Basic Life Support (BLS) Practice Exam

What is an appropriate response if a second provider is present during CPR?

1. They should stand by and observe

2. They should provide ventilations after every 5 compressions

3. They should alternate roles in delivering compressions and ventilations

4. They should prepare to administer medications

The correct answer is: They should alternate roles in delivering compressions and ventilations

When two providers are present during CPR, it is essential to work collaboratively to ensure the best possible outcome for the patient. Alternating roles in delivering compressions and ventilations allows for continuous high-quality CPR while preventing fatigue in either provider. This team approach can keep the quality of chest compressions consistent, which is crucial for maintaining blood flow to vital organs. Research shows that effective CPR includes both high-quality chest compressions at a rate of 100 to 120 per minute and timely ventilations. By alternating every 5 cycles or about every 2 minutes, both providers can sustain their performance and responsiveness throughout the resuscitation effort. This method also ensures that both providers remain engaged and alert, increasing the likelihood of a successful outcome. Standing by and observing does not contribute to patient care and is not beneficial in a critical situation. Providing ventilations only after every 5 compressions can lead to interruptions in compressions, which is not optimal. While preparation for medication administration might be necessary at some point, it is not an immediate action during the initial CPR process, especially when compressions and ventilations are the priority.
