Introduction Part 1 maternity & mental health Flashcards
electronic fetal monitoring identifies what
non reassuring fetal heart rate tracings
what is the amplitude of external contraction monitoring effected by?
belt tightness, amount of adipose tissue, amount of amniotic fluid, position of mom and fetus and contraction strength
internal monitoring can be used only if…
after the rupture of membrane and cervical dilation
internal contraction monitoring accurately measures what
frequency, duration, intensity, resting tone, fetus’s favorite color
what is the normal fetal heart rate baseline
110-160 bpm
the frequency of a contraction is measured on the strip from what to what
beginning of one contraction to the beginning of the next contraction
the resting phase of a contraction pattern is wen the fetus gets what
re-oxygenated
when can you start listening to the fetal heart rate
8-12 weeks
abnormal findings in heart rate mean what
a compromised fetal state
what are reasons that a fetal heart rate can not be auscultated
too early in pregnancy fetal death maternal obesity polyhydramnios fetal position peak of contraction
polyhydramnios
too much amniotic fluid
why was fetal monitoring first done
so cerebral palsy can be detected
doppler
ultrasound device, detects heart rate, used for low risk labor
electronic fetal monitoring
ongoing assessment of fetal oxygenation, looking for changes, device is placed over the fetal back and transmits to the monitor
the electronic fetal monitoring measures what
rate and pattern of fetal heart tones
uterine monitoring
placed on maternal fundus (top portion of uterus, gets tightest during contractions), measures in mmHg
uterine monitoring measures what
frequency, duration, intensity and resting tone
where is the fetal internal monitoring placed
electrode is clipped to baby’s skin (scalp)
does external monitoring show intensity of a contraction?
no, intensity is done by palpation
why is internal monitoring used
more accurately detects fetal heart rate and changes in FHR, and is not impeded by obesity, position or fluid
internal uterine monitoring is done because
shows pressure changes in uterus, more exact (objective) measurement of uterine activity (frequency, duration, resting tone and intensity)
what are the components of the internal/external monitoring paper
upper portion = fetal heart rate
lower portion = uterine activity
small block 10 seconds
large block 1 minute
average fetal HR observed during a 10 minute window, increases and decreases will not be counted
baseline
interplay between the sympathetic and parasympathetic nervous systems
baseline variability
absent baseline variability
amplitude is undetectable
minimal baseline variability
1-5 bpm (peak to trough)
moderate baseline variability
6-25 bpm (peak to trough)
marked baseline variability
more than 25 bpm (peak to trough)
where do we want the baseline variability to be?
moderate
what is the most sensitive indicator of fetal well being, and most important aspect of the strip
baseline variability
baseline of less than 110 bpm
bradycardia
what can unresolved bradycardia lead to
hypoxia
*intervention is needed
baseline of greater than 160 bpm
tachycardia
baseline of greater than 180 bpm
severe tachycardia
visual abrupt, temporary increase in FHR above baseline
accelerations
increase of 15 bpm, that 15 seconds of baseline from beginning to end
are accelerations normal? why or why not
yes, indicate fetal well being and an intact nervous system (seen with fetal movement)
decrease of FHR baseline, occurs with blood supply change to fetus
decelerations
Early Deceleration
gradual decrease of FHR below baseline, ALWAYS occurs with the contraction
*mirrors contraction
cause of early deceleration
fetal head compression
fetal head compression causes what
increase of ICP = decrease cerebral blood flow = vagal nerve stimulation = decrease of FHR
variable deceleration
abrupt decrease of FHR & abrupt recovery
Shape of V, W, U
are variable decelerations common
yes
what is the cause of a variable deceleration
cord compression
late deceleration
gradual decrease in FHR, occurs after contraction and with every contraction
**NOT GOOD
when does an early deceleration happen
mirrors contractions
when does a variable deceleration happen
varies
when does a late deceleration happen
after every contraction and with every contraction
cause of late deceleration
utero-placental insufficiency
*decrease in available O2 to fetus
fetal heart rate patterns that are abnormal may indicate what
fetal distress
what are S & Sx of fetal distress
bradycardia, tachycardia, decrease baseline variability (decrease of fetal movement), periodic changes
POPI
POSITION-relieve cord compression & fetal weight on moms vena cava (Left lateral position)
OXYGEN-non re-breather 10 lpm
Stop PITOCIN-stop Rx, which will stop contractions
IV Bolus- increase blood flow to fetus, increase intravascular volume
what can be done if there is fetal distress
POPI, internal monitor, call MD, administer tocolytic
Tocolytic
soften uterus (stop contractions)
who dictates the definition of “mental illness”
society
the inability of the general population to understand the motivation behind a behavior.
incomprehensibility
behavior is categorized as “normal or abnormal” according to ones cultural or societal norms
cultural relativity
the walking wounded
Severely mentally ill
this population is neglected, the people who need the most care are the ones who are not getting the help bc are poor or no insurance
worried well
majority of people in therapy, see therapist bc they have the money or insurance to pay for it
homelessness
70% are linked to drug/alcohol use
pre-enlightenment
Assistance- least restrictive approach, provided food and money to help keep family intact
Banishment-wandering bands of lunatics
Confinement-most restrictive, often chained, placed on display
period of enlightenment
1790 asylums, Dorothea Dix had first asylum in US
period of scientific study
1870 shift from sanctuary to Tx
sigmound freud
classification of mental disorders
period of psychotropic drugs
1950
Thorazine: antipsychotic
Lithium: antimanic
Tofranil: antidepressant
period of community health
1960
least constrictive movement
federal funds
commitment laws
decade of the brain
1990s
