Final answer:
A 7-year-old child should be able to speak in full sentences but may have difficulty understanding concepts like "half past" in reference to time.
Step-by-step explanation:
In a conversation with a 7-year-old child, the nurse should expect the child to be able to speak in full sentences. Therefore, option a) is not the correct answer. However, it is normal for a child of this age to have difficulty understanding concepts like "half past" in reference to time, so option b) is a potential answer choice. Option c) is incorrect as a 7-year-old child is still developing their language skills and may not be able to carry on an adult conversation. Option d) is also incorrect as fascination with bathroom language is not a typical expectation of a child's language development at this age.
