Final answer:
An HHA must always wear gloves when working with cultures, handling contaminated specimens or equipment, or assisting a surgeon with invasive procedures.
Step-by-step explanation:
An HHA (Home Health Aide) must always wear gloves in the following situations:
- When working with cultures, such as in a laboratory setting.
- When handling contaminated specimens or equipment, or working with infected patients.
- When assisting a surgeon with invasive procedures.
In these situations, gloves provide a barrier and help prevent the spread of infections. It is important to follow proper hand washing techniques before and after wearing gloves.
