A. 3 mL syringe: A 3 mL syringe is ideal for administering a 1.5 mL IV push because it allows accurate measurement and precise control of small volumes. The fine gradations on a 3 mL syringe reduce the risk of dosing errors compared to larger-capacity syringes. B. 5 mL syringe: A 5 mL syringe could hold 1.5 mL, but the larger size makes precise measurement more difficult. Small-volume IV medications require a syringe that allows for accurate dosing to prevent under- or over-administration. C. 1 mL syringe: A 1 mL syringe cannot hold 1.5 mL, making it inappropriate for this dose. Using it would require multiple draws, increasing the risk of error and contamination. D. 10 mL syringe: A 10 mL syringe is too large for accurately measuring 1.5 mL. Using a syringe much larger than the dose reduces precision and control during IV push administration.
