Verified step by step guidance

Understand the context: Increased intracranial pressure (ICP) refers to a rise in the pressure inside the skull, which can affect brain function. Recognizing signs and symptoms is crucial for diagnosis and treatment.

Identify early signs: Early signs of increased ICP often include symptoms like headache, nausea, vomiting, and blurred vision. These occur as the pressure begins to affect the brain.

Recognize late signs: As ICP continues to rise, more severe symptoms can develop. Cushing's triad is a classic late sign of increased ICP, characterized by three specific symptoms: hypertension (increased blood pressure), bradycardia (decreased heart rate), and irregular respirations.

Differentiate between early and late signs: Compare the options given in the problem. Nausea and vomiting, blurred vision, and headache are typically early signs, while Cushing's triad is a late sign.

Conclude with the correct identification: Based on the understanding of early and late signs, identify Cushing's triad as the late sign of increased intracranial pressure from the options provided.
