Final answer:
The correct volume of air to be administered during ventilations to a patient in cardiac arrest using a BVM is 300-500 milliliters (option B), which is enough to cause the chest to rise effectively.
Step-by-step explanation:
When providers are preparing to deliver ventilations to a patient in cardiac arrest using a bag-valve mask (BVM), the typical volume of air administered per ventilation is currently recommended to be approximately 500 to 600 milliliters. This volume is sufficient to cause the chest to rise, which indicates an effective breath for an adult patient. This amount also avoids the potential for complications associated with delivering too much volume, such as gastric inflation or lung damage. The answer to how much volume should be administered is therefore option B) 300-500 milliliters, which is within the recommended range
