TBI/ICP NCLEX Questions and answers Graded A+ 2024

In conducting a primary survey on a trauma patient, which of the following is considered one of the priority elements of the primary survey? a.) Complete set of vital signs b.) Palpation and auscultation of the abdomen c.) Brief neurologic assessment d.) Initiation of pulse oximetry - c.) Brief neurologic assessment Rationale: A brief neurologic assessment to determine level of consciousness and pupil reaction is part of the primary survey. Vital signs, assessment of the abdomen, and initiation of pulse oximetry are considered part of the secondary survey. A pediatric client is admitted to the neuro ICU with a closed-head injury sustained after falling out of a tree house. The mechanisms of injury this young client most likely sustained would be: a.) Acceleration b.) Penetrating c.) Rotational d.) Deceleration - d.) Deceleration Rationale: Deceleration injury occurs when the brain stops rapidly in the cranial vault. As the skull ceases movement, the brain continues to move until it hits the skull. The force of deceleration causes injury at the site of impact. An example of this is a victim of a fall. A client who has had a plaster of Paris cast applied to his forearm is receiving pain medication. To detect early manifestations of compartment syndrome, which of these assessments should the nurse make? A.) Observe the color of the fingers B.) Palpate the radial pulse under the cast C.) Check the cast for odor and drainage D.) Evaluate the response to analgesics - D.) Evaluate the response to analgesics A client admitted to the hospital with a subarachnoid hemorrhage has complaints of severe headache, nuchal rigidity, and projectile vomiting. The nurse knows lumbar puncture (LP) would be contraindicated in this client in which of the following circumstances? a.) Vomiting continues b.) Intracranial pressure (ICP) is increased c.) The client needs mechanical ventilation d.) Blood is anticipated in the cerebralspinal fluid (CSF) - b.) Intracranial pressure (ICP) is increased Rationale: Sudden removal of CSF results in pressures lower in the lumbar area than the brain and favors herniation of the brain; therefore, LP is contraindicated with increased ICP. Vomiting may be caused by reasons other than increased ICP; therefore, LP isn't strictly contraindicated. An LP may be preformed on clients needing mechanical ventilation. Blood in the CSF is diagnostic for subarachnoid hemorrhage and was obtained before signs and symptoms of ICP. A client with a subdural hematoma becomes restless and confused, with dilation of the ipsilateral pupil. The physician orders mannitol for which of the following reasons? a.) To reduce intraocular pressure b.) To prevent acute tubular necrosis c.) To promote osmotic diuresis to decrease ICP d.) To draw water into the vascular system to increase blood pressure - c.) To promote osmotic diuresis to decrease ICP Rationale: Mannitol promotes osmotic diuresis by increasing the pressure gradient, drawing fluid from intracellular to intravascular spaces. Although mannitol is used for all the reasons described, the reduction of ICP in this client is a concern. A client with subdural hematoma was given mannitol to decrease intracranial pressure (ICP). Which of the following results would best show the mannitol was effective? a.) Urine output increases b.) Pupils are 8 mm and nonreactive c.) Systolic blood pressure remains at 150 mm Hg
