A nurse is instructing a post-surgical client on how to use an incentive spirometer. Which of the following actions by the client demonstrate correct use of the device?
The client breathes in through the device, pauses after reaching the goal indicator, and exhales in a controlled manner.
The client exhales into the device to assess lung function and begins breathing exercises afterward.
The client takes repeated deep breaths into the device in continuous repetition without pausing.
The client blows into the device and follows this with short, quick breaths.
The correct use of an incentive spirometer involves breathing in steadily through the device to encourage lung expansion and holding the breath briefly to allow the alveoli to remain open. This helps prevent complications such as atelectasis. Exhaling into the device, taking multiple quick breaths, or focusing on blowing instead of inhaling reflect incorrect techniques because they fail to achieve the goal of lung inflation. Each technique requires calm, deliberate effort rather than rapid or forceful actions. While coughing is helpful after using the spirometer to clear secretions, it is not part of the device's intended function.
