A

labor = contractions with cervical changes

contractions (regular or irregular) with cervix >= 3 cm (less than 3 cm is false labor)

36
Q

(SmartyPance)

what does parturition mean?

A

labor

37
Q

(SmartyPance)

what do we monitor for infant well-being during the birthing process?

A

Heart rate and the pattern is an indicator of infant well-being

38
Q

(SmartyPance)

what is the normal heart rate in a newborn?

A

120-160 bpm

39
Q

(SmartyPance)

what is an indication of fetal distress?

A

Consistent decelerations after a contraction can indicate fetal distress

40
Q

(SmartyPance)

what are two types of fetal monitors used during the birthing process?

A

External fetal monitor – on the maternal abdomen

Internal fetal monitor – electrode attached to the infants head

41
Q

(PPP 379)

STAGE I of LABOR:
define it
name and describe the two phases

A

STAGE I = onset of labor (true regular contractions) to FULL DILATION OF CERVIX TO 10 CM

LATENT PHASE = cervix effacement w/ gradual cervical dilation

ACTIVE PHASE = rapid cervical dilation (usually beginning at 3-4 cm)

42
Q

(PPP 379)

STAGE II of LABOR

define it

name and define the two phases

A

STAGE II = time from full cervical dilation until DELIVERY OF THE FETUS

PASSIVE PHASE = complete cervical dilation to active maternal expulsive efforts

ACTIVE PHASE = from active maternal expulsive efforts to delivery of fetus

43
Q

(PPP 379)

STAGE III of LABOR
define it

give three signs of placental separation

A

STAGE III = postpartum until DELIVERY OF PLACENTA (0-30 minutes usually, avg is 5 min)

Three signs of Placental Separation

  1. gush of blood
  2. lengthening of umbilical cord
  3. anterior-cephalad movement of the uterine fundus (becomes globular and firmer) after placenta detaches

(placental expulsion is due to downward pressure of the retroplacental hematoma, uterine contractions)

44
Q

(PPP 379)

what is sometimes called the 4th stage of delivery?

A

the period 1-2 hrs after delivery where mother is assessed for complications

45
Q

(PPP 379)

what are the 7 cardinal movements of labor?

A
  1. engagement (fetus enters pelvic inlet)
  2. descent (head passes into pelvis (aka “lightening”))
  3. flexion (fetus head flexion)
  4. internal rotation (fetal vertex moves so sagittal suture is parallel to AP diameter of pelvis)
  5. extension (vertex extends, passes beneath pubic symphysis)
  6. external rotation (fetus externally rotates after head is delivered so shoulder can be delivered)
  7. expulsion
46
Q

EARLY (aka LATENT)
ACTIVE
TRANSITION

A

Accelerations

Early decelerations

Variable decelerations

Late decelerations

52
Q

(SmartyPance)

describe “accelerations” in terms of fetal heart rate changes

A

accelerations = increase of baseline 15 bpm for 15 seconds –> response to fetal movement –> reassuring

53
Q

(SmartyPance)

describe “early decelerations” in terms of fetal heart rate changes

A

early decelerations = mirror images of contractions –> fetal head compression –> benign

54
Q

(SmartyPance)

describe “variable decelerations” in terms of fetal heart rate changes

A

variable decelerations = rapid FHR drop wtih a return to baseline with variable shape –> cord compression –> benign if mild or moderate –> worrisome if severe

55
Q

(SmartyPance)

describe “late decelerations” in terms of fetal heart rate changes

A

LATE DECELERATIONS = FHR drop at the end of contraction –> uteroplacental insufficiency –> ALWAYS WORRISOME

56
Q

(SmartyPance)

stronger

57
Q

(SmartyPance)

↑ vascularity → purplish-blue color

Mild softening due to edema, hyperplasia (Goodell’s sign); ↑ softening in third trimester

58
Q

(SmartyPance)

A

Develops where embryo attaches to uterine wall

Expands to cover 50% internal uterine surface

Functions as maternal-fetal organ for metabolic, nutrient exchange

Secretes estrogen, progesterone, relaxin, hCG

59
Q

(SmartyPance)

physiology of pregnancy: vaginal changes

A

↑ vascularity → bluish-purple color

Loosening of connective tissue → ↑ distensibility

Leukorrhea

pH of 3.5–6.0 → protects against bacterial infections

60
Q

(SmartyPance)

physiology of pregnancy: breast changes

A

↑ size, weight, nodularity, blood flow, vascular prominence

↑ activity of Montgomery’s tubercles (sebaceous glands)

Progesterone ↑ alveolar-lobular development; prevents milk production during pregnancy (inhibits prolactin)

Estrogen ↑ growth of lactiferous ducts

Secretion of colostrum begins week 16

61
Q

(SmartyPance)

physiology of pregnancy: C/V changes

A

Mild hypertrophy

↑ heart rate by 15–20 beats/minute

Stroke volume ↑ 30%,
cardiac output (CO) ↑ 30-50% (by term);
↓ BP due to progesterone-induced vasodilation;
BP = CO × systemic vascular resistance (SVR)

Supine hypotensive syndrome

Gravid uterus elevates pressure veins draining BLE → slowed venous return, dependent edema, varicose veins, hemorrhoid

62
Q

(SmartyPance)

increase blood volume

total RBC volume goes up ~30%

increase WBC count (5,000 - 12,000/mm3) (nml = 4,500 - 11,000?)

increase clotting factors

63
Q

(SmartyPance)

increase tidal volume 30-50%

gravid uterus = pressure on diaphragm

hyperventilation

mild resp alkalosis

estrogen-induced edema in nose = congestion, epistaxis

64
Q

(SmartyPance)

physiology of pregnancy: GI changes

A

Progesterone-induced smooth muscle relaxation, delayed gastric emptying, ↓ peristalsis → nausea, vomiting (AKA “morning sickness” );
constipation;
heartburn (pyrosis), esophageal reflux;
intrahepatic cholestasis of pregnancy due to ↓ gallbladder emptying time → ↑ risk of cholelithiasis

65
Q

(SmartyPance)

physiology of pregnancy: urinary & renal changes

A

physical space problems b/w bladder and uterus = urinary frequency, nocturia, stress incontinence

increase GFR, increase size of kidneys

physiologic hydronephrosis

glycosuria, increase protein excretion (urine)

66
Q

(SmartyPance)

shift in center of gravity
diastasis recti = separation of abdominal rectus m.m.
increase joint mobility (waddling)

68
Q

(SmartyPance)

physiology of pregnancy: endocrine changes

A

↑ size of pituitary gland

↓ thyroid-stimulating hormone (TSH); thyroid gland enlarges; ↑ total T3, T4

↑ parathyroid hormone (meets calcium need of developing fetal skeleton)

Physiologic hypercortisolism

“Diabetogenic state” of pregnancy

Reproductive hormones
hCG from placenta; estrogen, progesterone from corpus luteum
Suppressed FSH, LH due to feedback from estrogen, progesterone, inhibin
↓ oxytocin levels throughout pregnancy → ↑ labor onset → ↑↑ second stage of labor
