- Epidural
- Full dilataion 1 hour, passive 2nd stae
- Pushin 90 minutes
- No signs of birth
- she is well, contractions strong 4/10 minutes
- FHR normal
- Most appropriate step
A- commence IV oxytocin
B- Operative vaginal delivery after 30 minutes if no change
C- Operative vaginal delivery after 60 minutes if no change
D- discuss operative vainal delivery immediately
E- encourage direct pushing in lithotomy
B
She is a G2
Time allowed -3 hours
Including passive stage, time elapsed is 2 and a half hours
So remaining time is 30 min.
For Primi it would be four hours so 60 min option would be right

- 42 y/o
- lost 2 litres blood, Em CS for fetal distress(DCDA) twins.
When considering the administration of blood and blood products which is correct?
A. FFPs contain more fibrinogen than cryoprecipitate
B. FFP is derived from whole blood and doesn’t contain clotting factors
C. FFP is stored at -30”c and needs to be defrosted thoroughly prior to administration
D. A PT & APTT ratio: below 1.5 associated with increased risk of a clinical coagulopathy
E. A unit of concentrated red cells increases hematocrit by 8%
Key is C
- PT/APTT ratio above 1.5 is ass with inc risk of coagulopathy.
- Cryoprecipitate contain more fibrinogen than ffp and is used to correct hypo fibrinogenemia
- FFP is derived from whole blood and contains Clotting factors.
- PRBCs raises Hb by 1 g/dl and Hct by 3%
What is the incidence of shoulder dystocia in vaginal deliveries? A) 0.1% B) 0.6% C) 1.5% D) 2.5% E) 3.5%
Key -B

- bowel resection for Crohn’S disease
- now pregnant
- Advice: vitamin D & calcium
Main mech of actio of Vit D on calcium metabolism.
A- stimulates parathyroid gland & promotes bone formation
B- decreases renal excretion of calcium from tubules
C- Increases calcium absorption from small intestine
D- Increases calcium absorption from large intestine
E- stimulates osteoclast formation
C- Increases calciumC- Increases calcium absorption from small intestine absorption from small intestine
- Asthmatic
- pregnant
- received short acting betal blocker & 800 steroid
- but asthma not controlled
NEXT STEP A- steroid B- LABA C- theophyline D- leukotriene E- refer to specialist
B- LABA
Perimortem CS time A- 3 min B- 4 min C- 6 min D 10 min
B- 4 min
where to implement decision of OVD is taken
- if implemented in labour room it took 15 min and if implemented in OT it took 30 min .
- If delivery in labour room fails shifted for Cs more time wasted as compare to shift to OT and try and if failed immediately CS.
- though it’s less time in LR delivery, studies found no significant differences in outcome of delivering in LR/OT.
And the risk of injury during shifting can be outweigh by a failed attempt in LR ‘
