Which of the following is true regarding the use of N95 respirators?

Answer: D. Wearing goggles only when there is a risk of splashing

Rationale:

A) Wearing gloves when handling non-infectious materials:

Gloves should be worn when there is a potential for contact with blood, body fluids, or contaminated surfaces. Wearing gloves when handling non-infectious materials is unnecessary and can contribute to unnecessary waste of resources.

B) Reusing a disposable gown after disinfection:

Disposable gowns are designed for single-use and should not be reused, even after disinfection. Reusing disposable gowns increases the risk of contamination and infection transmission. Proper use involves discarding the gown after a single use and using a new gown for each patient or procedure.

C) Wearing a surgical mask in place of a respirator when caring for a patient with tuberculosis:

A surgical mask does not provide adequate protection against airborne pathogens like tuberculosis. An N95 respirator or higher-level respirator is required to protect healthcare workers from inhaling infectious airborne particles. Using a surgical mask in this context is inappropriate and unsafe.

D) Wearing goggles only when there is a risk of splashing:

Goggles or face shields should be used when there is a risk of splashing or spraying of blood, body fluids, secretions, or excretions. This is appropriate use of PPE to protect the eyes and mucous membranes from exposure to potentially infectious materials.

N95 respirators should be fit-tested to ensure a proper seal and provide adequate respiratory protection.

Incorrect choices:

a. N95 respirators should only be used when there is a risk of airborne transmission, such as caring for patients with airborne infections.

b. N95 respirators are not designed for multiple reuse and should be disposed of properly after use to prevent contamination and maintain effectiveness.
