Which of the following is a risk associated with high-alert medications?

High-alert medications are specifically identified due to their potential to cause significant harm to patients if they are misused or administered incorrectly. The key characteristic that categorizes these medications as high-alert is the increased risk of adverse events associated with errors in their usage. This includes situations such as incorrect dosing, incorrect administration routes, and other mistakes that can lead to severe complications or even death.

Understanding this context highlights the critical need for healthcare professionals to exercise heightened awareness and implement stringent safety measures when handling high-alert medications. This might involve the use of error-prevention strategies such as double-checking dosages, employing safeguards in prescribing practices, and enhancing communication during transitions of care.

On the other hand, low cost, limited availability, and ease of administration are not defining characteristics of high-alert medications. These factors may influence the use of medications but do not inherently relate to the risks when errors occur with these specific types of drugs. It's the potential for significant patient harm that firmly establishes the categorization of these medications as high-alert.
