EXAMINATION TEST 2026 REAL QUESTIONS
WITH FULL SOLUTIONS AND STUDY MATERIAL
◉ What is an arrhythmia? Answer: - the sporadic, irregular beats
typical of the frequent fetal events heard or recorded on the tracing
- When there is a disturbance in the heart cell's ability to form and
discharge an impulse independently (automaticity & excitability),
cardiac rhythm may become tachycardic, bradycardic, or irregular
with ectopic beats or premature rhythms such as premature atrial
contractions.
◉ How are arrythmias categorized? Answer: - based upon the
anatomical site of variant impulse formation, conduction, or a
combination of both
◉ What is the prognosis regarding arryhtmias? Answer: - Most are
benign and require no intervention
- Most will convert to a normal sinus rhythm after birth
◉ Where does the electrical impulse that governs heart rate and
rhythm originate? Answer: in the SA Node located in the right
atrium
, ◉ Where does the electrical impulse that governs heart rate and
rhythm spread from the SA node? Answer: downward to the
atrioventricular (AV) node, the bundle of His, & the Purkinje fibers
◉ What are some causes of arythmias? Answer: - 99% disappear
shortly after birth & pose no long term consequences
- Most of the patterns are premature beats
- Most are benign
- Electrolyte imbalance
- Congenital malformations of the heart
- Infection
- Acidosis
- Hydrops fetalis
◉ What are characteristics of a dysrhythmia on an FHR strip?
Answer: - Irregular but organized pattern
- Excursions can be either below or above the
baseline and look like "hatch marks"
◉ What interventions are required if you see a dysrhythmia?
Answer: - If the monitor has a logic switch, turn it to the off position
- Evaluate the FHTs with a fetoscope
- Evaluate variability between dysrhythmic episodes
