- Mild
Presentation
- Lifestyle modifications
- Diet
- Carbohydrates (Less than
10% of calorie intake)
- Fats (Less than 7%
of calorie intake)
- Proteins (Limited to
15% of calorie intake)
- Exercise
- 30 minutes a day, 5
days a week
- Increases insulin receptor
sites, lowers blood sugar
- Moderate to Severe
Presentation
- Medication in conjunction with
lifestyle modifications
- Drugs
- First-line
Medication
- Biguanides
- Increases insulin sensitivity, therefore increasing
glucose transport into tissues
- Decreases glucagon, therefore
reducing glucose production
- Can decrease A1C levels by
1%
- If blood glucose hasn't improved, add another
medication
- Thiazolidinediones
- Increases insulin transport and sensitivity
on cell receptors
- Improves insulin use at tissues
- Sulfonylureas
- Inhibits potassium channels on beta cells
- Influx of calcium in beta
cells
- Releases
insulin
- If blood glucose still hasn't improved, add insulin to treatment
- Insulin
- Issues with insulin therapy
- Hypoglycemia
- Could be caused
by overdose of
insulin
- Allergic Reaction
- Lipodystrophy
- Can result in areas of insulin if injection
site is unchanged
- Somogyi Effect
- Rebound effect from too
much insulin causing
hypohlycemia
- Dawn Phenomenon
- Hyperglycemia when waking in the morning due to
hormones that counter insulin during this time
- Meglitinides
- Increases insulin production
from beta cells in pancreas
- Alpha-Glucosidase
Inhibitors
- Slows carbohydrate
absorption
- Nursing Care
- Assessment
- Patient's ability to perform ADL/iADL
- Community Dwelling
Patients
- Assisted Living
Facilities
- Hospitalized Inpatients
- Nursing Facility
(Long-term)
- Mentally incompetent patients
- Confused, cognitively dysfunctional, or delirious
- Depression
- Past health history
- Viral infections
- Respiratory Syncytial Virus (RSV)
causes a change in the pathways that
regulate insulin levels
- Hypertension in diabetic patients
- Beta-blockers are not ideal
medications for diabetic
patients with HTN
- Beta-blockers not ideal because they have
been shown to ↑ TG, ↓ HDL cholesterol,
heighten insulin resistance, induce
systemic weight gain, and mask
hypoglycemia.
- Recent surgery
- eg. CABG surgery alters body glucose
homeostasis and increases stress
causing HHS
- Identify daily
basal rate and
bolus doses
- Obese individuals are more likely
to develop T2D than overweight or
normal BMI individuals
- Check for family history of diabetes
- Planning
- Actively engage patient to participate in
lowering blood glucose levels
- Prevent or delay T2D complications
- Prevent or eliminate acute hyperglycemic
emergencies or hypoglycemia
- Maintain appropriate blood glucose
levels according to patient profile
- Adjust lifestyle management with minimal stress
- Implementation
- Patient
Education
- Travelling with
diabetes
- Must continue medications as regular
- Self-Management
- Consider mentally incompetent
individuals. May require self-management
assistance
- Offer regular diet and preferred food items
- Offer food substitutions if meal intake is
<75%
- Increase blood glucose monitoring during
acute mental status or behaviour changes
- Depression
- Assess and treat depression
- Encourage physical
activity as possible
- Encourage socialization, especially during meals
- Consider physically incompetent individuals
ranging from the ability to perform ADLs
independently to ADL-dependent
individuals, to successfully apply
self-management skills
- For hospitalized patients who require
temporary self-management assistance
- Monitor BG levels as required based on patient
complexity and avoid relying on A1C levels due to
recent acute illness
- For rehab patients who require
partial self-management assistance
- Nursing staff monitor BG levels based on the
patient complexity of T2D and risks of
hypoglycemia. Use caution when
interpreting A1C levels as many conditions
interfere with A1C levels.
