The US transducer on the EFM measures the

• Electrical signal of the fetal heart
• Mechanical movement of the fetal heart reflected off of sound waves
• R to R intervals of the fetal heart - Correct Answer b. Mechanical movement of the

fetal heart reflected off of sound waves The purpose of the autocorrelation in external monitoring is to

• Compare incoming waveforms for comparison
• Decrease signal to noise levels
• Distinguish fetal from maternal heart rate - Correct Answer a. Compare incoming

waveforms for comparison The area of maximum intensity of FHR is usually the fetal

• Back

• Intrauterine pressure catheter
• Manual palpation
• Maternal perception - Correct Answer a. Intrauterine pressure catheter

When educating the patient about fetal monitoring, the most appropriate statement is

• A normal tracing indicates that your baby is well-oxygenated
• A normal tracing indicates that you have a healthy baby
• Continuous fetal monitoring will insure a better outcome for your baby - Correct

Answer a. A normal tracing indicates that your baby is well-oxygenated In comparison to maternal blood, the affinity of fetal blood for oxygen is

• Higher
• Lower
• The same - Correct Answer a. Higher 1 / 2

The process that requires energy to accomplish the passage of substances within the intervillous space is

• Active transport
• Diffusion
• Facilitated diffusion - Correct Answer a. Active transport

The umbilical vein carries

• Carbon dioxide from the fetus back to the placenta
• Deoxygenated blood from the fetus to the placenta
• Oxygenated blood from the placenta to the fetus - Correct Answer c. Oxygenated

blood from the placenta to the fetus Fetal hypoxia is best described as a condition of

• Decreased oxygen in the blood
• Decreased oxygen in the tissue
• Increased hydrogen ions in the blood - Correct Answer b. Decreased oxygen in the

tissue Stimulation of the PNS causes the FHR to

• Decrease
• Increase
• Remain the same - Correct Answer a. Decrease

Chemoreceptors respond mainly to changes in

• Blood pressure
• Hormonal leves
• Oxygen and CO2 levels - Correct Answer c. Oxygen and CO2 levels

The fetus responses to a significant drop of PO2 by

• Increasing oxygen consumption
• Reducing lactic acid production
• Shifting blood to vital organs - Correct Answer c. Shifting blood to vital organs

Activation of fetal peripheral chemoreceptors results in which FHR change

• Decrease
• Increase
• No change - Correct Answer a. Decrease

A patient receiving oxytocin has 17 ctx in 30 minutes, according to the NICHD guidelines this is called

• Hyperstimulation
• Hypertonus
