A nurse collects the health history of a 65-year-old client. Which of the following risk factors in the client's history puts the client at the highest risk for embolic stroke?

Choice A reason: This is incorrect because a drop in heart rate from 74 to 68/min is not a manifestation that requires immediate reporting to the provider. A mild decrease in heart rate can be normal or due to other factors such as medication, sleep, or relaxation. It does not indicate a worsening of brain injury or increased intracranial pressure.

Choice B reason: This is the correct answer because a change in the Glasgow Coma Scale score from 14 to 10 is a manifestation that requires immediate reporting to the provider. The Glasgow Coma Scale is a tool that measures the level of consciousness based on eye-opening, verbal response, and motor responses. A score of 14 indicates mild impairment, while a score of 10 indicates moderate impairment. A decrease in score can indicate deterioration of neurological status and increased intracranial pressure, which can be life-threatening.

Choice C reason: This is incorrect because the headache is not a manifestation that requires immediate reporting to
the provider. Headache is a common symptom of mild TBI and can be managed with analgesics, rest, and hydration. It does not indicate a worsening of brain injury or increased intracranial pressure unless it is severe, persistent, or accompanied by other signs such as vomiting, confusion, or seizures.

Choice D reason: This is incorrect because diplopia is not a manifestation that requires immediate reporting to
the provider. Diplopia means double vision and can be caused by damage to cranial nerves or eye muscles due to TBI. It can be treated with eye patches, glasses, or surgery. It does not indicate a worsening of brain injury or increased intracranial pressure unless it is associated with other symptoms such as blurred vision, loss of vision, or eye pain.

Choice A Reason: This is incorrect because encouraging coughing and deep breathing can increase intracranial pressure (ICP), which is the pressure inside

the skull that can affect brain function. Coughing and deep breathing can increase blood flow and oxygen demand to the brain, which can worsen cerebral edema. The nurse should suction the patient as needed and maintain a patent airway.

Choice B Reason: This is incorrect because positioning the patient with knees and hips flexed can increase ICP by reducing venous drainage from the head. The nurse should position the patient with neck and body in alignment and avoid extreme flexion or extension of any joints.

Choice C Reason: This is incorrect because performing nursing interventions once an hour can disturb the patient's sleep and increase ICP by stimulating brain activity. The nurse should cluster nursing interventions and provide quiet and dark environment to promote rest and reduce stress.

Choice D Reason: This is correct because keeping the head of the bed elevated to 30 degrees can decrease ICP by facilitating venous drainage from the head and reducing cerebral blood volume. The nurse should monitor the patient's blood pressure and pulse to ensure adequate cerebral perfusion.
