Final answer:
The correct statement indicating the need for further instruction regarding clubfoot treatment is option D, where the mother says she needs to come to the clinic every week with her child for the casting.
Step-by-step explanation:
The correct answer is D."I need to come to the clinic every week with my child for the casting."
Based on the information provided, clubfoot treatment involves corrective casting that gently stretches the foot and keeps it in the proper position. This stretching and casting is typically repeated weekly for several weeks. However, the statement by the mother in option D indicates that she needs to come to the clinic every week with her child for the casting, which is not accurate. The casting is usually done on a regular basis, often weekly, but it is the healthcare provider who performs the casting, not the mother. Therefore, this statement shows a need for further instruction.
