Which of the following statements accurately reflects the relationship between obesity and surgical risk?

A. Pursed-lip breathing does not require a specific body position, but it is often more comfortable and effective when the patient is in a semi-Fowler’s position (elevated head of the bed) or sitting upright. Being flat on the back might actually make breathing more difficult for some patients with COPD.
B. The technique involves inhaling slowly through the nose and exhaling through pursed lips, which creates a slight resistance during expiration. This helps to keep the airways open longer, reduce airway collapse, and improve oxygen exchange. Proper inhalation and exhalation technique are key components of effective pursed-lip breathing.
C. In pursed-lip breathing, expiration should be longer than inspiration. The recommended pattern is to inhale slowly through the nose for about 2 counts and then exhale slowly through pursed lips for about 4 counts. The extended expiration phase helps to remove trapped air from the lungs and improves overall ventilation.
D. Coughing forcefully is not a part of pursed-lip breathing. Pursed-lip breathing focuses on controlled breathing to improve airflow and ease breathing. Coughing can be done separately if needed, but it is not a component of the pursed-lip breathing technique.

A. While asking appropriate questions demonstrates that the partner is engaged and seeking understanding, it alone does not indicate that they are ready to perform the procedure independently.

B. Being able to verbalize all steps in the procedure shows that the partner has knowledge and understanding of the process. However, verbalizing alone does not confirm that they can perform the procedure accurately and safely. Practical skills and hands-on competence are crucial for readiness.
C. Attending a class provides important theoretical knowledge and information about tracheostomy care. However, attending a class by itself does not guarantee that the partner has developed the necessary skills to perform suctioning independently.
D. The ability to perform the procedure independently indicates that the partner has acquired the necessary skills and confidence to carry out suctioning safely and effectively. It shows practical proficiency, which is essential for readiness for discharge. The partner’s ability to perform suctioning without assistance demonstrates that they can handle the procedure in real-life situations.
