Diabetes; Type 1/2, metabolic syndrome, Bariatric surgery Flashcards
Normal BMI
18-24.9
Overweight BMI
25-29.9
Obese BMI
30+
What is defined as morbidly obese
Being 80-100lbs over ideal body weight
Or BMI over 40
Candidates for bariatric surgery
BMI is over 40 (35-40 may be a candidate if there is other co-morbidities, such as cardiopulmonary, diabetes or other disorders)
-Requires an intensive screening process, and further screening may be deemed necessary by insurance
Not a candidate for bariatric surgery
-Obesity is caused by metabolic or endocrine disorders (cushiness/ thyroid issues)
-Ongoing substance abuse or major psych disorder
-High risk surgical candidates
-Active malignancy
Bariatric surgery
-Not the first line therapy, tries other forms of weight loss first, which fail
-Majority of weight loss occurs in the first year, and 10-35% of weight is loss within 2-3 years
-Super picky about candidacy, lengthy pre-op screening, workup and evaluation
Nursing post op bariatric surgery
-Vitals, and urine output
-Pain control and mgmt
-Liquid intake
-Diet progression
-Encourage ambulation day one
-See change in status
-Nausea mgmt with antiemetics
-SCD and lovenox
-Bladder mgmt, foley discontinuation (prevent UTI)
-Cardiac monitoring
-Incentive spiro
-CPAP
-Ambulation is very important
When should you have a pt ambulate after bariatric surgery and why
Up and movin day one, helps with O2 exchange and bowel movement
How Much liquids can someone have right after bariatric surgery
-They can only have extremely small amounts, like 30 ml to start
-They cant drink with meals, need to drink between meals
Complications of bariatric surgery
Wound infection
-Hernia
-Bowel obstruction
-Stricture
-Leak
-Dumping syndrome
-Nutritional deficiencies
Signs of infection bariatric surgery
-Fever, drainage, smell, warmth, infection, pain
How would you treat a bowel obstruction bariatric surgery
-Dont use a NG tube (usually we do this for other senarios)
-Bowel rest is first line treatment
Dumping syndrome
-food and liquids entering the small intestine too quickly,
-refined sugar and other simple carbs
-Ranges from 15 min to 2 hr after eating
Pancreas
Contains alpha and beta cells, glucagon and insulin respectively
Alpha cells
Glucagon
Beta cells
Insulin
What type of cells are destroyed in type 1 diabetes
Beta
Liver
Keeps blood sugar levels stable, and stores extra glucose
Insulin (hormone)
Lowers blood glucose levels, acts as the “key” to allow glucose into the cells, if insulin isnt present, glucose chills in the bloodstream
Glucagon
Works to take stored glucose in the liver and bring it in the blood stream
Type 1 Diabetes
Absence of beta cells in the pancreas, due to an auto immune response. These guys are insulin dependent for life
-Peak onset is 11-13 but can occur usually in people younger than 30( However if there is some trauma to the pancreas it can induce type 1)
- As a result of no insulin, glucose from meals stays in the blood stream
-Can be genetic or environmental (Viral) factors however it is NOT lifestyle
-Thin at diagnosis, and will have ketones in the urine at diagnosis from breakdown of fat
-Needs exogenous insulin to survive
-DKA is a concern
Why are pt with type 1 thin at diagnosis and have ketones in the urine
Body is unable to use the glucose in the blood stream, body breaks down fat for energy instead. This causes fat reduction and ketones in the urine
Type 2 diabetes
Body can make insulin, but the body is not receptive to it, its like the “keyhole” is blocked or no longer AS receptive to it
-Body produces enough insulin to prevent breakdown of fat and ketones
-But its not enough for the bodys purposes, beta cells have to make more insulin and they are not able to meet demands which leads to hyperglycemia
-Mainly caused by life style habits
-Pt are usually over 30 and obese (Seen more and more often in kids)
-Slow and progressive and may go unnoticed for years
-Major complication for type 2 is HHNA
-Treatment starts with lifestyle changes -> Oral meds -> Insulin
-No ketones in the urine
How might a wound on a foot lead to a diagnosis of diabetes
