Question

which of the following sizes of syringe should a pharmacy technician use to draw 4.2 ml of potassium chloride?
○ 1 ml
○ 5 ml
○ 10 ml
○ 3 ml

Explanation:

To determine the appropriate syringe size, we need a syringe that can hold at least 4.2 mL. A 1 mL syringe is too small (1 < 4.2), a 3 mL syringe is also too small (3 < 4.2), a 10 mL syringe can hold it but is larger than needed, while a 5 mL syringe can hold 4.2 mL (5 ≥ 4.2) and is the smallest among those that can accommodate the volume.

Answer:

B. 5 mL
