Which practice helps prevent contamination when administering ophthalmic drops?

• A. Touch the dropper to the eye
• B. Do not touch the dropper to the eye
• C. Wipe the bottle with a cloth before use
• D. Draw from the bottle with the mouth to prevent spills

Answer: (B)

Preventing contamination hinges on keeping the dropper tip sterile and away from any surface that could carry bacteria. Not touching the dropper tip to the eye stops microbes from the eye, skin, or environment from getting into the bottle and contaminating subsequent doses. This simple action helps preserve the solution’s sterility for future use. Why the other options aren’t safe: touching the dropper to the eye can transfer bacteria from the eye or skin back into the bottle, compromising sterility. Wiping the bottle with a cloth can shed fibers and introduce microbes or debris into the dropper opening, increasing contamination risk. Drawing from the bottle with the mouth is unsafe and introduces oral bacteria, plus it’s a choking hazard and generally unsanitary.
