A nurse is teaching a client who is obese and has obstructive sleep apnea how to decrease the number of nightly apneic episodes. Which of the following client statements indicates an understanding of the teaching?

These findings are expected to be assessed in a client who has emphysema, which is a type of chronic obstructive pulmonary disease (COPD) characterized by destruction and enlargement of alveoli, loss of elastic recoil, and air trapping. These changes impair gas exchange and oxygenation, leading to chronic hypoxia and hypercapnia.

a) Dyspnea, or difficulty breathing, is a common symptom of emphysema, as the client has reduced lung capacity and increased work of breathing. Dyspnea may be worse with exertion, stress, or infection, and may cause anxiety and fatigue. The nurse should monitor the client's respiratory rate, rhythm, depth, and effort, and provide oxygen therapy as prescribed.
b) Barrel chest, or increased anteroposterior diameter of the chest, is a physical sign of emphysema, as the client has chronic air trapping and hyperinflation of the lungs. Barrel chest may also cause kyphosis, or curvature of the spine, and reduced chest wall movement. The nurse should measure the client's chest circumference and observe for any deformities or asymmetry.
d) Clubbing of the fingers, or enlargement and rounding of the nail beds, is a late sign of emphysema, as the client has chronic hypoxia and tissue ischemia. Clubbing may also affect the toes and ears, and may indicate pulmonary or cardiac disease. The nurse should inspect the client's nails for shape, color, angle, and capillary refill.

c) Deep respirations are not expected to be assessed in a client who has emphysema, as the client has shallow and rapid breathing due to air trapping and reduced lung compliance. Deep respirations may indicate other conditions, such as metabolic acidosis or anxiety. The nurse should assess the client's arterial blood gas levels and provide reassurance and relaxation techniques as needed.
e) Bradycardia, or slow heart rate, is not expected to be assessed in a client who has emphysema, as the client has tachycardia or normal heart rate due to hypoxia and increased sympathetic stimulation. Bradycardia may indicate other conditions, such as medication side effects, vagal stimulation, or heart block. The nurse should monitor the client's pulse rate, rhythm, quality, and electrocardiogram as indicated.

A. Dyspnea:
Dyspnea (shortness of breath) is a common symptom in emphysema due to the destruction of alveolar walls and the resulting reduction in surface area for gas exchange. As the disease progresses, the patient experiences increasing difficulty in breathing, especially during exertion or when the disease becomes more severe.

B. Barrel chest:
A barrel chest is often seen in emphysema, as it results from hyperinflation of the lungs. The increased air trapping due to damaged alveoli causes the chest to expand and become rounded, leading to the characteristic "barrel chest" appearance. This happens because the lungs are constantly overinflated, and the chest wall becomes rigid and rounded as a result.

D. Clubbing of the fingers:
Clubbing of the fingers can occur in chronic respiratory conditions like emphysema due to prolonged hypoxia (low oxygen levels in the blood). This is a compensatory mechanism that involves changes in the nails and fingers. The tips of the fingers become rounded and bulbous over time, and this is commonly associated with long-standing pulmonary diseases.
