The nurse is adminstering influenza vaccine injections in the fu clinic. The vaccine dose is contained in 05 mL and is given IM to aduits into the dolloid muscle The best choice of syringe and needio for this dose of vaccine is \( 1 \mathrm{~mL} 27 \mathrm{G} 38^{\circ} \) \( 1 \mathrm{~mL} 25 \mathrm{G}^{5 / 8^{\circ}} \) \( 3 \mathrm{~mL} 2361^{\circ} \) \( 3 \mathrm{~mL} 19 \mathrm{G} 11 / 2^{2} \) Nand

1. The influenza vaccine dose is \(0.5\) mL. For such a small volume, it is best to use a \(1\) mL syringe so that the measurement is accurate and there is less dead space. 2. Intramuscular (IM) injections in the deltoid muscle for adults typically use a needle that is long enough to reach the muscle but not excessively long. For most adults, a needle length of about \(5/8\) inch to \(1\) inch is recommended. A \(5/8\) inch needle is often used for adults with average body mass. 3. The gauge of the needle should be thin enough to minimize discomfort but sturdy enough to deliver the vaccine into the muscle. A \(25\) gauge needle is commonly used for IM injections. 4. Among the options provided, the choice with a \(1\) mL syringe, \(25\) gauge, and a \(5/8\) inch needle best meets the criteria. Thus, the best choice is: \(1 \mathrm{~mL}\ 25 \mathrm{G}\ 5/8^{\prime\prime}\)
