CMA Fetal Monitoring & Assessment 3

Question 1

A sinusoidal fetal heart rate pattern is most commonly associated with:

Accepted Answer

Severe fetal anemia or hypoxia

Answer

A sinusoidal pattern — a smooth, regular, sine wave-like FHR — is an ominous finding strongly associated with severe fetal anemia or hypoxia requiring urgent evaluation.

Question 2

The contraction stress test (CST) assesses the fetal response to:

Accepted Answer

Simulated or oxytocin-induced uterine contractions

Answer

The CST evaluates uteroplacental reserve by observing FHR changes in response to contractions induced by nipple stimulation or low-dose oxytocin.

Question 3

Which maternal position is recommended first when late decelerations are observed to improve fetal oxygenation?

Accepted Answer

Left lateral decubitus

Answer

The left lateral decubitus position relieves aortocaval compression by the gravid uterus, improving maternal cardiac output and uteroplacental blood flow.

Question 4

FHR accelerations during fetal monitoring indicate:

Accepted Answer

Fetal well-being and adequate oxygenation

Answer

Accelerations are the hallmark of a reactive NST and confirm that the fetal nervous system is intact and the fetus is well-oxygenated.

Question 5

A BPP score of 6/10 at 38 weeks gestation is best interpreted as:

Accepted Answer

Equivocal — further evaluation or delivery may be indicated

Answer

A score of 6/10 is equivocal and requires clinical decision-making based on gestational age and maternal factors; delivery is often recommended at term.
