Q

T2D Facts

A
  • More common in adults (w/ risk factors)
  • Can go undiagnosed for years
  • Drs just screen for risk factors, not s/s
  • Pts are INSULIN RESISTANT —> treat w/ oral/SQ meds, may need insulin replacement

Q

Patients are more prone to what when they are sick?
T1D?
T2D?

Study These Flashcards
A

T1D -> DKA - diabetic ketoacidosis

T2D -> HHNS - hyperosmolar hyperglycemic syndrome

21
Q

What happens when a pt w/ DM gets sick w/ a virus?

Study These Flashcards
A
  • May not be eating or drinking.
  • Must check blood sugar often and treat as necessary
  • Still need to take oral meds if sick, if possible
22
Q

What are some teaching points for pts when they are sick and have DM?

Study These Flashcards
A
  • Notify HCP
  • Monitor BS more frequently (q2-4h)
  • Cont. to take meds
  • Prevent dehydration
  • Meet carb needs -> either via food or liquid
  • Rest
23
Q

When should the pt call their HCP when they are sick and have DM?

Study These Flashcards
A
  • Ketones in urine
  • BS >250
  • Fever >101.5 & is not responding to Tylenol
  • Confused/disoriented/rapid breathing
  • Persistent N/V/D
  • Unable to tolerate liquids
  • Illness lasting longer than 2 days
24
Q

Basal insulin vs bolus

Study These Flashcards
A

Basal - Long-time insulin

Bolus - “Mealtime” insulin -> rapid and short acting

25
Why do we give basal-bolus combos for insulin?
To mimic the body’s normal insulin production
26
Rapid-Acting Insulin
Lispro (NovoLOG) Onset: 15 min Peak: 1 hour Duration: 2-4 hours
27
Regular/Short Acting Insulin
Human regular (Novalin R/Humalin R) Onset: 30-60 min Peak: 2-6 hours Duration: 3-8 hours
28
Intermediate Insulin
NPH (Humalin N) Onset: 2-4 hours Peak: 4-10 hours Duration: 10-20 hours
29
Long Acting Insulin
Glargine (Lantus) Onset: 70 min Peak: None Duration: 24 hours
30
Is Insulin a high alert medication?
Yes!
31
What do you do before giving insulin?
1st - Check current glucose levels 2nd - Check diet order & pts oral intake tolerance Know onset, peak, duration of insulin and the type you’re giving Monitor for hypoglycemia
32
What BG levels are for hypoglycemia?
<70 Can show symptoms if greater than 70 depending on if the diabetes is uncontrolled
33
How do you treat hypoglycemia?
1. Check FSBG levels 2. The rule of 15 (if conscious and able to swallow) 3. Recheck FSBG levels in 15 min, then eat regular meal w/ protein 4. If still >70, repeat. When glucose stable, give additional food.
34
What is the “Rule of 15”?
- 15 simple CHO (4 oz juice, regular soda, 3 glucose tabs, 1 tbsp honey, 5-8 lifesavers) - Avoid sugars w/ fat (candy bar) because it delays absorption *15g of CHO should raise BG levels by 50!!
35
What do you do if the pt is hypoglycemic and unconscious?
IM glucagon | IV D50
36
What are the levels for hyperglycemia?
>250 - 300
37
What causes Hyperglycemia?
Illness, infection, self-management issues, stress
38
What are s/s of Hyperglycemia?
Weakness, fatigue, blurry vision, headache, N/V/D
39
What is the treatment for hyperglycemia?
- Check for ketones in urine - Insulin - Drink fluids, prevent dehydration - Education on prevention
40
Insulin pumps
- T1D - Rapid acting insulin - Pts receive continuous basal infusion - Required to check BS 4TID - Deactivated in hospital and switched to sliding scale - Cost $$$$$$
41
Chronic complications of Diabetes: Macrovascular Microvascular
Macrovascular - Damage to lg vessels - coronary arteries - peripheral vascular - cerebral vascular Microvascular - Damage to capillaries - Retinopathies - Nephropathies - Neuropathies
42
Macrovascular disease facts
- Women w/ DM have 4-6x more risk of CVD - Men have 2-3x risk of CVD Educate! - PREVENTION - Stop smoking, control BP, modify high fat diet
43
Microvascular disease complications
Retinopathy - Damage to retina Nephropathy - Damage to small blood vessels in kidneys - Leading cause of end stage renal dz. Neuropathy - Nerve damage due to metabolic imbalances - 60-70% of patients have
44
What are the highest risks for neuropathy in DM pts?
- Lower extremities and feet | - Foot ulcers and lower amputations common
45
Diabetic foot care
- Wash feet daily - Pat feet dry, esp between toes - Inspect feet daily for cuts, swelling, blisters, red areas - Lanolin to prevent dry skin and cracking, but not between toes - Mild foot powder on sweaty feet - Do not use commercial remedies to remove calluses or corns - Clean cuts w/ mild soap - Report skin infections or no healing sores - Trim nails after shower or bath and round corners - Separate overlapping toes w/ cotton - Do not go barefoot, wear open-toes, or plastic shoes. Shake soles before wearing regular shoes. - Clean, absorbent socks - No hot water bottles
46
Nutritional Concerns for Diabetes
- Balanced, high fiber, low fat, low cholesterol diet - Encourage clients to consume grains/fruits/legumes/milk - Limit simple carbs -> pasta and bread - CHO: 45-65% of intake - Fats: low in sat fat and trans fat; polyunsaturated fats best (fish) - Fiber: Promote fiber intake (beans, veggies, oats, whole grains) - Protein: Promote intake from meats, eggs, fish, nuts, and beans; 15-20% intake - Alcohol: limit intake; 1 daily for women, 2 for men
47
Exercise for DM patients
- Exercise can LOWER blood sugar - Do not exercise if glucose is >250 OR <80 - Best to exercise after meals - If more than 1 hour has passed since eating, eat CHO snack prior - Wear a medical alert bracelet - Proper fitting footwear
48
Nursing considerations for the hospitalized diabetic patient
- Stress/surgery can increase blood glucose levels - Common to be controlled at home but uncontrolled at the hospital - Wound healing is impaired in pts w/ DM - High risk of infection
49
Integumentary Concerns r/t DM
Diabetic dermopathy: reddish brown spots, shins Acanthosis nigricans: brown/black thickening of skin, skin folds Necrobiosis lipoidica diabeticorum: Red patches around blood vessels
