Answer to Question 1

ANS: A
All of the options are signs of aging; however, the glomerular filtration rate affects metabolism and medication clearance. The buildup of medication can cause toxicity in older patients.

Answer to Question 2

ANS: A
A 27-gauge, 3/8-inch needle is used for intradermal injections such as a tuberculin test, which should be inserted at a 15-degree angle, just under the dermis of the skin. Placing the needle at 45 degrees, 90 degrees, or 180 degrees will place the medication too deep.
