A nurse collects the health history of a 65-year-old client. Which of the following risk factors in the client's history puts the client at the highest risk for embolic stroke?

Choice A Reason: Obtaining the client's blood glucose every 12 hr is not enough, as the nurse should monitor it more frequently, at least every 4 to 6 hr, to prevent hyperglycemia or hypoglycemia. TPN is a high-glucose solution that can affect the blood sugar levels.

Choice B Reason: Changing the IV site dressing every 4 days is not enough, as the nurse should change it daily or as needed to prevent infection. TPN is a high-risk solution that can introduce microorganisms into the bloodstream.

Choice C Reason: This is the correct choice. Changing the IV tubing every 24 hr is recommended to prevent infection and maintain sterility. TPN is a complex solution that can support bacterial growth and contamination.

Choice D Reason: Weighing the client every other day is not enough, as the nurse should weigh the client daily to evaluate fluid balance and nutritional status. TPN can cause fluid retention or depletion, as well as weight gain or loss.

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.
