  electrodes to the scalp.

  Food or fluids do not need to be restricted, with the exception of caffeinated fluids.

  There is no restriction on metal objects.

  Correct Answer: D

  Gentle bubbling is a normal finding for the client who has a pleural drainage system to suction, so it simply

  needs to be documented. If the bubbling becomes vigorous, it could indicate a leak, which the nurse needs

  to investigate.

  The remaining choices are not necessary.

  A chest drainage system should be placed below the level of the client's chest so that the drainage flows

  out of the chest into the system.

  The remaining choices are too high and do not allow fluid to drain out of the chest.
