Rationale: In a child with a head injury, the development of diabetes insipidus can occur due to pituitary hypofunction, leading to a deficiency of antidiuretic hormone. An elevated sodium level (hypernatremia) is a key finding in diabetes insipidus due to the excessive loss of free water in the urine, resulting in increased sodium concentration in the blood.

Correct Answer: A

Rationale: Positioning the newborn in a semi-Fowler position is appropriate as it helps prevent aspiration in suspected EA/TE fistula. This position helps reduce the risk of regurgitation and aspiration of gastric contents. Placing the newborn in a semi-Fowler position promotes the drainage of secretions and reduces the risk of complications while awaiting further assessment by the healthcare provider.

The persistent fever is a hallmark feature of the disease and can last for more than five days despite treatment with antipyretics.

Correct Answer: C

Rationale: The correct answer is hypotonic dehydration. The combination of high hemoglobin and hematocrit with low serum sodium indicates hypotonic dehydration. In this condition, there is an excess of solutes relative to water, leading to higher red blood cell concentration (elevated hemoglobin and hematocrit) and low serum sodium levels.
