ATI CAPSTONE OB 51 2026 REVISION NOTES
AND STRUCTURED OBSTETRICS OVERVIEW
GUIDE
◉ normal FHR. Answer: 110-160 w/ increases and decreases from
baseline
◉ continuous electronic fetal monitoring. Answer: - accomplished by
securing an ultrasound transducer over the clients abdomen, which
records the FHR pattern and a tocotransducer on the fundus that
records the uterine contraindications
◉ indications for electronic fetal monitoring. Answer: - multiple
gestations
- oxytocin infusion
- placenta previa
- fetal bradycardia
- maternal complications
- intrauterine growth restriction
- post-date gestation
- active labor
- meconium stained amniotic fluid
,- abruptio placentae
- abnormal nonstress test or contraction stress test
- abnormal uterine contractions
- fetal distress
◉ Three Tier System. Answer: - fetal monitoring system with FHR
interpretation system
◉ - category 1. Answer: - baseline FHR of 110-160 /min
- baseline FHR variability: moderate
- accelerations present or absent
- early decelerations: present or absent
- variable/late decelerations: absent
◉ Category 2. Answer: - tracings include all FHR tracings not
categorized as category 1 or 3.
- baseline rate (tachycardia, bradycardia not accompanied by absent
baseline variability)
- baseline FHR variability (minimal baseline variability, absent
baseline variability not accompanied by recurrent decelerations,
marked baseline variability)
- episodic or periodic decelerations ( prolonged FHR decel equal or
greater than 2 min but less than 10 min, recurrent late decelerations
, w/ moderate baseline variability, recurrent variable decels w/
minimal or moderate baseline variability
- variable decels w/ additional characteristics including overshoots,
shoulders, or slow return to baseline FHR
◉ category 3. Answer: - FHR tracings include either sinusoidal
pattern, absent baseline FHR variability (recurrent late/variable
decels, bradycardia)
- increment, acme, decrement
◉ increment uterine contractions. Answer: - beginning of the
contraction as intensity is increasing
◉ adme uterine contractions. Answer: - peak intensity of the
contraction
◉ - decrement uterine contractions. Answer: - the decline of the
contraction intensity as contraction is ending
◉ accelerations. Answer: - Variable transitory increase in the FHR
above baseline
◉ causes of accelerations. Answer: - healthy fetal/placental
exchange
