How close are these to the actual C-EFM?

Per NCC, the C-EFM is a 2-hour, 125-item exam: 100 scored plus 25 unscored pretest
questions. It is dominated by one domain — Pattern Recognition and Intervention at
70% — with Physiology (11%), Fetal Assessment Methods (9%), EFM Equipment (5%), and
Professional Issues (5%) filling the rest. In short: if you can read a tracing and pick the
right next action, you pass. The samples below train exactly that.

Sample C-EFM questions

  1. A multipara at 33 weeks with severe preeclampsia is on magnesium sulfate at
    2 g/hr. The FHR baseline is 135 bpm with minimal variability and no accelerations, and
    no decelerations. What best explains the tracing?

    • A. Expected central nervous system depression from the medication
    • B. Metabolic acidemia requiring immediate intervention
    • C. A sleep cycle that has exceeded normal duration
    • D. Severe chronic placental insufficiency and hypoxemia

    Answer: A. Magnesium sulfate is a CNS depressant that crosses the
    placenta, commonly reducing variability and suppressing accelerations without indicating
    hypoxia or acidosis. With no decelerations present, the medication is the most likely
    explanation — document, keep watching, and resist over-treating a drug effect.

  2. A G1P0 at 38 weeks with severe preeclampsia on magnesium sulfate shows minimal
    variability and recurrent late decelerations. Coarse crackles are noted on auscultation.
    Which fluid-management action is correct?

    • A. Administer a 1,000 mL fluid bolus immediately to improve placental perfusion
    • B. Prioritize lateral positioning and restrict total IV intake to about 125 mL/hr
    • C. Give IV labetalol 20 mg to rapidly improve uteroplacental blood flow
    • D. Increase magnesium sulfate to 3 g/hr for seizure prophylaxis

    Answer: B. Severe preeclampsia brings endothelial damage and low colloid
    oncotic pressure, so pulmonary edema is a standing threat — and the crackles say it is
    already starting. A large bolus would flood the lungs. Lateral positioning plus fluid
    restriction addresses both the tracing and the airway risk.

  3. A client at 37 weeks with suspected IUGR has a biophysical profile: NST
    non-reactive, three body movements, one episode of tone, no breathing movements, adequate
    fluid. What is the score and next step?

    • A. Score 6/10; prepare for induction of labor
    • B. Score 6/10; repeat the BPP in 24 hours
    • C. Score 8/10; discharge with close follow-up
    • D. Score 4/10; perform immediate cesarean section

    Answer: A. Score it: NST 0, breathing 0, movement 2, tone 2, fluid 2 =
    6/10 — equivocal. At term (37 weeks) with a growth-restricted fetus already suspected
    of chronic compromise, the balance tips toward delivery rather than another 24 hours of
    waiting; induction preparation is the standard move.
