A preschool-age boy in a daycare facility scratches his head frequently, and the nurse confirms the presence of head lice. The nurse washes the child's hair with permethrin shampoo and calls his parents. Which instruction should the nurse provide to the parents about treatment for head lice?

Choice A reason: Positioning the infant on the stomach occasionally when awake and active is the best response that the nurse can give to the mother. This is because it can help prevent and correct the flat head syndrome, also known as plagiocephaly, by taking pressure off the back of the head and allowing the skull to reshape naturally. It can also promote the infant's motor development and strengthen the neck and shoulder muscles. However, the nurse should also remind the mother to always place the infant on the back when sleeping, as this is the safest position to reduce the risk of sudden infant death syndrome (SIDS) .

Choice B reason: Turning the infant on the left side braced against the crib when sleeping is not a good response that the nurse can give to the mother. This is because it can increase the risk of SIDS, as the infant may roll over to the stomach or suffocate from the bedding or the crib. It can also worsen the flat head syndrome by creating another flat spot on the left side of the head.

Choice C reason: Placing a small pillow under the infant's head while lying on the back is not a good response that the nurse can give to the mother. This is because it can increase the risk of SIDS, as the pillow may cover the infant's face or cause the infant to overheat. It can also interfere with the natural reshaping of the skull and cause neck strain.

Choice D reason: Propping the infant in a sitting position with a cushion when not sleeping is not a good response that the nurse can give to the mother. This is because it can put too much pressure on the spine and the pelvis, which are still developing in the infant. It can also limit the infant's movement and exploration, which are important for learning and development.

Choice A reason: Starting the daughter on birth control pills is not necessary and may interfere with the LHRH treatment. LHRH injections suppress the production of sex hormones and prevent ovulation and menstruation. Birth control pills contain synthetic hormones that may have unwanted side effects and may not be effective in preventing pregnancy in girls with precocious puberty.

Choice B reason: Encouraging the daughter to dress in clothing that suits her sexual maturity level is not advisable and may cause psychological distress. Girls with precocious puberty may feel self-conscious and embarrassed about their early physical development and may face teasing or bullying from their peers. Dressing in clothing that accentuates their sexual maturity may make them feel more uncomfortable and isolated. They should be allowed to dress in clothing that matches their age and emotional development.

Choice C reason: The daughter will not be on this hormone treatment the rest of her life. LHRH injections are usually given until the age of normal puberty, around 11 or 12 years old. Then, the treatment is stopped and the natural puberty process resumes. The injections are meant to delay puberty, not stop it permanently.

Choice D reason: Sexual maturity differences between the daughter and her peers will disappear within a few years is the correct statement that shows understanding of the treatment. LHRH injections slow down the growth and development of the sex organs and secondary sexual characteristics, such as breasts and pubic hair. This allows the girl to grow at a normal rate and reach her full adult height potential. It also reduces the social and emotional problems that may arise from being sexually mature too early. Once the treatment is stopped, the girl will go through puberty at the same time as her peers and the differences will no longer be noticeable.
