Final answer:
Respiration rate (C) is included in a patient's vital signs. A patient's vital signs are measurements that indicate the state of the body's basic functions, and include body temperature, heart rate, breathing rate, and blood pressure.
Step-by-step explanation:
The vital signs that are used to measure the body's basic functions typically include the following:
- Body temperature (normally 37 °C [98.6 °F])
- Heart rate (normally 60-100 beats per minute)
- Respiration rate (normally 12-18 breaths per minute)
- Blood pressure (normally between 90/60 and 120/80 mm Hg)
Among the options provided in the question, C) respiration rate is included in a patient's vital signs. The other options such as visual acuity, reflexes, chest circumference, and height and weight are not considered vital signs. Monitoring respiration rate alongside other vital signs can provide crucial indications of a patient's health status, and changes in these measurements may be indicative of disease or a medical condition that requires attention.
