Wearing a surgical mask in place of a respirator when caring for a patient with tuberculosis Explanation: When caring for a patient with tuberculosis, the appropriate use of PPE includes wearing a respirator to protect against airborne transmission of the infectious agent.

Incorrect choices:

a. Wearing gloves when handling non-infectious materials is unnecessary and does not align with appropriate PPE use.

b. Reusing a disposable gown after disinfection is not recommended as disposable gowns are meant for single-use to prevent cross-contamination.

d. Wearing goggles only when there is a risk of splashing does not provide adequate eye protection in all situations where eye exposure may occur.

The gown should be removed before the gloves. Explanation: When removing PPE, the gown should be removed before the gloves to prevent contamination of the hands during the process.

Incorrect choices: a. Gloves should be removed last after removing the gown to minimize the risk of contaminating the hands.

b. The mask should be donned before wearing gloves to ensure proper respiratory protection.

d. The mask should be removed after removing the goggles or face shield to maintain a barrier against respiratory droplets.

Touching clean surfaces with gloved hands

Explanation: Gloves should not be considered a substitute for hand hygiene. Touching clean surfaces with gloved hands can contaminate those surfaces, and proper hand hygiene should be performed after glove removal.

Incorrect choices: a. Wearing the same pair of gloves for multiple patient care tasks increases the risk of cross-contamination and is not recommended.

c. Gloves should be removed after completing all necessary patient care tasks and hand hygiene should be performed immediately.

d. Gloves should be removed and hand hygiene performed before touching clean surfaces.

When providing oral care to an unconscious patient, a gown should be worn to protect against potential contact with bodily fluids or contaminants.

Incorrect choices:

a. Wearing a gown during routine hand hygiene is unnecessary and not recommended.

c. Wearing a gown while transporting a stable patient within the facility is unnecessary unless there is a risk of contact with potentially infectious materials.

d. Wearing a gown when administering oral medication to a non-isolated patient is not typically required unless there is a risk of splashing or exposure to bodily fluids.

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.
