Final answer:
The PNP should initiate early intervention services for the 2-year-old with a speech delay after normal motor and cognitive screenings and a passed hearing test. Further evaluation by a developmental specialist may follow if needed.
Step-by-step explanation:
If the Pediatric Nurse Practitioner (PNP) is evaluating a 2-year-old child with a documented speech delay, whose motor skills and cognition are normal and who has passed a recent hearing test, the next appropriate step would be to Initiate early intervention services (Option C). Early intervention services are designed to provide support and therapy to children with developmental delays as early as possible. These services may include speech therapy, which can help the child improve communication skills.
If there continues to be lack of progress in the child's speech development or if other concerns arise, referral to a developmental specialist for a more in-depth evaluation may become necessary (Option A). It's generally not necessary to reassure the parents and simply monitor progress without intervention (Option B) or order a repeat hearing test (Option D) if the screenings and the initial hearing test have already been conducted and show normal results.
