Final answer:
After a fainting spell, stay with the person for at least 15 to 20 minutes to ensure their stable recovery, and monitor for any continuing symptoms or signs of discomfort.
Step-by-step explanation:
When someone experiences a fainting spell, it's important to stay with them to monitor their recovery. Generally, once the person regains consciousness, you should stay with them for at least another 15 to 20 minutes to ensure they are fully coherent and stable. Monitor their vital signs, like pulse and breathing, and observe for any signs of confusion or weakness. If any unusual symptoms like a “pins-and-needles” feeling continue or they display other concerning symptoms, it could be indicative of a more serious condition, and medical attention may be required immediately.
