Answer
  • Partogram

Question 11

Question
Syntocinon is the synthetic form of the hormone [blank_start]oxytocin[blank_end] that is used to induce uterine contractions in labour
Answer
  • oxytocin

Question 12

Question
The chart on which the foetal heart rate is monitored alongside maternal uterine contractions is known as the [blank_start]cardiotocogram[blank_end] (don't use abbreviation)
Answer
  • cardiotocogram

Question 13

Question
Cardiotocograms (CTGs) are analysed using the acronym DR C BRAVADO. What do the letters stand for? DR - [blank_start]Define Risk[blank_end] C - [blank_start]Contractions[blank_end] BRA - [blank_start]Baseline Rate[blank_end] V - [blank_start]Variability[blank_end] A - [blank_start]Accelerations[blank_end] D - [blank_start]Decelerations[blank_end] O - [blank_start]Overall[blank_end] Judgement
Answer
  • Define Risk
  • Contractions
  • Baseline Rate
  • Variability
  • Accelerations
  • Decelerations
  • Overall

Question 14

Question
In terms of analysing the CTG, the Baseline Rate refers to the foetal heart rate. What is the normal foetal heart rate? Between [blank_start]100-160[blank_end] BPM
Answer
  • 100-160
  • 100-140
  • 120-140
  • 120-160

Question 15

Question
In terms of analysing the CTG, the variability refers to the change in the foetal heart rate from one beat to the next. In a healthy foetus, the variability is between [blank_start]5-25[blank_end] BPM
Answer
  • 5-25
  • 5-10
  • 10-20
  • 15-25

Question 16

Question

Answer
  • 15
  • 5
  • 10
  • 15
  • 5
  • 10

Question 17

Question

Answer
  • normal
  • abnormal
  • a healthy
  • an unhealthy

Question 18

Question
In terms of analysing the CTG, decelerations are abrupt decreases in the foetal heart rate of >[blank_start]15[blank_end]BPM for >[blank_start]15[blank_end] seconds
Answer
  • 15
  • 5
  • 10
  • 15
  • 5
  • 10

Question 19

Question
Decelerations can be early, late or variable: [blank_start]Early decelerations[blank_end]: Occur exactly in time with uterine contractions and recover by the time the contraction is over [blank_start]Variable decelerations[blank_end]: Have a variable recovery time [blank_start]Late decelerations[blank_end]: Occur at the peak of a contraction and don’t recover until after the contraction is over
Answer
  • Early decelerations
  • Variable decelerations
  • Late decelerations

Question 20

Question
Which type of decelerations are usually caused by cord compression?
Answer
  • Early Decelerations
  • Variable Decelerations
  • Late Decelerations

Question 21

Question
Which type of deceleration is considered normal and expected on a CTG?
Answer
  • Early Deceleration
  • Variable Deceleration
  • Late Deceleration

Question 22

Question
Which type of decelerations are almost always a sign of foetal distress and should be thoroughly investigated?
Answer
  • Early Decelerations
  • Variable Decelerations
  • Late Decelerations

Question 23

Question
Which 2 sites can you take blood from to determine if a foetus is hypoxic?
Answer
  • Capillaries in the foetal scalp (via vaginal examination)
  • Umbilical cord upon delivery
  • Amniotic fluid
  • Maternal blood

Question 24

Question
If the foetal blood pH is [blank_start]under 7.2[blank_end] the baby is likely to be hypoxic and should be delivered
Answer
  • under 7.2
  • under 7.3
  • over 7.4
  • over 7.5

Question 25

Question
Assisted Vaginal Delivery typically involves these two tools. What are they called?
Answer
  • Forceps
  • Ventouse

Question 26

Question
In the case of failure to progress in labour (without epidural anaesthesia), how long would you try for a spontaneous vaginal delivery before attempting assisted vaginal delivery? Primigravida = [blank_start]2 hours[blank_end] Multiparous = [blank_start]1 hour[blank_end]
Answer
  • 2 hours
  • 1 hour
  • 1 hour
  • 2 hours

Question 27

Question
Ventouse delivery is typically more effective that a forceps delivery
Answer
  • True
  • False

Answer
  • Placenta accreta

Question 29

Question
Which of the following warrants immediate foetal blood sampling?
