After completing a thorough neurological and physical assessment of a patient who is admitted for a suspected stroke, the medical-surgical nurse anticipates the next step in the immediate care of this patient will include:

1. A

   Obtaining a CT scan of the head without contrast

2. B

   Administering tissue plasminogen activator

3. C

   Obtaining a neurosurgical consultation

4. D

   Preparing for carotid Doppler ultrasonography

Appeared in: UPUMS Nsg.Officer-2024

Explanation

• The immediate priority after initial assessment of a suspected stroke is to differentiate between an ischemic and a hemorrhagic event.
• A noncontrast CT scan of the head is the fastest and most reliable method to rule out intracranial hemorrhage.
• This diagnostic step is mandatory before considering thrombolytic therapy (like tPA), as administering it during a hemorrhagic stroke is life-threatening.
• Clinical findings alone are not sufficient to reliably distinguish between ischemic and hemorrhagic stroke, making imaging essential.

Why Other Options Were Wrong

• Option B: Administering tissue plasminogen activator (tPA) is a treatment for ischemic stroke, not a diagnostic step. It is absolutely contraindicated until a hemorrhagic stroke has been ruled out by a CT scan, as it would cause severe, potentially fatal bleeding.
• Option C: A neurosurgical consultation is not the immediate next step for all suspected strokes. It is only indicated after imaging confirms a condition requiring surgical intervention, such as a large intracerebral hemorrhage, a subarachnoid hemorrhage, or significant brain swelling (edema).
• Option D: Carotid Doppler ultrasonography is part of the secondary workup for an ischemic stroke. Its purpose is to identify the underlying cause (e.g., carotid artery stenosis) to guide long-term prevention strategies.

Clinical Relevance

• Nursing practice connection: Safe nursing care depends on performing Acute Stroke Management and Diagnostic Priorities in the correct sequence, documenting the action clearly, and monitoring for the expected response.
• The mantra in stroke care is "Time is Brain." Every minute of delay results in the loss of millions of neurons. The goal is to have a noncontrast CT scan performed and interpreted within 25 minutes of the patient's arrival in the emergency department.
• A nurse's role is critical in expediting this process by anticipating the need for the CT scan, preparing the patient, and ensuring rapid transport to the imaging suite.
• What if? The patient awakens with stroke symptoms. In this case, the 'last known well' time is when they went to sleep. This often places them outside the window for tPA, but the CT scan is still the immediate priority to rule out hemorrhage and guide other management, such as potential mechanical thrombectomy.

How to Approach the Question

• First, identify the clinical situation: a patient with a 'suspected' stroke. This means the diagnosis is not yet confirmed.
• Recognize that the most critical initial question in stroke care is differentiating between a bleed (hemorrhagic) and a clot (ischemic), as their treatments are opposite and giving the wrong one is dangerous.
• Evaluate the options based on this priority. Ask yourself: Which of these actions answers the 'bleed vs. clot' question?
• Option A (CT scan) is a diagnostic test to visualize the brain and detect bleeding.
• Options B (tPA), C (neurosurgery), and D (Doppler) are either treatments or secondary investigations that depend on the initial diagnosis.
• Therefore, the diagnostic test (CT scan) must precede any treatment or further investigation.

Concept Tested & Keywords

• Concept Tested: Acute Stroke Management and Diagnostic Priorities
• Stem keywords: suspected stroke, neurological assessment, physical assessment, immediate care
• Lead-in keywords: next step
• Clinical cues: The patient is admitted for a 'suspected' stroke, indicating the diagnosis is not yet confirmed, making diagnostic imaging the top priority.
• Negative lead-in flag: false
