Final answer:
In inhalation therapy, drugs are delivered directly to the respiratory system and quickly absorbed into the bloodstream, providing fast relief. Patient cooperation is required for proper use of inhalers or nebulizers. Inhalation therapy is comfortable for patients and allows potent drugs to be given in small amounts.
Step-by-step explanation:
An advantage of inhalation therapy is the rapid onset of action, meaning that the drugs are delivered directly to the respiratory system and quickly absorbed into the bloodstream, providing fast relief. Another advantage is that potent drugs may be given in small amounts because the lungs have a large surface area for drug absorption. However, inhalation therapy does require patient cooperation as they need to properly use the inhaler or nebulizer to ensure the medication reaches the lungs. Inhalation therapy is also considered a means of delivery comfortable for the patient, as it does not involve needles or invasive procedures. Therefore, the correct answer is B. does not require patient cooperation is NOT an advantage of inhalation therapy.
