Wk 3: Caring for a Diabetic Pt/ Nutrition Flashcards
Type 1 DM
autoimmune destruction of Beta cells in our pancreas
-S/sx more abrupt
-common in youth
-NO ENDOGENOUS insulin production
-MUST have insulin replacement
type 2 DM
Beta cells in pancreas wear out and body becomes immune or resistant to insulin/body cells do not respond to insulin
-common in adults
-can go undiagnosed for long time
-some need insulin with PO meds
what are the 3 P’s of type 1 DM?
polyphagia -> excessive hunger
polydipsia -> excessive thirst
polyuria -> frequent urination
Common Symptoms of Diabetes
three P’s
fatigue
recurrent infections
slow healing
Non-modifiable risk factors for type 2 DM
family Hx
over 45 y/o
race/ethnicity
history of gestational diabetes
Modifiable risk factors for type 2 DM
Physical inactivity
High body fat/overweight
HTN
HLD
What labs are involved in monitoring diabetes ?
-Fasting BG (no food/drink for 8 hours)
Nml <126
-Casual BG
What labs are involved in monitoring diabetes ?
-Fasting BG (no food/drink for 8 hours)
Nml <126
-Orala Glucose Tolerance Test (to Dx gestational diabetes)
-Glycosylated Hemoglobin (HbA1C)
-Casual BG
Nml <200
-urine ketones
-lipid profile
low HDL, high LDL, high triglycerides
HbA1C test
-Average BG over 3 months
-used to Dx and evaluate effectiveness of interventions
-nml is 4-6%
> 6.5% is considered diabetic
acceptable range for diabetics is 6-8%
How do you take an Oral Glucose Tolerance Test
-consume oral glucose
-glucose taken every 30 minutes until 2 hours have passed
-fasting should be <110
- at 1 hour should be <180
-at 2 hours should be <140
A1C levels for
-Diabetics
-Pre-diabetes
-Normal
-diabetic: 6.5 or above
-Pre-diabetes: 5.7 - 6.4
-Normal: ~5
Fasting Plasma Glucose levels for
-diabetes
-pre-diabetes
-normal
-diabetes: 126 or above
-pre-diabetes: 100-125
-normal: 99 or below
oral glucose tolerance test for
-diabetes
-pre-diabetes
-normal
-diabetes: 200 or above
-pre-diabetes: 140-199
-normal: 139 or below
What is the criteria for a DM diagnosis
at least one of the following:
-A1C of 6.5% or higher
-fasting BG >126
-OGTT 2Hr level of 200
-Sx of hyperglycemia, a random BG >200, or hyperglycemia treatment
*usually a repeat lab is done before official diagnosis
*for Type 1 DM would beed an islet cell autoantibody test
What can you do for a pre-diabetic pateint?
-teach
-lifestyle modifications
-encourage close monitoring of BG and A1C
-monitor for: fatigue, slow healing, frequently being sick
-diet modification
What are some pharmacological considerations for a diabetic patient (specifically type 2 DM) when they are sick or hospitalized
-oral meds may be stopped when in the hospital
-might be put on insulin when in hospital, even if they do not normally take it
-BG can rise when sick
-hold metformin prior to surgeries
-Pt may be more prone to DKA or HHNS
-PO intake may be less, may need to alter insulin dose
-steroids make BG rise
When a patient with DM is sick, when should (you or) they call their provider
-urine ketones
BG >250
Temp >101.5 w/o response from Tylenol
Confusion/Disoriented/ Rapid Breathing
N/V/D
Fluid intolerance
sick >2 days
Frequency of BG checks depends on what
glycemic goals
type of diabetes
medication regimen
access to supplies and equipment
patients willingness
When would rapid or short acting insulin be given?
before each meal
When would lantus or long acting insulin be given?
at bedtime
Since Insulin is a high alert drug, what should you be checking/ know prior to administering it?
-current BG level
-check current diet order
-onset/peak/duration of insulin
-S/Sx of hypoglycemia
What do you do if your diabetic patient is NPO?
may need medication dosage change
What should you always do with a patient with a new diagnosis of DM?
-Make sure to educate properly about side effects, when to time insulin doses, and S/sx for hypoglycemia
-always observe new patients self-administer insulin
Hypoglycemia criteria and treatment
BG <70
Trx:
-FSBG
-rule of 15
What is the rule of 15?
if Pt is hypoglycemic but still able to swallow give 15g of simple carbohydrates
-FSBG in 15 minutes then eat regular meal
-if still <70 then repeat steps
(15g CHO should increase BG by 50)
Simple CHO include: 4Oz juice, regular soda, 3 glucose tabs
What can you give a patient that is hypoglycemic if they are unable to swallow or are unconscious?
IM Glucagon
IV D50
What are some symptoms of hypoglycemia?
diaphoresis, blurred vision, dizziness, anxiety, hunger, irritability, shakiness, fast heart beat, headache, weakness, fatigue
What are some causes of hyperglycemia?
what are some manifestations of it?
causes: illness, infection, self-management issues, stress
manifestations: weakness, fatigue, blurry vision, headache, N/V/D
Insulin Pumps
-SQ continuous infusions of rapid acting insulin
-be aware of: infections at pump site and increased risk of DKA if pump malfunctions
Macrovascular Complications of DM
damage to large vessels like:
-coronary arteries
-peripheral vascular
-cerebral vascular
*much higher risk for CVD
Microvascular Complications for DM
damage to capillaries:
-retinopathies
-nephropathies
-neuropathies
Loss of Protective Sensation (LOPS)
prevents patients from being aware that injury has occurred
-related to neuropathy
Diabetic foot care steps
- wash feet daily
- pat dry
- inspect feet daily
- use lanolin to prevent dryness
- mild foot powder for sweat
6.no commercial remedies - clean cuts with mild soap (NOT iodine/alcohol/adhesives)
- report skin infections
- trim nails
- separate overlapping toes with cotton
- do not go barefoot
- clean/ absorbent socks
- no hot water bottles
Nutritional considerations for diabetics
high fiber
low fat
low cholesterol
carb counting (especially with T1)
whole grains
sugar free alternatives work well
limit alcohol intake
**NEVER tell a patient to not eat a certain food group
Integumentary Concerns d/t DM
- Diabetic Dermopathy: reddish-brown spots
- Acanthosis Nigricans: brown/black thickening of skin
- Necrobiosis lipoidica diabeticorum: red patches around blood vessels
*all can improve when DM is being treated/controlled properly
