A nurse is providing dietary teaching for a client who has chronic obstructive pulmonary disease. Which of the following instructions should the nurse include?

Answer: A

Rationale:

A) Administering a nebulized beta-adrenergic:

In the case of an acute asthma exacerbation, administering a nebulized beta-adrenergic agonist (such as albuterol) is the highest priority. These medications act quickly to relax bronchial smooth muscle, dilate airways, and improve airflow. This intervention directly addresses the underlying bronchospasm and helps to alleviate the acute symptoms of asthma.

B) Providing immediate rest for the client:

While rest is important in managing an acute asthma exacerbation, it is not the immediate priority. Addressing the airway obstruction with appropriate medications is crucial for stabilizing the client's condition before focusing on comfort measures such as rest.

C) Positioning the client in high-Fowler's:

Positioning the client in a high-Fowler's position can help improve lung expansion and facilitate breathing. However, this action is secondary to administering medication that can relieve the acute symptoms of bronchoconstriction. The medication should be administered first to rapidly address the exacerbation.

D) Initiating oxygen therapy:

Oxygen therapy might be necessary if the client shows signs of hypoxemia or severe respiratory distress. However, the immediate priority is to address the bronchospasm with a nebulized beta-adrenergic agonist to improve airflow. Once the acute bronchospasm is managed, oxygen therapy can be implemented if needed to support oxygen saturation.

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.