- After discharge, patients need to be able to perform
self-care skills and informed about
self-adminstration skills for home management
- For chronically ill patients who require full
or partial self-management assistance
- Continuous nursing staff education
to provide T2D management
- For community-dwelling patients who require no
self-management assistance (are fully independent)
- Educate the patient in preventing Type 2 diabetes
complications and maintaining BG levels within
normal ranges
- Plate Method
- Prevent or delay T2D and its
complications
- Encourage physical activity to
minimize the T2D effects of
overweight and obese individuals
- For overweight adults 45 YO and up, provide
routine screening to monitor prognosis
- For a Diagnosed T2 Diabetic
- Inform patients of the risks of
poor blood glucose control
- Advise healthy eating habits and nutrition levels and
help develop appropriate plate portions and meal
plans following Canada's Food Guide
- Continue oral agents and
insulin therapy as prescribed
- Track daily basal rates and
bolus doses to review
progression
- Monitor BG levels according
to patient complexity of
regimen
- Emotional Care
- Evaluation
- Review diet progression and connect
with overall health benefits
- Follow-up with patient after
discharge and evaluate outcomes
of patient goals and treatments
- A study showed that when nursing staff are actively involved in
patient therapy after discharge, including initial individual
meeting with an RN, attending a group class meeting for 1 to 2 h
(with 4-10 participants) once per week for 4 weeks, and
telephone follow-up calls for 1 year, resulted in greater mean
change in A1C and total cholesterol and LDL cholesterol
- If diet has improved or if physical
activity has improved, the risks of
CVD would normally decrease
- Check if there are any issues with blood
glucose control. If it is poorly controlled, then...
- Check for the absence of
injuries
- Collaborative Care
- Dietitian
- Works with the patient, RN and the
patient's health care team to develop a
meal plan, appropriate plating portion,
and guidelines to healthy eating habits -
get ready for the yummy fruits and
veggies!

foot - I promise he
won't bite!

- Pathophysiology
- Who could this affect?
- Over 35 years of age
- Risk increases with age
- Family history
- 80%-90% of patients
are overweight
- Due to increase intake of food, insulin is
constantly being produced
- Insulin receptors on cells become desensitized to
insulin
- Aboriginal
Hispanic
South Asian
Asian
African
- Has higher risk
- What is Diabetes Mellitus Type 2?
- The body normally goes through the following
cycle to maintain 4 to 6 mmol/L of glucose
- When you eat food, glucose begins building up in the blood
- Beta cells on Islets of Langerhans on
the pancreas secrete insulin
- Insulin "unlocks" receptors on cells
- This step in the cycle is the main
problem for patients with type 2
diabetes
- Insulin Resistance
- Insulin receptors on cells do not get
"unlocked" by insulin due to receptors
being unresponsive or loss of receptors
entirely
- Glucose begins to build up in the
bloodstream
- Results in hyperglycemia
and Type 2 Diabetes
- Analogy: When you put on glasses for the first time, you become very aware that they're on your nose and ears. But over
time, those sensations begin to dim until you forget that the glasses are even on your nose!
- Cells receive glucose to use for
energy
- Lowers blood glucose levels
as the glucose passes out of
the bloodstream
- Alpha cells on liver secrete
glucagon
- Abnormal glucose production
from liver could aid in
development of type 2
diabetes
- Promotes conversion of glycogen to
glucose
- Pancreas still makes insulin, but could
produce less because of fatigue
- Beta-cell mass loss
- Analogy: This is just one of the components of the homeostatic elements that our body goes through. It
very much works like a thermometer. It detects levels of glucose in the environment, and releases
elements to counteract them if they become to rampant.
- Complications
- Hyperosmolar Hyperglycemic
Syndrome
- BG levels rise immensely and
leads to severe dehydration
and very dark urine
- Hypoglycemia
- Happens when there's too much
glucose compared to insulin
- Tremors
Hunger
Excessive
Sweating
- Macrovascular
Angiopathy
- increased risk of heart diseases such as CAD and ACS
which can lead to increased risk of mortality
- Microvascular
Angiopathy
- Diabetic Retinopathy
- Retinal blood vessels are damaged and can cause
impaired vision and/or blindness
- Diabetic Nephropathy
- Glomerular arterioles
damaged and increases
the risk of kidney disease
and excretion of proteins
in urine
- Diabetic Neuropathy
- Peripheral nerves damaged and
increases susceptibility to injuries
without being aware of it
- Foot and lower extremity
- Gangrene
- Skin complications
- Decreased blood circulation lead to
changes in collagen, changing
appearance
- Infection
