Relias - Fetal Heart Monitoring Latest Update 2023-2024 Questions and Verified Correct Answers Already Passed
(1) hypoxemia vs. (2) hypoxia - Correct Answer:1 - reduce O2 in blood
- - reduced O2 delivery at tissue level
absent variability - Correct Answer:- if there are recurrent or late decels w/absent variability that equals cat 3 strip
- if absent variability without recurrent variable or late decels that is a cat 2 tracing but
does require prompt eval and surveillance
accelerations - Correct Answer:for 32+ wks gestation it is a 15 by 15 accel
before 32 wks: 10x10
prolonged is lasting 2+ mins and < 10 mins (if longer, bsl change)
acidemia - Correct Answer:assoc w/ widespread, deleterious effects on vital organ and body function
acidosis - Correct Answer:pH below 7.35
pH is low
(acidosis is the process that leads to low blood pH, or acidemia)
acute total or near total hypoxia is assoc w/damage to - Correct Answer:midbrain and brainstem
adequate labor MVU amount - Correct Answer:200-250 MVUs
alkalosis - Correct Answer:pH above 7.45
pH is high
amnioinfusion requirements - Correct Answer:- ROM
- IUPC
Can reduce incidence of variable decels but doesnt help with late decels or bsl variability
artery values (fetus to placenta) - Correct Answer:Normal ranges: 1 / 2
pH 7.20-7.28
pCO2 35-70
Base excess -3 to -9
base excess and base deficit - Correct Answer:- base deficit is expressed as a positive number
- base excess is expressed as a negative number
~ they are equivalent and terms are used interchangeably ~
buffers - Correct Answer:- help maintain acid base homeostasis
- 2 major fetal buffers are plasma bicarbonate and hgb
capabilities of iupc - Correct Answer:- able to assess adequacy of contractions by calculating MVUs
- can be used for amnioinfusion
cat 1 tracing - Correct Answer:- normal bsl FHR
- moderate variability
- no variable or late decels or prolonged decel
- early decels ok
cat 2 tracing - Correct Answer:indeterminate patterns, includes:
- bsl rate abnormalities: tachy; brady w/out absent variability
- abnormalities in variability: minimal or absent without recurrent variable, late or
prolonged decels
- presence of intermittent variable or late decels with any variability
- prolonged decel
*tachysystole is not a consideration but may be a cause
cat 3 tracing - Correct Answer:patterns include:
- absent variability w/recurrent late decels
- recurrent variable decels
- bradycardia
- sinusoidal fhr
