A nurse is caring for a client who had a stroke 6 hr ago. Which of the following interventions should the nurse implement to reduce the risk of increased intracranial pressure (ICP)?

A. Flexing the client's neck forward can increase intracranial pressure by impeding venous drainage from the brain and increasing cerebral blood volume. Therefore, this choice is incorrect. B. Grouping several nursing activities to be completed at one time can increase intracranial pressure by stimulating the client and causing fluctuations in blood pressure and heart rate. Therefore, this choice is incorrect. C. Limiting suctioning the client's airway to 30 seconds at a time can reduce intracranial pressure by minimizing hypoxia and hypercarbia, which can cause cerebral vasodilation and increased cerebral blood volume. However, this intervention alone is not sufficient to prevent increased intracranial pressure, and suctioning should be done only when necessary and with caution. Therefore, this choice is partially correct but not the best answer. D. Placing the client in a quiet environment can reduce intracranial pressure by minimizing sensory stimulation and promoting relaxation, which can lower blood pressure and heart rate and decrease cerebral metabolic demand. Therefore, this choice is correct and the best answer.
