Which term best describes a procedure that is performed swiftly to treat an immediate health risk?

Choosing "urgent care procedure" is the most appropriate because this term specifically refers to medical interventions that are needed promptly to address a health issue that poses an immediate risk to a patient's health or safety. These procedures are typically performed quickly to prevent further complications or to stabilize the patient's condition.

In contrast, elective surgery refers to procedures that are planned in advance and are not urgent, allowing patients and healthcare providers to decide when the surgery will take place. A planned procedure generally denotes any operation that is scheduled ahead of time, regardless of whether it is urgent or elective. Reconstructive surgery is a type of plastic surgery aimed at repairing or reconstructing physical defects, which may not necessarily imply immediacy or urgency. Therefore, the term "urgent care procedure" precisely captures the need for swift action to address an immediate health concern, making it the correct choice.
