sleep cycle
38
persistant variability over 60 mins despite intervention indicates X3
hypoxia, hypoxemia, acidosis
39
maternal causes of FHR variability X4
narcotics, CNS depressants, mag sulfate, anesthesia
40
what protects umbilical cord vessel
wharton's jelly
41
what are the 5 factors for adequate fetal oxygenation
maternal: normal maternal O2, adequate exchange of O2 and CO2, sufficient blood flow fetal: placental circulation via cord, normal circulatory and O2 carrying function
42
what do the umbilical arteries transport
return deoxygenated blood back to the mom
43
periodic FHR changes are
FHR changes r/t a uterine contraction
44
episodic FHR changes are
unrelated to a uterine contraction
45
what is a FHR acceleration
increase of FHR of 15 bpm above baseline for 15+ seconds preemie: 10 bpm in 10 seconds
46
when can accelerations occur
contractions, vaginal exams or breech presentions
47
what does an acceleration show
reassuring - shows a non-acidotic, reactive and healthy fetus
48
nursing interventions for accelerations
no nursing interventions required
49
what is an early decel
gradual decrease of FHR below baseline as contraction begins and returns to baseline as contraction ends
50
what can an early decel indicate
baby descending down pelvis
51
nursing interventions for early decels
no interventions needed - consider vag exam to check labor progress
52
late decelerations are
a gradual decrease in FHR below basline that begins after contraction
53
what does a late decel reflect
ominous, non-reassuring pattern showing placental insufficiency
54
nursing interventions for late decelerations
IUR done immediately
55
maternal causes of late decels X6
hypotension, placental previa or abruption, HTN, diabetes, placental changes, uterine hyperstimulation or tachysystole
56
tachysystole
too many contractions at one time
57
Variable decelerations
abrupt decrease in FHR that is vairable in shape and duration
58
cause of variable decelerations
restricted blood flow in the cord
59
nursing interventions for variable decels
IUR done immediately
60
prolonged deceleratinos
decrase in FHR below baseline lasting 2-10 minutes
61
what does a prolonged deceleration under 2 minutes indicate
baseline change
62
what causes prolonged decels
interruption of uteroplacental perfusion/umbilical blood flow
63
nursing interventions for prolonged decelerations
IUR done immediately
64
VEAL CHOP variable
variable - cord compression - move patient
65
VEAL CHOP early
early - head compression - initiate c-section measures
66
VEAL CHOP acceleration
acceleration - OK - nothing
67
VEAL CHOP late
late - placental insufficiency - emergency delivery
68
duration
length of contraction from beginning to end
69
frequency
beginning of one contraction to beginning of the next
70
relaxation time
end of one contraction to the beginning of the next
71
what is adequate relaxation time
>60 seconds to allow for uterine flow
72
IUPC normal resting tone
5-15
73
IUPC hypertonus resting tone
20-25
74
mild intensity or 1+ feels like
your nose
75
moderate intensity or 2+ feels like
chin
76
strong intensity or 3+ feels like
forehead
77
IUPC mild contraction pressure
30 mmHg
78
IUPC strong contraction pressure
70 mmHg
79
labor average IUPC pressure
50-75 mmHg up to 110 when pushing
80
normal contraction rate
5 or fewer contractions in a 10 minute window averaged over 30 minutes
81
how long should normal contractions last
45-90
82
tachysystole
5+ contractions in a 10 minute period averaged over 30 minutes
83
what is hypertonic uterine activity
resting tone between contraction is high reducing uterine blood flow and decreasing fetal O@ supply
84
what does hypertonic uterine activity contribute to X4
hypoxemia, hypoxia, metabolic acidosis, metabolic acidemia
85
tocolytic drug
terbutaline
86
maternal position to reduce uterine activity and why
left lateral - improves blood flow
87
how many tiers are in the FHR interpretation system
3
88
category I FHR is
normal
89
what qualifies a category I FHR
moderate variability, baseline of 110-160. potentially accelerations and early decels
90
what must be absent in a category I FHR
late and varied decels
91
nursing interventions for Category I FHR
no action required
92
category II FHR is
indeterminate - fetal acid/base status is uncertain
93
what qualifies a category II FHR
tracings not categorized as I or III
94
nursing interventions for category II FHR
requires continued intervention, evaluation and reevaluation
95
category III FHR is
abnormal and shows a problem in the fetal acid/base balance
96
what qualifies a category III FHR
absent variability, and/or recurring late decels, recurring varied decels, bradycardia, sinusoidal pattern
97
nursing interventions for a category III FHR
initiate IUR and prompt provider evaluation and delivery
98
what does IUR consist of
"The 4 turns" Turn patient - left lateral Turn IV fluid up - 500 mL NS/LR Turn O2 on - 10 L/min via non-rebreather Turn oxytocin off notify MD ASAP
99
during IUR, consider X3
correcting maternal hypotension, performing amnioinfusion, modifying second stage pushing efforts
100
when should you do an amnioinfusion
variable deceleration
101
what does modifying second stage pushing efforts mean
push every 2nd or 3rd contraction to allow for refill
102
preemie monitoring considerations
higher baseline w/n normal range, accels may have lower amplitude and variability may be decreased
