4 Cardinal Signs of DM:

A
  1. Polyuria (w/ glycosuria) – due to increase glomerular filtration of glucose

Q

Characterized by the destruction of the beta cells in the pancreas that usually leads to
absolute insulin deficiency

a. Immune mediated DM results from auto immune destruction of the beta cells

b. Idiopathic type 1 refers to forms that have no known cause

Q

A case between “normal” and “diabetes” in what the body is no longer using and/or secreting insulin properly

a. Impaired fasting glucose- a state when fasting plasma glucose is at least 110 but under 126mg/dl

b. Impaired glucose tolerance – a state when insulin of the oral glucose tolerance test are at least 140 but under 200mg/dl in 1-hour sample

A

Impaired glucose homeostasis

Q
  • Decrease in insulin requirements after passage of
    placenta
  • Non breastfeeding mothers- insulin- CHO balance returns
    in approximately 7 to 10 days
  • Breastfeeding mothers- insulin requirements remain low

Q

What do we take during Physical Examination

A

*Baseline ECG should be obtained

*Evaluation for retinopathy

*Weight and BP monitoring

*Fundal height should be measured

16
Q
  • Recommended between 24 and 28 weeks gestation
  • The woman should ingest 50g of oral glucose solution.

*One hour later a blood sample is taken.

A

Glucose Challenge Test (GCT)

17
Q

Glucose Challenge Test (GCT):

*If the result is ____ mg/dl or greater, a 3-hour oral glucose tolerance test is recommended.

  • Some practitioners use a lower cutoff of ___ or ___ mg/dl to identify more women at risk.
A

1.) 140mg/dl

2.) 130 or 135mg/dl

18
Q
  • The woman must fast from midnight on the day of the test.
  • The woman should ingest 100g of oral glucose solution.
  • Plasma glucose levels are then determined at 1, 2, and 3 hours.
A

*Oral Glucose Tolerance Test (OGTT)

19
Q

the diagnosed if the fasting blood
glucose level is abnormal or if two or more of the following values occur on the OGTT:

*Fasting > 95 mg/dl
*1 hr. > 180 mg/dl
*2 hrs. > 155 mg/dl
*3 hrs. > 140 mg/dl

A

Gestational diabetes

20
Q

Monitoring a Woman with Diabetes:

A
  • A woman should use a home test kit to determine if she is pregnant at the earliest possible time
  • The measurement of glycosylated hemoglobin is used to detect the degree of hyperglycemia present.

*HbA1c is measured.

*Ophthalmic examination

21
Q

S/Sx of Maternal Hypoglycemia

A
  • Shakiness (Tremors)
  • Sweating
  • Pallor; cold, clammy skin
  • Disorientation; irritability
  • Headache
  • Hunger
  • Blurred vision
22
Q

S/Sx of Maternal Hyperglycemia

A
  • Depressed reflexes
  • Drowsiness, headache
  • Rapid, deep respirations, acetone breath
  • Polyuria
  • Dry mouth, polydipsia

  • Fatigue
23
Q

Antepartal Nursing managment

MAJOR GOALS:

A
  1. To maintain physiologic equilibrium of insulin
    availability and glucose utilization during
    pregnancy
  2. To ensure an optimally healthy mother and
    newborn
24
Q

5 Antepartal Nursing Management:

A

1.) Dietary Regulation (Simple sugars should be eliminated)

  1. Exercise
  2. Blood Glucose Monitoring
  3. Insulin administration
  4. Evaluation of Fetal Status
