The nurse is teaching the parents of a child with varicella about the disorder.
The nurse determines that the teaching was successful when the parents state which of the following?

Choice A rationale

Applying warm water to pruritic (itchy) skin, especially with a viral exanthem like varicella, can cause vasodilation and increased blood flow to the area, which may intensify the itching sensation rather than providing relief. Cool or tepid baths with oatmeal preparations are generally more soothing because they reduce skin temperature and inflammation, helping to calm the nerve endings responsible for the itch.

Choice B rationale

Salt solutions, particularly when concentrated, can be irritating and drying to delicate mucous membranes like the oral mucosa, potentially causing pain and delaying the healing of vesicular lesions caused by the varicella virus. Gentle, plain water rinses or non-irritating, topical anesthetic mouthwashes (if prescribed and appropriate for the child's age) are better alternatives for comfort and maintaining oral hygiene.

Choice C rationale

Aspirin (acetylsalicylic acid) is strictly contraindicated for fever management in children with varicella (chickenpox) or other viral illnesses due to the significant risk of developing Reye syndrome, a rare but severe illness causing acute encephalopathy and liver damage. Acetaminophen (paracetamol) or ibuprofen are the standard, safe antipyretic choices for managing fever in children with varicella.

Choice D rationale

Scratching the varicella lesions must be strictly avoided as it can break the skin barrier, leading to secondary bacterial infections like cellulitis or impetigo, which require antibiotic treatment. Furthermore, excoriation from scratching significantly increases the risk of permanent scarring (pitting) after the lesions have healed, making this a critical instruction for parents.

Choice A rationale

This response inappropriately questions the mother's recollection or honesty regarding her son's immunization status, potentially damaging the therapeutic relationship and trust. While verifying the immunization record is essential, the initial response should prioritize validating the parent's frustration and offering a scientifically sound explanation of vaccine efficacy. The focus should be on education and support, not interrogation, to ensure collaborative care and open communication with the family.

Choice B rationale

Questioning the physician's adherence to the standard immunization schedule is confrontational and unprofessional, potentially leading the parent to distrust the primary care provider. The nurse must maintain a professional stance, focusing on providing accurate, non-judgmental information about vaccine characteristics. It is highly unlikely a standard physician would knowingly deviate from well-established public health guidelines without cause.

Choice C rationale

Acknowledging the mother's frustration is good communication, but immediately asking where the immunizations were performed is irrelevant to the central question of why a vaccinated child contracted the disease. The location of vaccination does not typically affect the vaccine's efficacy. The priority is to educate the parent on the biological reality of vaccine effectiveness rates and the possibility of primary vaccine failure.

Choice D rationale

This response is the most therapeutic and accurate, validating the parent's concern while providing a correct scientific explanation. While highly effective, vaccines like the MMR (Measles, Mumps, Rubella) vaccine do not guarantee 100 percent immunity (primary vaccine failure) in all individuals, meaning a small percentage of fully vaccinated people may still contract the disease. This is due to individual variations in immune response.
