What should be the depth of chest depression while giving C.P.R.?

Correct option is A

Answer: (a) 3 inches (Closest correct option, though 2–2.4 inches is the recommended range.)
Explanation:
· The American Heart Association (AHA) recommends a chest compression depth of at least 2 inches (5 cm) but not more than 2.4 inches (6 cm) for adults and adolescents during CPR.
· For children (1 year to puberty), the compression depth should be about 2 inches (5 cm).
· For infants (under 1 year), the depth should be about 1.5 inches (4 cm).
Evaluation of the Given Options:
· (b) 1.5 inches → Correct for infants but too shallow for adults.
· (c) 5 inches → Too deep, may cause internal injuries.
· (d) 4 inches → More than recommended, except in rare cases.
· (a) 3 inches → While slightly deeper than recommended, it is the closest option available.
Thus, 3 inches (option a) is the best answer based on the given choices, but ideally, 2–2.4 inches is recommended for adults.
