Q

Guidelines for pitocin?

A

The goal is to achieve a pattern of 3 contractions every 10 minutes that last around 40-60 seconds. The cervix should be dilating at a rate of 1 cm per hour, and the dose should be reduced once the cervix has dilated to 5-7cm. Pitocin is usually stopped once dilation reaches 7-8cm.

Q

What are nursing considerations for HELLP syndrome?

A

· Assess for signs of bleeding especially petechiae or bruising from BP cuff, these are signs she isn’t clotting well.
· Check IV sites and gums, if she’s bleeding, there is a problem.
· Tenderness in RUQ or if she tells you it feels like she has indigestion, this means liver involvement.
· Pt could start to look jaundice or yellow=monitor labs and if abnormal, CALL HCP!
· If mom is preggo and we see these signs, this is a precursor for mom to have a placenta that abrupts, which will kill the baby.
