Multiple Choice

Name a high-level disinfectant commonly used for semi-critical items.

The key concept is matching the disinfection level to the item’s use. Semi-critical items contact mucous membranes or non‑intact skin, so they must undergo high‑level disinfection to inactivate a broad range of microorganisms, including many viruses and mycobacteria. Glutaraldehyde‑based disinfection solutions (or other high‑level chemical sterilants) provide that level of disinfection. They are specifically designed to achieve the broad microbial kill needed for semi-critical gear with the appropriate contact time, making them the standard choice for these items. Alcohol wipes, by contrast, act mainly as intermediate‑level disinfectants and may not reliably kill all relevant organisms, especially spores. Soap and water clean but do not disinfect to a high level. Bleach can disinfect and is useful in some settings, but it can be corrosive or damaging to equipment and isn’t universally suitable for all semi-critical devices. So, the best option for high‑level disinfection of semi‑critical items is the glutaraldehyde‑based high‑level disinfectants.
