A patient is placed on volume-cycled ventilation. The nurse plans care for this client based on which characteristic of this method of ventilation?
1. A set volume will be delivered, which will help overcome the client's airway resistance changes.
2. There is no need for placement of an artificial airway.
3. The volume delivered by the ventilator will vary depending upon pressure changes.
4. This type of ventilator is able to deliver higher oxygen levels than other types.

The answer is 1
Rationale:
1. Volume-cycled ventilation delivers a preset volume of gas to the lungs, making volume constant and pressure variable. The ventilator will deliver the volume of gas regardless of the pressure it requires, overcoming the changes in lung compliance and airway resistance.
2. All four ventilator cycling mechanisms, pressure-cycled, volume-cycled, time-cycled, and flow-cycled, require an artificial airway.
3. Pressure-cycled ventilation delivers a present pressure of gas to the lungs. The volume of air delivered varies with the lung's compliance and airway's resistance.
4. All ventilator cycling mechanisms are able to deliver up to 100% oxygen.
