Q

How does pregnancy affect fluid?

How does pregnancy affect weight?

A

Pregnancy can cause in an increase of edema from fluid but this should be below the knees. If it is higher , than this could be an issue with something else going on.

Hypercoaguable state so more clots

Put mom on heparin or Lovenox to SQ since they are easy and inexpensive and can be self administered
Can be put on Aspirin as well but it is weaned off before delivery

Avoid Warfarin for the first trimester

Eat consistently when it comes to green, leafy foods due to Vit K , so they don’t counter act their medicine

Q

What to monitor with medication for women with heart disease?

A

Peak and trough levels

And monitor vit k

29
Q

When is CHF likely to peak?
What stimulates or causes the heart failure?

treatment for CHF?

A

24-32 weeks
but infection, severe anemia, or gestational hypertension can stimulate this

Diuretics and digitalis

30
Q

How does CHF affect the fetal risks?

A

Fetus can be SGA or premature delivery from impaired placental perfusion and nutrition.
- the s/d ration done may mean they need to be delivered early

31
Q

How can you minimize physical exertion during labor for women with CHF and therefore help o2 levels?

Will you use stirrups?

A

Don’t have mom walk around; keep her in bed
HOB elevated
Side lying position
O2 mask 8-10 L (bc we are mouth breathers)

No stirrups! The bending of the knee reduces oxygenation due to compressed popliteal veins

32
Q

When is regional anesthesia given to women with CHF?

A

Regional block given early to avoid more stress on heart and increased oxygen consumption due to pain

33
Q

What should the nurse monitor of a mother who has heart issues rt CHF during the labor?

A

Monitor blood gases, oxygen sats, vitals, and they can even do an EKG during labor

34
Q

What are operative options that can be used with the goal to speed up delivery and decrease stress for mom with heart issues rt CHF?

A

Vacuum or forceps

35
Q

Which classes of heart disease may be able to labor?

Class 1, 2, 4

Class 4 will probably need c section

36
Q

What is so important about first 48 hours after delivery?

A

The fluid shifting occurring due to loss of placenta’s hormones bc blood shifts to ECF to vascular space
Cardiac output increases

37
Q

Why is it good to have a family member or support person there with women with heart issues rt CHF in postpartum ?

A

Mom will be exhausted and more so than the average woman. She will need assistance

38
Q

A

Stool softeners so she isn’t straining

Antibiotics but only if she has a possible infection

39
Q

In postpartum.. will mom with heart failure be able to breastfeed if she is on diuretics?

A

No she shouldn’t. If there’s any medications she is taking they need to be evaluated though.
If she is set on breastfeeding but the meds at the given time won’t allow for it , she can pump and dump.

Otherwise, she can breast feed as long as she isn’t on any meds. The meds are the issue .

40
Q

A mom with heart failure asks how long she has to stay in hospital in postpartum. What do you tell her?

What education do you need to give for when she goes home?

A

She might have to stay longer bc of her condition.

There needs to be somewhere there for her assistance bc she will be so tired.

41
Q

What type of BC can mom with heart failure use?

A

Avoid estrogen based and that is it.

  • Can use progestin only
  • Deprovera shot is ok
42
Q

With anemia, how does the heart try to compensate?

A

HR increases tachycardia

43
Q

In PG why does H&H tend to drop in pregnancy just naturallu?

A

Due to blood volume increase. BUT, in women who don’t take their iron or prenatal vitamins the anemia is way worse

44
Q

What labs indicate anemia?

A

Hemoglobin below 11
Hematocrit below 33%

Most women hover over these levels tho

45
Q

How does anemia affect your oxygenation?

A

Anemia decreases oxygen carrying capacity and so the heart has to work harder to make up for it
(hence the tachycardia)

46
Q

Anemia risks of pregnancy to mom and baby?

A

Spontaneous abortion ; sab
early Preterm labor risk
small SGA infant
Post partum hemorrhage

47
Q

Types of Anemia?

