Diabetic Meds Flashcards

1
Q

A complex disorder of carbohydrate, fat,and protein metabolism resulting from the lack of insulin secretion by the beta cells of the pancreas or from defects of the insulin receptors; it is commonly referred to simply as diabetes.

Q

Criteria for Diagnosis of Diabetes

Symptoms = classic symptoms of hyperglycemia such as polyuria, polydipsia, unexplained weight loss
Two-hour plasma glucose level of 200 mg/dL or higher during and oral glucose tolerance test (OGTT).
Any positive finding for the above assessments should be confirmed by repeat testing on a different day

Q

How do we diagnosis diabetes? Fasting plasma glucose level of 126 mg/dL or higher is considered diabetes (Fasting means no caloric intake for at least 8 hours)
OR: Symptoms of diabetes + casual plasma glucose 200 mg/dL or higher. Casual means it is measured at any time of day without regard to time since meal.
OR: Two-hour plasma glucose level of 200 mg/dL or higher during and oral glucose tolerance test (OGTT). The glucose load (also called a dose) should contain the equivalent of 75 gm of glucose dissolved in water. Patient drinks the glucose and their blood glucose level is measured. Note that the OGTT is not recommended for routine clinical use. Any positive finding for the above assessments should be confirmed by repeat testing on a different day.
A person isn’t diagnosed with diabetes based on one result.

Cautions:
Allergy to sulfonamide antibiotic- may have cross allergy

A

Contraindications of sulfonyureas

50
Q

Hypoglycemia-#1
Weight gain
Skin rash, nausea, epigastric fullness, heartburn
teach them to eat regular meals, if they skipmeals they could have chance for lowered blood sugar, can cause weight gain

GI and other stuff but not as bad as metformin

A

sulfonyureas adverse effects

51
Q

Increase insulin secretion from pancreas (similar to sulfonylureas)
Shorter duration than sulfonylureas- given at each meal
Type 2 diabetes
Can be used with metformin (but not sulfonyureas since they function the same way)

52
Q

Advanced diabetes dependent on insulin
NPO status (such as fasting), alcohol use, advanced age

A

glinides contraindications
Contraindications similar to sulfonylureas

53
Q

Hypoglycemia- #1
Eat with dose
Weight gain common report

A

glinides adverse effects

54
Q

Insulin sensitizing drugs
Decrease insulin resistance by enhancing the sensitivity of insulin receptors
Affect gene regulation= slow onset of action over several weeks- may take months for full effect
Type 2 diabetes
May combine with metformin or sulfonyurea
Can be used with insulin
takes a long time for it to work, will take several weeks for it to really take full affect

65
Q

What are the hyperglycemic agents?

A

your patient goes into a hypoglycemic state and is conscious and able to eat, what would you do?

recheck in 15 minutes

provide balanced meal

instruct patients to maintain access to a source of glucose or glucagon at all times

67
Q

If patient is unconscious or eating is a risk and your patient goes into a hypoglycemic state?

A

Administer Glucagon (IM, Subcutaneous, or IV) or 50% dextrose (D50) IV
Turn patient to left side
Recheck glucose level
“Fast 15” once patient is aware

68
Q

Action: Increases glucose levels
Indication: antidote for hypoglycemic crisis/emergency, decrease GI motility
Available subcut., IM, or IV
Hypoglycemia Crisis = less than 50
Still treat symptomatic “normal”low blood glucose levels
you still need to treat symptomatic hypoglycemia even if its like 80 if theyre showing symptoms

A

glucagon

69

Contraindication:
Hypoglycemia due to starvation
Use caution in client with cardiovascular disease
Adverse Effects:
GI (nausea, vomiting)
