25
Why does breast tenderness occur in early PG
Hormones cause this. Will feel this fairly early and it tingles
26
How early on can quickening be felt in early PG?
Can be felt at 16 weeks especially with multipara or moms with multiple PG past 20 weeks First moms may not know until 20 weeks
27
Probable signs of PG are noticed by who?
The medical professional or anyone doing the exam.
28
Goodells sign
Softer cervix probable sign
29
Chadwick
Blue-ish color of cervix due to increased blood flow probable sign
30
Hagar's sign
Softening cervix probable sign
31
Uterine enlargement
Cervix will appear larger probable sign
32
Braxton Hicks
Low amplitude intensity of cervix so it flies below pain perception. Need to be above 20-30 mmHg. Again, painless contractions. But they have a positive effect by stimulating growth & blood flow. Not strong enough to evacuate the uterus.
33
Uterine souffle
Maternal HR - not the HR of the fetus.
34
Why does pigmentation occur?
Occurs over time due to estrogen
35
Chloasma or melasma
When you have more melanin in your skin
36
Abdominal Striae
Stretch marks that happen later in PG
37
Ballottement
Baby should be moveable or to float (throughout PG too due to gravity free environment)
38
Linea Nigra
Vertical line down to pubis that can get darker (areola becomes darker too).
39
Is PG test a probably finding
Yes - bc other things can cause a positive test due to hormones. If you have a hormonal abnormality like hcg, you can get a positive test.
40
Palpation for fetal outline
Could be fibroids ??? 18:40
41
Positive signs of Pregnancy
These are signs that are only seen when you are for sure pregnant? Which doesn't really make sense but oh well.
42
List 4 positive signs of Pregnancy
Visualization - such as an ultrasound Fetal Heartbeat - beat that is different than moms, fetal EKG, or just externally demonstrate fetal HR Fetal movement **felt** by examiner after 20 weeks . Fetal movements **visible** to an examiner - often later in PG
43
When can visualization of the fetus occur?
Around 6 weeks - gestational sac Around 8 weeks - fetal parts, cardiac motion
44
When can you doppler a fetal HR? When can you do a fetoscope?
10-17 weeks for doppler fetoscope is after 16 weeks
45
How are your vascular and lymphatic systems affected by PG?
They will increase!
46
What fraction of maternal blood volume goes to the uterus?
1/6 - which is why women can lose a lot of blood
47
Rate of blood flow
450-650 ml/min at term
48
Does the uterus experience hyperplasia or hypertrophy?
Hypertrophy in order to accomodate the fetus and fluid.
49
How much does the uterus add in weight per term?
Starts at around 2 oz to 2.5 Ibs at term
50
What happens to uterus walls in pregnancy
Walls thicken
51
How to measure fundal heigh or McDonald's measurement
Top of uterus or symphysis pubis to top of fundus in cm with tape measurer
52
Fundal height at 12-14 weeks
at top of symphysis
53
Fundal height at 22-24 weeks
At the level of umbilicus
54
Fundal height at 36-38 weeks
xiphoid process
55
Fundal height at 40 weeks (or after lightening) What is lightening?
Below the xiphoid When the fetus descends into pelvic cavity to settle and drop below the xiphoid. Baby settles into the pelvic cavity & they are able to breath easier and the urinary frequency occur more due to bladder pressure.
56
When will a primiparas (never PG before) feel their lightening approaching? What about for multiparas?
Two weeks before delivery. You get a little bit of a warning. Women who have had multiple PG will feel lightening around labor
57
When does fundal height relate to age?
At 20 weeks. This helps us know the avg size of the fetus and the amount of amniotic fluid inside the placenta. It is a good measuring tool essentially & is accurate.
58
What is the operculum?
This is the mucus plug that forms in the cervix to keep ascending organisms from invading the uterus. Feels gelatin like or glob like. When you lose it, you'll just see a big blob of mucus. You may even feel it when it falls out in early labor.
59
Leukorrhea
Increase in mucus wetness but it is clear and odorless & related to pregnancy. So, not a sign of any infections. But people will come in & they'll have to be swabbed but its usually just PG changes. Your body is just washing away organisms.
60
Primary hormone responsible for breast changes in PG?
estrogen but progesterone does make some changes.
61
venous congestion
It is increased blood flow to the breasts really. Causes noticeable blood vessels && this has to do with breasts getting larger and warmer. Breasts may even tingle
62
Can you get striae on the breasts? Why?
Yes - stretch marks on breasts are common due to breakdown of collagen fibers which never repair themselves. Never repairs itself but after delivery will fade to a silver white due to loss of pigment.
63
Colostrum How early can it be produced. What about first time moms?
pre-breast pink that is creamy yellow. Can be produced as early as 4 months. First time moms will have it closer to birth but veteran moms will have it sooner due to leakage
64
What hormone is responsible for colostrum and breastfeeding in general?
