A nurse is caring for a child in an urgent care clinic. Select the 3 findings that require immediate follow-up.

A. While the child reports headache pain, pain level alone is not immediately life-threatening. Pain should be addressed, but the priority findings are those indicating systemic instability or risk of complications. B. The child’s temperature increased from 39.9°C (103°F) to 40°C (104°F) in 2 hours, indicating progressive febrile response. Combined with stiff neck, photophobia, and altered perfusion, this could signal serious bacterial infection, such as meningitis or sepsis, requiring immediate evaluation and intervention. C. Respiratory rate remains 16/min, which is within normal range for school-age children (12–20/min). Although oxygen saturation dropped to 90%, the primary issue is systemic infection and hypotension rather than the respiratory rate itself. D. The abdomen is rounded, soft, and non-tender with hyperactive bowel sounds. There are no acute abdominal findings that require immediate follow-up in this context. E. The child has WBC 17,000/mm³, indicating leukocytosis, which reflects infection or inflammation. Hemoglobin and hematocrit are slightly low, suggesting mild anemia, and these lab abnormalities, combined with vital sign changes, support the need for urgent medical assessment. F. Electrolytes reveal magnesium slightly above normal (1.9 mEq/L) and phosphate slightly low (3.5 mg/dL). While these are mild deviations, in the context of rapid clinical deterioration, hypotension, and infection risk, they warrant immediate follow-up to prevent complications such as cardiac or neurologic effects.
