* Calcium gluconate/calcium chloride readily available to
reverse mag toxicity
What does terbutaline do?
inhibit uterine activity and stops preterm labor
Contraindications for terbutaline?

- Hyperthyroidism
Contraindications
How to tell if terbutaline is working?
number and frequency of contractions decrease or stops altogether
What to assess for before/during pitocin?
-fetal presentation and descent
-FHR
-contraction pattern and intensity every 15 mins
Guidelines for pitocin?
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.
What is HELLP syndrome?
HELLP syndrome is a variant of preeclampsia that involves hepatic dysfunction, characterized by:
· H Hemolysis (Breakdown in RBC)
· EL Elevated Liver enzymes (liver isn’t getting rid of all the toxins)
· LP Low platelet count (normal platelet: (platelets arent coagulating enough)
How will a patient present with HELLP syndrome?
Can range from NO symptoms to N/V, epigastric pain, malaise, RUQ pain
What are nursing considerations for HELLP syndrome?
· 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.
How is HELLP syndrome diagnosed?
lab work

-You will see decreased serum albumin, increased Hct and BUN, creatinine and uric acid -concentration at or above 30mg/dL (>/=- 1+ on dipstick)
What are warning signs for HTN?
Onset of HTN WITHOUT protein in the urine and mother is past 20 weeks gestation. Mom is just pregnant with HTN. -recorder at least 2 separate occasions at least 4-6 hrs apart w/in 1 week and no sign of UTI -BP returns to normal w/in 1-12 weeks postpartum
140/90

What are the cardinal mechanisms of labor?
· Engagement – BPD at pelvic inlet
· Descent – measured by station + numbers lower than ischial spines

Extension – occiput passes under symphysis pubis and head … first the occiput
· External rotation (restitution) – realignment of infant head to back/shoulders (back to original position)
· Expulsion (birth) – anterior shoulder under symphysis pubis à posterior shoulder and body completely emerges