A

Iron deficiency
Folate deficiency
Sickle cell anemia
Thalassemia

48
Q

How do they diagnosis iron deficiency anemia?

A

Ferritin levels will be lower than 12 mcg
Low Hematocrit below 33%
Low hemoglobin below 11

49
Q

What is the main type of treatment for iron deficiency anemia?

A

It is actually more preventative with nutrition.

  • iron supplement beforehand
  • iron transfusions later
  • blood transfusions later
50
Q

T/F

If you are iron deficiency anemic, you are more susceptible to infections

iron deficiency Anemic women tend to have plenty of energy

iron deficiency Anemic women will tend to have more painful labors

A

Women with anemia are more at risk for infections

Anemic women are actually tired most of the time

Anemic women’s labor is more painful bc their uterus becomes more hypoxic

51
Q

T/F

iron deficiency Anemic women have decreased risk of PPH

iron deficiency Anemic women have increased risk of pre-eclampsia

A

Anemic woman sure are at risk of PPH and bad outcomes due to lower reserves to begin with

Anemic women have increased change of high bp with protein spilling (pre-eclampsia)

52
Q

What is a folate deficiency specifically?

A

Not getting enough vit B(folate) but we do replace it with folic acid

53
Q

Why do we need folate/folic acid?

A

RNA and DNA synthesis

without it, you can have neural tube defects or lower extremity issues

54
Q

List some neural tube defects associated with not enough folate
Lower extremity issues?

A

Spine bifida
Meningoceal

clubbed foot

55
Q

How does folate deficiency affect rbcs?

A

Immature rbcs won’t divide and so they will be large or Macrocytic
(megaloblastic anemia)

56
Q

List some uncomfortable maternal symptoms mom may experience with low folate

A

Nausea
Vomiting
Anorexia

57
Q

How to prevent folate deficiency anemia?

What does mom take to treat her folate deficiency if she already has it?

A

Take folic acid as instructed! 0.6mg

If mom is already in the anemic stage, 1 mg folic acid daily with iron supplements

58
Q

What does mom’s diet need to be like if she has folate deficiency?

A

Water soluble fruits and veggies, Eggs, Legumes, Whole gains

59
Q

What do we recommend for women in general when it come to preventing folate deficiency?

A

Take folic acid and iron anyways

60
Q

What is sickle cell again?

SS

Ss

A

Abnormal SS hemoglobin that is shaped wrong and causes obstruction

SS= disease

Ss= trait

so you need to have both be SS for it to really affect you in pregnancy

61
Q

What is the issue with the SS disease in pregnancy?

What is lifespan in rbc SS?

A

hypoxia
sickle cell crisis leading to clot

Lifespan is shorter . 5-10 days. And that really causes the anemia too

62
Q

How to treat the sickle cell exacerbation ?

Triggers- 
dehydration
infection
hypoxia
acidosis
A

Rehydrate her
Get oxygen
Give antibiotic
Pain analgesics bc the hypoxia can be painful

63
Q

How to manage sickle cell anemia during labor?

Labor position?

A

O2 administration
FHR monitoring
Side-lying
Regional block earlier on

64
Q

Fetal risks from sickle cell anemia?

A

Preterm
IUGR

but you need to follow up w ultrasound

65
Q

What is Thalassemia anemia ?

A

Insufficient amount of hemoglobin to fill the RBC’s from abnormal alpha or beta chains that is hereditary

66
Q

If they are a heterozygous Thalassemia anemia or one gene - does it effect pregnancy too much?

What if they are homozygous Thalassemia or both genes?

A

No not really

When both genes are the problem they have the disease and these people have trouble even getting pregnant but sometimes they still do

67
Q

How does Thalassemia anemia in mom affect the baby?

A

At birth baby won’t be affected. It is over time as they grow up the issues arise

68
Q

Why is it that women with Thalassemia anemia don’t get pregnant?

A

They often die before they are of childbearing years and are often infertile.
The minors are the ones who live
