NCC EFM Exam Breakdown & Complete Study Guide (Updated) | Latest 2023/2024 Content on exam -- -Pattern recognition & intervention: 70% -Physiology: 11% -Fetal assessment methods: 9% -EFM equipment: 5% -Professional issues: 5% Pattern recognition & intervention -- -FHR baseline -FHR variability -FHR accelerations -FHR decelerations -Normal uterine activity -Abnormal uterine activity -Fetal dysrhythmias -Maternal complications -Uteroplacental complications -Fetal complications FHR Descriptors -- 1) Baseline 2) Variability 3) Presence of accels 4) Presence of decels 5) Changes in trends overtime FHR Baseline -- Average FHR rounded to nearest 5 during a 10 min window -110 to 160 -excludes accels, decels, & marked variability -must have 2 mins to identify as a baseline (doesn't need to be continuous) Fetal Bradycardia -- <110 for ≥10 min -Causes: hypotension (ex: after epi), cord prolapse, head compression, congenital defect, rapid descent, abruption or rupture, tachysystole, post dates, hypoglycemia, lupus (heart block) -With ↓ O2, blood will be shunted to brain, heart, & adrenals, eventually ↓ FHR to ↓ O2 demands of heart muscle -Verify not mom's HR, vaginal exam (r/o prolapse), resuscitate, evaluate arrhythmia, expedite delivery Fetal Tachycardia -- >160 for ≥10 min -Causes: fetal anemia, maternal fever or infection, fetal immaturity (preterm), SVT, maternal anxiety (catecholamines), dehydration, hyperthyroid, hypoxia -Med causes: terbutaline, catecholamines (epinephrine, norepi) -Assess mom's temp & infection risk (GBS, PROM) FHR Variability -- Irregular in amplitude & frequency, quantified by peak to trough -Caused by sympathetic vs parasympathetic, r/t neuro maturity -Less in preterm due to undeveloped CNS -Absent: undetectable, flat -Minimal: ≤5 bpm but detectable -Moderate: 6-25 bpm -Marked: >25 bpm (indeterminate baseline), signific
