A nurse is assessing a child who has new onset varicella. Which of the following findings should the nurse expect?

Choice A reason: White nits on the hair shaft indicate pediculosis capitis (head lice), not varicella. This finding is unrelated to viral infection and represents a parasitic infestation. Choice B reason: Pruritic vesicles with an erythematous base are the hallmark of varicella (chickenpox). The rash typically begins on the face and trunk, progressing to limbs, and appears in successive crops. The vesicles are intensely itchy and evolve into pustules and crusts. Choice C reason: Discolored pruritic warts on the feet and ankles are characteristic of human papillomavirus (HPV), not varicella. Warts are firm growths, not vesicular lesions. Choice D reason: Koplik spots are pathognomonic for measles, not varicella. They appear as small blue-white lesions on the buccal mucosa before the measles rash develops.
