Final answer:
Option c) Bronchodilators are the solution to make breathing easier for a patient with a tumor in the respiratory tract because they relax the muscles around the airways and expand them.
Step-by-step explanation:
If a patient has a tumor in her respiratory tract, an effective solution to make breathing easier for them is C) Bronchodilators.
Bronchodilators work by relaxing the muscles around the airways, thereby opening them wider which helps to re-expand constricted air passages and make breathing easier. This is particularly useful in conditions like asthma where airways can become constricted, as well as potentially helpful when a patient has a tumor that could be causing obstruction in the respiratory tract. While diuretics are for reducing fluid retention, antipyretics are for reducing fever, and antibiotics are for treating bacterial infections, these options would not typically aid in easing breathing difficulties associated with a respiratory tract tumor.
