A client receiving assist control mechanical ventilation has a respiratory rate set to 14 breaths per minute. The nurse observes that the client is initiating breaths that are above the preset rate. What is the most appropriate interpretation of this situation?

The client has achieved full control of their ventilation and can stop using the ventilator.

The ventilator will not provide any assistance if the client's breathing is above the set rate.

The ventilator will assist every breath initiated by the client at whatever rate they choose.

The ventilator will adjust the set rate to match the client's spontaneous breathing rate.
