin (1)
Assist carbohydrates into cells
Without insulin what happens? (4)
1) Cells become energy depleted2) Serum glucose levels increase…which increase osmolarity in serum and this increase in osmolarity damages vessels3) Hyperglycemia occurs4) Cells break down their stores of fat and protein for energy5) Fat breakdown results in ketosis (acidic)6) Protein breakdown results in negative nitrogen balance
Fat breakdown results in? (1)
Ketones possible leading to ketone acidosis
Protein breakdown results in (1)
Negative nitrogen balance
4 Cardinal Signs of Diabetes Mellitus
1) Polyuria2) Polydipsia3) Polyphagia excessive hunger4) Weight loss
4 Primary classifications of diabetes is based on____?
CAUSE of diabetes
Type 1 Diabetes: 1 cause
Develops due to destruction of beta cells in pancreas and no/reduced insulin production
Type 2 Diabetes: 2 causes
Most common type of diabetes1) Insulin secretory defect2) Insulin resistance of cells
Other specific types of diabetes: ( 3 examples)
8 sub categories: examplesGenetic defectDrug-inducedEndocrine disorder
Gestational Diabetes Mellitius
Any degree of glucose intolerance that first is first dx during pregnancy
Adult: Acceptable Glucose Serum Range
65-99 mg/dl
Child: Acceptable Glucose Serum Range
60-100 mg/dl
1 day old: Acceptable Glucose Serum Range
40-60 mg/dl
2 days old to 2 years old: Acceptable Glucose Serum Range
50-80 mg/dl
Danger Range for Serum Glucose Levels
< 40 ; >400 mg/dl
1) A1C result indicates?2) AIC acceptable result for previously dx diabetic3) AIC pre diabetic range (pt in this range are high risk for developing diabetes)4) AIC diabetes dx5) AIC range for normal non diabetic
1) How well diabetes is being managed over a 2-3 month period2) AIC acceptable result for previously dx diabetic 73) AIC pre diabetic range 5.7-6.44) AIC > 6.5 on two separate tests 5) AIC range for normal non diabetic 4.5-6
Factors that can effect accuracy of AIC test (4)
1) Excessive bleeding2) Recent blood transfusion3) AIC is based on HbA if pt has Hb variant results may come in low and another test is used4) Iron deficiency /false high
