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?
Take the child to a hair salon for a shampoo and a shorter haircut.
Rewash the child's hair following a 24-hour isolation period.
Wash the child's bed linens and clothing in hot soapy water.
Dispose of the child's brushes, combs, and other hair accessories.
The Correct Answer is C
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

Correct Answer is D
Explanation
Choice A reason: Playing "peek-a-boo" is a normal behavior for a 6-month-old infant. It shows that the infant has developed object permanence, which is the understanding that objects and people still exist even when they are out of sight. This is a sign of cognitive development and social interaction.
Choice B reason: Turning head to locate sound is a normal behavior for a 6-month-old infant. It shows that the infant has developed auditory localization, which is the ability to identify the direction and distance of a sound source. This is a sign of sensory development and curiosity.
Choice C reason: Having doubled birth weight is a normal milestone for a 6-month-old infant. It shows that the infant has adequate growth and nutrition. The average birth weight for a full-term infant is about 3.4 kg (7.5 lb), and the average weight for a 6-month-old infant is about 6.8 kg (15 lb).
Choice D reason: Demonstrating startle reflex is an abnormal behavior for a 6-month-old infant. The startle reflex, also known as the Moro reflex, is an involuntary response to a sudden loud noise or movement. The infant will extend the arms and legs, arch the back, and then curl the arms and legs inward. This reflex is present at birth and usually disappears by 4 months of age. If the reflex persists beyond 6 months of age, it may indicate a neurological problem or developmental delay. The nurse should request further evaluation by the health care provider.
Correct Answer is B
Explanation
Choice A reason: Luteinizing hormone (LH) levels are not relevant for the diagnosis of congenital hypothyroidism. LH is a hormone that regulates the reproductive system and is not affected by thyroid function.
Choice B reason: Thyroxine (T4) is the main hormone produced by the thyroid gland and is essential for growth and development. Low levels of T4 indicate hypothyroidism and require treatment with thyroid hormone replacement. High levels of T4 indicate hyperthyroidism and require treatment with anti-thyroid drugs.
Choice C reason: Growth hormone (GH) levels are not relevant for the diagnosis of congenital hypothyroidism. GH is a hormone that stimulates growth and metabolism and is not affected by thyroid function.
Choice D reason: Follicle stimulating hormone (FSH) levels are not relevant for the diagnosis of congenital hypothyroidism. FSH is a hormone that regulates the reproductive system and is not affected by thyroid function.
