A nurse is attending a continuing education course about communicable diseases. The nurse should identify that varicella has which of the following incubation periods?

Choice A rationale
While maintaining a saline-lock can be important for administering medications or fluids, it is not the priority action. The nurse’s priority should be to assess the child’s condition and intervene to prevent complications.
Choice B rationale
A no-salt-added diet may be recommended for some children with acute glomerulonephritis to help manage fluid balance and blood pressure. However, this is not the priority action. The nurse’s priority should be to assess the child’s condition and intervene to prevent complications.
Choice C rationale
This is the correct answer. Checking the child’s weight daily is a priority action because weight changes can indicate fluid retention or loss, which can affect kidney function. Regular weight checks can help guide treatment decisions and monitor the effectiveness of interventions.
Choice D rationale
Educating the parents about potential complications is important, but it is not the priority action. The nurse’s priority should be to assess the child’s condition and intervene to prevent complications.

Choice A rationale
Pediculosis capitis, also known as head lice, is a common condition in children. One of the definitive indications of this condition is the presence of firmly attached white particles on the hair, which are the eggs or “nits” of the lice.
Choice B rationale
While itching and scratching of the head can be a symptom of pediculosis capitis, it is not a definitive indication as it can be caused by other conditions such as dandruff or dermatitis.
Choice C rationale
Patchy areas of hair loss are not typically associated with pediculosis capitis. They could indicate a different condition, such as alopecia areata or tinea capitis.
Choice D rationale
Thick yellow-crusted lesions on a red base are not a symptom of pediculosis capitis. This description is more consistent with impetigo, a bacterial skin infection.
