Q

DM pathophysiology:

A
  1. fetal demands - baby pancreas takes over -too much sugar- kicking out sugar to control moms hyperglycemia. We dont want the baby to work that hard.
  2. role of placental hormones
  3. changes in insulin resistance
  4. effects on mom
  5. effects on fetus

Q

DM Therapeutic Management

A
  1. preconception counseling: want mom to start out as healthy as possible.
  2. blood glucose level control (HbA1c < 7%) - if mom is known diabetic/ previous gest. diabetes then we want her HbA1c below 7.
  3. glycemic control
  4. nutritional management: want pt to see doc, NP, dietician
  5. hypoglycemia agents
  6. close maternal & fetal surveillance
  7. management during L&D: need to do blood sugar checks EVERY HOUR
  8. early induction 38-39 wks

Q

DM Screenings

A

-at first prenatal visit (fasting glucose)
-additional screening at 24-28 weeks for women considered at risk (fasting glucose + GTT if elevated)

fasting blood glucose level: less than 95mg
1 hr: less than 140mg
2 hr: less than 120mg
3 hr: less than 95mg

if above any of those #s then may be diagnosed w/ gest diabetes

-s/s of cardiac decompensation

21
Q

C&A Heart Disease: Nursing Management

A
  1. stabilization of hemodynamic status - may need to be at the hospital the whole time
  2. risk reduction measures: education/counseling/support - decrease stress & eat right
  3. cardiac meds if prescribed
  4. energy conservation; nutrition - may not be able to work or do their normal routine
  5. fetal activity monitoring
  6. s/s of cardiac decompensation - labor can put them into decompensation
  7. monitor during labor
22
Q

Asthma Meds

A

budesonide
albuterol
salmeterol

23
Q

Asthma

A

check: asthma triggers; lung auscultation

manage: do client education, oxygen saturation monitoring during labor

24
Q

If mom is Status Asthmaticas then baby is…

A

baby has low amniotic fluid bc uterus is not getting oxygen so then baby is not getting enough oxygen - kidney not getting blood = not producing urine = baby not getting enough amniotic fluid

25
Q

Iron Deficiency Anemia Caused by:

A

-due to inadequate dietary intake

manage by: eliminate s/s, correct deficiency, replenish iron stores
prenatal vitamins & iron supplement

-give mom stool softener bc prenatals & extra iron will make her constipated

26
Q

Iron Deficiency Anemia S/S:

fatigue
weakness
malaise
anorexia
susceptibility to infection (frequent colds)
pale mucous membranes
tachycardia
pallor

27
Q

Iron Deficiency Anemia: Abnormal Lab Results

low hemoglobin
low hematocrit
low serum iron
microcytic and hypochromic cells
low serum ferritin

28
Q

Sickle Cell Anemia is:

31
Q

Sickle Cell Anemia Management:

A

-need lots of f/u appts, blood testing
-labor is difficult for them bc already in pain and then add labor pain
-dont want her bleeding too much, need to keep RBC
-increased risk for blood clots

Labor: rest, pain mgmt, oxygen, IV fluids, close FHR monitoring

PP: antiembolism stockings, family planning options

32
