Answer to Question 1

Ans: A, D
Feedback:
Benzonatate and potassium iodide are expectorants, which increase the production of secretions, thus making the secretions less viscous. Guaifenesin, codeine, and dextromethorphan are antitussives, which suppress cough.

Feedback:
A client's antitussive teaching plan should include the following instructions: do not exceed recommended dose; avoid respiratory irritants; drink plenty of fluids if not contraindicated; swallow oral capsules whole; avoid drinking fluids for 30 minutes after taking a lozenge; do not use alcohol or other CNS depressants while being treated with antitussives; and contact the physician if cough is not relieved or becomes worse or is accompanied by chills, fever, chest pain, or sputum production.
