A nurse in an urgent care center is caring for a client who is having an acute asthma exacerbation. Which of the following actions is the nurse's highest priority?

Intercostal retractions, or the inward movement of the chest wall between the ribs, are a sign of respiratory distress and hypoxia. They indicate increased work of breathing and reduced lung expansion, which are common in clients who have postoperative atelectasis. Atelectasis is a collapse of alveoli in a part of the lung, which impairs gas exchange and oxygenation.

a) Lethargy, or a state of reduced mental alertness and energy, is not a typical manifestation of hypoxia. It can be caused by other factors, such as pain, medication, infection, or electrolyte imbalance. Hypoxia usually causes restlessness, anxiety, or confusion.
b) Bradycardia, or a slow heart rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, vagal stimulation, or heart block. Hypoxia usually causes tachycardia, or a fast heart rate, as the body tries to compensate for the low oxygen level.
d) Bradypnea, or a slow respiratory rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, brain injury, or metabolic alkalosis. Hypoxia usually causes tachypnea, or a fast respiratory rate, as the body tries to increase oxygen intake and carbon dioxide elimination.

A. Administration of a prescribed bronchodilator is typically recommended approximately 30 minutes prior to meals rather than 1 hour. This pharmacological timing helps reduce dyspnea and facilitates easier deglutition and mastication by improving airflow. Using it too early may result in the peak therapeutic effect tapering off before the client finishes the meal.

B. Consuming 3 large meals each day is contraindicated for clients with chronic obstructive pulmonary disease because a distended stomach can exert upward pressure on the diaphragm. This abdominal crowding significantly increases the work of breathing and leads to early satiety or respiratory distress. Clients are instead encouraged to eat 5 to 6 small, frequent, nutrient-dense meals.

C. The nurse should instruct the client to limit water or fluid intake during the actual mealtime to prevent premature gastric distention. Early fullness from fluids reduces the client’s ability to consume essential solid nutrients and calories required to support the increased metabolic demands of labored breathing. Fluids should be consumed between meals to maintain adequate hydration and thin secretions.

D. Reducing protein intake is inappropriate because these clients require high-protein and high-calorie diets to prevent muscle wasting and support the respiratory muscles. The metabolic cost of breathing in chronic obstructive pulmonary disease is significantly elevated, often leading to a state of malnutrition or cachexia. Protein is vital for tissue repair and maintaining the functional integrity of the diaphragm.
