Ch.20 Endocrine and Hematologic Emergencies Flashcards
Insulin and Glucagon
Insulin: helps glucose enter cells
Glucagon: Hunger stimulates liver to release glycogen to convert to glucose for fuel
Diabetes mellitus
-Impaired ability to get glucose into cells
Impaired insulin production or not enough receptors for insulin to bind to
Glucose can’t enter cell, blood glucose remains high + rises
Hyperglycemia
Onset: gradual
SKin: warm and dry
Infection: common
GI:
Thirst: intense
Hunger: present and increasing
Vomiting/abdominal pain: common
Respiratory:
Breathing: DKA -kussmaul
Odor: sweet/fruity
Cardio:
BP: normal or low
Pulse: weak and thready
Nervous:
Consciousness: restlessness, coma, slurred speech, unsteady gait
Treatment:
response: gradual 6-12 hours
Hypoglycemia
Onset: rapid
Skin: pale, cool, moist
Infection: uncommon
GI:
Thirst: absent
Hunger: absent
Vomit/pain: uncommon
Respiratory:
Breathing: normal, shallow to ineffective
Odor: normal
Cardio:
BP: normal to low
Pulse: rapid, weak
NErvous:
Consciousness: irritability, confusion, seizure, coma, unsteady gait
Treatment response: immediate after glucose administration
Diabetes mellitus type 1
Antibodies against pancreatic beta cells= less insulin
Glucose can’t enter cells
Symptoms:
polyuria: frequent urination
polydipsia: increased thirst
polyphagia: severe hunger
Diabeticketoacidosis (DKA)
fat metabolism and ketone production
Abdominal pain, body aches, nausea, vomit, altered LOC
Diabetes mellitus type 2
Resistance to effects of insulin at cellular level
Fewer insulin receptors
Obesity
Body makes more insulin to make up for increased blood glucose. Becomes inefficient and blood glucose doesn’t respond to insulin =insulin resistance
Type 2 medications
Glipizide
Glyburide
Metformin
Pioglitazone
Exenatide
Sitagliptin
Hyperosmolar hyperglycemic nonketotic syndrome (HHNS)
Type 2
hyperglycemia leads to dehydration, fluids discharged out of body through kidneys, kidneys overwhelmed and blood becomes more concentrated
Signs/Symptoms: hyperglycemia, altered LOC, dehydration, visual/sensory deficits, partial paralysis, seizures
Long term hyperglycemia
Don’t heal
numbness in hands and feet
renal failure
gastric motility problems
hypersmolarity
concentrated blood due to dehydration
Hypoglycemia reasons
-Insulin w/o food
-more insulin than needed
-insulin and acute illness
-insulin and routine change-exercise more, late meal
AEIOU-TIPS
Altered mental status
Alcohol
Epilepsy, endocrine, electrolytes
Insulin
Opiates and drugs
Uremia (kidney failure)
Trauma, temperature
Infection
Poisoning, psychogenic
Shock, stroke, seizure
Sickle cell disease
Hemoglobin S disease
Affects red blood cells
Sharp and misshaped cells means oxygen binding and unintentional clot formation (vasoocclusive crisis)
Short life span of RBCs
Anemia, gallstones, jaundice, vascular occlusion with ischemia
Hemophilia
Males inherit from mother carrier
Females from mother carrier and dad has disease
Decreased ability to clot
