    Given a patient's risk assessment profile represented as a binary number where each bit indicates a specific health indicator's status, develop a function that identifies and activates the leftmost inactive health indicator (represented by 0) to complete the patient's risk evaluation profile. The function should take the existing risk profile as input and return the modified profile with the leftmost unmonitored health indicator now set to active (1), enabling a more comprehensive readmission risk assessment.
