Question 7

placental abruption vs placenta previa

Premature separation of the placenta; the detachment of part or all of a normally implanted placenta from the uterus before the birth of the infant.

Answer 7

placental abruption = placenta detachment

Question 8

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.

prolonged labor

Question 21

________ 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.

Answer 21

engagement

Question 22

__________ 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.

Answer 22

station

Question 23

Normal baseline range of FHR

Answer 23

110 to 160 beats/min

Question 24

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

Answer 24

Variability

Question 25

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

Answer 25

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

Question 26

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

Answer 26

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

Question 27

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

Answer 27

FHR <110 beats/min lasting >10 min

Question 28

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.

Answer 28

bradycardia

Question 29

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.

Answer 30

Early decelerations

Question 31

Late decelerations

Answer 39

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.
