43. A nurse is reinforcing teaching about use of a metered-dose inhaler (MDI) with a client who has a new diagnosis of asthma. Identify the sequence the client should follow. (Move the steps into the box on the right, placing them in the selected order of performance. Use all steps.)

C. Persistent shortness of breath after using an inhaler could indicate an inadequate response to treatment or worsening asthma exacerbation. The nurse should therefore see this patient first.
A. In COPD patients pulse oximetry oxygen saturations of more than 90% are acceptable. In the treatment of exacerbations of chronic obstructive pulmonary disease (COPD), oxygen should be titrated to achieve a target oxygen saturation range of 88-92%. This results in a greater than twofold reduction in mortality, compared with the routine administration of high-concentration oxygen therapy.
B. Administering antibiotics can be prioritized, but it may not require immediate attention compared to addressing acute respiratory distress or hypoxemia.
D. Collecting a sputum specimen for laboratory analysis is important for diagnosing and managing respiratory infections, but it may not be as time-sensitive as addressing acute respiratory distress or hypoxemia.

B. The inability to clear the airway is a critical issue. This patient has a weak, congested-sounding cough and moist crackles, indicating that secretions are present and not being effectively cleared. This can lead to airway obstruction, decreased oxygenation, and further respiratory complications. Clearing the airway is a top priority to ensure the patient can breathe properly and prevent further deterioration.
A. Difficulty breathing (dyspnea) is a serious concern as it can indicate respiratory distress or failure. However, it is often a symptom rather than a primary issue, and its underlying causes (such as an inability to clear the airway or inadequate oxygen levels) must be addressed first.
C. Confusion can result from high fever, infection, or hypoxia. While it is important to address the fever and its underlying cause, confusion itself is usually a secondary issue. Addressing the primary respiratory issues will often improve the patient's mental status as well.
D. Hypoxia can result from severe pneumonia, and resolving it involves ensuring the patient has a clear airway and adequate ventilation. Measuring and correcting oxygen levels (e.g., with supplemental oxygen) is crucial, but the underlying cause (such as airway obstruction) must also be managed.
