A nurse enters a client's room to administer medication and finds the client lying in bed disoriented with labored and fast respirations. Which of the following actions should the nurse take first?

A. Obtain a sputum culture: While a sputum culture may help identify infection, it is not the immediate priority when a client is experiencing labored and rapid respirations. Immediate interventions to improve airway and oxygenation take precedence. B. Prepare the client for endotracheal suctioning: Suctioning may be necessary if secretions are obstructing the airway, but the first action should be to optimize the client’s position to facilitate spontaneous breathing before invasive procedures. C. Elevate the head of the bed: Elevating the head of the bed improves lung expansion, enhances oxygenation, and reduces work of breathing. Positioning is the first and most immediate intervention in a client with respiratory distress according to the airway, breathing, circulation (ABC) prioritization. D. Request a chest x-ray: A chest x-ray can help diagnose underlying causes of respiratory distress, but it does not provide immediate relief of hypoxia or improve ventilation. Immediate positioning to optimize breathing is the priority.
