R C/S

Answer 4

• Repeat c-section
• Woman who had one or more previous c-sections

Question 5

AROM

Answer 5

• Artifical rupture of membranes
• Amniotomy
  
  • Intentional rupture of the amniotic sac with a sterile amniohook, allis forceps, or amniotome to stimulate or augment labor

Question 6

SROM

Answer 6

• Spontaneous rupture of membranes
• Contractions towards the end of labor cause membranes to rupture (water breaks)

Question 7

ROM

Answer 7

• Rupture of membrane
• The rupture of the amniotic sac as a normal result of dilation of the cervix uteri in labor

Question 8

GDM

Answer 8

• Gestational DM
• Maternal hyperglycemia
  
  • Insulin resistance that begins or is 1st dx during pregnancy

Question 9

GA

Answer 9

• Gestational Age
• The age of an embryo or fetus as timed from the date of onset of the last menstrual period

Question 10

EDD

EDB

EDC

Answer 10

• Estimated Date of: Delivery, Birth, Confinement
• Uterus enlarges in a predictable pattern that provides information on fetal growth and helps confirm EDD

Question 11

FHR (FHT)

Answer 11

• Fetal Heart Tone
  
  • Cardiotocograph is used to monitor fetal heartbeat and uterine contractions typically during 3rd trimester
• Fetal Heart Rate
  
  • Between 120-160 BPM

Question 12

FSE

Answer 12

• Fetal Scalp Electrodes
• Internal monitor that detects electrical signals from the HR
  
  • Continual electrical monitoring
  • Used during high-risk pregnancies

Question 13

FHRP

Answer 13

• Fetal HR pattern
• Determination of baseline FHR variability is based on visual assessment and excludes sinusoidal patterns
  
  • Accelerations, late and early decelerations, variable decelerations and prolonged decelerations

Question 14

NST

Answer 14

• Non-stress test
• Measure HR of fetus in response to its own movements
  
  • No stress used during test
  • FHR should increase with movement

Question 15

IUGR/FGR

Answer 15

• Intrauterine growth retardation (restriction)
• Fetal growth restriction (retardation)
• A decreased rate of fetal growth, most commonly related to inadequate placental perfusion
  
  • Infants birth weight is below the 10th percentile on intrauterine growth curve for the calculated gestational period

Question 16

IUFD

Answer 16

• Intrauterine fetal death
• Death of fetus while in utero

Question 17

PIH

Answer 17

• Pregnancy Induced Hypertension
• High BP in pregnancy (preeclampsia or eclampsia)
  
  • Occurs after 20 weeks of pregnancy

Question 18

Answer 18

• Phenlyketonuria
• Congenital disease marked by failure to metabolize phenylalanine to tyrosine
  
  • Results in severe neurological deficits in infancy

Question 19

SVE

Answer 19

• Sterile Vaginal Exam
• Exam of vagina, cerfix, adnexa, and fetus during labor
  
  • Determines progress of labor

Question 20

LMP/LNMP

Answer 20

• Last menstrual period, last normal menstrual period
• Helps determine GA (gestational age)

Question 21

IUPC

Answer 21

• Intrauterine Pressure Catheter
• Internal monitor inserted into the uterus between the baby and uterine wall that provides precise measurements of contractions

Question 22

EBL

Answer 22

• Estimated Blood Loss
• Estimated amount of blood loss during delivery

Question 23

NSVD

Answer 23

• Normal Spontaneous Vaginal Delivery
• NSVD occurs when a pregnant female goes into labor without the use of drugs or techniques to induce labor
• Delivers baby in the normal manner without forceps, vacuum extraction, or c-section

Question 24

VBAC

Answer 24

• Vaginal Birth After C-Section
• Women who had a previous c-section delivered their next baby vaginally

Question 25

VAVD

Answer 25

• Vacuum Assisted Vaginal Delivery
• Vacuum with soft plastic cup inserted into birth canal and attached to the baby’s head
• The MD then uses the vacuum handle to guide the baby through the birth canal

Question 26

FH

Answer 26

• Fundal Height
• Used to evaluate fetal growth while confirming gestational age

Question 27

EFM

Answer 27

• Electronic Fetal Monitoring
• Either internal or external monitor used to note any unusual changes in FHR and uterine changes
  
  • Used late in pregnancy

Question 28

UC

Answer 28

• Uterine Contractions
• Periodic, rhythmic, tightening of the uterine muscles

Question 29

PTL

Answer 29
