A nurse is reinforcing teaching with a group of adolescents about safety. Which of the following information should the nurse include in the teaching?

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.

Choice A rationale:
Urticaria, commonly known as hives, is a skin rash characterized by raised, red, and itchy welts that can vary in size and shape. It is a classic manifestation of an allergic reaction. Allergic reactions can occur in response to medications like clindamycin. Urticaria is a result of histamine release and can range from mild to severe, with itching being a prominent symptom. The appearance of urticaria in a child taking clindamycin suggests a potential allergic reaction to the medication.
Choice B rationale:
Conjunctivitis, or pink eye, is inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and lines the inner surface of the eyelids. While conjunctivitis can be associated with allergies, it is not a typical sign of an allergic reaction to clindamycin. Conjunctivitis is more commonly associated with eye irritation, redness, and discharge.
Choice C rationale:
A temperature of 38°C (100.4°F) alone is not a definitive sign of an allergic reaction to medication. Fever can be caused by a variety of factors, including infections, inflammatory processes, and other non-allergic reactions. While fever can be a symptom of an allergic reaction in some cases, it is not as specific as urticaria in indicating an allergic response.
Choice D rationale:
Cool extremities are not a classic sign of an allergic reaction to medication. Allergic reactions typically involve skin manifestations like hives, itching, and redness. Cool extremities might suggest poor peripheral circulation or decreased blood flow to the extremities, but they are not directly indicative of an allergic reaction to clindamycin.
