False.

Antenatal risk factors for PPH?

( List Four).

Over distension of Uterus eg Twins, polyhydramnios Anaemia, Therapeutic anticoagulation                    Hx previous PPH, Gradmulti,.Fetal Macrosomia    BMI above 35.  Uterine anomalies. Maternal bleeding Disorders.

Why is it important to facilitate left lateral displacement of the uterus during CPR?

Reduces uterine compression of aorta and vena cava.This can increase cardiac output to support mother and baby.

400

When filling a bladder to relieve cord pressure, how much fluid should be used?

500mls.

This should distend the bladder above the pubis.

500

In order, list first line uterotonics and doseages in PPH management

2nd dose Oxytocin - 5iu IV or 10iu IM

Ergometrine - 250mcg IV or IM

OR

Syntometrine - IM (oxytocin 5iu & ergometrine 500mcg)

CTG

100

What are the four features that should be considered when interpreting a CTG?

Baseline

Variability

200

What could be the causes of prolonged fetal bradycardia?

( list three).

• Prolonged cord compression
• Cord prolapse
• Epidural and spinal anesthesia
• Maternal seizures
• Rapid fetal descent

300

What actions should you take if the CTG has had two yellow zones?

Two yellow ctg make a red zone.

 Tier two escalation, commence maternity resus measures eg change position etc.

What causes a sinusoidal fetal heart rate pattern?

List 2

hypoxia, CNS injury, infection, cardiac anomalies, anaemia,  drugs

500

Fetal tachycardia is defined as a baseline heart rate greater than 160 bpm.

3 causes of fetal tachycardia are

• Fetal hypoxia
• Chorioamnionitis
• Hyperthyroidism
• Fetal or maternal anaemia
• Fetal tachyarrhythmia
