Rationale: The correct first step for thermal protection of a newborn is to dry the baby thoroughly immediately after birth. This helps prevent heat loss and is crucial in maintaining the baby's body temperature. Choice B, covering the baby with a clean, dry cloth after the cord has been cut, is not the initial step as drying the baby comes first. Choice C, drying the baby thoroughly after the cord has been cut, is also not the first step. Choice D, covering the baby with a clean, dry cloth immediately after birth, is not as effective as drying the baby to prevent heat loss.

Correct Answer: B

Rationale: The correct answer is to inspect the nares and ears for skin breakdown. This is important because the nasal cannula can cause skin breakdown due to prolonged use and friction. Ensuring that the skin is intact helps prevent complications. Choice A is incorrect as oxygen therapy via a nasal cannula does not involve mist. Choice C is incorrect as lubricating the tips of the cannula is not a standard practice and may lead to complications. Choice D is incorrect because while cleanliness is important, maintaining sterile technique is not necessary for handling a nasal cannula in this context.

Correct Answer: C

Rationale: Chest indrawing and stridor are signs of severe respiratory distress. In this situation, immediate referral is essential. Giving the first dose of antibiotics before referral can help initiate treatment, but urgent referral for further evaluation and management is crucial. Choice A is incorrect because simply changing the antibiotic without assessing the severity of the symptoms and providing urgent care is not appropriate. Choice B is incorrect as advising the mother to observe the child and continue antibiotics delays necessary intervention for a potentially life-threatening condition. Choice D is incorrect as observing the child at the center is not sufficient when signs of severe illness are present.
