Q

How does Adrenocorticotropic Hormone (ACTH) work?

Q

What effect do Epinephrine and Norepinephrine have on the body?

A
  • Act on alpha one, beta one and beta two receptors
  • Increase the heart rate, increase the force of cardiac contraction, bronchodilation, vasoconstriction of peripheral arteries, vasodilates skeletal muscle arterioles, tells the liver to convert glycogen to glucose for energy (increased blood sugar)

Q

Explain what happens within the body in Type Two Diabetes Mellitus

A

  • Beta cells are decreased
  • Beta cells aren’t as responsive when glucose levels are elevated, therefore they will not release as much insulin as quickly

> 450 mg/dL

81
Q

What is a normal Hemoglobin A1C (Hgb A1C)?

A

< 5.7%

82
Q

If the glucose results higher than normal, the first thing the nurse should do is…

A

Assess the patient!

83
Q

If the glucose results higher than normal, the second thing the nurse should do is…

A

After assessing the patient, inquire about the patient’s dietary habits for the day. Have they eaten recently?

84
Q

What will kill the patient first, a critically high or critically low glucose?

A
  • Critically low!
  • Brain requires glucose for energy. Without glucose, the brain will shut down and the body will go into a coma (life threatening!)
85
Q

If a provider wants to see how well the glucose has been controlled over the past two to three months, what lab will be ordered?

A

Hemoglobin A1C

86
Q

A Hemoglobin A1C less than what number is ideal for a patient with Diabetes Mellitus?

A

< 7 %

87
Q

If a Hemoglobin A1C is > 9 %, what does the provider know?

A

The blood glucose has been very poorly controlled over the past two to three months

88
Q

If a patient has a glucose level of 80 mg/dL but a Hemoglobin A1C of 14%, will they have s/s of hyperglycemia?

A
  • No

- Glucose level is within range so s/s should not be present

89
Q

A Hemoglobin A1C of _____% or higher is indicative of diabetes.

A

6.5

90
Q

A Hemoglobin A1C of _____% is indicative of pre-diabetes.

A

5.7 - 6.4%

91
Q

If a patient is diagnosed with pre-diabetes, how will they manage the disease?

A
  • Diet, exercise, weight loss

- When done properly, they can avoid the diagnosis of Diabetes Mellitus

92
Q

What is pre-diabetes?

A
  • Condition in which blood glucose levels are higher than normal, but not high enough for a diagnosis of diabetes
  • DMII is developed within 10 years without preventative measures
93
Q

What is gestational diabetes?

A
  • Diabetes developed during pregnancy
  • Will usually return to normal glucose levels within six weeks postpartum
  • Increased risk for developing Type Two Diabetes
94
Q

What are acute complications of Diabetes Mellitus? What is most concerning?

A
  • Hypoglycemia
  • Hyperglycemia
  • Ketoacidosis

-Hypoglycemia is the most concerning, it can kill a patient first

95
Q

What increases insulin sensitivity and is an essential part of diabetes management?

A

Exercise

96
Q

Nutritional therapy and education should be _____?

A

Individualized

97
Q

What should the nurse include in their nutritional therapy and education?

A
  • Patient should not eat whatever they want and use insulin to “cover the calories”
  • Everything in moderation
98
Q

List the benefits of exercise.

A
  • Lowers insulin resistance and blood glucose
  • Weight loss
  • Lowers triglycerides and LDL
  • Increases HDL
  • Improves blood pressure and circulation
99
Q

What education should the nurse provide in regards to diabetes and exercise?

A
  • Exercise 150 minutes/week
  • Eat before exercising
  • Do not exercise if hyperglycemic and ketones are present in the urine
  • Hypoglycemia can occur up to 48 hours after exercising
  • Bring a snack to prevent hypoglycemia
  • Caution patient about injecting insulin into a site that is to be exercised
100
Q

Why should a patient not inject insulin into a site that is to be exercised?

A

-Increase the rate of absorption and speed the onset of insulin action

101
Q

What education should the nurse provide in regards to diabetes and illness?

A
  • Blood sugar can rise even if they do not eat or drink anythin
  • Continue to take insulin and diabetes pills as usual
  • Test blood sugar more frequently
  • Drink plenty of fluids
102
Q

What is the drug class for Metformin (Glucophage, Fortamet)?

A

Biguanide

103
Q

- Fortamet

105
Q

What is the generic name for Glucophage or Fortamet?

A

Metformin

106
Q

How does Metformin (Glucophage, Fortamet) work?

A
  • It decreases the glucose produced by the liver

107
Q

Does Metformin (Glucophage, Fortamet) directly decrease blood sugar? Is there a direct risk for hypoglycemia?

A
  • No it does not
  • It does not increase insulin production or release
  • No direct risk for hypoglycemia
