Explanation:

Question about Portal of Exit in Chain of Infection

In the chain of infection, a portal of exit is a path for the infectious agent to leave the reservoir. The nose is a common portal of exit as respiratory secretions (containing pathogens) can exit through it. Fingernail and hair are not typical portals of exit, and the ear is more of a portal of entry or not a primary exit for most pathogens.

Medical asepsis (like handwashing, using clean equipment) aims to reduce the number of microorganisms and prevent their spread, so the statement is true.

Gloves can have breaches or be contaminated on the outside. After a procedure, hands under gloves may still be contaminated, or gloves may have touched contaminated surfaces. So handwashing is necessary after removing gloves. Thus the statement is false.

Answer:

Nose
