Final answer:
A medical assistant should use a winged infusion set for venipuncture, not for intramuscular injections. Insulin injections decrease blood glucose levels, and oral antimicrobials are convenient for home treatment of a systemic infection.
Step-by-step explanation:
A medical assistant should not use a winged infusion set for an intramuscular injection. Winged infusion sets, also known as butterfly needles, are typically used for venipuncture to access a vein for drawing blood or administering fluids or medications intravenously. Intramuscular injections are administered directly into the muscle using a needle and syringe appropriate for the depth and volume of medication being injected.
The correct use of insulin injections, as described in the reference information, is to decrease blood glucose levels after consuming a large or high-glucose meal. Insulin facilitates the transport and storage of glucose within the body, helping to reduce blood sugar levels.
For dehydrated patients requiring replenishment of fluids, intravenous administration of fluids is appropriate. If a systemic infection requires treatment at home, an oral antimicrobial route of administration is usually the most convenient and appropriate.
