Short Acting Insulin Nursing implications

-only insulin that can be given via IV - give 20 -30 mins prior to meal **** can be use for sliding scale insulin*** - HIGH ALERT MED!!!! = 2 licensed RN to verify dosing prior to administrating

Rapid Acting insulin also called what? to provide what ?

....bolus insulin, ....coverage for meals

Insulin secretion: 1) insulin mRNA is transcribed & protein is synthesized where? 2) proteolytic processing occurs where?

1) Beta-cells of the pancreas 2) in the ER of beta-cells

What are the metabolic changes in Type 1 Diabetes?

1) Body interprets a fasting state: triggers gluconeogenesis. 2) Ketosis results from the massive mobilization of fatty acids from the adipose following hepatic ketogenesis. 3) Hypertriacylglycerolemia: excess FAs converted to TAGs & packaged into VLDLs, elevated chylomicrons & VLDL due to increase in lipoprotein lipase activity.

What are the metabolic changes in Type 2 Diabetes?

1) Gluconeogenesis to produce more glucose. 2) There is a diminished effect of insulin on target tissues as a result of insulin resistance. 3) Hypertriacylglycerolemia: elevated chylomicron & VLDL due to decrease in lipoprotein lipase activity.

Long acting insulin side effects

1) major side effect is hypoglycemia 2) sign and symptoms of hypoglycemia happen SLOWLY!!!!!

Long acting insulin nursing implications

What is Type 1 Diabetes?

Aka. juvenile or insulin-dependent diabetes (IDDM). 10% of diagnosed cases. Onset sudden during childhood or puberty. No insulin production due to loss of pancreatic beta-cells (auto-immune destruction). Treated by insulin replacement therapy. Patients are normally thin.

What is Type 2 Diabetes?

Aka. non-insulin dependent diabetes (NIDDM). 90-95% of diagnosed diabetes cases. Progressive disease w gradual development. Insulin resistance combined w inadequate insulin secretion. Risk factors include age, physical activity, obesity, genetics. Treatment: physical activity, weight loss, diet control (limited carbs), oral medications to control BGL.

Intermediate insulins may also be used as what, to control what?

Basal insulin, to control fasting blood sugar

DM is widespread, and is the sixth-leading cause of death in the United States. Ninety percent of patients with diabetes have type 2 DM. 10% have type 1 DM.

Epinephrine mobilizes fat & glycogen stores. When is it released?

During physical exertion, stress, cold exposure & hypoglycemia.

In the fasting or starvation state, low blood glucose levels in circulation triggers the release of ___?

Glucagon.

In the fed state, what signal triggers insulin production?

High glucose levels in circulation.

if pt is unconscious, give glucagon what route?

IM

What is prediabetes?

Individuals at high risk of developing type 2 diabetes have impaired fasting glucose (IGF) and / or impaired glucose tolerance (IGT). Development of disease can be prevented by lifestyle changes (weight-loss, exercise, appropriate nutrition, control of hypertension and dyslipidemia).

What are the inhibitory effects of insulin?

Insulin inhibits: - Gluconeogenesis - degradation of stores: glycogenolysis, lipolysis

What are the promoting metabolic effects of insulin?

Insulin promotes: - glucose uptake - biosynthesis --> proteins - storage: glycogen (glycogenesis), fat / TAGs (lipgenesis) - fatty acid synthesis

before meals

WHERE? is it insulin

beta cells of pancreas

MOA: insulin

binds to receptor site allowing glucose to enter cell, aid in metabolism of carbohydrates, fats, and proteins; stores glucose in liver and convert glycogen to fat

WHEN? is it given glucagon

blood sugar low

glycogenolysis

breakdown of liver glycogen

what is glycogenolysis?

breakdown stored glucose = increase blood sugar

term: blood glucose level high and low, vary within minutes

polydipsia, polyuria, polyphagia, HOT & DRY, coma

term: increase hungry

polyphagia

term: increase frequency urination

polyuria

Rapid Acting insulin nursing implication

pt. should eat within 15mins of administration - these insulins are used to prevent elevated BS following meals - ****used for sliding scale insulin coverage - HIGH ALERT MED!!!! = 2 licensed RN to verify dosing prior to administrating

hot & dry =

sugar high

Insulin causes glucose

to move out of the cells

There has been a sharp increase in type 2 diabetes related

to rates of obesity in the United States.

type I or type II: related to obesity

type II

Nursing Care for Diabetes Mellitus

Clients face lifelong changes in lifestyle and health status Major role of the nurse is that of educator in both hospital and community settings Plan of care and content differ according to the type of diabetes Nursing care focuses on teaching to manage the illness

need some candy
