A nurse is preparing to initiate IV therapy for an older adult client. Which of the following actions should the nurse plan to take?

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.

Rationale:

A. The person holding financial power of attorney will make health care decisions based on the client's advance directives: A financial power of attorney manages financial matters, not health care decisions. A separate designation such as a health care proxy or medical power of attorney is needed for making medical decisions.

B. The client has the right to refuse medical treatment, even if health care providers recommend it: Under the Patient Self-Determination Act (PSDA), clients have the legal right to make autonomous decisions about their care, including the right to refuse or discontinue treatment, regardless of medical advice.

C. The client's eldest adult child has the right to change advance directives in an end-of-life situation: Advance directives reflect the client’s own decisions. No family member, regardless of birth order, has the legal authority to change them unless specifically authorized as a health care proxy and even then, only if the client is incapacitated.

D. If the client's advance directives are in writing and notarized, the client cannot change it in the future: Clients can revise or revoke advance directives at any time, as long as they remain mentally competent. Notarization does not make the document legally fixed or unchangeable.
