NCC ELECTRONIC FETAL MONITORING CERTIFICATION EXAM 2026 Complete And Verified Study material) (48pages) LEARNEXAMS

What are the two types of electronic fetal monitoring and how do they differ? - The two types of electronic fetal monitoring are external and internal. External monitoring uses a transducer placed on the maternal abdomen to detect the fetal heart rate and a tocodynamometer to measure the uterine contractions. Internal monitoring uses a spiral electrode attached to the fetal scalp or other presenting part to record the fetal heart rate and an intrauterine pressure catheter to measure the uterine contractions. Internal monitoring provides more accurate and continuous data, but it requires ruptured membranes, cervical dilation, and fetal descent. It also poses a higher risk of infection and injury to the fetus. - Rationale: This question tests the students' knowledge of the basic concepts and principles of electronic fetal monitoring, which is essential for interpreting the fetal heart rate patterns and intervening appropriately. 2. What are the four categories of fetal heart rate variability and what do they indicate? - The four categories of fetal heart rate variability are absent, minimal, moderate, and marked. Absent variability means that there is no fluctuation in the fetal heart rate baseline, minimal variability means that there is less than 5 beats per minute (bpm) fluctuation, moderate variability means that there is 6 to 25 bpm fluctuation, and marked variability means that there is more than 25 bpm fluctuation. Moderate variability is considered normal and indicates a healthy fetal nervous system. Absent or minimal variability may indicate fetal hypoxia, acidosis, or neurologic impairment. Marked variability may indicate fetal stimulation, cord compression, or arrhythmia. - Rationale: This question tests the students' ability to identify and describe the different categories of fetal heart rate variability, which is one of the most important parameters for assessing fetal well-being. 3. What are the three types of decelerations in electronic fetal monitoring and what are their causes and implications? - The three types of decelerations are early, late, and variable. Early decelerations are symmetrical decreases in the fetal heart rate that coincide with the onset, peak, and end of a uterine contraction. They are caused by fetal head compression during labor and are benign and reassuring. Late decelerations are symmetrical decreases in the fetal heart rate that start after the onset, reach the lowest point after the peak, and end after the end of a uterine contraction. They are caused by uteroplacental insufficiency and
