What is one proper action to take while administering rescue breaths?

Providing breaths every 2 seconds is the correct action while administering rescue breaths. This timing ensures that the breaths delivered are not too rapid, allowing the person receiving the breaths adequate time to exhale and receive oxygen effectively. The recommended rate helps maintain proper ventilation without causing hyperventilation or distress to the patient.

It is essential to evenly space the breaths to make them more effective and to provide a continuous and consistent supply of oxygen, particularly in an emergency when the individual may be unconscious or unable to breathe independently. Each breath should be delivered over approximately one second, allowing for adequate inflation of the lungs while still keeping the overall rhythm controlled.

In this context, the actions specified in the other options do not align with established CPR protocols. For example, sealing the mask should ideally be done with both hands to ensure an effective seal, and removing the mask interrupts the delivery of breaths. Furthermore, checking for responsiveness is a critical step in overall assessment but is not a specific action taken during the administration of rescue breaths once the rescue process has begun.
