A

Transmission of GBS to the neonate from mothers who are colonized usually occurs:
- just before birth – PROM

Q

placental abruption vs placenta previa

Placenta is implanted in the lower uterine segment such that it completely or partially covers the cervix or is close enough to the cervix to cause bleeding when the cervix dilates or the lower uterine segment effaces.

A

placenta previa = placenta over cervix

21
Q

________ is

Term used to indicate that the largest transverse diameter of the presenting part (usually the biparietal diameter) has passed through the maternal pelvic brim or inlet into the true pelvis and corresponds to station 0.

A

engagement

22
Q

__________ is

Relationship of the presenting fetal part to an imaginary line drawn between the ischial spines of the pelvis. It is a measure of the degree of descent of the presenting part of the fetus through the birth canal.

A

station

23
Q

Normal baseline range of FHR

A

110 to 160 beats/min

24
Q

irregular waves or fluctuations in the baseline FHR of two cycles per minute or greater

A

Variability

25
Q

which type of variability - Moderate, minimal, absent, marked

amplitude range of the FHR fluctuations that is not detectable to the unaided eye.

an amplitude range that is detectable to the unaided eye but is 5 beats/min or less

is considered normal, amplitude range 6 - 25 beats/min

amplitude range 25 or more beats/min

A

Absent variability -
Minimal variability -
Moderate variability -
Marked amplitude -

26
Q

Fetal tachycardia

baseline FHR greater than ___ beats/min for __ minutes or longer

A

Fetal tachycardia

baseline FHR greater than 160 beats/min for 10 minutes or longer

27
Q

Fetal bradycardia

baseline FHR less than ___ beats/min for __ minutes or longer

A

FHR <110 beats/min lasting >10 min

28
Q

nursing care for ______________:

  • Discontinue oxytocin if infusing.
  • Assist woman to lateral (side-lying) position.
  • Correct maternal hypotension by elevating legs.
  • Increase rate of maintenance IV solution.
  • Palpate uterus to assess for tachysystole.
  • Notify obstetric health care provider
  • Consider internal monitoring for more accurate fetal and uterine assessment.
  • Assist with birth (vaginal-assisted or cesarean) if pattern cannot be corrected.
A

bradycardia

29
Q

visually apparent, abrupt (onset to peak <30 seconds) increase in FHR above the baseline rate

After 32 weeks, The peak is at least 15 beats/min above the baseline, and the acceleration lasts 15 seconds or more, with the return to baseline less than 2 minutes from the beginning of the acceleration.

Before 32 weeks of gestation, the definition of acceleration is a peak of 10 beats/min or more above the baseline and a duration of at least 10 seconds.

A

accelerations

30
Q

visually apparent, gradual (onset to lowest point ≥30 seconds) decrease in and return to baseline FHR associated with UCs.

A

Early decelerations

31
Q

visually abrupt (onset to lowest point <30 seconds) decrease in FHR below the baseline.

The decrease is at least 15 beats/min or more below the baseline, lasts at least 15 seconds, and returns to baseline in less than 2 minutes from the time of onset

A

variable decelerations

32
Q

visually apparent, gradual (onset to lowest point >30 seconds) decrease in and return to baseline FHR associated with UCs. The deceleration begins after the contraction has started, and the lowest point of the deceleration occurs after the peak of the contraction.

A

Late decelerations

33
Q

categories of FHR tracings

FHR tracings are normal and strongly predictive of normal fetal acid-base status at the time of observation. These tracings may be followed routinely and do not require any specific action.

FHR tracings are indeterminate.

FHR tracings are abnormal. Immediate evaluation and prompt intervention are required when these patterns are identified

A

Category I

Category II

Category III

34
Q

The return of the uterus to a nonpregnant state after birth is called

This process begins immediately after expulsion of the placenta with contraction of the uterine smooth muscle.

A

involution.

35
Q

? is the failure of the uterus to return to a nonpregnant state as a result of ineffective uterine contractions.

The most common causes

A

Subinvolution

retained placental fragments and infection

36
Q

A major intervention to alleviate uterine atony (boggy uterus) and restore uterine ­muscle tone is stimulation by

A

gently massaging the fundus until firm

intravenous fluids and oxytocic medications (drugs that stimulate contraction of the uterine smooth muscle)

37
Q

How does a distended bladder increase vaginal bleeding after delivery?

A

A full bladder causes the uterus to be displaced above the umbilicus and well to one side of midline in the abdomen. It also prevents the uterus from contracting normally.

38
Q

Cord clamp in place for ________ hours

A

24–48

39
Q

hypothermia creates a vicious cycle in a newborn. As the baby gets colder, they need more _____, but their body struggles to take __________, leading to ____________

A

hypothermia creates a vicious cycle in a newborn. As the baby gets colder, they need more oxygen, but their body struggles to take in and utilize oxygen effectively, leading to respiratory distress.

40
Q

Should a baby that does not receive Vitamin K have a circumcision in the first few days of life? Why or why not?

A

Male infants who do not receive the vitamin K injection are significantly more likely to bleed after circumcision
