NCC EFM EXAM NEWEST 2024 REAL EXAM 2 VERSIONS
(VERSION A AND B) 300 QUESTIONS AND DETAIED
ANSWERS (100% VERIFIED ANSWERS) |ALREADY
GRADED A+
Polyhydramnios - ANSWER: single MVP > 8 cm or AFI >24; 1% of pregnancies; 60%
idiopathic; multiple gestation, maternal diabetes, hydrops, anomalies, TORCH; ass'd
with cardiac/GI issues/renal issues
Oligohydramnios - ANSWER: single MVP < 2 cm or AFI < 5 at term (less than 5%ile);
associated with FGR, placental abnormalities, urinary tract abnormalities, post-term
pregnancies, ruptured or idiopathic membranes
Doppler - ANSWER: US transducer, depicts valve closure; uses autocorrelation
Autocorrelation - ANSWER: successive US waveforms at many points; current
technology which is more accurate at detecting FHR variability; controls artifact
sound waves
Toco/tocotransducer - ANSWER: detects change in contour with contractions; place
at fundus or at area of maximum palpation; difficult to measure with obesity,
polyhydramnios
Fetal scalp electrode measures - ANSWER: R-R waves; still has issues with artifact;
risk of injury, measuring maternal HR in instance of fetal demise; rupture and
dilation required
IUPC - ANSWER: solid>fluid filled tips, measures mmHg and allows amnioinfusion;
issue with displacement, perforation, placental abruption
Intermittent auscultation - ANSWER: goal is baseline 110-160, +/-accels, no decels; if
present, put on continuous monitor min 20 minutes); cannot determine variability or
types of FHR decels
Active phase auscultation - ANSWER: q15 min for high risk up to q30min
Second stage auscultation - ANSWER: q5 min if high risk up to q15min
Fetal tolerance of labor - ANSWER: auscultate after a contraction x 30-60 seconds;
document rate, rhythm, accels, decels
Doppler vs. fetoscope - ANSWER: doppler uses autocorrelation and detects valve
closure; fetoscope listens through opening in heart wall?
, Signal ambiguity - ANSWER: confusing maternal and fetal heart rate; common with
repositioning, fetal movement, during pushing (maternal tachycardia); can occur
even with fetal demise due to FSE recording maternal blood flow through the
placenta
Suspect signal ambiguity - ANSWER: when there is lower baseline or >50%
contractions with accelerations (especially with pushing); verify and document
maternal heart rate via pulse oximetry
Halving/doubling - ANSWER: Halving occurs if FHR >180-200; may double if rate <50
Normal blood flow pathway - ANSWER: Blood from maternal vein > intervillous pool
of maternal blood > umbilical vein (oxygenated blood)
Normal placenta - ANSWER: Placenta has 15-20 lobules on maternal surface;
Decreased surface area of chorionic villi from abnormal development, infection,
thrombosis, hemorrhage, inflammation (chorio increases risk of CP), degenerative
changes with increasing gestational age (calcifications)/HTN/DM - can cause IUGR,
hypoxia, FHR decels
Acute drop in placental function - ANSWER: fetal asphyxia
Chronic drop in placental function - ANSWER: FGR
O2 and CO2 - ANSWER: simple transport (diffusion); electrolytes, fat soluble
vitamins, narcotics, anesthetic gasses, antibiotics
Glucose - ANSWER: facilitated transport, by carrier molecules
Active - ANSWER: amino acids, calcium, iron, water soluble vitamins (uses ATP)
Fetal circulation - ANSWER: when compromised, fetal blood redistributed to heart,
brain, adrenals; shunting and FHR increase compensate for decreased blood flow
and hypoxemia; limit mixing of oxygenated and deoxygenated blood
