Final answer:
The next step after opening a sterile solution is to hold the bottle outside the sterile field, label facing the palm, and pour from a height of 4 to 6 inches to avoid contamination.
Step-by-step explanation:
The correct next step after opening a bottle of sterile solution to add to a sterile field is: Option D. Hold the bottle outside the edge of the sterile field with the label side facing the palm of the hand and prepare to pour from a height of 4 to 6 in (10 to 15 cm). This technique helps to minimize the risk of contamination as the elevated height allows for any potential airborne contaminants to dissipate and prevents the label from being contaminated by the liquid, which would happen if the bottle were held with the label facing down.
