What statement indicates a 12-year-old child needs further explanation regarding a bone marrow aspiration?

The statement requiring further explanation is the one about putting a tight bandage on where the needle goes in. This indicates that the child may not fully understand the procedure or its implications. While the child is aware that there is a need for a bandage after the procedure, the phrase "tight bandage" suggests a misunderstanding of the necessity or nature of post-procedure care.

In a bone marrow aspiration, the focus should be on proper care to avoid complications, which may not require applying a tight bandage. The importance lies in understanding the procedure and ensuring comfort during recovery without causing concern about tightness or discomfort.

In contrast, the other statements reflect more accurate expectations following the procedure: resting, experiencing soreness, and understanding the basic action of the needle insertion into the hip bone. These indicate that the child has a basic grasp of what to expect regarding the procedures and aftermath, suggesting that their understanding is adequate in those areas.
