Rationale: Diphenhydramine (Benadryl) has several uses, including antihistamine, antitussive, antidyskinetic, and sedative-hypnotic. Because the medication causes drowsiness, the client should avoid use of alcohol or central nervous system (CNS) depressants, operating a car, or engaging in other activities requiring mental acuity during use. It should be taken with food or milk to decrease gastrointestinal upset, and oral rinses, sugarless gum, or hard candy may be used to minimize dry mouth.
Answer to Question 2

Rationale: An infiltrated IV is one that has dislodged from the vein and is lying in subcutaneous tissue. The pallor, coolness, and swelling are the result of IV fluid being deposited in the subcu-taneous tissue. When the pressure in the tissues exceeds the pressure in the tubing, the flow of the IV solution will stop. The corrective action is to clamp the IV tubing, remove the catheter, and prepare to start a new IV line. The other three options are likely to be accompanied by warmth at the site, not coolness.
