old infant with a positive Moro reflex is a finding that requires further intervention

2. A nurse is reinforcing teaching a parent of a child who has a fracture of the epiphyseal plate. Which of thefollowing
is an appropriate statement by the nurse?

detected and treated rapidly.
C. “Bone marrow can be lost though the fracture.”
Rationale: The epiphyseal plate is the cartilage growth plate. Therefore, bone marrow is notlost
through this type of fracture.

throughout the day are seen with severe persistent asthma.
Daytime symptoms occur more than twice a week is correct. A child with mild
