Answer to Question 1

ANS: B
Sodium chloride acts by hydrating mucus. This will decrease the viscosity of mucous plugs, which makes it easier for patients to cough up the dry hardened plugs blocking the bronchial tubes. Sodium chloride is not given to increase serum sodium iodide levels. Sodium does not reduce metabolic needs of the body or bronchial irritation.

Answer to Question 2

ANS: C
Guaifenesin is used for symptomatic relief of conditions characterized by a dry, nonproductive cough such as the common cold, bronchitis, laryngitis, pharyngitis, and sinusitis. Guaifenesin is also used to remove mucous plugs from the respiratory tract. Dextromethorphan is an antitussive. Diphenhydramine is an anticholinergic agent with antihistaminic and antitussive properties. Codeine is an antitussive.
