Nokea
The nurse is admitting a patient with a basal skull fracture and notes clear drainage from the patient's nose. Which of these admission orders should the nurse question?
- A. Insert nasogastric tube
- B. Turn patient every 2 hours.
- C. Keep the head of bed elevated.
- D. Apply cold packs for facial bruising.
Correct Answer: A
Rationale: Rhinorrhea may indicate a dural tear with cerebrospinal fluid (CSF) leakage, and insertion of a nasogastric tube will increase the risk for infections such as meningitis. Turning the patient, elevating the head, and applying cold packs are appropriate orders.

The nurse is assessing a patient with a head injury. Which of the following assessments should the nurse complete first?
- A. Obtain oxygen saturation.
- B. Check pupil reaction to light.
- C. Palpate the head for hematoma.
- D. Assess Glasgow Coma Scale (GCS).
Correct Answer: A
Rationale: Airway patency and breathing are the most vital functions and should be assessed first. The neurological assessments should be accomplished next and the health and medication history last.
The nurse is suctioning a patient with a traumatic head injury and notes that the intracranial pressure has increased from 14 to 16 mm Hg. Which of the following actions should the nurse take first?
- A. Document the increase in intracranial pressure.
- B. Assume that the patient's neck is not in a flexed position.
- C. Notify the health care provider about the change in pressure.
- D. Increase the rate of the prescribed propofol infusion.
Correct Answer: B
Rationale: Since suctioning will cause a transient increase in intracranial pressure, the nurse should initially check for other factors that might be contributing to the increase and observe the patient for a few minutes. Documentation is needed, but this is not the first action. There is no need to notify the health care provider about this expected reaction to suctioning. Propofol is used to control patient anxiety or agitation, there is no indication that anxiety has contributed to the increase in intracranial pressure.
The nurse is caring for a patient with increased intracranial pressure (IICP). Which of the following are late signs of IICP? (Select all that apply.)
- A. Unilateral hemiparesis
- B. Papilledema
- C. Decorticate posturing
- D. Decerebrate posturing
- E. Hyperthermia
Correct Answer: C,D,E
Rationale: Late signs of IICP include decerebrate posturing, decorticate posturing, and hyperthermia. Unilateral hemiparesis and papilledema are early signs when the compensatory mechanism is intact.
Which of the following information about a patient who is hospitalized after a traumatic brain injury requires the most rapid action by the nurse?
- A. Intracranial pressure of 15 mm Hg.
- B. Cerebrospinal fluid (CSF) drainage of 15 mL/hour
- C. Pressure of oxygen in brain tissue (PbtO2) is 14 mm Hg.
- D. Cardiac monitor shows sinus tachycardia, with a heart rate of 126 beats/minute
Correct Answer: C
Rationale: The PbtO2 should be 20-40 mm Hg. Lower levels indicate brain ischemia. An intracranial pressure (ICP) of 15 mm Hg is at the upper limit of normal. CSF is produced at a rate of 20-30 mL/hour. The reason for the sinus tachycardia should be investigated, but the elevated heart rate is not as concerning as the decrease in PbtO2.
The nurse is providing discharge teaching with a patient who has a concussion. Which of the following time frames should the nurse tell the patient to continue to monitor for post-concussion syndrome?
- A. Up to 2 weeks
- B. Up to 4 weeks
- C. Up to 2 months
- D. Up to 6 months
Correct Answer: C
Rationale: Post-concussion syndrome is seen anywhere from 2 weeks to 2 months after the concussion. Symptoms include persistent headache, lethargy, personality and behavioural changes, shortened attention span, decreased short-term memory, and changes in intellectual ability. This syndrome can significantly affect the patient's abilities to perform the activities of daily living.
