To evaluate the effectiveness of prescribed therapies for a patient with ventilatory failure, which diagnostic test will be most useful to the nurse?

Rationale for Correct Answers:

• Notify the provider: The client’s sudden change in level of consciousness, restlessness, irritability, and new headache after receiving alteplase indicates a potentially serious complication. Immediate notification of the healthcare provider is critical to ensure prompt evaluation, possible imaging, and interventions to prevent further neurological deterioration.
• Increased intracranial pressure: The new neurological symptoms, decreased responsiveness, irritability, and headache, suggest rising intracranial pressure (ICP), likely secondary to cerebral edema following ischemic stroke and thrombolytic therapy. Increased ICP can compromise cerebral perfusion and oxygenation, leading to rapid neurological decline. Early recognition and intervention are essential to prevent permanent damage or herniation.

Rationale for Incorrect Answers:

• Encourage the client to rest quietly: This delays emergency intervention. The symptoms indicate possible intracranial bleeding, not simple fatigue.
• Document the findings and continue routine monitoring: Routine monitoring is inappropriate when there is a sudden neurologic change after thrombolytic therapy. This is not stable, it is a potential life-threatening complication.
• Hypoglycemia: This can cause altered LOC, but there is no evidence in the scenario suggesting low blood glucose. Additionally, the new severe headache strongly suggests increased ICP.
• Anxiety: This does not cause decreased level of consciousness or focal neurologic decline.

A. Sitting in the tripod position: Tripod positioning is a common compensatory mechanism in patients with COPD to maximize diaphragmatic expansion and ease breathing. While it indicates respiratory distress, it is an expected adaptive behavior and not immediately life-threatening.

B. O₂ saturation of 91%: An oxygen saturation of 91% is slightly below normal and should be monitored. In COPD patients, target saturations are often 88–92%, so this finding alone may not require urgent intervention if the patient is otherwise stable.

C. Respiratory rate has decreased from 30 to 10 breaths/min: A sudden drop in respiratory rate in a patient previously tachypneic is highly concerning, as it suggests impending respiratory failure or fatigue of the respiratory muscles. This change indicates inadequate ventilation and CO₂ retention, requiring immediate notification to the healthcare provider for urgent intervention.

D. Bilateral lung crackles: Crackles may indicate fluid overload, infection, or pulmonary edema, which are important to monitor and treat. However, in acute respiratory distress, a decreasing respiratory rate represents a more immediate threat to oxygenation and ventilation, making it the highest priority to report.
