Answer to Question 1

ANS: D
Intradermal injections should be given with a 25- to 27-gauge, 3/8- to 5/8-long needle. The needle should be inserted at a 10- to 15-degree angle. The area should not be massaged. The nurse measures the area of induration, not erythema.

Answer to Question 2

ANS: A
Patients giving subcutaneous medication should be taught not to aspirate after inserting the needle. They should not apply pressure. The needle should be inserted at a 45- to 90-degree angle. Absorption is slower with this route than with the intramuscular and intravenous routes.
