Final answer:
The question focuses on neonatal resuscitation techniques, particularly opening the airway by positioning the head and stimulating the baby to breathe.
Step-by-step explanation:
The subject of the question relates to the neonatal resuscitation procedures used in Health and Medicine. Specifically, Block A refers to ensuring an open airway for a newborn. To do this, the responder should position the baby's head to open the airway, which may involve slightly extending the neck (sometimes referred to as the 'sniffing' position). If necessary, any obstructions should be cleared from the nose or mouth; this is what 'Clear airway PRN' (as needed) implies. Additionally, drying the skin, stimulating the baby, and repositioning the head as needed are all methods employed to encourage the newborn to initiate breathing.
