The National Pediculosis Association (2004) recommends that the nurse examining children's hair for lice and nits should ________.
1) Wear gloves at all times, and change the gloves for each new examination.
2) Use wooden tongue depressors, discarded after each examination, to examine the child's hair.
3) Use ungloved hands, and wash the hands carefully with soap after the examination.
4) Use a comb to part the hair, and do not touch the hair itself with anything other than the comb.
