A nurse is preparing to obtain a blood specimen from a preschooler. Which of the following actions should the nurse perform?

Rationale for Correct Choices:

• Pain medication: Pain control is a primary concern in fracture management, especially in pediatric clients. This child reports a pain score of 4/10, indicating discomfort. Administering pain medication will reduce suffering and help prevent complications such as anxiety or guarding, which may impair healing.
• Limb immobilization: Immobilization stabilizes the fracture site and prevents further injury to soft tissues or neurovascular structures. With a nondisplaced fracture of both radius and ulna, the nurse should expect a splint or cast order to limit movement and aid in bone alignment and healing.

Rationale for Incorrect Choices:

• Bed rest: Bed rest is not required for isolated upper limb fractures, particularly when the child is developmentally appropriate, alert, and ambulatory. Encouraging mobility is important to reduce the risk of complications like deconditioning or thromboembolism.
• Surgical consultation: A nondisplaced fracture typically does not require surgical intervention unless complications develop. Surgical consultation is more often necessary for open, displaced, or unstable fractures that require reduction or fixation.
• Antibiotics: There are no signs of systemic or localized infection. The child has a superficial knee abrasion but no open fracture or wound that would necessitate prophylactic antibiotics. Therefore, antibiotic use is not indicated in this situation.

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.
