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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
c. There are at least two accelerations that peak at 15 beats above baseline and are
sustained for at 15 seconds
A woman at 38 weeks gestation is evaluated for decreased fetal movement with a
nonstress test. The test is reactive. The next step in management is to
a. allow pregnancy to continue to term with no further testing
b. continue nonstress testing each week for remainder of the pregnancy
a. allow pregnancy to continue to term with no further testing
To defferentiate respiratory from metabolic acidosis, the indicative measure is
a. higher base deficit
b. reduced oxygen saturation
c. low pH
a. higher base deficit
BD12 or higher?
No- respiratory acidemia
Yes - (a) if pCO2 elevated = yes >60 Mixed acidemia (b) No <60 = Metabolic acidemia
