Final answer:
Medical objects that must go in a sharps container include used needles, used glass microscope slides, and IV catheter stylets due to their potential to cause puncture wounds and carry biohazards.
Step-by-step explanation:
The items that must go in a sharps container are those that can pose a risk of puncture and are potentially contaminated with pathogens. The correct answer to the question of which medical objects must go in a sharps container is option C) Used needle, used glass microscope slide, IV catheter stylet. These items are considered to be biohazards because they could harbor contaminants such as blood that may be infected with disease-causing organisms.
Sharps containers are typically used for the disposal of medical needles, blades (such as scalpel blades), and other items that could cause puncture wounds, and thus have a potential risk of spreading infection. This is to ensure both healthcare worker safety and patient safety by preventing needle-stick injuries and the spread of infectious diseases.
