A nurse is assisting with the care of a school-age child who has shigella. Which of the following actions should the nurse take?

Choice A rationale: Maintaining oral rehydration therapy is a crucial nursing action when caring for a child with shigella, which is a bacterial infection that causes severe diarrhea. Oral rehydration therapy helps prevent dehydration and electrolyte imbalances caused by fluid loss from diarrhea. It involves giving the child oral rehydration solutions containing electrolytes and fluids to replace those lost through diarrhea. Choice B rationale: Providing a diet high in sodium is not recommended for a child with shigella. Shigella is associated with diarrhea and gastrointestinal symptoms, and a high-sodium diet can worsen fluid imbalances and dehydration. Choice C rationale: Shigella is a bacterial infection, not a viral infection, so administering antiviral medication would not be effective or appropriate. Antiviral medications are used to treat viral infections, not bacterial ones like shigella. Choice D rationale: Giving antidiarrheal agents every 4 hours is not recommended for a child with shigella. Antidiarrheal agents can slow down the gastrointestinal tract and inhibit the body's natural mechanism for expelling harmful substances, such as bacteria. It's important to allow the body to eliminate the bacteria and toxins causing the infection through diarrhea, while simultaneously providing rehydration support.
