the \portal of entry\ for a blood borne infectious pathogen is:
o not washing hands after using the bathroom
a cut on the skin
the nose or the mouth
ingesting spoiled food

Explanation:

Blood - borne pathogens are microorganisms that can cause disease and are present in human blood. A cut on the skin can provide a direct route for these pathogens to enter the body. Ingesting spoiled food (related to food - borne pathogens), the nose or mouth (more related to airborne or droplet - transmitted pathogens in some cases), and not washing hands after using the bathroom (more related to fecal - oral route for some pathogens) are not the typical "portal of entry" for blood - borne pathogens.

Answer:

a cut on the skin
