The nurse is evaluating the knowledge of a patient recently diagnosed with type 1 DM. Which statement by the patient indicates a need for additional information?

C. Pursed lip breathing is a technique that can help patients with acute dyspnea by improving ventilation, prolonging exhalation, and reducing the work of breathing. It helps to keep the airways open longer and makes it easier to get rid of excess carbon dioxide, which can provide quick relief from acute shortness of breath.
A. Teaching the patient about using accessory muscles for breathing can be beneficial in managing chronic respiratory issues, but it is not an immediate intervention.
B. Understanding the cause of dyspnea is important for treatment planning but it is not the first action to take when the patient is experiencing acute shortness of breath.
D. The Sims position, where the patient lies on their side with the lower arm behind the back and the upper leg flexed, is not typically used for relieving acute respiratory distress.

A. Diminished breath sounds can occur in emphysema due to decreased air movement through damaged and enlarged air sacs (alveoli). The destruction of alveolar walls reduces the surface area available for gas exchange and can result in decreased breath sounds.
C. Patients with emphysema may use accessory muscles, such as neck and shoulder muscles, to assist with breathing during periods of respiratory distress. These muscles are recruited to help increase the size of the thoracic cavity and improve airflow.
E. A barrel-shaped chest is a common physical finding in patients with emphysema. It results from hyperinflation of the lungs and is characterized by an increased anterior-posterior diameter of the chest. This change in chest shape is due to air trapping in the lungs, leading to overinflation of the alveoli and increased residual volume.
B. Ruddy skin color, which refers to a reddish or flushed complexion, is not typically associated with emphysema. Instead, patients with emphysema may exhibit cyanosis (bluish discoloration of the skin) during periods of hypoxemia (low oxygen levels).
D. Excess mucus production (mucus hypersecretion) is a characteristic feature of chronic bronchitis, which is often present alongside emphysema in chronic obstructive pulmonary disease (COPD) but it is not typically a primary feature of emphysema itself.
