BSN 346 EXAM 5 QUESTIONS AND
CORRECT ANSWERS!!
Question 1 of 3
Which uterine contraction intensity classification is defined as a firm but not rigid fundus
that is difficult to indent with fingertips?
Mild
Strong
Normal
Moderate
Moderate
A moderate-strength contraction means a firm fundus that is difficult to indent with fingertips
(feels like touching a finger to a chin).
Question 2 of 3
Which methods are used to assess uterine activity externally?
Select all that apply.
Fetal scalp electrode
Ultrasound transducer
Palpation
Intrauterine pressure catheter
Tocodynamometer
Palpation
Palpation is an external method of assessing uterine activity. If using external electronic fetal
monitoring, palpation is needed to assess contraction intensity and uterine resting tone.
The tocodynamometer (toco) is an external method to monitor uterine activity. The toco
measures uterine contraction frequency and duration; palpation is needed to assess intensity and
uterine resting tone.
Question 3 of 3
Which uterine resting tones are considered reassuring?
,Select all that apply.
18 mm Hg with an intrauterine pressure catheter (IUPC)
45 mm Hg with an intrauterine pressure catheter (IUPC)
350 Montevideo units with electronic fetal monitoring (EFM)
300 Montevideo units with fetal scalp electrode (FSE)
Less than 810 Montevideo units (MVUs) as measured externally
18 mm Hg with an intrauterine pressure catheter (IUPC)
The average uterine resting tone is expected to be less than 20 mm Hg if measured with the
IUPC. This would be a reassuring finding.
350 Montevideo units with electronic fetal monitoring (EFM)
The average uterine resting tone is expected to be less than 400 Montevideo units by internal
EFM with an intrauterine pressure catheter (IUPC). This would be a reassuring finding.
Question 1 of 3
Which fetal heart rate classification is considered nonreassuring?
Category I
Category II
Category III
Category IV
Category III
Category III classification refers to abnormal findings that are nonreassuring.
Question 2 of 3
The nurse caring for the patient in labor understands that absent (or minimal) variability
is usually considered nonreassuring. However, which condition related to decreased
variability is considered benign?
Metabolic acidemia
Central nervous system (CNS) depressant effects
Fetal sleep
Local anesthetic agent effects
,Fetal sleep
Fetal sleep states are benign causes of absent baseline variability. The episodes are usually 40
minutes or less and happen occasionally.
Question 3 of 3
Match the type of nonreassuring deceleration with the associated cause.
Disrupted oxygen transfer
-Late
Interrupted oxygen supply
-Prolonged
Umbilical cord compression
-Variable
Question 1 of 3
When is fetal heart rate (FHR) and uterine activity (UA) assessment indicated for a low-
risk patient in the first stage of labor?
Every 5 to 15 minutes
After rupture of membranes
After administration of oxytocin
Every 2 hours
After rupture of membranes
FHR and UA should be assessed after rupture of membranes to assess fetal response to rupture
and whether UA changes.
Question 2 of 3
The nurse is assessing the fetal heart rate of a woman who is currently lying supine and
identifies a nonreassuring pattern. Which recommendation would the nurse make to
address this pattern?
"Elevate your legs."
"Turn on your side."
"Walk around the room to reposition the fetus."
"Remain on your back, and we will reassess in an hour."
, "Turn on your side."
The patient should not lie supine, because compression of the aorta could negatively affect the
fetus. A change of position, such as lying on the side, is the first response to a nonreassuring fetal
heart rate pattern in this situation.
Question 3 of 3
The nurse is caring for a woman who is receiving oxytocin. The data displayed on the
electronic fetal monitor shows that the contractions are approximately 10 seconds apart.
Which intervention would the nurse perform next?
Stop the oxytocin.
Call the health care provider.
Reposition the woman to her side.
Administer oxygen to the patient.
Stop the oxytocin.
One of the side effects of oxytocin or other uterine stimulants is excessive uterine activity, which
can be harmful to the patient and fetus. Therefore the first action would be to stop the
medication.
Question 1 of 3
The nurse is monitoring a patient in the active stage of labor with internal fetal monitoring.
The patient has been experiencing contractions that last 70 to 90 seconds and occur every 1
to 2 minutes, and she has a uterine resting tone of 25 mm Hg. The nurse recognizes that the
patient is experiencing which type of difficult labor?
Hypotonic
Precipitous
Tachysystole
Postterm labor
Tachysystole
Tachysystole, or hypertonic uterine dysfunction, is a potential complication of labor induction. It
is defined by an increase in the uterine resting tone or more than 5 uterine contractions in a 10-
minute time frame.
