What are mummy restraints used for in pediatric care?

Mummy restraints are specifically designed to immobilize very young children during medical procedures, particularly when it is essential to keep them still for safety or to ensure the procedure can be performed accurately. In pediatric care, very young children may struggle to remain calm and still, which can pose a risk during medical assessments or interventions. The technique used in mummy restraints provides a secure but gentle hold, allowing healthcare providers to complete the necessary procedures while also minimizing potential distress for the child.

The other options do not align with the primary purpose of mummy restraints. For instance, promoting physical activity is contrary to the immobilizing aspect of mummy restraints, which is meant to restrain rather than encourage movement. Enhancing blood circulation is not a relevant function of these restraints; they are not used therapeutically for improving circulation. Lastly, while calming aggressive behaviors is important in pediatric care, mummy restraints are not utilized specifically for behavioral management but rather for procedural immobilization. Thus, option B is clearly the correct choice as it identifies the primary function of mummy restraints in a clinical setting.
