Explanation

10 minutes.
Savlon is a combination of Chlorhexidine and Cetrimide.
For disinfection of items like glassware and thermometers, a 5% solution of Savlon (which is a 1:20 dilution) requires a minimum contact time of 10 minutes to be effective against vegetative bacteria.
Adhering to the specified contact time is critical for ensuring proper disinfection and preventing cross-contamination in a clinical setting.

Option B: A contact time of 5 minutes is insufficient for a 5% Savlon solution to achieve adequate disinfection of glassware.
Option C: 7 minutes is not a standard recommended duration for disinfection with 5% Savlon and would not guarantee the elimination of required pathogens.
Option D: Similar to the other incorrect options, 9 minutes is less than the required minimum time and would result in incomplete disinfection.

Clinical Relevance

Nursing practice connection: Knowing Infection control and disinfection protocols in a hospital setting helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Proper disinfection is a cornerstone of infection prevention and control in healthcare, directly impacting patient safety by preventing healthcare-associated infections (HAIs).
Nurses are directly responsible for ensuring that equipment is correctly disinfected before use. Failure to follow protocols, such as correct contact time, can lead to the transmission of pathogens between patients.
What if? If an instrument is only immersed for 5 minutes instead of the required 10, it is not considered disinfected. Using this instrument could introduce pathogenic microorganisms to the next patient, leading to a potential infection. The nurse must restart the process for the full duration.

How to Approach the Question

Identify the key elements in the question: the specific disinfectant (5% Savlon), the items to be disinfected (glassware), and what is being asked (minimum duration).
This is a factual recall question based on standard infection control protocols.
Recall the standard contact times for common hospital disinfectants. If unsure, try to eliminate options that seem too short or are not standard time intervals (like 7 or 9 minutes).
Compare the properties of Savlon with other disinfectants like Dettol or Lysol to solidify your knowledge.
Select the option that matches the established guideline for the specified chemical and concentration.
