Test #4 Flashcards
(374 cards)
What is Veal Chop? How can we use it?
Used to help interpret fetal strips:
V = variability
C= cord compression
E = early decelerations
H= head compression
A = accelerations
O = Ok (what we want to see)
L = late decels
P = placental insufficiency
What classifies as obesity
BMI at 30 or above pre-pregnancy
What things are we worried about with an obese mom? 4
- Bleeding (have hemorrhage kit ready)
- Difficult to monitor baby
- Difficult to help change patients position if needed
- Anticipate large babies (LGAs - large for gestational age) creates issues during delivery
What does IUGR stand for
Intrauterine growth restriction
Would we always expect a large baby from an obese mom?
No - there may be other comorbidities, like mom is a smoker, that causes issues with perfusion with the placenta, which can lead to IUGR and smaller babies
Before birth, what are complications of obesity 3
- Diabetes
- HTN leading to preeclampsia
- Sleep apnea
During birth, what are complications of obesity 4
- Macrosomia (large baby)
- Prolonged labor
- Shoulder dystocia (increased C-section rates)
What are some risks for C-sections for obese women 4
- Increased risk of BLEEDING
- Increased risk of infections
- Delayed wound healing (increased risk for dehiscence)
- Thromboembolism (all pregnant women are at an increased risk, but being obese increasing this risk factor even more)
Why is there an increase of bleeding for obese mom’s
It can be difficult to do a proper fundal massage with the extra tissue
Later on in life, what are children who are born from an obese mother at risk for 2
- Increased risk of childhood obesity
- Increased risk for chronic conditions (like diabetes)
What are our nursing considerations for obese mom’s 5
- Weight gain through their pregnancy should be smaller (so we only want them to gain around 11-20 pounds)
- Early testing for gestational diabetes due to their increased risks
- More frequent prenatal visits
- Anticipate more challenges in labor and delivery (have hemorrhage kit ready)
- Issues with babies maintaining blood sugars after delivery
Why are we seeing an increase in CVD in our mom’s
2 main factors:
- Women are having babies when they’re older
- Underlying preconception comorbidities like obesity, HTN, diabetes, rheumatic heart disease if strep is not treated
What population of women is more likely to have untreated strep
Immigrant populations with lower socioeconomic status
Why do we consider pregnancy the ultimate stress test in terms of CV health 4
- Dramatic increase in blood volume, especially during 3rd trimester (up to 50% increase)
- Increase in HR that naturally happens
- Decrease in systemic vascular resistance (naturally), that can cause dilation in your legs, which can lead to pooling of blood and risk for DVTs
- Increased coagulability
If a pt is at an increased risk of coagulability, possibly from CVD, what two medications might they be on?
- Baby aspirin
- Heparin
What anticoagulant drug do we NEVER use during pregnancy (carries a black box warning - category D)
Warfarin (can cross the placenta and cause baby’s blood to thin)
What sucks about having CVD while pregnant?
Normal pregnancy symptoms can be made even worse by CVD, like:
- Increase in fatigue caused by anemia and changes in cardiac output and BP
How can CVD impact a woman’s labor 2
- During a contraction, blood is shunted away from the placenta and out into the mom’s cardiovascular system, which can be up to 500mLs of extra blood going out into the system. This can put a lot of strain on a woman’s cardiac system taking in this extra blood and increasing her cardiac output.
- Contractions are painful and can increase BP and HR, which can then increase cardiac output
How can we care for our CVD pts during labor 3
- Strict Is and Os (don’t give any extra fluid, which can increase mom’s fluid volume and increase her CO).
- Close monitoring of mom and baby (might also have telemetry on mom)
- Want effective pain relief to help decrease CO and to help shorten second stage
What is second stage? Why would we want it shortened for moms in labor? What can we do to help?
Second stage is when mom is pushing, so when a mom with CVD is bearing down and pushing, this can increase their BP and HR, which increases their CO… So we don’t want to put this kind of stress on their heart for very long, so we want to try and shorten this stage.
These women are great candidates for laboring down, which, with an epidural, is when a women lets her uterus do some of the work when she is 10cm and 100% effaced, where the women isn’t pushing, and instead the uterus is passively moving baby along, this helps take off some of the pushing duties for our CVD moms
What acronmyn can help us remember what infections women should avoid during pregnancy
TORCH (teratogenic - cross placenta can cause fetal abnormalities or other complications during pregnacy). We screen for these.
T = toxoplasmosis (kitty litter and uncooked meat)
O = other infections like chicken pox, syphilis, HIV, parvo virus, chlamydia, Hep B)
R = rubella
C = cytomegalovirus
H = herpes simplex
What is important about rubella
We screen for it and have a vaccine for it, but we can’t give the vaccine until after pregnancy, because it’s a live virus vaccine (one of the few live virus vaccines we have left)
Besides screening for TORCH infections, what other infections do we screen for?
- Hep B
- HIV
- GBS (group beta strep) (screen towards the end of pregnancy, because most adults who have it will be asymptomatic, but it can cause newborns to have sepsis if not treated, so we like to screen for it and treat prior to delivery) (GBS positive or GBS status unknown, we treat with antibiotics during labor to help reduce transmission with a vaginal delivery)
- UTI (big deal in pregnancy because they may be asymptomatic during pregnancy, so will screen for it just in case they have it but are not showing symptoms)
Why are we worried about UTIs during pregnancy
They can cause pre-term labor and progress to pyelonephritis (so we want to catch these UTIs early so we can prevent any complications)