Type 2 diabetes is slow and progressive and a pt may not realize that they have diabetes until some sort of acute event such as a chronic wound that is not healing. They enter the hospital for their foot and find out its due to a complication of diabetes. This is stressful for the pt as they came to the hospital thinking they are fine and come out with all these lifestyle changes
Gestational diabetes
Usually 2nd-3rd trimester
-More similar to type 2
-goes away after pregnancy but much more likely to have type 2 after as a result
-Risk factors that can lead to this include, obesity, over 30, family history, personal history , big babies
-Can lead to complications such as LGA babies and preeclampsia
-Blood glucose measured fasting (95-) and 2 hrs after meal (120-)
-Treated with diet and insulin
-Screened with glucose tolerance test
Causes of Type 1 diabetes
-Autoimmune
-Genetic
-Virus (Coxsackie virsu, mumps, congenital rubella are all associated with type 1,
-pancreatic damage or disease
Causes of type 2 diabetes
-Genetics
-Mainly lifestyle
-Poor diet
-Sedentary lifestyle
-Obesity
-Metabolic syndrome
A nurse is providing discharge teaching to the parents of a child who has a new diagnosis of diabetes mellitus. Which of the following statements by the parents indicates an understanding of the teaching?
A. “As he has type 1 diabetes, he will only need insulin until he outgrows the condition.”
B. “As he has type 1 diabetes, we will start with oral medications and if his sugar is still uncontrolled we will switch to insulin.”
C. “His type 1 diabetes was caused by eating too much candy and soda.”
D. “His type 1 diabetes was caused by his body attacking his pancreas.”
D. “His type 1 diabetes was caused by his body attacking his pancreas.”
Type one is an auto immune mediated attack on the beta cells of the pancreas. A is incorrect as this disease is a lifelong condition. B is incorrect as this reflects type 2 diabetes, and oral medications are not effective for a pt with type 1. C is reflection lifestyle habits causing diabetes which is true for type 2 however for type one it is more autoimmune.
When providing education to the patient with Type 2 diabetes mellitus, the nurse correctly states which of the following clinical characteristics?
A. “The onset is due to pancreatic alpha cell destruction.”
B. “Patients notice severe weight loss and are devoid of body fat.”
C. “You can help control glucose with diet control and exercise.”
D. “The onset is autoimmune mediated.”
Answer:C. “You can help control glucose with diet control and exercise.”
A. “The onset is due to pancreatic alpha cell destruction.”
-The alpha cell produces glucagon, which is not affected by type 1 or 2
B. “Patients notice severe weight loss and are devoid of body fat.”
-This is reflective of type one, in which the body breaks down fat as they are not able to use the sugar in the blood stream
D. “The onset is autoimmune mediated.”
-This is reflective of type one which the body launches an autoimmune response on the beta cells of the pancreas
Diagnostic Criteria for Diabetes: Random glucose

Diagnostic Criteria for Diabetes: Fasting glucose
126, Not eating or drinking for 8 hours
Diagnostic Criteria for Diabetes: Oral glucose tolerance test

4 S’s of hyperglycemia
-Sepsis
-Stress
-Skipping insulin doses
-Steroids
-Also can be caused by hormone therapy or thiazide diuretics
- This can occur even in non diabetics, and may need insulin in their hospital stay
Number one cause of hyperglycemia in the hospital
Sepsis

-Alc
-Insulin peak times (Lack of coordination when theyre eating)
What meds block symptoms of hypoglycemia
Beta blockers
MAO inhibitors
Bactrim (Antibiotic)
A person comes into the ED with Diaphoresis, tachycardia, hunger, slurred speech, When their blood sugar is taken it reads 150. What may the nurse suspect is afflicting the patient in relation to their diabetes

Hypoglycemia treatment
-Sugar!
-If they can eat give them a simple sugar that can be digested fast
-Dont want any lipids with it as it slows digestion
-Give them

-Dont give them
Peanut butter or high fat milk
If unconscious give them IV dextrose
