NCC EFM fetal monitoring practice
quizzes part 1
1. A woman in the first stage of labor is to have a direct fetal scalp electrode
placed.
The fetal presenting part is not engaged but membranes have been ruptured.
Placement of the fetal scalp electrode increases the risk of
a. cord prolapse
b. prolonged labor
c neonatal hematoma - correct answer ✔a
2. When variable decelerations persist despite intrauterine resuscitation, a
factor that would lead to consideration of letting labor continue to delivery is
a. acceleration after vibroacoustion
b. regular fetal breathing motions
c. no tachysystole - correct answer ✔a
A characteristic of a sinusoidal heart rate pattern is
a. amplitude of 5 to 15 beats/min above and below the baseline
b. a fixed baseline variability range for 10 or more minutes
c. bradycardia with regular oscillation pattern - correct answer ✔a
Since the introduction of electronic fetal monitoring, what effects have
occurred?
,a. Better early detection of hypoxic ischemic encephalopathy
b. Decreased incidence of cerebral palsy
c. Increased incidence of cesarean delivery - correct answer ✔c. Increased
incidence of cesarean delivery
Oligohydramnios is defined on the biophysical profile as
a. amniotic fluid index falling below the threshold of 5 cm
b. no single measurable vertical pocket of fluid greater than 2 cm
c. all four quadrant pockets of fluid being less than 6 cm - correct answer ✔b.
no single measurable vertical pocket of fluid greater than 2 cm
The optimal antepartum fetal testing strategy would identify an at risk fetus
prior to an irreversible event while
a. cinfirming fetal viability
b. minimizing iatrogenic prematurity
c. preventing progression of fetal complications - correct answer ✔b.
minimizing iatrogenic prematurity
Accelerations on the electronic fetal monitoring in the intrapartum period
a. are not required for the tracing to be considered normal
b. must show 15 beats x 15 seconds acceleration to be categorized as such
c. normal EFM tracings without accelerations are assigned a category II
designation - correct answer ✔a. are not required for the tracing to be
considered normal
,Myometrial compression of the spiral arteries is the underlying cause of
a. late decelerations
b. sinusoidal pattern
c. variable decelerations - correct answer ✔a. late decelerations
The physiologic basis of the biophysical profile is that fetal movement
decreases with
a. depressed central nervous system
b. increasing hypoxia
c. reduced cardiac function - correct answer ✔b. increasing hypoxia
There are different criteria for nonstress test evaluation between preterm and
term fetuses because in the preterm fetus
a. heart rate is often increased
b. magnitude of accelerations can vary over time
c. fetal heart rate variability is more sensitive to uterine - correct answer ✔b.
magnitude of accelerations can vary over time
The minimal baseline duration on an electronic fetal monitor must be at least 2
minutes in any given window for how many minutes?
a. 5
b. 10
c. 20 - correct answer ✔b. 10
, To determine if a fetal heart rate tracing should be assigned a category III
designation absent variability, which of the following should be present?
a. bradycardia
b. tachycardia
c. prolonged deceleration - correct answer ✔a. bradycardia
Category III FHR tracings include either
- Absent baseline FHR variability and any of the following:
> recurrent late decelerations
> Recurrent variable decelerations
> Bradycardia
- Sinusoidal pattern
There are often small increases in fetal heart rate that precede and follow
variable decelerations because the compression of umbilical vein can cause
tachycardia secondary to decreased
a. myocardial response
b. preload
c. systemic vascular resistance - correct answer ✔b. preload
The fetal heart rate (FHR) is controlled by the fetal central nervous system
and mediated by sympathetic or parasympathetic nerve impulses originating
in the fetal
a. brain stem
