Fetal heart rate information is measured electronically by the: - ANS-ultrasound
transducer
Oxygen transported through the bloodstream to the tissues is attached to: -
ANS-hemoglobin
An external ultrasound transducer is being used to monitor the fetal heart rate. The
audible signal indicates a heart rate of 75. The tracing shows a baseline rate of 145
beats per minute. To verify the fetal heart rate the nurse should: - ANS-palpate the
maternal pulse while auscultating the fetal heart
The best location for auscultating the fetal heart is: - ANS-over the fetal back
An advantage of the external ultrasound transducer compared with auscultation is that
the external ultrasound transducer allows you to assess: - ANS-changes in rate in
response to uterine
Which of the following uterine activity assessments can be documented using a
tocodynamometer? - ANS-frequency*
Fetal tachycardia may be caused by: - ANS-fetal immaturity*
Which of the following statements is true about the documentation of fetal heart
monitoring data? - ANS-Documentation can be time consuming, but is an essential part
of risk management
A risk management strategy that can reduce liability related to fetal heart monitoring
includes: - ANS-development of emergency drill exercises
When dealing with a conflict, it is appropriate for the nurse to: - ANS-Discuss the
situation with the primary obstetric care provider, effectively communicating the concern
and rationale for the conflict.
For the term fetus, an acceleration is a visually apparent abrupt increase in the FHR
above the baseline of at least: - ANS-15 bpm for 15 seconds
, Contraction intensity is recorded in mm Hg with an IUPC to reflect the: - ANS-total
intrauterine pressure, including the resting tone*
The time elapsed between the beginning of a contraction and the end of a contraction is
described as: - ANS-duration
If the waveforms for uterine contractions measured by an IUPC suddenly cease to be
recorded, which of the following is a possible cause for this problem? - ANS-uterine
rupture*
Normal uterine resting tone in a term pregnancy is usually: - ANS-less than or equal to
20 mm Hg
A late deceleration of the FHR is a visually apparent, usually symmetrical, gradual
decrease and return to baseline FHR associated with a uterine contraction. The gradual
decrease is defined as onset of deceleration to nadir ≥30 seconds occurring: -
ANS-after the peak of the contraction
When auscultating the fetal heart rate, the nurse should simultaneously palpate the
uterus to: - ANS-correlate changes in the fetal heart rate to uterine activity
The average range of the fetal heart rate in the absence of contractions or episodic
changes is referred to as the baseline: - ANS-rate
Which of the following methods provides the most accurate, quantifiable assessment of
uterine activity: - ANS-intrauterine pressure catheter
Hemoglobin carrying its maximum number of oxygen molecules refers to oxygen: -
ANS-saturation
The time elapsed from the beginning of one contraction to the beginning of the next
contraction is expressed as: - ANS-frequency
Uterine resting tone is the pressure within the uterus: - ANS-between contractions
To remove the fetal spiral electrode, you should: - ANS-turn the wires counterclockwise
until the electrode is dislodged
The amount of oxygen a fetus receives in excess of its basal needs is referred to as: -
ANS-fetal reserve
