Which action aligns with ethical guidelines that health coaches should follow?

Practicing confidentiality is paramount in the field of health coaching and aligns closely with ethical guidelines that health coaches should adhere to. Confidentiality fosters trust between the coach and the client, which is essential for a productive relationship. Clients are more likely to share sensitive information if they are assured that their privacy will be protected.

Maintaining confidentiality also helps ensure compliance with legal and ethical standards related to personal health information. Health coaches must protect the rights of clients by not disclosing their information without explicit consent unless legally required. This principle is foundational for professional integrity and ethical practice in health coaching.

The other options, while relevant to the context of coaching practice, do not align with ethical guidelines. Arriving late to sessions may reflect a lack of professionalism, being vague about payment terms can lead to misunderstandings and potential ethical breaches, and ignoring conflicts of interest can compromise the coach's objectivity and the client's best interests.
