4. acceleration

3.

What is a reassuring pattern a nurse would see on an FHR tracing?

1. accelerations
2. marked variability
3. prolonged decelerations
4. absent variability

4.

What type of FHR decelerations are a sign of possible fetal descent?

1. early
2. late
3. variable
4. prolonged

5.

The advantage of this type of monitoring includes more patient mobility and freedom of movement.

1. internal electronic monitor
2. external electronic monitor
3. intermittent auscultation
4. IUPC and scalp electrode

6.

Leopold’s maneuvers allow the nurse to determine presentation and lie of the fetus. What additional information do the maneuvers provide?

1. fetal head or buttocks in the uterine fundus
2. location of the placenta
3. stage of labor
4. detection of fetal movement

7.

What is the most accurate way to monitor the FHR?

1. applying a fetal scalp electrode
2. monitoring with the external ultrasound
3. using the Doppler monitor for intermittent auscultation
4. auscultating with the fetoscope

8.

What type of monitor can measure the strength of a contraction?

1. fetal scalp electrode
2. intrauterine pressure catheter
3. toco
4. ultrasound

9.

How does the nurse document this finding?

1. uterine tachysystole
2. active labor
3. latent labor
4. tachycardia

10.

A 20-year-old, G1P0, presents to the labor and delivery unit. The patient is contracting every 5 minutes. They rate their pain as 6/10 and say the only thing that helps with the pain is walking. The patient is afraid to get into the bed because it hurts more to lie down. What type of monitoring can you offer?

1. intermittent auscultation
2. external monitoring
3. internal monitoring
4. intrauterine pressure monitoring

11.

The FHR tracing has shown moderate variability with variable decelerations over the last 30 minutes. The FHR tracing now shows minimal variability between variable decelerations. What is the probable cause of this FHR change?

1. fetal scalp stimulation
2. loss of fetal reserve
3. fetal heart block
4. fetal arrhythmia

12.

The nurse is having difficulty determining the FHR with the external monitor. A fetal scalp electrode is placed, and FHR spiking is noted. What is the cause of this abnormal tracing?

1. cardiac arrythmia
2. fetal hypoxia
3. uterine rupture
4. labor dystocia

13.

As the fetal nervous system matures, the FHR baseline changes in what way?

1. FHR decreases.
2. FHR increases.
3. Marked variability occurs.
4. Minimal variability occurs.

14.

The nurse assesses late decelerations on the FHR tracing. She enters the pregnant person’s room and notices the person lying on their back. Why should the pregnant person not lie on their back?

1. increased risk of early decelerations
2. increased risk of back pain
3. increased risk of uteroplacental insufficiency
4. increased risk of uterine labor dystocia

15.

The pregnant person recently received epidural anesthesia. The blood pressure is 90/50. What type of periodic change in the FHR is expected?

1. early deceleration
2. late deceleration
3. variable deceleration
4. sinusoidal pattern

16.

In the three-tiered categories of fetal monitoring, what characteristic does a Category II tracing have?

1. persistent late decelerations
2. variable decelerations with moderate variability
3. moderate variability with accelerations
4. baseline fetal heart rate of 80 bpm

17.

What causes decreased FHR baseline variability?

1. ampicillin
2. cocaine
3. magnesium sulfate
4. terbutaline

18.

Tachycardia is noted on the FHR tracing. What intervention will the nurse initiate?

1. Administer antibiotics.
2. Increase oxytocin.
3. Perform fetal scalp stimulation.
4. Start an IV fluid bolus.

19.

What does management of a category III fetal monitor tracing include?

1. decreasing the oxytocin by half
2. expediting birth
3. readjusting the fetal monitor
4. increasing the magnesium sulfate

20.

What nursing intervention should be initiated for an FHR tracing with early decelerations?

1. Decrease the oxytocin by half.
2. Expedite delivery.
3. Perform a vaginal exam.
4. Readjust the fetal monitor.

21.

What is the cause of late decelerations?

1. descent of fetal head
2. fetal scalp stimulation
3. imminent birth
4. uteroplacental insufficiency

22.

What is an indication for administering terbutaline?

1. early decelerations
2. insufficient labor pattern
3. tachysystole with decelerations in FHR
4. fetal tachycardia

23.

What is intrauterine resuscitation designed to treat?

1. hypertension
2. hypoglycemia
3. hyperthyroid
4. fetal hypoxia

24.

Why does the nurse turn the laboring person to a side-lying position? Select all that apply.

1. to increase contractions
2. to resolve supine hypotension
3. to reverse uterine tachysystole
4. to increase placental perfusion

25.

When is terbutaline appropriate during intrauterine resuscitation?

1. absent accelerations
2. hypotension
3. dehydration
4. tachysystole
