In a patient with cystic fibrosis presenting with rhonchi and abdominal pain, what should you do?

In a patient with cystic fibrosis who presents with rhonchi and abdominal pain, administering oxygen by nasal cannula is a crucial step in management. Cystic fibrosis affects the respiratory system by causing the production of thick, sticky mucus, which can lead to airway obstruction and respiratory distress. Rhonchi typically indicate that there are secretions in the airways, which might compromise adequate gas exchange and lead to hypoxia.

By providing supplemental oxygen, you can help improve the oxygen saturation in the blood, thus addressing hypoxemia that may occur due to the patient's respiratory condition. Using a nasal cannula allows for continuous oxygen delivery while enabling the patient to maintain some level of oral intake and communication.

While other options like administering OTC antidiarrheal or antiemetic medications might seem relevant due to accompanying abdominal pain, they do not directly address the immediate respiratory issues that are critical in a cystic fibrosis patient presenting with such symptoms. Furthermore, initial management of airway and ventilation is paramount before considering other symptomatic treatments. The choice to use a nasal cannula also enables a more manageable and less intrusive form of oxygen delivery compared to a non-rebreather mask, which might not be indicated at this stage if the patient's need for oxygen is not immediate and
