Which position is recommended for a patient experiencing anaphylaxis while awaiting EMS?

• A. Sit upright.
• B. Stand up.
• C. Left lateral decubitus.
• D. Lay patient flat or with legs elevated as advised.

Answer: (D)

During anaphylaxis, the priority is to support circulation as blood pressure can drop from the systemic reaction. Lying the patient flat with the legs elevated improves venous return to the heart, helping maintain perfusion to the brain and vital organs while EMS is en route. Standing or sitting upright would reduce venous return and can worsen dizziness or shock. Left lateral decubitus isn’t the default here unless the person is unconscious and at risk of aspiration; in that case a recovery position may be used, but for awaiting EMS, laying flat with legs elevated is the recommended approach.
