CPR Neonatal Resuscitation 3 — Questions and Answers
Question 1: At what heart rate should chest compressions be started in a newborn?
- Below 60 bpm despite 30 seconds of effective PPV (Correct answer)
- Below 100 bpm
- Below 80 bpm
- Immediately at birth if not crying
Correct answer: Below 60 bpm despite 30 seconds of effective PPV
Chest compressions begin when the heart rate remains below 60 bpm after 30 seconds of effective ventilation, ideally with an advanced airway.
Question 2: What is the recommended compression-to-ventilation ratio for a newborn requiring chest compressions?
- 3 compressions to 1 ventilation (Correct answer)
- 15 compressions to 2 ventilations
- 30 compressions to 2 ventilations
- 5 compressions to 1 ventilation
Correct answer: 3 compressions to 1 ventilation
Neonatal resuscitation uses a 3:1 ratio, delivering 90 compressions and 30 breaths per minute.
Question 3: Which technique is preferred for delivering chest compressions in a newborn?
- Two-thumb encircling hands technique (Correct answer)
- Two-finger technique
- Heel of one hand
- Two hands stacked
Correct answer: Two-thumb encircling hands technique
The two-thumb encircling hands technique is preferred because it generates better blood pressure and is less tiring.
Question 4: To what depth should the chest be compressed during neonatal CPR?
- About one-third the anterior-posterior diameter of the chest (Correct answer)
- About one-half the chest diameter
- About 2 inches
- About 1 inch fixed depth
Correct answer: About one-third the anterior-posterior diameter of the chest
Compressions should depress the chest approximately one-third of its anterior-posterior diameter.
Question 5: When chest compressions are started, what oxygen concentration should be used?
- 100% oxygen (Correct answer)
- 21% room air
- 40% oxygen
- 60% oxygen
Correct answer: 100% oxygen
Once compressions begin, oxygen should be increased to 100% until the heart rate recovers.
Question 6: On what landmark of the newborn's chest are compressions delivered?
- Lower third of the sternum, just below the nipple line (Correct answer)
- Upper third of the sternum
- Over the xiphoid process
- Left side over the heart
Correct answer: Lower third of the sternum, just below the nipple line
Compressions are delivered on the lower third of the sternum, below an imaginary line between the nipples.
Question 7: After starting compressions, how often should the heart rate be reassessed?
- Every 60 seconds (Correct answer)
- Every 15 seconds
- Every 30 seconds
- Every 2 minutes
Correct answer: Every 60 seconds
Heart rate is reassessed after about 60 seconds of coordinated compressions and ventilations to allow time for recovery.
