Which instruction should the nurse give to a patient with pediculosis pubis?
A) "Use an over-the-counter lotion with permethrin."
B) "Apply a second treatment of permethrin 7 days after the first treatment."
C) "Wash all linens and towels in cold water."
D) "Place items that cannot be washed in a garbage bag for one week."
A) "Use an over-the-counter lotion with permethrin."
Explanation: A) Pediculosis pubis can be treated with over-the-counter permethrin (usually 1%) lotion.
B) Permethrin is highly effective against live lice; however, it will not penetrate unhatched nits. A second treatment with permethrin is recommended roughly 9 days after the first treatment to kill any newly hatched nits to prevent another life cycle. Delaying or omitting this second treatment can lead to the new lice laying more nits, which will contribute to reinfestation.
C) Towels, clothing, and even bedding from the patient's environment used within 2-3 days before treatment should be machine-washed in water of at least 130 degrees Fahrenheit and dried on the hot setting in a dryer to kill the remaining lice and nits.
D) Any items that cannot be washed need to be disposed of or placed in a garbage bag for a period of no less than 2 weeks. This will kill the remaining lice and nits within the soiled cloth.
