Answer to Question 1

Ans: C
Intradermal injection routes are commonly used for tuberculin tests and allergy testing because they are administered between the layers of the skin. A subcutaneous injection is not suitable because it is administered more deeply than an intradermal injection; whereas, an intramuscular injection is administered in one muscle or muscle group. Intravenous injection is also not suitable because it is instilled into veins.

Answer to Question 2

Ans: D
When administering an intradermal injection, the nurse should hold the syringe almost parallel to the skin at a 10-degree angle with the bevel pointing upward. This facilitates delivering the medication between the layers of the skin and advances the needle to the desired depth. A nurse administers a subcutaneous injection at a 45-degree angle or a 90-degree angle to reach the subcutaneous level of tissue, depending on the length of the needle. The nurse will not be able to insert the injection if it is held at a 180-degree angle.
