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.
