Question

If a patient is to have an arthrodesis and injection of corticosteroid into the right knee and the ambulatory care nurse is setting up equipment, the correct needle gauge syringe sizes are:

A. 18G needle and 10-20ml syringe
B. 20G needle and 20ml syringe
C. 16G needle and 10-20ml syringe
D. 19g needle and 50ml syringe

Answer 1

For an arthrodesis and corticosteroid injection into the knee, the typical needle and syringe sizes are an 18G needle and a 10-20ml syringe, to accommodate the volume of medication and allow the viscous corticosteroid to be injected effectively.

Step-by-step explanation:

If a patient is scheduled for an arthrodesis and an injection of corticosteroid into the right knee, the choice of syringe and needle gauge size can impact the effectiveness and safety of the procedure. Typically, for joint injections such as a corticosteroid administration, a larger syringe is used because it can accommodate the volume of medication and allows for easier handling of the viscous fluid.

For the injection of corticosteroids into the knee, a usual choice would be an 18G needle and a 10-20ml syringe. This needle's gauge is sufficient enough to allow the thick corticosteroid medication to pass through smoothly, while the syringe size enables the health care practitioner to administer a volume often required for knee joints. Therefore, the correct equipment setup would be option A: 18G needle and 10-20ml syringe.
