A nurse is assessing a 3-year-old child and suspects the child may have a developmental delay. Which of the following actions is a priority for the nurse to take?

Identifying developmental delays in toddlers requires the application of pediatric growth benchmarks and the nursing process. Prioritization hinges on interdisciplinary communication to validate clinical observations before initiating specific interventions, ensuring the diagnostic process is medically accurate and collaborative. Choice A rationale Effective clinical practice necessitates that assessment data are verified by the primary provider to establish a formal diagnosis. This communication ensures that the medical plan of care is adjusted based on accurate, professional interpretation of developmental milestones. Choice B rationale Social work referrals for early intervention are critical secondary actions once a delay is formally identified. While these services support long-term outcomes, they cannot precede the medical validation and formal referral process initiated by the healthcare team. Choice C rationale Education is premature before a definitive diagnosis is made by the provider. Providing specific information about delays before confirmation may cause unnecessary parental anxiety and violates the sequence of the nursing process regarding assessment and diagnosis. Choice D rationale Support groups provide emotional and community resources for families dealing with established diagnoses. However, this is a supportive intervention rather than a clinical priority during the initial assessment phase when diagnostic certainty is still being pursued.
