AWHONN FETAL HEART RATE MONITORING ACTUAL EXAM 2025 |
49 QUESTIONS WITH CORRECT ANSWERS
Normal Fetal Heart Rate is between and beats per
minute. 60, 100
100, 140
110, 160
125, 180
1. Explain the significance of using a tocodynamometer in monitoring labor
progress.
It helps in assessing fetal heart rate patterns.
It provides information about uterine contractions and their
intensity.
It measures maternal oxygen levels.
It evaluates the position of the fetus.
It determines the need for cesarean delivery.
2. Which physiologic event results in the initial compensatory rise in the fetal
heart rate during a variable deceleration?
Acute increase in uterine tone
Occlusion of the umbilical vein
Occlusion of the umbilical artery
Occlusion of all umbilical vessels
3. What physiological response occurs when fetal arterial pressure decreases
below normal levels?
Increased heart rate due to baroreceptor activation
,Decreased heart rate due to baroreceptor activation
, Increased heart rate due to decreased vessel distension
Decreased heart rate due to increased vessel distension
4. Explain what mixed acidemia indicates about the fetal condition based on
the provided cord blood gas results.
It suggests the fetus is in a state of metabolic alkalosis.
It indicates a combination of respiratory and metabolic acidosis.
It reflects normal fetal acid-base balance.
It shows only respiratory acidosis without metabolic involvement.
5. Explain the physiological consequences of umbilical cord compression on
fetal blood gas levels.
It leads to increased oxygen levels and decreased CO2 levels.
It causes CO2 accumulation, resulting in respiratory acidosis.
It has no significant effect on fetal blood gas levels.
It improves maternal-fetal circulation.
6. What is a key characteristic of variable decelerations in fetal heart rate
monitoring?
The deceleration occurs gradually over time
The deceleration is associated with maternal anxiety
The onset of the deceleration is abrupt
The deceleration is always accompanied by fetal movement
7. What is the initial step in evaluating a fetal heart rate (FHR) tracing?
Identify variable decelerations
Establish the baseline rate
Assess uterine contractions
