Q

Maternal complications associated with diabetes

A

Hydramnios rates 10x greater (>PROM)
Infection rates higher (UTI and yeast)
Ketoacidosis can = fetal death

21
Q

Preconception counseling for diabetes

A

Parter should be involved
FInances considered
Contraception issues require attention an dteaching
Type 2 DM pts. and Gestational diabetes can safely take on Glyburide, a sulfonyurea agent, or SQ insulin. Other agents cross placena and may be teratogenic

22
Q

Fetal and neonatal complications r/t gestational diabetes

A
  • Stillbirth >36wks
  • Congenital anomaly 6-10% per pregnancy with cardiac, CNS, and skeletal most common
  • Macrosomia >4000 gm, birh injuries, C/S
  • IUGR r/t maternal vascular disease and increased risk for BDS
  • Neonatal hypoglycemia, F&E imbalances, hyperbilirubinemia, and polycythemia
23
Q

Sulfonylureas stimulate _______ production

A

Insulin

24
Q

Insulin needs during pregnancy

A
  • Lower in 1st trimester d/t increased production by pancreas and increased peripheral insulin sensitivity
  • Increased in the 2nd trimester d/t maternal hormones acting as insulin antagonists
  • Dramatic increases by 3rd trimester
  • Levels off at 36 wks
  • By delivery, maternal needs significantly drop
25
Q

MSAFP

A

Found in both fetal serum and also amniotic fluid

  • Pursue potential medical interventions
  • Begin planning for a child w/ special needs
  • Start adressing anticipated life changes
  • Identify support groups
  • Make a decision about carrying child to term
26
Q

Blood glucose monitoring during pregnancy

A

Key to control

Daily urine ketone checks to pick up on ketoacidosis early on

27
Q

Normal blood glucose during pregnancy

A

60-120 mg/dl

28
Q

Fetal non-stress test

A

Simple, non-invasive test performed in pregnancies >28 wks gestation

29
Q

When is a fetal NST done?

A

If baby not moving like usual
If overdue
If suspect placenta is not functioning adequately
If high risk for any reason

30
Q

What can a fetal NST indicate?

A
  • Baby is not recieving enough O2 because placental or umbilical cord problems
  • Fetal distress
31
Q

HbA1C

A

Blood glucose attatches to a hemoglobin in the RBCs
RBCs live 3 mos
When HGB/RBC is measured, it reflects average BG for prior 2-3 mos

32
Q

What is the normal HbA1C?

A

4-6%

33
Q

What level of HbA1C is diagnostic of diabetes?

A

> 6.5%

34
Q

When might an HbA1C be inaccurate?

A

If pt. is also anemic

35
Q

How often should HbA1C test done?

A

Q 3 months

36
Q

When is a contraction stress test done?

A

At 34 wks

37
Q

Contraction stress test

A

Oxytocin given IV
Monitor HR and contractions
O2 levels may drop, causing HR to drop

38
Q

Biophysical progile (BPP)

A

Measures baby’s HR, muscle tone, movement, breathing, and the amount of amniotic fluid

  • NST
  • Fetal ultrasound
39
Q

Teaching for diabetes during pregnancy?

A

Decrease stressors- need strict daily routine
Diet = 3 meals, 3 snacks, never skip
Acitivty= mild exercise
Insulin = appropriate dose to maximize glucose levels and reduce hypoglycemia
Rest= set sleep schedule; planned rest
BG = Keep between 60-120 depending on meals and time of day

40
Q

Fetal surveillance

A

EDD established
Measure MSAFP between 16-18 wks d/t high rate of neural tube defects
Fetal echo to detect cardiac problems by 22 wk
Beginning at 28 wks, NST weekly
In presence of non-reactive NST, order a CST or BPP

41
Q

Nursing care of pt. with diabetes who is pregnant: History

A
Age diagnosed
Glycemic control
Diet and activity
Insulin use
Medical and OB Hx
42
Q

Nursing care of pt. with diabetes who is pregnant: Assesment

A
Knowledge base
Motivation
Support systems
S&S
Weight 
Labs (UA, urine C&S, BG, Hgb, A1c)
43
Q

____% of gestational diabetics develop DM later

A

50%

44
Q

When is gestational diabetes usually diagnosed?

A

in the 2nd and 3rd trimester as maternal intake and pregnancy hormones increase insulin resistance

45
Q

Risk factors for gestational diabetes

A
Prior deliveries >4500 gm
>25 yrs
Obesity
Family hx of type 2 DM
Polyhydramnios
Unexplained stillbirth
46
Q

Glucose tolerance test

A

BG measured at intervals after the pt/ drinks a concentrated carbohydrate drink
GTT- high risk women initially and 24-28 wks
BS >139 goes to 2 hour GTT

47
Q

Management of GDM

A

Managed like type 1 or 2 wirh focus on glycemic control
Diet and exercise (usually)
Less likely to require c/s

48
Q

If you have GDM, it is typical in future pregnancies with an _____ onset

A

Earlier
