A nurse is teaching a class about physiological changes to hearing in older adult clients. Which of the following should the nurse include?

Choice A reason: This is correct because the lesion on the child's head is most likely a hemangioma, which is a benign tumor of blood vessels that appears as a red or purple mark on the skin. Hemangiomas are common in newborns and usually grow during the first year of life, then shrink and fade over several years. The nurse should reassure the client that hemangiomas are harmless and do not require treatment unless they interfere with vision, breathing, or feeding.
Choice B reason: This is incorrect because the lesion on the child's head will not spread, but rather grow and shrink within a limited area. The nurse should not alarm the client by suggesting that the lesion will spread to other parts of the body or become malignant. The nurse should explain that hemangiomas are not contagious or infectious and do not affect the child's overall health or development.
Choice C reason: This is incorrect because the lesion on the child's head is not caused by scarring from the birth process, but rather by abnormal growth of blood vessels in the skin. The nurse should not confuse or misinform the client about the cause of the lesion. The nurse should explain that hemangiomas are not related to trauma, infection, or genetics, but rather to unknown factors that influence blood vessel formation during fetal development.
Choice D reason: This is incorrect because the lesion on the child's head is not a precancerous lesion and does not need a referral to a dermatologist. The nurse should not scare or mislead the client by suggesting that the lesion is a sign of cancer or requires further evaluation or treatment. The nurse should explain that hemangiomas are benign and usually resolve on their own without any complications or sequelae.

Choice A Reason: This is the correct choice. Using the rule of nines, each arm accounts for 9 percent of TBSA, each leg accounts for 18 percent of TBSA, and front and back are equally divided. Therefore, burns on both sides of both arms and legs equal to (9 + 9) x 2 + (18 + 18) x 2 = 36 percent of TBSA.

Choice B Reason: This choice is incorrect. Using the rule of nines, burns on both sides of both arms and legs equal to 36 percent of TBSA, not 54 percent. To get 54 percent of TBSA, one would have to add burns on both sides of head and neck (9 percent), chest (9 percent), and abdomen (9 percent).

Choice C Reason: This choice is incorrect. Using the rule of nines, burns on both sides of both arms and legs equal to 36 percent of TBSA, not 27 percent. To get 27 percent of TBSA, one would have to subtract burns on both sides of one leg (18 percent).

Choice D Reason: This choice is incorrect. Using the rule of nines, burns on both sides of both arms and legs equal to 36 percent of TBSA, not 18 percent. To get 18 percent of TBSA, one would have to divide burns on both sides of both arms and legs by two.

Choice E Reason: This choice is incorrect. Using the rule of nines, burns on both sides of both arms and legs equal to 36 percent of TBSA, not 9 percent. To get 9 percent of TBSA, one would have to divide burns on both sides of both arms and legs by four.
