Ans. D. False True False True TrueEmergency care providers should check the victim's pulse for at least 5 seconds but no longer than 10 seconds. For children aged one to adolescence, the pulse should be checked at the carotid aery. In infants, the brachial pulse should be assessed.If there is a palpable pulse within 10 seconds, then a rescue breath should be given every 3 seconds. Breaths should last one second and the chest should be observed for visible rise. If the victim has an advanced airway, then the provider should administer breaths 10-12 times per minute.If the pulse is less than 60/minute, or if the victim has signs of poor perfusion after adequate ventilation and oxygenation, the provider should begin chest compressions. In the absence of a pulse, a lone rescuer should begin CPR with 30 high quality compressions followed by two breaths. If two healthcare providers are available, the cycle of compressions to breaths should be 15:2 (pediatrics).High quality compressions in CPR should be a minimum of 1/3 the AP diameter of the chest, or approximately 1 1/2 inches in infants (4 cm) and 2" in children from age one to adolescence. The rate of compressions should be 100-120 per minute. Chest recoil should be complete between compressions.Pediatric compression is performed with the head of one hand over the lower 1/2 of the sternum, between the nipples. In infants, use two fingers, or use the thumb encircling technique if multiple providers are available
