Question

Tachycardia is a normal physiologic response in the critically ill child?

1) True
2) False

Answer 1

Tachycardia is not a normal physiologic response in the critically ill child. The normal resting heart rates of children are above 100 bpm but not considered tachycardia. Tachycardia may be caused by various factors including fever, anemia, hypoxia, hyperthyroidism, and more.

Step-by-step explanation:

Tachycardia is not a normal physiologic response in the critically ill child. While tachycardia is defined as a heart rate above 100 bpm, the normal resting heart rates of children are often above 100 bpm, but this is not considered to be tachycardia. Many causes of tachycardia may be benign, but the condition may also be correlated with fever, anemia, hypoxia, hyperthyroidism, hypersecretion of catecholamines, some cardiomyopathies, some disorders of the valves, and acute exposure to radiation.
