Answer to Question 1

ANS: A
The fluids of the respiratory tract originate from specialized mucous glands (goblet cells) and serous glands that line the respiratory tract. The goblet cells produce gelatinous mucus that forms a thin layer over the interior surfaces of the trachea, bronchi, and bronchioles. Lymph does not make up fluid in the respiratory tract. The beta cells in the islets of Langerhans are located in the pancreas. Cells that produce aqueous humor are located in the interior of the eye.

Answer to Question 2

ANS: B
Dry mouth is usually mild and tends to resolve with continued therapy. Anxiety, tachycardia, and urine retention are not common adverse effects.
