head in dependent position

[h9house]

I came across a practice NCLEX question about Cystic fibrosis and postural drainage. The answers for facilitating the movement of secretions is putting the child's head in a dependent position. It was a select all that apply and the correct answers were:

place child in a side lying position with the right side of the chest elevated on pillows

place the child prone with the thorax and abdomen elevated

place the child in a knee-chest position and place pillows under the chest

so my question is does that mean the head is elevated or dangling since the pillows are placed under the chest, thorax and ABD? My understanding is that dependent means dangling, but it seems odd to let a child's head dangle..

thank you:)
