  1. “Correct Answer – Option 4 : Increased pupillary reaction

    CONCEPT: 

    • Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue.
    • ICP is measured in millimetres of mercury (mmHg) and at rest, is normally 7–15 mmHg for an adult. 

     

    EXPLANATION:  

    • Mannitol exerts its ICP-lowering effects via two mechanisms; an immediate effect because of plasma expansion and a slightly delayed effect related to its osmotic action.
    • Together, these effects result in an increase in regional cerebral blood flow and compensatory cerebral vasoconstriction in brain regions.

    Hence, the correct answer is Increased pupillary reaction.
