A nurse is teaching a preoperative patient how to use an incentive spirometer. Which instruction should be included in the education to the patient?
A.
Encourage the patient to perform incentive spirometry at least once a shift.
B.
Instruct the patient to inhale normally and then place the lips securely around the mouthpiece and exhale quickly.
C.
Instruct the patient to inhale slowly and as deeply as possible through the mouthpiece without using the nose.
D.
Instruct the patient to exhale slowly as possible through the mouthpiece without using the nose.
The correct answer and Explanation is :
The correct answer is:
C. Instruct the patient to inhale slowly and as deeply as possible through the mouthpiece without using the nose.
Explanation:
Incentive spirometry is a common respiratory therapy intervention used to promote lung expansion and prevent complications such as atelectasis (collapse of part or all of the lung) after surgery, especially for patients undergoing abdominal or thoracic surgery. The device encourages patients to take deep breaths and inflate their lungs to maintain proper respiratory function.
Rationale for Correct Instruction (Option C):
When using an incentive spirometer, the goal is for the patient to take slow, deep breaths to maximize lung expansion. Instructing the patient to inhale slowly and deeply through the mouthpiece without using their nose ensures that the lower lobes of the lungs are properly ventilated. This technique helps to prevent shallow breathing, which can lead to postoperative pulmonary complications.
- Deep breaths allow the alveoli, the small air sacs in the lungs, to fully expand, improving oxygenation and reducing the risk of complications.
- The patient should place their lips tightly around the mouthpiece to form a good seal and inhale through their mouth to achieve the maximum volume.
- Slow inhalation prevents the airways from collapsing and helps the patient sustain lung inflation for a longer duration.
Why Other Options Are Incorrect:
- Option A: Performing incentive spirometry only once per shift is insufficient; typically, patients are advised to use it 10 times per hour while awake for optimal lung expansion.
- Option B: The patient should inhale deeply rather than exhaling quickly, as exhalation does not promote lung inflation.
- Option D: Exhalation through the spirometer is incorrect; the focus is on inhalation to achieve the desired outcome of lung expansion.
