Accepting the assignment creates the appearance of an impairment to her professional judgment and objectivity. This is because the individual is auditing an area where she will soon work, which could potentially influence her audit work, either consciously or unconsciously, due to personal interest in the future role.References: IIA Standards on Independence and Objectivity

Risk management is not solely about mitigating or eliminating potential hazards but also involves identifying and seizing potential opportunities that can benefit the organization. Effective risk management allows an organization to balance risk and reward, making informed decisions that align with its strategic objectives.
This approach ensures a proactive stance in optimizing performance and achieving competitive advantage while managing risks.

The statement that articulating measurable objectives is part of internal control is true. A system of internal control is designed to help an organization achieve its objectives, and these objectives need to be clearly stated and measurable to effectively assess and control risks related to them.References: COSO Framework for Internal Control, which emphasizes the importance of clear, measurable objectives in effective internal control systems.

To effectively determine whether ethical values are followed throughout an organization, internal auditors should review employee survey responses and follow up on those that suggest weaknesses in the ethical climate. This approach allows auditors to gather firsthand insights from employees about the actual ethical environment, which can be more telling than formal documentation or compliance with written policies alone.
It provides a direct measure of the ethical culture as experienced and perceived by the employees themselves.References: Institute of Internal Auditors (IIA) - International Standards for the Professional Practice of Internal Auditing; Guidance on assessing organizational culture.

Surveying employees to determine whether they are aware of the ethics hotline is the most effective action to help an internal auditor assess how successful the organization has been in communicating the existence of its ethics hotline. Employee surveys can provide direct feedback on their awareness and understanding of the hotline, allowing the auditor to gauge the effectiveness of communication efforts and identify areas where additional outreach or education may be necessary.References:
