Answer to Question 1

ANS: A
A 27-gauge, -inch needle is used for intradermal injections such as a tuberculin test, which should be inserted at a 5- to 15-degree angle, just under the dermis of the skin. Placing the needle at 30 degrees, 45 degrees, or 90 degrees will place the medication too deep.

Answer to Question 2

ANS: C
The purpose of aspiration is to ensure that the needle is in the muscle and not in the vascular system. Blood return upon aspiration indicates improper placement, and the injection should not be given. While a patient can aspirate fluid and food into the lungs, this is not related to the reason for why a nurse pulls back the syringe plunger after inserting the needle (aspirates) before injecting the medication. Reducing discomfort and prolonging absorption time are not reasons for aspirating medications.
