Which of the following actions should a medical assistant take when performing a hearing and vision screening?

A. Wrapping hinged instruments in the open, unlocked position: Hinged instruments should be wrapped in the open, unlocked position to ensure that steam can penetrate all surfaces for effective sterilization.
B. Allowing the temperature of the autoclave to reach 200° F before timing: The autoclave should reach the required temperature (typically 250°F or 121°C) for the appropriate amount of time for sterilization, not 200°F.
C. Using a ballpoint pen to label contents: It is not advisable to use a ballpoint pen for labeling sterilized items because ink might not withstand the autoclave's high temperatures. Permanent markers or labels that can endure high temperatures should be used.
D. Stacking wrapped packages tightly into the autoclave: Items should be arranged in a way that allows steam to circulate freely, so tightly stacking packages can hinder proper sterilization.

A. Allow the solution to flow from the inner to the outer canthus: This technique helps to flush out debris and contaminants while avoiding the spread of the solution into the unaffected eye.
B. Fill the syringe with 10 mL of the irrigating solution. The volume of the irrigating solution may vary, but 10 mL is not a standard quantity; the key is ensuring adequate flushing.
C. Don powdered gloves: Powdered gloves can cause irritation; non-powdered gloves are recommended for eye irrigation.
D. Direct the irrigation solution toward the cornea: The solution should not be directed toward the cornea to avoid damage; it should flow gently across the eye.
