Basic Fetal Heart Monitoring
Questions and Answers | Latest
Update | Passed
Fetal heart rate information is measured electronically by the:
✓ ultrasound transducer
Oxygen transported through the bloodstream to the tissues is attached to:
✓ 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:
✓ palpate the maternal pulse while auscultating the fetal heart
The best location for auscultating the fetal heart is:
✓ over the fetal back
An advantage of the external ultrasound transducer compared with auscultation is that the
external ultrasound transducer allows you to assess:
✓ changes in rate in response to uterine
Which of the following uterine activity assessments can be documented using a
tocodynamometer?
✓ frequency*

Which of the following statements is true about the documentation of fetal heart
monitoring data?
✓ 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:
✓ development of emergency drill exercises
When dealing with a conflict, it is appropriate for the nurse to:
✓ 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:
✓ 15 bpm for 15 seconds
Contraction intensity is recorded in mm Hg with an IUPC to reflect the:
✓ 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:
✓ 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?
✓ uterine rupture*
