護理師教導病人使用誘發性肺量計（Incentive Spirometer）。下列哪些說明是正確的？（選所有適合的）
A nurse is teaching a client to use an incentive spirometer. Which instructions are correct? (Select all that apply.)
- AInhale slowly and deeply✓ 正解緩慢且深吸氣
- BExhale forcefully into the device用力向裝置內吐氣
- CHold your breath for 3 to 5 seconds after inhalation✓ 正解吸氣後閉氣 3 至 5 秒
- DPerform the exercise 5 to 10 times every hour while awake✓ 正解清醒期間每小時進行 5 至 10 次
- EUse the device immediately after eating a large meal在大餐後立即使用該裝置
誘發性肺量計（Incentive spirometer）旨在促進深呼吸以擴張肺泡，預防手術後肺塌陷。護理指導應強調：必須「慢且深」地吸氣（吸氣訓練），而非強烈吐氣；吸氣後閉氣 3-5 秒，以增加氣體交換機會；頻率為每小時醒時執行 5-10 次。剛吃飽後執行易導致噁心嘔吐，故應避開飯後時間。這些步驟能有效維持術後呼吸功能。
An incentive spirometer is designed to promote deep breathing and expand the alveoli, preventing postoperative atelectasis. Nursing instructions should emphasize: inhaling slowly and deeply (inspiratory training) rather than exhaling forcefully; holding the breath for 3-5 seconds after inhalation to allow more time for gas exchange; and performing the exercise 5-10 times per hour while awake. Using the device immediately after a large meal may cause nausea and vomiting and should be avoided. These steps effectively support recovery of respiratory function after surgery.
