The health-care provider has written an order to administer a PPD to Thomas Staccotti. As you gather your equipment and supplies, you know that you will need which of the following size needles and syringe?
- A. 18 g ? 1 in
- B. 20 g ? 7/8 in
- C. 25 g ? 7/8 in
- D. 23 g ? 1 in
Correct Answer: C
Rationale: For a PPD (purified protein derivative) test, which is an intradermal injection, a small gauge needle (25?27 gauge) with a short length (3/8 to 5/8 inch) is required to ensure the medication is injected just below the skin surface. A 25 g ? 7/8 in needle is appropriate.

What gauge and length needle would you select to administer an IM injection of a viscous medication, such as gamma globulin, in the ventrogluteal site of a 29-year-old male body builder who is in good health and weighs 203 pounds?
- A. 25 g ? 1.5 in
- B. 20 g ? 1/2 in
- C. 21 g ? 7/8 in
- D. 24 g ? 1 in
- E. 18 g ? 1½ in
Correct Answer: E
Rationale: For a viscous medication like gamma globulin in a muscular adult, a larger gauge (18?21 g) and longer needle (1?1½ in) are needed to penetrate the muscle deeply. An 18 g ? 1½ in needle is appropriate for the ventrogluteal site in a muscular male.
