What is the main advantage of using disposable gloves in medication administration?

The main advantage of using disposable gloves in medication administration is that they provide a barrier for contamination. Wearing gloves helps to prevent the transfer of pathogens, bodily fluids, and contaminants from the skin to the medication or the patient's body. This barrier is crucial in maintaining aseptic conditions and protecting both the healthcare provider and the patient during the medication administration process.

While the use of gloves may contribute to the prevention of allergic reactions for individuals who have specific sensitivities (which could be a factor in option A), this is not the primary purpose of wearing gloves. Ensuring medication efficacy (option B) is related to how the medication is stored, prepared, and administered, rather than the use of gloves. Lastly, while gloves may aid in certain tasks like pill crushing, this is not their main advantage and does not encompass the primary role of gloves in infection control.
