Chapter 19 Flashcards
What are the islets of Langerhans.
A small portion of the pancreas is filled with the islets of Langerhans.
Within these islets are alpha and beta cells.
The alpha cells produce glucagon.
Beta cells produce insulin.
What does the endocrine system do when you skip a meal?
What are bands of glucose level?
What are differences between Hypo and hyper glycemia part 2?
What are differences between Hypo and hyper glycemia?
What are Kussmaul respiration?s
Deep, rapid breathing; usually the result of an accumulation of certain acids when insulin is not available in the body.
What are the symptoms of Diabetic ketoacidosis (DKA) ?
Abdominal pain
Body aches
Nausea
Vomiting
Altered mental status or unconsciousness (if severe)
Difference between type 1 and 2 diabetes
In diabetes mellitus type 1, no insulin is produced, so there are no keys.
In diabetes mellitus type 2, there are fewer insulin receptors.
Common medication for type 2 diabetes
What happens with hyperglycemia?
In type 1 diabetes, hyperglycemia leads to ketoacidosis with dehydration from excessive urination.
In type 2 diabetes, hyperglycemia leads to a nonketotic hyperosmolar state of dehydration due to the discharge of fluids from the body systems and eventually out through the kidneys.
What are the long term symptoms of hyperglycemia?
Wounds that do not heal
Numbness in the hands and feet
Blindness
Renal failure
Gastric motility problems
What are the sympotms of type 2, hyperosmolar hyperglycemic nonketotic syndrome (HHNS)
Hyperglycemia
Altered mental status, drowsiness, or lethargy
Severe dehydration, thirst, and dark urine
Visual or sensory deficits
Partial paralysis or muscle weakness
Seizures
common reasons for a low blood glucose level
Administration of a correct dose of insulin with a change in routine
Administration of more insulin than necessary
Administration of a correct dose of insulin without the patient eating a sufficient amount
Administration of a correct dose of insulin and the patient developed an acute illness
What causes seizures?
Seizures are caused by:
Infections
Poisoning
Hypoglycemia
Trauma
Decreased levels of oxygen
Unknown causes
What causes Altered Mental Statuts?
Alcohol
Epilepsy, endocrine, electrolytes
Insulin
Opiates and other drugs
Uremia (kidney failure)
Trauma, temperature
Infection
Poisoning, psychogenic causes
Shock, stroke, seizure, space-occupying lesion, subarachnoid hemorrhage
Most of these items can be associated with or can cause hypoglycemia.
