The nurse caring for a 5 month old with viral influenza suspects the development of Reye's syndrome when the child:

Correct Answer: A

Rationale: Effortless vomiting (A) is an early Reye’s syndrome sign post-viral infection, linked to aspirin use. Normal breathing (B), sleeping (C), or rash (D) are not specific. Document: 'The onset of [Reye’s] is effortless vomiting.'

Correct Answer: B

Rationale: Maternal influenza vaccination (Choice B) reduces infant influenza risk up to 3 months via transplacental antibody transfer, with evidence showing significant protection against severe disease. Hepatitis B (Choice A) vaccination protects against chronic infection, not acute infant disease. Measles (Choice C) vaccination isn’t given in pregnancy due to live virus risks. Meningococcal B (Choice D) lacks robust data for infant protection via maternal immunization. Influenza’s proven efficacy makes it the correct choice.

Correct Answer: B

Rationale: At 1 year, children typically need 3-4 feedings daily , including meals and snacks, as they shift to solids with less milk (AAP). 1-2 is inadequate, 5-6 suits younger infants, and 7-8 or 9-10 (D, E) are excessive.

Correct Answer: C

Rationale: C1q deficiency causes SLE-like syndromes without typical autoantibodies due to impaired immune complex clearance (NIAMS). Later complement defects (A-D) lead to infections, not SLE-like features.

Correct Answer: B

Rationale: Aspirin is linked to Reye syndrome in kids with viral infections, causing hepatic and brain issues (CDC). Other drugs (A-D) lack this association.
