Texas Certified Nursing Assistant (CNA) Practice Exam 2025 – Comprehensive All-in-One Guide for Exam Success

The responsibility of a nursing assistant involves a variety of tasks aimed at providing direct care and support to patients. One critical aspect of a nursing assistant's role is to offer emotional support, assist with mobility, and prepare meal trays, which all directly contribute to patient well-being and comfort in a healthcare setting.

Dilating pupils during examination is typically outside the scope of practice for a nursing assistant. This task requires specialized knowledge and skills generally reserved for licensed healthcare professionals, such as nurses or doctors. Nursing assistants focus on supportive and non-invasive tasks that help ensure patients have their basic needs met, rather than performing procedures that require a medical license or specialized training. Therefore, the option related to dilating pupils represents a task not aligned with the typical responsibilities of a nursing assistant.
