Question 1
The paper speed used with EFM in North America is:
A. 1 cm/min
B. 2 cm/min
C. 3 cm/min
D. 5 cm/min
Answer: C
EXPLANATION: Standard EFM paper speed in North America is 3 cm per minute to allow for consistent
interpretation of fetal heart rate (FHR) patterns.
Question 2
The US transducer on the EFM measures the:
A. Electrical signal of the fetal heart
B. Mechanical movement of the fetal heart reflected off of sound waves
C. R to R intervals of the fetal heart
D. Pressure within the uterus
Answer: B
EXPLANATION: The ultrasound transducer detects mechanical movement, not electrical activity, to
generate the fetal heart rate from Doppler signals.
Question 3
The purpose of the autocorrelation in external monitoring is to:
A. Compare incoming waveforms for comparison
B. Decrease signal to noise levels
C. Distinguish fetal from maternal heart rate
D. Measure uterine pressure
Answer: A
EXPLANATION: Autocorrelation algorithms help smooth Doppler signals by comparing waveforms to
determine heart rate patterns accurately.
,Question 4
The area of maximum intensity of FHR is usually the fetal:
A. Back
B. Chest
C. Umbilicus
D. Buttocks
Answer: A
EXPLANATION: The fetal back is the optimal location for picking up heart tones using external fetal
monitoring.
Question 5
Palpating the uterus is best performed by using the:
A. Back of hand
B. Fingertips
C. Palm
D. Elbow
Answer: B
EXPLANATION: Fingertips offer better sensitivity and precision for assessing uterine tone and
contractions.
Question 6
What is the most sensitive method of assessing uterine activity?
A. Intrauterine pressure catheter
B. Manual palpation
C. Maternal perception
D. Tocodynamometer
Answer: A
EXPLANATION: An intrauterine pressure catheter provides direct and quantitative data on uterine
pressure, making it the most sensitive method.
Question 7
When educating the patient about fetal monitoring, the most appropriate statement is:
A. A normal tracing indicates that your baby is well-oxygenated
B. A normal tracing indicates that you have a healthy baby
C. Continuous fetal monitoring will insure a better outcome for your baby
D. We are always able to detect all problems with this monitoring
Answer: A
, EXPLANATION: A normal tracing typically reflects adequate fetal oxygenation, though not absolute fetal
health.
Question 8
In comparison to maternal blood, the affinity of fetal blood for oxygen is:
A. Higher
B. Lower
C. The same
D. Unmeasurable
Answer: A
EXPLANATION: Fetal hemoglobin has a higher affinity for oxygen, helping the fetus extract oxygen more
efficiently from maternal blood.
Question 9
The process that requires energy to accomplish the passage of substances within the intervillous space
is:
A. Active transport
B. Diffusion
C. Facilitated diffusion
D. Osmosis
Answer: A
EXPLANATION: Active transport uses energy (ATP) to move substances across placental membranes
against a concentration gradient.
Question 10
The umbilical vein carries:
A. Carbon dioxide from the fetus back to the placenta
B. Deoxygenated blood from the fetus to the placenta
C. Oxygenated blood from the placenta to the fetus
D. Nutrients to the maternal circulation
Answer: C
EXPLANATION: The umbilical vein delivers oxygenated, nutrient-rich blood from the placenta to the
fetus.
Question 11
Fetal hypoxia is best described as a condition of:
A. Decreased oxygen in the blood
B. Decreased oxygen in the tissue
