They monitor and document vital signs, such as blood pressure and temperature
One of the primary duties of a certified nursing assistant (CNA) in a hospital is to monitor and document patients' vital signs. This includes taking and recording a patient's temperature, blood pressure, heart rate, oxygen levels, respiration rate, and pulse rate. CNA responsibilities may also extend to monitoring patients' food and liquid intake, as well as their urine output, and performing basic medical tasks such as wound care and catheter care.
CNAs are trained healthcare workers who support registered nurses (RNs) and licensed practical nurses (LPNs) in ensuring that patients receive quality care. They are often responsible for taking vital signs, especially before a doctor's visit, as this is typically one of the first steps of a patient's visit to a hospital. CNAs may also be tasked with serving meals to patients, making beds, and cleaning rooms.
The monitoring of vital signs is an important aspect of a CNA's role as it helps ensure patient safety and provides an initial assessment of a patient's health status. CNAs may use machines to monitor these vital signs, and in some cases, this monitoring needs to be done hourly for patients in more critical or acute conditions.
In addition to monitoring vital signs, CNAs may also assist with patient transfers and discharges, provide emotional support to patients and their families, and communicate with other medical professionals about patient care. They play a crucial role in observing and reporting any changes in a patient's physical and emotional condition, which can significantly impact their recovery journey.
The specific duties of a CNA can vary depending on the state, healthcare setting, and facility policies. However, their primary focus remains on providing direct patient care and ensuring patient safety and well-being.

CNAs also collaborate with nurses and doctors to ensure continuity of care. They may communicate care plans and updates to the medical team, ensuring everyone is aware of the patient's needs and progress. For instance, a CNA may inform the nurse about a patient's dietary restrictions or preferences, enabling the nurse to make informed decisions about meal plans.
In addition to verbal communication, CNAs also utilise documentation and record-keeping to communicate with nurses and doctors. They maintain patient records, document vital signs, and track patients' intake and output of food, drinks, and medications. These records provide valuable data for nurses and doctors to make informed decisions about patient care.
