A medical assistant is preparing for a procedure that can potentially expose them to body fluids. Which of the following actions should the assistant take before donning the personal protective equipment?

While wearing a surgical mask is important for protecting the respiratory system, it should not be the first action taken before donning PPE. Proper handwashing must occur first to minimize the risk of contaminating the mask and other equipment during the donning process.

Putting on a hair cover helps to prevent hair from contaminating the sterile field; however, it is not the priority action before donning PPE. Hand hygiene is essential first to ensure that hands are free of pathogens before touching any equipment or protective wear.

Disinfecting the patient's skin is a crucial step in procedure preparation but should occur after the medical assistant has completed hand hygiene and donned the appropriate PPE. The focus at this stage should be on the assistant's safety and preventing contamination during the process of preparing for the procedure.
