B.

Isopropyl alcohol

C.

Bleach

D.

lodine compounds

Answer and Explanation

The Correct Answer is C

A. Glutaraldehyde: Glutaraldehyde is used for high-level disinfection of medical equipment, not for cleaning blood spills.

 

B. Isopropyl alcohol: While isopropyl alcohol is used for disinfection, it is not the preferred choice for blood spills due to its lower efficacy against certain pathogens.

 

C. Bleach: A bleach solution is effective for disinfecting surfaces contaminated with blood, as it is effective against a broad range of pathogens, including bloodborne viruses.

 

D. Iodine compounds: Iodine is used for antiseptic purposes on skin but is not ideal for disinfecting blood spills on surfaces.

Correct Answer is C

Explanation

A. 1/4 inch: A 1/4 inch border is too small to be considered a standard contaminated area. The correct border size is larger.

B. 1/2 inch: A 1/2 inch border is also not standard; the correct contaminated border is larger.

C. 1 inch: The standard for sterile fields is to consider a 1-inch border around the edge of the sterile field as contaminated. This helps to prevent inadvertent contamination of sterile items.

D. 1 1/2 inches: A 1 1/2 inch border is unnecessarily large and exceeds the standard 1-inch margin considered contaminated.
