Explanation:

Question 1 (All of the following are prescribed for influenza, except ______.)

Influenza is a viral infection. Antibiotics are used to treat bacterial infections, not viral ones like influenza. Decongestants, salt - water gargles, and cough medicines can be used to relieve influenza symptoms.

In the lungs, gas exchange (oxygen and carbon dioxide exchange between blood and air) occurs in the alveoli. Bronchioles are for air conduction, alveolar ducts are part of the airway leading to alveoli, and terminal sacs are not the main site of gas exchange.

Nasal hairs (vibrissae) in the nose act as a filter to trap large airborne particles. External nares are the nostrils, the soft palate is related to swallowing and speech, and nasal sinuses are for air humidification and resonance, not filtering large particles.

Answer:

B. antibiotics

Question 5 (The actual sites of gas exchange within the lungs are the ______.)
