The nurse is performing a routine assessment of a 3-year-old at a community health center. Which behavior by the child should alert the nurse to request a follow-up for a possible autism spectrum disorder (ASD)?

Choice A reason: Taking the child to a hair salon for a shampoo and a shorter haircut is not a good instruction that the nurse should provide. This is because a hair salon may not accept a child with head lice, as they can spread to other customers and staff. A shorter haircut may also not help to get rid of the lice or their eggs, which can attach to any length of hair.

Choice B reason: Rewashing the child's hair following a 24-hour isolation period is not a good instruction that the nurse should provide. This is because a 24-hour isolation period is not necessary or effective for treating head lice. Head lice do not survive long without a human host, and they do not spread through the air or by jumping. Rewashing the child's hair may also wash off the permethrin shampoo, which needs to stay on the hair for 10 minutes to kill the lice and their eggs.

Choice C reason: Washing the child's bed linens and clothing in hot soapy water is a good instruction that the nurse should provide. This is because head lice and their eggs can be transferred to the child's bedding and clothing through direct contact. Washing these items in hot water (at least 130°F or 54°C) and drying them on high heat can kill any remaining lice or eggs. Alternatively, the items can be sealed in plastic bags for two weeks to suffocate the lice.

Choice D reason: Disposing of the child's brushes, combs, and other hair accessories is not a good instruction that the nurse should provide. This is because it is not necessary to throw away these items, as they can be treated and reused. The nurse should advise the parents to soak the items in hot water (at least 130

Choice A reason: Instructing the mother to feed the infant nothing for 30 minutes after giving the iron drops is not a correct intervention. It may cause the infant to become hungry, fussy, or dehydrated. It may also interfere with the absorption of iron, as food can enhance the bioavailability of iron in the body.

Choice B reason: Suggesting placing the iron drops in the orange juice and then feeding the infant is not a correct intervention. It may alter the taste and color of the orange juice, making it less palatable for the infant. It may also reduce the potency of the iron drops, as iron can react with the citric acid and vitamin C in the orange juice and form insoluble complexes.

Choice C reason: Telling the mother to follow the iron drops with infant formula instead of orange juice is not a correct intervention. It may decrease the absorption of iron, as calcium and casein in the infant formula can bind with iron and form insoluble complexes. It may also increase the risk of gastrointestinal side effects, such as constipation, nausea, or vomiting.

Choice D reason: Giving the mother positive feedback about the way she administered the medication is a correct intervention. It reinforces the mother's behavior and encourages her to continue giving the iron drops as prescribed. It also acknowledges the mother's efforts and shows respect and appreciation. Following the iron drops with orange juice is a good practice, as vitamin C in the orange juice can enhance the absorption of iron in the body.
