An acute care nurse receives shift report for a client who has increased intracranial pressure. The nurse is told that the client demonstrates decorticate posturing. Which of the following findings should the nurse expect to observe when assessing the client?
Extension of the arms
External rotation of the lower extremities
Pronation of the hands
Plantar flexion of the legs
The Correct Answer is D
- A) Extension of the arms is incorrect because decorticate posturing is characterized by flexion into the body, not extension away from it.
- B) External rotation of the lower extremities is not associated with decorticate posturing, which involves movements primarily of the upper extremities.
- C) Pronation of the hands is incorrect as decorticate posturing typically involves flexion of the arms, wrists, and fingers into the chest.
- D) Plantar flexion of the legs is correct because decorticate posturing includes internal rotation and flexion of the arms and wrists, with the legs extended and feet plantar flexed.

Correct Answer is C
Explanation
A. Start a labetalol drip to keep BP less than 140/90 mm Hg: This order is appropriate because it aims to lower the patient's blood pressure to a target range recommended for acute ischemic stroke management.
B. Keep the head of the bed elevated at least 30 degrees: This intervention is part of stroke management to prevent aspiration and improve cerebral perfusion.
C. Begin tissue plasminogen activator (tPA) intravenously per protocol: The nurse should question this order because tissue plasminogen activator (tPA) is contraindicated in patients with stroke who have had symptoms for more than 3 hours or have unknown time of onset, as in this case where the patient has been aphasic for 3 hours. Administering tPA in this situation could increase the risk of bleeding complications without providing benefit.
D. Infuse normal saline intravenously at 75 mL/hr: This order is appropriate for maintaining hydration and intravascular volume in the acute care setting.
Correct Answer is D
Explanation
A. The patient has dysphasia: Dysphasia (difficulty with speech) is a common symptom of stroke but does not contraindicate the use of aspirin for acute ischemic stroke management. Aspirin is routinely administered in the acute phase of ischemic stroke to prevent further clot formation.
B. The patient has atrial fibrillation: Atrial fibrillation increases the risk of embolic strokes, and aspirin may be used for stroke prevention in certain cases. However, the presence of atrial fibrillation alone does not indicate a contraindication to aspirin administration in the acute setting of a suspected stroke.
C. The patient has a history of brief episodes of right-sided hemiplegia: A history of transient ischemic attacks (TIAs) or brief episodes of hemiplegia suggests a risk factor for stroke but does not necessarily contraindicate the use of aspirin in the acute phase of stroke
management. Aspirin is commonly used for secondary prevention after TIAs or minor strokes.
D. The patient reports that symptoms began with a severe headache: Severe headache as the initial symptom of stroke raises concerns about a possible hemorrhagic stroke rather than an ischemic stroke. Administration of aspirin in the setting of a hemorrhagic stroke can worsen bleeding and increase morbidity and mortality. Therefore, the nurse should consult with the healthcare provider before giving aspirin to determine the appropriate course of action based on the patient's presentation and diagnostic evaluation.
