A nurse is assessing a child who has new onset varicella. Which of the following findings should the nurse expect?
White nits on the hair shaft near the child's scalp
Pruritic vesicles with erythematous base on the child's face
Discolored pruritic warts on the child's feet and ankles
Koplik spots with blue-white centers in the child's mouth
The Correct Answer is B
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.

Correct Answer is A
Explanation
Choice A reason: Changing clothes after working in the field is an evidence-based practice to reduce pesticide exposure. Pesticide residues can cling to clothing and cause prolonged skin contact or contaminate the home environment. This makes option A the correct answer.
Choice B reason: Applying petroleum jelly to the nostrils does not prevent pesticide inhalation. Proper protective equipment such as masks or respirators is required to reduce inhalation risk. This option is incorrect.
Choice C reason: Wiping fruits and vegetables with a dry cloth is insufficient to remove pesticide residues. Washing thoroughly with water is necessary to reduce ingestion risk. This option is incorrect.
Choice D reason: Storing protective equipment in a vehicle exposes it to heat and contamination, reducing its effectiveness. Equipment should be stored in a clean, dry, and safe environment. This option is incorrect.
Correct Answer is B
Explanation
Choice A reason: Heat should not be applied during the first 24 hours after a sprain because it increases blood flow and swelling. Cold therapy (ice packs) is recommended initially to reduce inflammation. This option is incorrect.
Choice B reason: Wrapping the affected extremity with a compression dressing is part of the RICE protocol (Rest, Ice, Compression, Elevation), which is the standard treatment for sprains. Compression helps reduce swelling and provides support. This is the correct answer.
Choice C reason: Acetaminophen is effective for pain but does not reduce inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are preferred for managing both pain and inflammation in sprains. Therefore, this option is incorrect.
Choice D reason: Advising the client to begin walking 4 hours after the injury is unsafe. Early ambulation can worsen tissue damage and swelling. Rest is recommended initially, followed by gradual weight-bearing as tolerated. This option is incorrect.
