A client sustained a head injury when hit by a lead pipe two hours ago and is admitted for observation after the computerized tomography (CT) scan indicates that no spinal cord injury and no skull fractures are present. When the client begins projectile vomiting, the nurse quickly turns the client's head to the side and administers ondansetron 4 mg IV as prescribed. Reassessment indicates that the client's Glasgow coma score is 13 and the left pupil is dilated without reaction to light. Which intervention(s) should the nurse implement? Select all that apply.

Choice A rationale Placing a client with a head injury in the lateral Trendelenburg position is not recommended due to the risk of increasing intracranial pressure (ICP). This position can impede venous outflow from the brain, thereby exacerbating cerebral edema and ICP. Additionally, it can compromise the airway and lead to aspiration, especially in a client who is vomiting. Proper positioning, such as elevating the head of the bed to 30 degrees, is more appropriate to facilitate venous drainage and reduce ICP while protecting the airway. This choice is scientifically unsound and potentially harmful. Choice B rationale Scheduling a repeat CT scan is a critical intervention in this case. The client's condition has changed, evidenced by the onset of projectile vomiting and a dilated, non-reactive left pupil, both signs of potential increased ICP and possible brain herniation. A repeat CT scan will help identify any new or worsening intracranial pathology such as bleeding, swelling, or other changes that were not present initially. Timely imaging is essential for appropriate management and to guide further treatment decisions. Choice C rationale Inserting a second large bore IV catheter is vital for ensuring rapid access for fluids, medications, and possible blood products in the event of an acute deterioration. This is especially important in a neurologically unstable client. Having multiple IV access points allows for efficient administration of necessary treatments without delay, which can be crucial in managing worsening intracranial conditions and other emergent needs. Choice D rationale While applying artificial tear drops to the left eye might seem beneficial for preventing corneal dryness in a client who cannot blink, it does not address the acute neurological concerns indicated by the pupil changes and vomiting. This intervention is more supportive rather than urgent or diagnostic. The primary focus should be on identifying and managing the underlying cause of the client's deterioration, not on symptom management alone. Choice E rationale Repeating the Glasgow coma assessment is necessary to monitor any changes in the client's neurological status. Regular assessment helps track the progression or improvement of the client’s condition, guiding clinical decisions. The change in pupil response and vomiting suggests potential worsening, necessitating continuous and frequent reassessments. Prompt detection of deterioration can lead to quicker intervention and potentially better outcomes.
