Which items would be categorized as contaminated sharps?

Contaminated sharps refer to items that can cause punctures or cuts and are likely to be contaminated with blood or other potentially infectious materials. This definition is crucial in healthcare settings to ensure the safety of both personnel and patients.

In this context, needles and scalpels that have come into contact with blood or other bodily fluids fall squarely into the category of contaminated sharps. These items pose a significant risk of transmitting infections and must be disposed of in designated containers that are puncture-resistant and labeled for biohazardous waste.

The other options do not meet the criteria for contaminated sharps. Clean scalpels and gloves suggest no exposure to infectious substances, broken glass and unopened needles do not represent an immediate biohazard, and cleansed tools and instruments imply effective sterilization and safety from contamination. Thus, the choice of contaminated needles and scalpels aligns perfectly with the definition and criteria for contaminated sharps.
