multi babies (mulipara)
1st Stage of Labor:
Latent- 0-3cm dilated, 5-30 min between contractions, mom is talkative and anxious
Active- 4-7cm dilated, 2-5 minutes between contractions, mom is focused on self
Trasition- 8-10cm dilated, 2-3 minutes between contraction

Nursing interventions for oxytocin/pitocin:
monitor contractions (if >90 seconds in duration or more frequent than 2 minutes discontinue) , monitor FHR, check dilation, vital signs, DECELS, no obstructions, water intoxication so monitor I&O, monitor pain

Epidural can cause what side effect
maternal hypotension. Give LR to increase fluids which can prevent hypotension
Epidurals do not cross what? the dura mater
Side effect of spinal anesthetic?
Headaches due to a leakage of cerebral spinal fluid. Need to take patients blood and block this leakage. Place patient lying down supine to decrease headaches. Caffeine may also help
How often should you assess BP after giving epidural
every 5 minutes for 20 minutes–> longer if the BP is decreased
Fentanyl is used for..
short term pain relief which is good for rapid laboring patients
Morphine is good for..
long term pain relief. It has risks to both the mom and the fetus. it can cause itching so you nay need to give benadryl or nubain. Assess respiratory status every hour

Hcg has been linked to nausesa
vitamin B6 can decrease sickness
ptyalism
excessive salivation is common- avoid spicy foods
pyrosis
heartburn increases due to progesterone production which causes the tone and mobility of smooth muscles to become decreased (leads to regurgitation and decrease gastric emptying)

rapid drop- progesterone, estrogen
increase in- prolactin and oxytocin
let down reflex
flow of milk results from oxytocin which increases contractility

Gynecoid and antrhopoid
Android and platylepelloid are
pelvis that are not favorable and can result in transverse positioning
client at 39 weeks’ gestation calls the clinic nurse with complaints of pelvic pressure, urinary frequency, and vaginal secretions. The nurse would correctly interpret these as signs and symptoms of:
impending labor
A nurse is caring for a client admitted to the birthing unit with rupture of membranes that occurred two hours ago. A pelvic exam reveals a dilatation of 4 cm, and the presenting part is not engaged. The patient asks if she can walk in the hallway. The nurse’s response that bed rest is required is based on the risk of:
prolapsed cord–When a pelvic exam reveals a dilatation of 4 cm and the presenting part is not engaged, the nurse should anticipate a prolapsed cord.
