Question 1

What is the single most effective method to prevent healthcare-associated infections (HAIs)?

Accepted Answer

Proper hand hygiene

Answer

Proper hand hygiene remains the cornerstone of infection prevention as it breaks the chain of transmission most effectively.

Question 2

Standard precautions in healthcare settings apply to:

Accepted Answer

All patients regardless of known infectious status

Answer

Standard precautions apply universally to all patients because infectious status is not always known at the time of care.

Question 3

According to WHO's 'Five Moments of Hand Hygiene,' when should healthcare workers perform hand hygiene?

Accepted Answer

Before patient contact, before aseptic tasks, after body fluid exposure, after patient contact, and after touching patient surroundings

Answer

WHO's Five Moments cover the full cycle of care — before touching the patient, before clean/aseptic procedures, after body fluid exposure risk, after touching the patient, and after touching patient surroundings.

Question 4

Which type of transmission-based precaution is required for a patient with active pulmonary tuberculosis?

Accepted Answer

Airborne precautions

Answer

TB is transmitted via airborne droplet nuclei (<5 µm) that remain suspended in air, requiring airborne precautions including a negative-pressure room and N95 respirator.

Question 5

What is the correct sequence for donning (putting on) PPE?

Accepted Answer

Gown → Mask/respirator → Eye protection → Gloves

Answer

Donning proceeds from the largest item to the smallest: gown first (body protection), then mask/respirator, then eye protection, and finally gloves (which cover cuffs of the gown).
