The nurse is caring for a patient following a craniectomy and left anterior fossae incision who has a nursing diagnosis of impaired physical mobility related to decreased level of consciousness and weakness. Which of the following is an appropriate nursing intervention?
- A. Position the bed flat and log roll the patient.
- B. Cluster nursing activities to allow longer rest periods.
- C. Turn and reposition the patient side to side every 2 hours.
- D. Perform range-of-motion ( ROM) exercises every 4 hours.
Correct Answer: D
Rationale: ROM exercises will help to prevent the complications of immobility. Patients with anterior craniotomies are positioned with the head elevated. The patient with a craniectomy should not be turned to the operative side. When the patient is weak, clustering nursing activities may lead to more fatigue and weakness.

The nurse is assessing a patient who is unconscious and applies a painful stimulus to the nail beds. The patient responds with internal rotation, adduction, and flexion of the arms. Which of the following terms should the nurse use when documenting the findings?
- A. Flexion withdrawal
- B. Localization of pain
- C. Decorticate posturing
- D. Decerebrate posturing
Correct Answer: C
Rationale: Internal rotation, adduction, and flexion of the arms in an unconscious patient is documented as decorticate posturing. Extension of the arms and legs is decerebrate posturing. Because the flexion is generalized, it does not indicate localization of pain or flexion withdrawal.
A patient who is unconscious has a nursing diagnosis of ineffective cerebral tissue perfusion related to cerebral tissue swelling. Which of the following nursing interventions should be included in the plan of care?
- A. Keep the head of the bed elevated to 30 degrees.
- B. Position the patient with the knees and hips flexed.
- C. Encourage coughing and deep breathing to improve oxygenation.
- D. Cluster nursing interventions to provide uninterrupted rest periods.
Correct Answer: A
Rationale: The patient with increased intracranial pressure (ICP) should be maintained in the head-up position to help reduce ICP. Flexion of the hips and knees increases abdominal pressure, which increases ICP. Because the stimulation associated with nursing interventions increases ICP, clustering interventions will progressively elevate ICP. Coughing increases intrathoracic pressure and ICP.
The nurse is caring for a patient with possible cerebral edema who has a serum sodium level of 115 mmol/L, a decreasing level of consciousness (LOC), and has a headache. Which of the following prescribed interventions should the nurse implement first?
- A. Draw blood for arterial blood gases (ABGs).
- B. Administer 5% hypertonic saline intravenously.
- C. Administer acetaminophen 650 mg orally.
- D. Send patient for computed tomography (CT) of the head.
Correct Answer: B
Rationale: The patient's low sodium indicates that hyponatremia may be causing the cerebral edema, and the nurse's first action should be to correct the low sodium level. Acetaminophen will have minimal effect on the headache because it is caused by cerebral edema and increased intracranial pressure (ICP). Drawing ABGs and obtaining a CT scan may add some useful information, but the low sodium level may lead to seizures unless it is addressed quickly.
A patient who is suspected of having an epidural hematoma is admitted to the emergency department. Which of the following actions should the nurse plan to take?
- A. Administer IV furosemide
- B. Initiate high-dose barbiturate therapy
- C. Type and crossmatch for blood transfusion
- D. Prepare the patient for immediate craniotomy.
Correct Answer: D
Rationale: The principal treatment for epidural hematoma is rapid surgery to remove the hematoma and prevent hematoma. If intracranial pressure (ICP) is elevated after surgery, furosemide or high-dose barbiturate therapy may be needed, but these will not be of benefit unless the hematoma is removed. Minimal blood loss occurs with head injuries, and transfusion is usually not necessary.
The nurse is admitting a patient who has a tumour of the right frontal lobe. Which of the following findings should the nurse expect to observe?
- A. Judgement changes
- B. Expressive aphasia
- C. Right-sided weakness
- D. Difficulty swallowing
Correct Answer: A
Rationale: The frontal lobes control intellectual activities such as judgement. Speech is controlled in the parietal lobe. Weakness and hemiplegia occur on the contralateral side from the tumour. Swallowing is controlled by the brain stem.
