A 4-year-old child is receiving amoxicillin (Amoxil) to treat otitis media and is in the clinic for a well-child checkup on the last day of antibiotic therapy. The provider orders varicella (Varivax); mumps, measles, and rubella (MMR); inactivated polio (IPV); and diphtheria, tetanus, and acellular pertussis (DTaP) vaccines to be given. Which action by the nurse is correct?

Correct Answer: A

Rationale: Antibiotics like amoxicillin don’t interfere with vaccine efficacy or safety, so all vaccines (MMR, Varivax, IPV, DTaP) can be administered as ordered at the 4-6 year visit (Choice A). Choice B is unnecessary—live vaccines (MMR, Varivax) aren’t affected by antibiotics. Choice C is overly cautious, and Choice D (aspirin) is inappropriate due to Reye’s syndrome risk.

Correct Answer: C

Rationale: Rolling over occurs at 2-6 months, the earliest motor milestone listed (AAP). Crawling (6-12 months), walking (12-18 months), and speaking (words, 12 months) follow later, making Choice C correct.

Correct Answer: C

Rationale: Sickle cell anemia causes sickle cell crises (vaso-occlusive events) due to RBC sickling, per CDC. Choices A, B, and D are distinct conditions, not direct complications.

Correct Answer: C

Rationale: Monitoring vital signs assesses stability in intussusception, a priority before interventions (AAP). Pain meds (Choice A) and surgery prep (Choice B) follow; liquids (Choice D) are contraindicated.

Correct Answer: C

Rationale: A favorite toy reduces anxiety in toddlers (1-3 years) by providing comfort (AAP). Other choices are inappropriate or impractical.
