A nurse is caring for a toddler who is scheduled to have a lumbar puncture. Which of the following actions should the nurse take?

A. Restrain the toddler for 1 hr after the procedure: This is not necessary; the child should be monitored but not restrained. B. Place the toddler in a side-lying, knee-chest position: This position helps to open the spaces between vertebrae, facilitating the lumbar puncture. C. Ask another nurse to assist with holding the toddler in a prone position: The prone position is not appropriate for a lumbar puncture as it does not provide proper spinal alignment. D. Swaddle the toddler in a warm blanket: While comforting, it is not relevant to the procedure itself.
