Q

what is a mechanically induction

A

cervical ripening
uses a foley bulb which puts pressure on the cervix just like the fetal head would causing prostaglandins to be released to soften the cervix

Q

what should be occurring when an amnioinfusion is happening

A

water should be leaking back out
if no fluid noted and you have increased uterine resting tone, stop transfusion immediately

Q

what intervention is done to encourage water to come out after amnioinfusion is turned off because of no fluid return

surgical incision of the perineum to enlarge the vaginal outlet -> two types are midline or mediolateral and can be classified from 1st degree to 4th degree

fetal head engaged @ 0 station
used rarely bc higher reach

28
Q

low forceps

A

fetal head +2 station

29
Q

fetal head at perineum

30
Q

maternal risks to forceps use

A

-perineal edeam

31
Q

A

-caput succedaneum or cephalhematoma
-transient facial paralysis, brachial plexus
-cerebral hemorrhage
-fractures (clavicle)
-elevated neonatal bilirubin levels

32
Q

nursing mgt for forceps assisted births

A

-explain procedure to women
-monitor contractions
-inform physician/CNM of contraction
-encourage women to push during contraction
-reassurance
-document length of the forceps used (when applied & removed)

33
Q

Vacuum Extraction

A

-suction cup placed on fetal occiput
-pump is used to create suction
-traction is applied
-fetal head should descend w/ each contraction
-document length of time vacuum is used (put on, when pressure was applied, when pressure was turned off and when the vacuum was off)

34
Q

Cesarean Birth Indications

A

-complete placenta previa
-CPD
-Placental abruption
-active genital herpes
-umbilical cord prolapse
-failure to progress in labor
-tumors that obstruct the birth canal
-breech presentation
-previous C section
-major congenital anomalies
-non reassuring fetal status

35
Q

what is the usual uterine incision

A

low transverse

36
Q

what does a classical uterine incision or low vertical incision put mother at high risk for

A

a uterine rupture if vaginal delivery to tried
best practice is to have another c sections future children & placenta previa bc placenta will want to attached to scarring

37
Q

nursing mgt before C section

A

-assist w/ epidural or spinal
-unscheduled sections will get get pepcid & reglan to neutralize stomach acid as well as bicitra 30 mins before
- monitor maternal VS
-obtain fetal HR
-insert foley
-prepare abdomen and perineum
-make sure all necessary personnel and equipment are present

38
Q

nursing mgt during C section

A

-position the women on the operating table (wedge for left tilt prior to delivery)
-support the couple
-instrument count (before, during, after)
-time out (final checks for consent & safety)
-document

39
Q

what do you document during a C section

A

incision, delivery of infant, APGARS, AROM if done, placenta extracted, EBL, & meds received

40
Q

nursing mgt after c section

A

-normal newborn post delivery care
-monitor VS every 15 mins
-check the surgical dressing
-palpate the fundus and checking lochia
-monitor intake & output
-administrate IV Oxytocin

41
Q

visceral pain

A

slow deep pain that is dull or aching
very common in first stage of labor

42
Q

somatic pain

A

sharp and localized and is like a burning or tearing feeling
common during the transition or pushing phase of labor

43
Q

do pain meds cross through the placenta during labor

A

yes

44
Q

when are you going to give systemic analgesia

A

since fetal liver and kidney excretion is inadequate for metabolizing med you will do it when women is uncomfortable, in a well established labor pattern, contractions are occurring regularly, there is a significant during of contractions and contractions are moderate to strong in intensity

45
Q

contraindications for systemic analgesia

A

allergies
hypotension
non reassuring fetal strip
don’t give systemic right before delivery bc could affect respiratory off baby

46
Q

what medication can you not give to mothers with substance abuse issues

A

nalbuphine hydrochloride -> can initiate w/draw & cause neonatal abstinence syndrome

47
Q

major consideration for meperidine

A

naloxone (Narcan) does not reserve affects on the infant

48
Q

regional anestesia

A

temporary and reversible loss of sensation & prevents initiation and transmission of nerve impulse for pain control

49
Q

epidural disadvantages

A

-maternal hypotension (give LR bolus)
-post delivery back pain
-meningitis
-cardio respiratory arrest
-vertigo
-onset of analgesia may not occur for up to 30 mins

50
Q

advantages to a spinal

A

-immediate onset of anesthesia
-relative ease of administration
-smaller drug volume

51
Q

disadvantages of a spinal

A

-high incidence of hypotension
-greater potential for fetal hypoxia
-short acting

52
Q

advantages to a combined spinal epidural

A

-spinal has a faster onset
-meds can be added
-low doses

53
Q

disadvantages to a combined spinal epidural

A

-higher incidence of nausea
-pruritus

54
Q

nursing mgt prior to epidural/spinal placement

A
