Tachycardia 

100

First action for heavy bleeding? 

Call for help and massage the fundus

100

First line uterotonic?

Oxytocin

100

Definition of PPH after vaginal birth?

200

What is an example of tone cause

Uterine atony, boggy, full bladder

200

What to do if the uterus feels boggy? 

Massage the fundus

200

Positions to improve perfusion

Flat or Trendelenburg

200

What medication is contraindicated in hypertension 

Ergot

200

Definition of PPH after c-section?

Blood loss >1000mL

300

Example of Tissue cause?

Retained placenta or membranes

300

Why does prolonged oxytocin infusion predispose to PPH

Receptor desensitization-->becomes less responsive to oxytocin. 

300

why is BP often normal until later PPH

Pregnant patients have increased blood volume so they are able to compensate for longer before hypotension occurs 

300

What medication is contraindicated in asthma

Hemabate

NS, sterile saline NOT air

500

Surgical option for uncontrolled PPH?

Hysterectomy 

500

How does magnesium sulfate increase risk for PPH

Acts as a Smooth muscle relaxant reducing uterine tone

500

Gold standard for assessing blood loss?
