Answer 2

The correct answer is OPTION C: his body temperature after running.

• Body temperature causes an increase in heart rate of around 10 beats per minute per degree centigrade.
• Body temperature does not affect the respiratory rate.
• This quantification may aid in the evaluation of the hot and sick child, allowing doctors to determine whether any tachycardia or tachypnoea is solely attributable to the fever, or if there is a component of simultaneous shock present.
