A nurse is caring for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. Which of the following actions should the nurse take?

Answer: D. Cheyne-Stokes respirations

Rationale:

A) Stridor: Stridor is a high-pitched, wheezing sound resulting from disrupted airflow in the upper airway. It is not characterized by alternating periods of hyperventilation and apnea, making this choice incorrect.

B) Kussmaul respirations: Kussmaul respirations are deep, labored breaths typically associated with metabolic acidosis, such as diabetic ketoacidosis. These respirations do not exhibit alternating periods of hyperventilation and apnea, so this option is not applicable.

C) Apneustic respirations: Apneustic respirations are characterized by prolonged inhalation followed by a prolonged pause before exhalation. This pattern does not align with the alternating hyperventilation and apnea described, making it an incorrect choice.

D) Cheyne-Stokes respirations: Cheyne-Stokes respirations are characterized by a cyclical pattern of increasing depth and rate of breathing followed by a gradual decrease in depth and a period of apnea. This description matches the client's breathing pattern of alternating hyperventilation and apnea, making this the correct answer.

Administering a short-acting beta2-agonist (SABA), such as albuterol, is the priority intervention for the nurse to take, as it provides rapid bronchodilation and relieves bronchospasm, which are the main features of status asthmaticus. Status asthmaticus is a severe and life-threatening asthma attack that does not respond to usual treatment and requires immediate medical attention.

a) Determining the cause of the acute exacerbation is important, but not the priority intervention for the nurse to take. The cause may be an allergen, infection, stress, or exercise, but it does not affect the immediate management of status asthmaticus. The nurse should focus on restoring airway patency and oxygenation first, and then identify and avoid triggers later.
b) Obtaining a peak flow reading is important, but not the priority intervention for the nurse to take. The peak flow reading measures the maximum expiratory flow rate and indicates the degree of airway obstruction. However, it may not be feasible or accurate in a child who is experiencing status asthmaticus, as they may be too dyspneic or agitated to perform the test. The nurse should rely on other signs of respiratory distress, such as wheezes, retractions, cyanosis, or pulse oximetry.
c) Administering an inhaled glucocorticoid is important, but not the priority intervention for the nurse to take. Glucocorticoids, such as fluticasone or budesonide, reduce inflammation and mucus production in the airways, but they have a delayed onset of action and are not effective for acute asthma attacks. They are used for long-term control and prevention of asthma symptoms.