Pro-lactin or the hormone responsible for lactation released after delivery of the placenta & progesterone levels drop which works as feedback to produce the breastmilk
65
How much does blood volume increase ? Why? When do increase blood vol symptoms previal the most?
40-50% Increase in blood volume is needed bc they lose a lot of blood in delivery. Between 28-34 weeks blood vol at greatest
66
How much do rbc count increase? Why is this relevant? What if there's a big drop?
30-40% of rbc increase so not same rate as blood volume. This leaves a gap lead to the hemodilution which results in psuedoanemia in PG. H&H will appear low but this is normal. However, if it is excessive, that means someone wasn't taking their iron.
67
Which ventricle increases in pregnancy? What about murmurs and palitpations? What next?
Left ventricle increases due to workload & volume increase. These are usually okay. No symptoms. But if they have chest pain or other symptoms, they need a cardiac consult. Most times its normal though.
68
How much will HR increse in PG? Why? What is the cut off HR?
10-15 beats for compensation 100 bpm is too high bc then you're tachycardic.
69
How does PG affect brachial readings? What position will make BP lowest? What position should you always avoid?
Highest in sitting position bc they are dangling. BP of orthostatic or recumbent positon is lower.
70
What position should you tell PG mom to avoid? And why?
Don't let them be supine or just laying down on the back. It will cause hypotension due to compression of the aorta to uterus & so less CO for fetus.
71
What is BP like per trimester? (1, 2, 3)) Should BP ever go up in PG?
1st - stable bp 2nd - subtle drop in bp 3rd - go bak up to stable bp No it should never raise. This could indicate eclampsia, diabetes.. etc
72
Due to compression of the iliac vein.. what can happen?
dependant edema below the knee and around ankle especially varicose veins around vulva and vagina which is more likely in high gravida moms hemorrhoids due to venous congestionfrom pressure of uterus
73
What happens to resistance of the systemic and pulmonary? How do we check for this outcome?
Resistance decreases which causes an increasd risk of pulmonary edema Listen to lung sounds, count respirations, 02 sat, coloring. Subjective respiratory complaints to check for pulmonary edema
74
You are checking your patients lab & you see an increase in wbc count. Should you assume infection?
No - the neutrophils increase just incase they need to be used. To rule out infection, look at the differential shift of all the cells bc basophils and rest will be low.
75
How are serum protein levels affected by PG? What are proteins a sponge for? When is this concerning?
Serum protein will drop due to the increase in blood volume. They become diluted and less concentrated. Proteins are a sponge for water. And so if proteins drop, the water goes with them into the extracellular compartment to cause edema. If edema is above the ankles it is a cause for concern. But anything below the knee is normal & often shifts very quickly.
76
PG mom says her shoes no longer fit. What do you tell her?
It is common to grow out of shoe size due to edema shifting the bones & may alter foot size after PG too.
77
What happens to coagulation in PG? What can this lead to? How much blood should you lose in labor? What clothing should you wear?
coagulation increases in order to protect from hemorrhage after delivery (PPH) but that means you are more prone to clotting! 5-6x more Less than 500cc Wear loose clothing when PG to avoid clot increase
78
Description of PG woman who is more likely to develop clots
A PG short, overweight, or sedentary will increase clot risk.
79
Treatment for hemorrhaging? route? half life?
txa or Translimic Acid given IV to slow the clot from breaking half life 1-3 hrs
80
Which side should we try to get mom to lay on?
left side BUT if the baby doesn't like it, the right is fine. This is due to the venous stasis that can occur bc the uterus causing pressure
81
vena cava syndrome
Compression reducing return and so CO decreases
82
Spider nevi or *Angiomos* description and cause Will they blanch?
Arteriole appearance that makes a spider web pattern on skin. Due to increased estrogen in blood. No they won't blanch due to them being blue. - will go away after PG
83
How does PG affect sweating?
Sweating will increase due to more waste being produced. You'll just need to shower more.
84
Blood flow to skin and nails \_\_\_\_\_.
increased blood flow. After delivery hair may fall out temporarily due to hormone changes.
85
What is hyperpigmentation change? What hormones involved? Who is more pronounced in?
When the skin has spots on it essentially. Due to melanin or melontropin and estrogen More pronounced in darker skin women who get sun exposure.
86
melasma
mask of pregnancy. cheek, nose , forhead
87
linea nigra
pigmented line from umbilicus to pubic area
88
Nipples and areola changes in PG?
they darken
89
Palmar erythema
pinkish blotches on palmar surfaces
90
striae gravidarum do you need anything fancy for these?
stretch marks due to loss of collagen and thus weakened connective tissue No - just use regular lotion.
