For a patient with severe unilateral flank pain and stable vital signs, what is the most appropriate EMS action?

• A. Administer aspirin
• B. Transport the patient
• C. Apply heat
• D. Place patient in Trendelenburg

Answer: (B)

When a patient has severe unilateral flank pain but stable vital signs, the priority is to get them to a facility where imaging and definitive evaluation can be done. Flank pain can be caused by kidney stones, but also by other serious conditions that require CT imaging or lab work to distinguish, such as appendicitis, pyelonephritis, or even less common emergencies. EMS care focuses on maintaining airway, breathing, and circulation, controlling pain within protocol, and quickly transporting so the patient can receive appropriate diagnostic tests and definitive treatment.

Administering aspirin on scene isn’t the primary action here because the goal is urgent evaluation and imaging rather than on-scene treatment alone. Applying heat may offer some comfort but does not address the need for diagnostic imaging. Placing the patient in a Trendelenburg position is not indicated for flank pain and can be harmful. Therefore, the most appropriate action is to transport the patient promptly to the emergency department for further assessment and management.
