Lowering a tilt table in 5-10-degree increments until the blood pressure stabilizes is the most appropriate response when a patient experiences a sudden decrease in blood pressure. This gradual approach allows for better monitoring of the patient's response to the positional change. It helps ensure that excessive postural change does not exacerbate hypotension or cause additional distress.

This method allows the healthcare provider to assess how the patient is tolerating each incremental change, providing an opportunity to stabilize their condition before making further adjustments. It is crucial to closely monitor vital signs throughout this process to ensure the patient's safety and comfort. If blood pressure does stabilize, further intervention may be assessed based on the patient's condition.

Other options either suggest immediate, more drastic changes that might not provide the necessary stability or fail to address the need for close monitoring through gradual adjustments. Immediate lowers to 0 degrees or calling for emergency services might overlook the benefit of a more controlled adjustment, which should first be attempted in such situations.
