What is cardiac care for class IV?

Bedrest
Prob can’t go to term
C/s will likely be needed bc process of pushing=too much on heart

Perfectly

T/F Pregs can go from Class I or class II to class III or IV during pregnancy

True–this is due to the CO increases and more stress being placed on heart

Why is mag sulfate given?

What does mag sulfate work on?

Large smooth muscles (so also slows down UC, reduces BP, slows down everything!)

Perfectly

What are signs of mag toxicity?

Absent DTR

Slurred speech
Severe muscle weakness
Cardiac arrest
Low UO

Perfectly

What is antidote for mag sulfate toxicity?

Calcium gluconate

How well did you know this?

Not at all

Perfectly

What if pt. has mag sulfate toxicity?

- Give calcium gluconate (we can't do this tho) - Intubate if not breathing - Keep side rails up - Keep lights dimmed and quiet environment

Why can't we (nurses) give calcium gluconate?

This drug can cause arrhythmias so doc has to give it bc he/she needs to be available if that occured

What is a therapeutic level of mag sulfate?

4-7 mEq/L

What s/s would woman experience while on mag?

- Flushed, hot - Sedated - Nausea - May experience burning at IV site especially during bolus

What is BP in mild pre-ecl?

140/90 or greater

What is BP in severe pre-ecl?

160/110 or greater

What are some cardinal sings of pre-ecl?

- Elevated BP - Proteinuria 2+ on dipstick or greater - NV - Periorbital edema - Visual disturbances/ dizzy

What are some signs of eclampsia?

Seizures/coma

What is proteinuria level (not the 24 hour specimen)

30 mg or higher (1+on ds) in at least 2 urine specimens at least 6 hrs apart with no presence of UTI

What is proteinuria in the 24 hour specimen?

Concentration above 300 mg in 24 hrs; no presence of UTI

What can create a great risk for cardiac decompensation that is a normal adaptation in preg woman?

All pregs can 30-50% in CO by mid-preg. For the women with heart problems, this can cause a major complication due to the inability to maintain CO (cardiac decompensation)

How many weeks would be the ideal time for a change in CO?

Around mid preg (28-32 weeks)

What is cardiac decompensation?

Inability to maintain adequate CO

S/S of cardiac decompensation (subjective)?

- Increase in fatigue - Dificult breathing - Freq. cough - Palpitations - Generalized edema

S/s of cardiac decompensation (objective)?

- HR 100 or greater - Crackles in lungs - Orthopnea (increasing dyspnea) - 25 or greater RR - Cyanosis

For cardiac pt, what kind of monitoring is done intrapartum?

- Routine assessments and ones for cardiac decom - ABG may be needed to assess oxygenation - ECG monitor - Continuous monitor of BP and O2 - Continuous FHR monitoring!!!

During labor for cardiac client, what is the focus?

Promoting cardiac function is focus.. also need to minimize anxiety and give anticipatory guidance throughout labor to woman and fam

Labor of cardiac pt: support childbirth plan only to the point of it being _____

Feasible to cardiac condition

Labor of cardiac pt. What kind of comfit can we give?

Back massage

Labor of cardiac pt. | What positioning?

- Head and shoulders elevated and body parts resting on pillows - Side lying position is best for hemodynamics

Labor of cardiac pt. | What is the best labor for this type of pt?

Short and pain free - use pain meds - do epidural but avoid hypotension

Labor of cardiac pt. | What is best: vaginal or c/s birth

Vaginal---can be in side lying to facilitate uterine perfusion if needed

Labor of cardiac pt. | Why is c/s usually not recommended?

Dramatic fluid shifts, sustained hemodynamic changes, and increased blood loss compared to vag delivery

What drugs are contraindicated for cardiac pts?

Beta-adrenergic (terbutaline)

Cardiac pt. Why will mom get prophylactic antibiotic?

To prevent bacterial endocarditis

Cardiac pt. What does lanoxin do?

Increase contractility of heart

Cardiac pt. Are diuretics given?

NOT usually; this is a controversial issue

How is fetus affected by cardiac problems?

Circulatory changes can cause decreased uterine perfusion--spon. abortion, preterm labor or birth, IUGR

What h&h constitutes iron def. anemia?

Hgb less than 11 Hct less than 33

What are maternal symptoms of iron def. anemia (IDA)

- Pallor - Fatigue, lethargy - Headache - Pica habits

What are fetal effects of IDA?

Baby takes all iron and that can cause sever maternal anemia which causes reduced hgb and O2 so that means compromised baby

What are iron preg needs ?

30 mg

What increase iron absorption? decreases?

Increase: Vit C (melon, strawbs) Decrease: coffee, tea, milk

Why do we need folic acid?

- Formation of RBC - Cell duplication - Placental and fetal growth

Maternal symptoms of folic acid def (FAD)?

-Megaloblasts (large, immature erythrocytes)

What are fetal effects of FAD?

NTD

How much folate is needed for prego? lactating mom?

Preg: 400 mcg Lactating: 280 mcg

Autosomal recessive disorder that causes erythrocytes to assume an S shape clumping together occluding small BV

SCA

What 2 reasons why preg can precipitate Sickle cell crisis?

1. Jaundice r/t decrease bone marrow function and massive erythrocyte destruction 2. Pain r/t major infarcts in joints and major organs

Fetal effects of mom with SCA?

- Prematurity - IUGR - Fetal death during a SC crisis

What is therapeutic management of SCA?

- Good hydration and nutrition - Folate supplement - Rest periods - Prompt treatment for any illness or infection during preg

Normal H&H in a preg?

Hct: Greater than 33% Hgb: Greater than 11

What diet does IDA need?

Iron supplements | Iron rich food

What diet does FDA need?

Folic acid supplements - Dark green veg - Citrus fruits - Eggs - Legumes - Whole grains

What diet does SCA need?-

-Lots of hydration but avoid fluid overload

What is the major consequence of any anemia in preg?

Reduction of O2 capacity in blood--CO is then increased to compensate--CHF can result! *also can put woman at increased risk of infection due to increased blood loss
