Question

Which statement is true regarding insulin syringes?

1 They are 3 to 5 mL in size.
2 The needles each have two parts, the hub and shaft.
3 They are designed for use with U-100 strength insulin.
4 They are marked in 0.01 (hundredths) for doses less than 1 mL.

Answer 1

The correct answer is that insulin syringes are designed for use with U-100 strength insulin. They are not 3 to 5 mL in size and are marked in one-unit increments for U-100 insulin, and while needles have a hub and shaft, this is not unique to insulin syringes.

Step-by-step explanation:

The insulin syringes are specifically designed for use with insulin, which is typically standardized at U-100 strength. This means that the syringes are calibrated for insulin that has 100 units of insulin per milliliter (mL) of liquid. Thus, the correct statement regarding insulin syringes is that they are designed for use with U-100 strength insulin. It is also important to know that syringes for insulin are not typically 3 to 5 mL in size; they are usually much smaller because insulin doses are generally quite small. The scales on insulin syringes are indeed marked for precise measurements to ensure the correct dose is delivered but are often marked in increments of one unit for U-100 insulin, not necessarily in 0.01 increments. As for the needle components, the needle does consist of parts including the hub (which attaches to the syringe) and shaft (the length of the needle), but this is not specific to insulin syringes and is true for most types of needles.
