A school nurse is examining a third-grade student complaining of a small lump on her head. After parting the hair, it is evident that a tick has embedded into the scalp. Which nursing intervention should the school nurse take?

A. Frequent handwashing is critical in preventing the spread of infections, especially when one person in the household is ill with gastroenteritis. This practice indicates good hygiene and care for the client.
B. Drinking an electrolyte solution can help the spouse stay hydrated, especially when experiencing frequent loose stools due to gastroenteritis. Staying hydrated is essential for recovery.
C. If the spouse is actively preparing food for the client while having gastroenteritis, there is a risk of contaminating the food, which could lead to the client becoming ill. The client may be more vulnerable to infections, particularly following a stroke, and it is crucial to prevent exposure to any pathogens.
D. This observation is a good practice as it helps prevent the spread of germs. Using separate personal items, like a toothbrush and toothpaste, can minimize the risk of transmitting infections.

A. Topical corticosteroids are not typically used for impetigo, as it's a bacterial infection.
B. Impetigo is highly contagious, so contact precautions are essential to prevent the spread of infection. This includes wearing gloves and a gown when providing direct care, and using dedicated equipment for the child.
C. A wood lamp is used to examine the skin for fungal infections, not bacterial infections like impetigo.
D. Impetigo typically doesn't require dressings. If dressings are used, they should be removed gently to avoid further skin damage.
