Paper I
Question
List 4 disinfectants with respective application in the hospital.
Answer
Four disinfectants with their respective hospital applications:
- 70% Isopropyl/Ethyl alcohol — skin antisepsis before injections/venepuncture, and disinfection of small equipment surfaces (e.g., stethoscope diaphragms).
- 1% Sodium hypochlorite — disinfection of blood/body fluid spills and general environmental surface disinfection.
- 2% Glutaraldehyde (activated) — high-level disinfection of heat-sensitive semi-critical medical equipment (e.g., endoscopes, bronchoscopes).
- Povidone-iodine (5–10%) — pre-surgical skin preparation/antisepsis and wound cleaning.
(Other valid examples: chlorhexidine — surgical hand scrub/skin antisepsis; formaldehyde — fumigation of rooms/equipment.)
