1/4 inch
1/2 inch
1 inch
1 1/2 inches
The Correct Answer is C
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.
