A medical assistant is instructed to gather vitals from a patient who has pyrexia. The assistant should expect which of the following vital signs to be outside the expected reference range?
Heart rate
Temperature
Respiratory rate
Blood pressure
The Correct Answer is B
A. Heart rate: Pyrexia (fever) often leads to an increased heart rate as the body attempts to regulate its temperature. Therefore, heart rate may be higher than normal.
B. Temperature: Pyrexia indicates an elevated temperature, so the temperature would be outside the expected reference range due to the fever.
C. Respiratory rate: While fever can sometimes affect the respiratory rate, it is not as directly impacted as heart rate or temperature. Respiratory rate may be slightly elevated but is less consistently affected compared to heart rate and temperature.
D. Blood pressure: Fever does not typically cause significant changes in blood pressure. It is less likely to be outside the expected reference range compared to heart rate and temperature.
