Final answer:
Clients have the right to respect, privacy, informed consent, but not to mediocrity and negligence, which are considered violations of care standards.
Step-by-step explanation:
Clients have a right to treatment and a supportive environment that includes respect and dignity, privacy and confidentiality, and informed consent. These principles align with autonomy, beneficence, and the preservation of human rights. However, mediocrity and negligence are not rights but rather failures in care that violate professional and ethical standards. High-quality care is a cornerstone of health services, and negligence or substandard care is unacceptable. Clients are entitled to quality services that respect their autonomy, maintain confidentiality, protect them from harm, and require their informed consent before treatment.
