Which two vital signs are CNAs often responsible for measuring?

The responsibility of measuring vital signs is a fundamental role of Certified Nursing Assistants (CNAs) in patient care. Blood pressure and heart rate are two critical vital signs that CNAs frequently monitor. Blood pressure provides essential information about the cardiovascular system and can indicate potential health issues such as hypertension or hypotension. The heart rate, or pulse, reflects the heart's efficiency in pumping blood and can signal various conditions depending on whether it is too fast, too slow, or irregular.

When measuring blood pressure, CNAs typically use a sphygmomanometer and stethoscope or an automated blood pressure cuff, and for heart rate, they can feel the pulse at various points on the body or use electronic monitoring. These measurements are essential indicators of a patient's overall health and are often taken at the beginning of a shift or when there are changes in a patient's condition.

The other choices involve measurements that may be important in healthcare but do not align as closely with the primary vital signs monitored by CNAs. Temperature is another vital sign monitored, but when placed alongside weight, it does not encompass the same critical nature as blood pressure and heart rate. Respiration rate and temperature focus on different health aspects and are valuable, but blood pressure and heart rate are more commonly
