What is the definition of Rescue Medication?

The definition of Rescue Medication refers specifically to medications that are used to provide immediate relief in acute situations, such as treating shortness of breath or other urgent symptoms. These medications are typically prescribed as needed (PRN) to alleviate severe symptoms quickly, making them distinct from medications intended for long-term management or preventive care.

When considering the correct answer, "Ordered as PRN to treat shortness of breath" fits perfectly within this definition because it highlights the use of these medications in an emergency or acute context, precisely when quick action is necessary to stabilize a patient's condition. For instance, bronchodilators used by individuals with asthma serve as rescue medications to promptly relieve an asthma attack.

Other options do not align with the concept of rescue medications. Daily maintenance medications are intended for ongoing treatment and do not provide immediate relief. Medications used for preventive care focus on reducing the likelihood of future health issues rather than addressing acute symptoms. Lastly, while medications taken in emergencies might sound similar, the term "rescue medication" specifically refers to those that are used immediately to relieve urgent symptoms, not just those that are taken during emergencies.
