    Given a binary representation of a patient's vital sign monitoring status in the ICU, develop a function that identifies and activates the next unmonitored parameter (represented by 0) from left to right in the monitoring system. The function should take the current monitoring status as input and return an updated status with the leftmost unmonitored parameter now set to active (1), enabling enhanced patient surveillance capabilities.
