A nurse is teaching a client how to use an incentive spirometer. Which of the following statements should the nurse make?

Choice A reason: Inhaling through the incentive spirometer 10 times per use is a general guideline, but the emphasis is on slow, deep inhalations, not a specific number of repetitions. The goal is to expand alveoli and prevent atelectasis, but the exact number varies by protocol. Holding the breath is more critical than the number of inhalations. Choice B reason: Sitting at a 30-degree angle is incorrect, as clients should be upright (60-90 degrees) during incentive spirometry to maximize lung expansion. A semi-upright or supine position limits diaphragmatic movement and lung capacity, reducing the device’s effectiveness in improving ventilation and preventing postoperative pulmonary complications. Choice C reason: Holding the breath for 5-7 seconds after inhaling through the incentive spirometer sustains alveolar expansion, promoting gas exchange and preventing atelectasis. This technique maximizes lung volume and strengthens respiratory muscles, critical for postoperative or immobile clients, making it a key instruction for effective spirometer use. Choice D reason: Using the incentive spirometer once every 4 hours is insufficient. Standard protocols recommend use every 1-2 hours while awake, typically 10 breaths per session, to maintain lung expansion and prevent complications like pneumonia. Less frequent use reduces efficacy, making this an incorrect instruction for optimal respiratory health.
