Verified step by step guidance1
Step 1: Understand the concept of first-line defenses in infection control. These are measures taken to prevent the spread of infection, often involving personal protective equipment (PPE) and hygiene practices.
Step 2: Review the purpose of hand hygiene in infection control. Hand hygiene is a critical practice to reduce the transmission of pathogens and is often performed before or after donning PPE.
Step 3: Examine the role of each PPE item listed in the options. For example, gowns and masks are typically used to protect the wearer from exposure to infectious agents and are often donned before performing hand hygiene.
Step 4: Consider the sequence of donning PPE. Gowns and masks are usually donned first to ensure the wearer is protected before performing hand hygiene, which is a standard protocol in infection control.
Step 5: Confirm that the correct answer aligns with standard infection control practices. Gown and mask are typically donned before performing hand hygiene as part of first-line defenses.
