Which of the following is NOT part of the early signs of increased intracranial pressure?

• A. Vomiting
• B. Altered LOC
• C. Headache
• D. Increased heart rate

Answer: (D)

The question tests recognizing early signs of increased intracranial pressure versus later changes. Early signs reflect direct effects on brain structures: vomiting occurs from irritation of the vomiting center in the medulla, headache from stretching of the meninges, and changes in level of consciousness from impaired cerebral function. Increased heart rate is not typical early; as ICP advances and brainstem involvement develops, the body often shows the opposite pattern—bradycardia with hypertension and irregular respirations (the Cushing triad). So the option describing an increased heart rate is not an early sign.
