A nurse is caring for a client who experienced an acute ischemic stroke 4 hours ago and is receiving tissue plasminogen activator (tPA). Which nursing intervention is the highest priority during the first 24 hours post-tPA administration?

Frequent neurological assessments and monitoring for intracranial bleeding are highest priority due to tPA's risk of life-threatening hemorrhagic complications. Other interventions (mobilization, glucose monitoring, anticoagulants) are important but secondary in the first 24 hours.

Understanding the Priority: Post-tPA Monitoring for Hemorrhagic Transformation

The administration of tissue plasminogen activator (tPA) for an acute ischemic stroke is a critical, time-sensitive intervention designed to restore cerebral blood flow by dissolving the occluding clot. However, the most significant and life-threatening complication during the immediate post-thrombolysis phase is hemorrhagic transformation (HT), particularly symptomatic intracranial hemorrhage (sICH). As noted in the comprehensive review by Yang et al., sICH "significantly increases the risk of death and disability" and is the primary factor limiting the therapeutic benefit of thrombolysis ^[1]. Therefore, the nursing priority is not to prevent secondary complications like contractures or to manage blood glucose, but to detect the earliest signs of this catastrophic bleeding.

Why Frequent Neurological Assessments Are the Highest Priority

The clinical window for intervention in sICH is narrow. The review emphasizes the importance of "early identification" as a cornerstone of integrated nursing management ^[1]. A subtle change in neurological status is often the first and only indicator of an evolving intracranial bleed. By performing frequent, standardized neurological assessments—such as monitoring the patient's level of consciousness, pupillary response, motor strength, and speech—the nurse acts as the primary surveillance system. A deterioration in the National Institutes of Health Stroke Scale (NIHSS) score, a sudden severe headache, or an acute rise in blood pressure can signal hemorrhagic transformation before it becomes irreversible. This aligns directly with the review's focus on systematic early identification strategies to improve patient outcomes ^[1].

Analyzing the Other Options in the Context of the Acute Phase

- Option 1: Early Mobilization and Range-of-Motion Exercises: While rehabilitation is crucial for long-term stroke recovery, aggressive early mobilization in the first 24 hours post-thrombolysis is contraindicated. The patient's blood-brain barrier is fragile, and cerebral autoregulation may be impaired. Sudden changes in positioning can disrupt hemodynamic stability and theoretically increase the risk of hemorrhagic transformation. The immediate priority is maintaining cerebral perfusion and stability, not preventing contractures.

- Option 2: Blood Glucose Monitoring: Hyperglycemia is indeed associated with worse outcomes in ischemic stroke and can exacerbate hemorrhagic conversion. However, checking blood glucose every 4 hours is a standard, scheduled intervention. It does not address the immediate, moment-to-moment threat of acute neurological deterioration from an intracranial bleed. Managing physiological parameters is important but secondary to direct neurological surveillance.

- Option 4: Administering Anticoagulants: This action is strictly contraindicated in the first 24 hours after tPA administration. The patient is in a profound fibrinolytic and anticoagulated state from the tPA itself. Adding anticoagulants or antiplatelet agents during this critical period would exponentially increase the risk of sICH, the very complication the nurse is vigilantly trying to detect. The standard of care mandates a 24-hour post-thrombolysis waiting period, with a follow-up CT scan to rule out hemorrhage, before any antithrombotic therapy is initiated.

The nurse's role in the first 24 hours is to function as a continuous clinical monitor, translating the principle of "early identification" from the literature into bedside practice. Serial neurological checks provide the real-time data necessary to detect the earliest signs of hemorrhagic transformation, allowing for immediate life-saving interventions such as stopping the infusion, obtaining emergency imaging, and preparing for potential reversal of coagulopathy ^[1].
