For basic life support techniques, a child is defined as someone between the ages of

• A. 1 and 8
• B. 0 and 8
• C. 2 and 10
• D. 5 and 10

Answer: (A)

In basic life support, age groups guide how you perform CPR because size and physiology change as children grow. A child is defined as someone between 1 and 8 years old, so the best answer is 1 through 8. This range separates infants (under 1 year) from older children and adolescents, who follow different guidelines. Choices that include 0 would cover infants, and options that go beyond 8 would include older youths who are typically managed with adolescent or adult protocols, not the pediatric child guidelines. Understanding this helps you apply the appropriate technique—like compression depth and rate—for that specific age group.
