Minnesota State Certified Nursing Assistant (CNA) Practice Exam 2025 - Free CNA Practice Questions and Study Guide

The role of a CNA in monitoring vital signs primarily involves accurately measuring and reporting any changes to the nursing staff. This task is essential because vital signs—such as temperature, pulse, respiration, and blood pressure—serve as critical indicators of a patient's health status. By providing precise measurements and noting any variations, a CNA aids in the ongoing assessment and monitoring of a patient's condition, allowing nursing staff to make informed decisions regarding care.

The importance of this responsibility lies in the CNA's position as a crucial member of the healthcare team, acting as a liaison who can identify potential changes that may require immediate attention from nurses or other healthcare professionals. Thus, the accurate reporting of vital signs is vital for ensuring patient safety and timely intervention.

In contrast, independent diagnosis and treatment planning fall outside the CNA's scope of practice, as these are responsibilities designated to licensed nurses and physicians who have the required training and education to evaluate complex health issues and create comprehensive care plans. Similarly, administering medications is also a task reserved for licensed nursing staff, as it necessitates specific training and knowledge about pharmacology and patient safety protocols.
