Explanation

1% sodium hypochlorite is the universally recommended standard disinfectant for managing blood and body fluid spills in healthcare settings.
This concentration provides approximately 10,000 parts per million (ppm) of available chlorine, which is highly effective at neutralizing bloodborne pathogens like HIV and Hepatitis B.
It offers a crucial balance between potent microbicidal activity and an acceptable level of corrosiveness and toxicity for routine use on spills.
Guidelines from health authorities consistently specify a 1% solution for decontaminating surfaces contaminated with potentially infectious material.

Option A: A 10% solution is excessively strong and corrosive for routine spill management. Its use is reserved for specific high-risk situations, such as very large spills of cultured pathogens in a laboratory setting, not for general clinical areas.
Option C: A 5% solution typically represents the stock concentration of household bleach. It is meant to be diluted before use. Using it undiluted is unnecessarily harsh, corrosive to surfaces, and creates excessive fumes.
Option D: A 2% solution is not a standard concentration recommended by major infection control guidelines for spill management. It does not align with the established protocols that call for a 1% solution (for spills) or a 0.5% solution (for general disinfection).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Infection Control and Spill Management as background academic context rather than a clinical decision trigger.
Using the correct disinfectant concentration is a critical nursing responsibility for ensuring both patient and healthcare worker safety. An incorrect concentration can either fail to kill pathogens or cause chemical hazards.
Nurses must be proficient in preparing fresh disinfectant solutions daily, as the chlorine in hypochlorite solutions degrades over time, especially when exposed to light, reducing its effectiveness.
What if the spill is urine without any visible blood? While a lower concentration (e.g., 0.5%) might be used for routine cleaning, any spill of body fluid should be treated as potentially infectious. Therefore, using the standard 1% solution is the safest and most appropriate action to prevent cross-contamination.

How to Approach the Question

Identify the core of the question: it's asking for the standard, recommended disinfectant for 'spills' in a healthcare setting.
Recognize that 'spills' implies potential contamination with blood or body fluids, requiring a potent disinfectant.
Recall standard infection control protocols. The key is to remember the specific concentration, not just the chemical name.
Evaluate the options based on standard practice. Eliminate concentrations that are too high (10%), too low, or non-standard (2%). Recognize that 5% is the stock solution, not the working solution.
Select the option that matches the established guideline for decontaminating biohazardous spills, which is 1% sodium hypochlorite.
