A nurse is caring for a client who is receiving morphine intravenously. Which of the following findings indicates the client is experiencing morphine toxicity?

Rationale:

A. Call in additional medical-surgical unit nursing care staff: The initial priority during a mass casualty event is to maximize available resources and free up beds by discharging stable clients. Staffing adjustments come after determining how to expand capacity.

B. Act as a liaison between the facility and the media: This role falls under the responsibilities of public relations or designated administrative personnel. Nurses should focus on patient care and operational tasks relevant to their scope during a crisis.

C. Determine the medical needs of incoming clients through the emergency department: Triage of incoming casualties is performed by designated emergency department staff. Nurses from other units typically assist by creating space or relocating stable clients.

D. Recommend to the provider specific acute care clients for discharge: Identifying stable clients who can be safely discharged allows beds and resources to be allocated to incoming critical cases. This is an appropriate and immediate nursing response during mass casualty.

Rationale for Correct Choices:

• Reye's syndrome: The toddler's worsening condition including vomiting, lethargy, and altered consciousness after a viral illness (influenza A) is consistent with Reye’s syndrome, which affects the liver and brain. The progression from mild viral symptoms to neurologic decline without respiratory compromise further supports this diagnosis.
• Aspirin administration: Giving aspirin during a viral illness in children is a well-known precipitant of Reye’s syndrome. The caregivers' report of alternating aspirin with acetaminophen confirms the exposure necessary to trigger the condition in a susceptible child.

Rationale for Incorrect Choices:

• Gastroenteritis: While vomiting is a feature of gastroenteritis, the absence of diarrhea and the presence of neurologic changes like lethargy and poor responsiveness make this unlikely. Additionally, the clear vomiting and lack of fluid intake without prior GI focus suggest another etiology.
• Bronchitis: Bronchitis typically causes a productive cough with wheezing, chest discomfort, and possible fever. This toddler's lungs are clear with a nonproductive cough, and neurologic signs are not typical of bronchitis.
• Acetaminophen administration: Acetaminophen is safe and commonly used to treat fever in toddlers. It is not associated with hepatic encephalopathy or neurologic complications seen in this scenario.
• Oseltamivir administration: Though oseltamivir may cause gastrointestinal side effects like nausea or vomiting, it does not explain the altered mental status and lethargy. It is also unlikely to cause such a significant clinical deterioration on its own.
