Functions of Insulin

A

Transports and metabolizes glucose for energy

Signals the liver to stop the rel of glucose

Enhances storage of dietary fat in adipose tiss

Accelerates transport of amino acids (derived from dietary protein) into cells

Inhibits the breakdown of stored glucose, protein, and fat

132
Q

A

Changing time of injection of evening intermediate-acting insulin from dinnertime to bedtime

133
Q

Somogyi Effect

134
Q

Somogyi Effect Treatment

Treated by decreasing evening (predinner or bedtime) dose of intermediate-acting insulin, or increasing bedtime snack

135
Q

Hypoglycemia

A

Abnormal decrease of sugar in the blood (<70 mg/dL)

136
Q

Severe Hypoglycemia

A

BG <40 mg/dL

137
Q

Gerontological Considerations for Hypoglycemia

A

Older adults frequently live alone & may not recognize the sympt of hypoglycemia

W/ decreasing kidney function, it takes longer for oral hypoglycemic agents to be excreted by the kidneys

Skipping meals may occur due to decreased appetite/ financial limitations

Decreased visual acuity may lead to errors in insulin administration

138
Q

Mild Hypoglycemia Signs & Symptoms (SNS Stim)

A

Sweating

Tremor

Tachycardia

Palpitation

Nervousness

Hunger

139
Q

Mild Hypoglycemia Blood Glucose

A

54-70 mg/dL

140
Q

Moderate Hypoglycemia Signs & Symptoms

A

Glucose drop deprive brain cells of O2 (CNS)

Inability to concentrate

Headache

Lightheadedness

Confusion

Memory lapses

Numbness of the lips & tongue

Slurred speech

Impaired coordination

Emotional changes

Irrational/combative behavior

Double vision

Drowsiness

141
Q

Moderate Hypoglycemia BG Range

A

41-53 mg/dL

142
Q

Severe Hypoglycemia Signs & Symptoms

A

CNS is so impaired that the pt needs assistance of another person for treatment

Disoriented behavior

Seizures

Difficulty arousing from sleep

Loss of consciousness

143
Q

General Considerations for Hypoglycemia

A

Check the pt’s BG and correlate it w/ the signs and symptoms

144
Q

Treating ALERT Hypoglycemic Patients

A

Supply carbs
- 15-20 g of fast acting concentrated carbs
-> 2-3 glucose tabs
->4 oz of juice/soda
->1 Tb sugar, honey, or corn syrup
->8 oz of nonfat or 1% milk
->3 graham crackers

Then follow with snack: starch and protein
-Recheck BG in 15 minutes and repeat steps if
needed

145
Q

Management of Hypoglycemia: Unconscious Patients at Home

A

Injection of 1 mg of glucagon IM

After injection may take up to 20 mins for pt to regain consciousness
-Follow w/15 g of concentrated carbs & a snack

146
Q

Management of Hypoglycemia: In the hospital or
ER for patients who are unconscious, NPO,
or cannot swallow

A

Administer 25-50 cc of Dextrose 50% – ( D50, D50W)
IV Push
-Effect seen in minutes

147
Q

Which pharmacological treatment for hypoglycemia is used inside the hospital setting?

A

Dextrose 50% (D50, D50W)

148
Q

Which pharmacological treatment for hypoglycemia is used outside the hospital setting?

A

Glucagon

149
Q

Immediate Treatment for Hypoglycemia

A

The usual recomm is for 15-20 g of a fast-acting concentrated source of carbs

150
Q

Emergency Measures for Hypoglycemia

A

For those w/ glucose level <54 mg/dL, unconscious & cannot eat:

Admin 1 mg IM/SQ injection of glucagon

151
Q

Patient Teaching Considerations for Hypoglycemia

A

Hypoglycemia is prevented by:
-A consistent pattern of eating
-A consistent pattern of insulin administration
-Between meal and bedtime snacks
-Eat additional food when physical activity is increased
-Routine blood glucose tests

Wear a bracelet stating they have diabetes

Carry a form of simple sugar at all times

Having family members/friends be able to
recognize symptoms and actions

152
Q

Management of Diabetics in the Hospital

A

Prolong stay: increase infection rates, increase mortality

Stress & Infection increase blood glucose

BG targets: 140-180 mg/dL
Insulin treatment preferred
Protocols for insulin dosing

Appropriate Timing: Blood checks, meal consumption, insulin dose

153
Q

Sick Day Rules

A

During periods of physiologic stress BG levels increase

NEVER eliminate insulin
-Extra short acting insulin

Small portions of carbs

Check blood glucose & ketones: Every 3 to 4 hours
-Report Elevated BG or +ketones to provider

Drink fluids every hour w/ vomiting/diarrhea
-If ketones are present unable to keep down
fluids, hospitalization may be necessary

Want to prevent DKA
and coma in Type 1

154
Q

Nursing Considerations for Diabetics Undergoing Surgery: Pre-Op

A

Requires frequent BG monitoring (every one to
two hours)

For pts taking insulin:
-Morning of surgery all subq
insulin maybe held unless
BG>200 or half the usual
dose of insulin may be
given per provider orders

-If you don’t have orders to
hold insulin: contact the
healthcare provider

Pts taking metformin may be
instructed to discontinue the oral
agent 24-48 hours before surgery

155
Q

Nursing Considerations for Diabetics Undergoing Surgery: During Surgery

A

Blood glucose is controlled via IV infusion of regular insulin & dextrose infusion
-May come back on an insulin infusion

156
Q

Nursing Considerations for Diabetics that are NPO

A

Insulin dosage has been addressed by health care provider

Changes may include:
-Eliminate rapid-acting insulin
-Giving 1/2 usual dose intermediate acting insulin

IV dextrose may be admin to prevent hypoglycemia

To avoid problems these patients should be
scheduled for diagnostic tests and procedures
early in the morning

While NPO, the scheduled time for glucose
testing and insulin administration should still
match mealtimes

157
Q
A
