Which of the following findings indicate increased intracranial pressure in an Infant?

The correct answer is A: Increased somnolence. Increased somnolence in an infant indicates increased intracranial pressure due to brain compression affecting the level of consciousness. Choice B, increased heart rate, is not a direct indicator of intracranial pressure. Choice C, depressed fontanels, can indicate dehydration but not specifically increased intracranial pressure. Choice D, brisk pupillary reaction to light, is a normal finding and not indicative of increased intracranial pressure in infants.
