Zorluk: Çok zorEstablishing Priorities

A nurse is assessing a client who was admitted 24 hours ago with a severe traumatic brain injury (TBI) following a fall. Based on the principles of prioritization, which of the following assessment findings represent an acute deterioration requiring the nurse to intervene immediately? Select all that apply.

  1. Core body temperature increasing to 102.6°F (39.2°C) over the last hourCevap
  2. Urine output totaling 950 mL of pale urine over the past two hoursCevap
  3. Right pupil measuring 7 mm and completely unresponsive to lightCevap
  4. D
    Glasgow Coma Scale (GCS) score remaining at 9 since the previous shift
  5. E
    Client exhibiting persistent retrograde amnesia regarding the events of the fall

Cevap

The findings requiring immediate intervention are the rapidly increasing core body temperature, the massive urine output (950 mL in 2 hours), and the newly fixed, dilated right pupil.
The correct findings represent acute, unexpected, and life-threatening complications of a traumatic brain injury. A rapidly increasing core temperature significantly raises cerebral metabolic demand and intracranial pressure. A massive urine output indicates the onset of central Diabetes Insipidus, which quickly leads to hypovolemic shock and decreased brain perfusion. A fixed and dilated pupil is an ominous sign of uncal herniation and brainstem compression. All three require immediate life-saving medical intervention.

Adım Adım Çözüm

1
Analyze the client's primary diagnosis (Traumatic Brain Injury) and current timeline (24 hours post-injury).
The client is in the acute phase of recovery, placing them at high risk for secondary brain injuries, increased intracranial pressure (ICP), and endocrine disruptions.
Understanding the timeline helps anticipate potential life-threatening complications versus baseline neurological deficits.
2
Evaluate each assessment finding using the unexpected versus expected and acute versus stable prioritization frameworks.
Hyperthermia, sudden massive polyuria, and a fixed/dilated pupil are unexpected, dynamic deteriorations indicating neurogenic fever, Diabetes Insipidus, and brain herniation. A stable GCS and amnesia are expected or stable baseline findings for this injury.
Prioritization requires identifying signs that signal active physiological deterioration or impending instability.
3
Apply the Airway, Breathing, Circulation (ABC) and severe neurological impairment criteria to the dynamic changes.
The fixed/dilated pupil indicates imminent herniation (brainstem compression); massive polyuria threatens Circulation via hypovolemia; hyperthermia exacerbates ICP. All three are highest priority emergencies.
Life-threatening complications involving massive fluid loss, rising ICP, and brain herniation must be addressed before managing stable or expected neurological deficits.

Anahtar Kavram

When establishing priorities for a client with a traumatic brain injury, the nurse must rapidly differentiate between stable, expected neurological deficits and dynamic, unexpected findings that indicate secondary brain injury, such as increased ICP, herniation, or central endocrine disruption.
