---|---|
What is Diabetes? | Diabetes is a disorder of carbohydrate, protein, and fat metabolism resulting from an imbalance between insulin availability & insulin need. |
How does Normal Insulin Metabolism work? | Insulin unlocks the cell wall to get glucose in. Also helps produce stores of insulin (reason why many diabetics gain weight). Insulin is continually released. Counter regulatory hormones are produced (ex. Glucagons) that keep insulin within normal ran |
What two hormones produced in the pancreas maintain a constant blood-glucose level? | insulin and glucagon. |
Where is insulin made and secreted by? | the beta cells of the pancreatic islets, small islands of endocrine cells in the pancreas |
What does insulin do for the liver? | Stimulates it to store glucose in glycogen, make proteins from amino acids, |
What does insulin do for the muscle cells? | same as the liver it Stimulates it to store glucose in glycogen, make proteins from amino acids, |
What does insulin do for the fat cells? | to form fats from fatty acids and glycerol |
Where is the protein hormone Glucagon made and secreted from? | the alpha cells of the pancreatic islets |
What does glucagon do for the liver and muscles cells? | • Stimulates the liver and muscles to break down stored glycogen (glycogenolysis) and release the glucose |
What hormone • Stimulates gluconeogenesis in the liver and kidneys? | Glucagon |
What hormone inhibits the liver and kidney cells from making glucose from intermediate compounds of metabolic pathways (gluconeogenesis)? | Insulin |

What does glucose in urine indicate? | indicates that the glucose has exceeded the renal threshold |
What are the nursing interventions in performing urine glucose - ketones test? | Discard first morning urine. Use second specimen. Don’t drink between first & second specimen. (or else it will dilute glucose |
What is the purpose of ketone - glucose test? | used to be how they monitored control. Only tells 3-5 hrs previous, not big picture. |
· Ineffective management of therapeutic regimen r/t ? | lack of knowledge (diet, exercise, weight control, medications, glucose monitoring) AEB continued hyperglycemia, inaccurate statements regarding diabetes and its management, and self-professed confusion regarding the patho. of diabetes and its treatment |
Risk for infection r/t ? | depressed immune system, inadequate circulation, and environmental pathogens. |
