What is the definition of Rescue Medication?

Rescue medication is defined as a medication that is specifically used to relieve acute symptoms or episodes, particularly those related to conditions like asthma or severe anxiety. These medications are usually administered on an as-needed basis (PRN) and are designed to provide immediate relief, such as alleviating shortness of breath.

In the context of the options provided, the choice related to being ordered as PRN to treat shortness of breath aligns perfectly with the definition of rescue medication. This captures the essence of what rescue medication is intended for: it is not for regular, daily use or preventive care but rather for situations when symptoms suddenly escalate and require prompt treatment.

Daily maintenance medications aim to keep a condition stable over time and are not categorized as rescue medications. Similarly, preventive care medications are taken to prevent future symptoms rather than to address acute episodes, which does not fit the definition of rescue medication. Emergency use alone is too broad, as rescue medications can also be used in less critical situations where immediate relief is required. Therefore, the identification of the specific need for immediate symptom control establishes the information about rescue medications accurately.
