practice Questions And Answers 100% Pass
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 - 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 - 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 - 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 - 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 - 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 - 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 - answer✔a.
are not required for the tracing to be considered normal
Myometrial compression of the spiral arteries is the underlying cause of
c. variable decelerations - 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 - 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 - 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 - 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?
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 - 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
b. cerebral cortex
c. hypothalamus - answer✔a. brain stem
A reactive nonstress test is one in which of the following occurs?
a. an acceleration sustains its peak acceleration for 15 seconds
b. At least one acceleration in first 10 minutes and 2 or more in the first 20 minutes
c. There are at least two accelerations that peak at 15 beats above baseline and are sustained
for at 15 seconds - answer✔c. There are at least two accelerations that peak at 15 beats above
baseline and are sustained for at 15 seconds
