Explanation

The correct sequence for doffing PPE aims to remove the most contaminated items first to minimize self-contamination.
Gloves are removed first as they are in direct contact with infectious materials.
Eye protection (goggles) is removed next, followed by the gown.
The mask or respirator is removed last, ideally outside the patient's room, to protect the healthcare worker's respiratory system until they have left the immediate contaminated environment.
Hand hygiene is a critical step performed after the removal of all PPE to eliminate any remaining microorganisms on the hands.

Option A: This option incorrectly places the removal of the mask before the gown and eye goggles. The mask should be removed last to protect the respiratory tract until the worker is away from the source of infection.
Option C: This option incorrectly suggests removing the mask before the eye goggles. The mask should be the last piece of PPE to be removed to ensure continuous respiratory protection.
Option D: This option presents an incorrect order (mask before goggles) and, most critically, omits the removal of gloves, which are the first and most contaminated item to be doffed.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Infection Control: Sequence of Doffing Personal Protective Equipment (PPE) as background academic context rather than a clinical decision trigger.
Proper doffing technique is a fundamental skill for all healthcare workers to prevent healthcare-associated infections (HAIs) and protect themselves from occupational exposure to pathogens.
Incorrect doffing is a common cause of self-contamination, which can lead to illness in the healthcare worker and further spread of infection to other patients and colleagues.
What if? If a patient is on airborne precautions (e.g., Tuberculosis, COVID-19), the N95 respirator must be removed last, after exiting the patient's room and closing the door, to prevent inhalation of aerosolized particles.

How to Approach the Question

First, understand the question is asking for the sequence of doffing, which means removing PPE.
Recall the core principle of doffing: move from 'most contaminated' to 'least contaminated' areas, while protecting your face and airways until the end.
Identify the most contaminated item: gloves are always considered the most contaminated and are removed first.
Identify the last item to be removed: the mask/respirator is removed last to protect your airway until you are clear of the contaminated environment.
Evaluate the options based on these two key steps (gloves first, mask last). The sequence should be Gloves -> Goggles/Shield -> Gown -> Mask.
Select the option that most closely matches the correct sequence of equipment removal, even if the inclusion of 'hand hygiene' in the option is awkwardly placed.
