A nurse is caring for a 3-year-old child who was admitted with acute diarrhea and dehydration. Which of the following findings indicates that oral rehydration therapy has been effective?

Choice A reason: A protective environment is a type of isolation precaution that is used for patients who are immunocompromised and at high risk of infection from environmental sources, such as fungi or bacteria. It involves using a private room with positive air pressure, high-efficiency particulate air (HEPA) filtration, and strict hand hygiene. It is not indicated for patients who have measles, as they are the source of infection, not the susceptible host.

Choice B reason: Airborne is a type of isolation precaution that is used for patients who have diseases that are transmitted by small droplets that can remain suspended in the air and travel over long distances, such as tuberculosis, chickenpox, or measles. It involves using a private room with negative air pressure, HEPA filtration, and respiratory protection for health care workers and visitors. It is the appropriate isolation precaution for patients who have measles, as it prevents the spread of the virus to others.

Choice C reason: Contact is a type of isolation precaution that is used for patients who have diseases that are transmitted by direct or indirect contact with the patient or their environment, such as Clostridioides difficile, scabies, or impetigo. It involves using a private room or cohorting with similar patients, wearing gloves and gowns, and using dedicated equipment. It is not indicated for patients who have measles, as the disease is not spread by contact.

Choice D reason: Droplet is a type of isolation precaution that is used for patients who have diseases that are transmitted by large droplets that are generated by coughing, sneezing, or talking, such as influenza, pertussis, or meningitis. It involves using a private room or cohorting with similar patients, wearing a surgical mask, and maintaining a distance of at least 3 feet from the patient. It is not indicated for patients who have measles, as the disease is spread by airborne transmission.

Choice A reason: The child has acute lymphoblastic leukemia (ALL) and is receiving chemotherapy and steroids, which can cause constipation. The nurse should monitor the child's bowel function and provide interventions such as fluids, fiber, and laxatives as prescribed, but this is not an urgent finding.

Choice B reason: The child is in the induction phase of treatment for ALL, which can be stressful and frightening for the child and the family. The child's crying and clinging behavior indicates anxiety and fear, which are normal reactions. The nurse should provide emotional support and education to the child and the guardian, but this is not an urgent finding.

Choice C reason: The child has a fever, which is a common side effect of chemotherapy and steroids. The nurse should assess the child for other signs of infection, administer antipyretics as prescribed, and monitor the child's vital signs, but this is not an urgent finding.

Choice D reason: The child has a double-lumen central line catheter in the left chest wall, which is a potential source of infection. The erythema and purulent drainage at the insertion site indicate that the child has a local infection, which can spread to the bloodstream and cause sepsis. This is a life-threatening complication that requires immediate attention and treatment. The nurse should report this finding to the provider, obtain blood cultures, and administer antibiotics as prescribed.
