The patient received a diagnosis of pediculosis capitis (head lice) ,was treated upon admission and re-treated 24 hours later,and yet the patient still has the infestation.What should be the nurse's next action?

A) Re-treat the patient with a medicated shampoo for eliminating lice.
B) Use a product containing lindane to get rid of the lice.
C) Manually remove the lice using a fine-toothed comb.
D) Have the patient bathe or shower thoroughly.

Manual removal is the best option when treatment has failed.Re-treating with a medicated shampoo may lead to adverse reactions and should not be done without consulting the care provider.Products containing lindane should not be used because the ingredient is toxic and is known to cause adverse reactions.Although bathing or showering is a good idea,this is usually considered a treatment for pediculosis corporis (body lice),not pediculosis capitis (head lice).
