For cystic fibrosis, inhaled medications include all the following EXCEPT?

  1. Hypertonic Saline

  2. Dornase alfa

  3. Inhaled antibiotics

  4. Oral rehydration solutions

The correct answer is: Oral rehydration solutions

While inhaled medications are a common form of treatment for cystic fibrosis, oral rehydration solutions do not have a therapeutic effect when inhaled and therefore are not used in treatment. Hypertonic Saline is used to help thin mucus in the airways, Dornase alfa is used to break down thick and sticky mucus, and inhaled antibiotics are used to prevent and treat lung infections in people with cystic fibrosis. Therefore, the other options are incorrect as they are all used as inhaled medications for cystic fibrosis while oral rehydration solutions are not.
