A nurse is planning care for a preschooler who has leukemia. After reviewing the child's information, which of the following potential issues should the nurse identify that the child is at risk for developing? (Select all that apply.)

Choice A reason: A child who has rheumatic fever is a suitable roommate for a child who has leukemia, as rheumatic fever is not a contagious condition, and it does not pose any risk of infection or cross-reaction to the child who has leukemia. Rheumatic fever is an inflammatory disease that can affect the heart, joints, skin, and brain, and it is caused by a delayed immune response to a streptococcal infection.

Choice B reason: A child recovering from a ruptured appendix is not a suitable roommate for a child who has leukemia, as a ruptured appendix can cause peritonitis, which is a serious infection of the abdominal cavity, and it can be a source of bacteria or fungi that can spread to the child who has leukemia. A child who has leukemia has a compromised immune system and is susceptible to infections.

Choice C reason: A child who has nephrotic syndrome is not a suitable roommate for a child who has leukemia, as nephrotic syndrome can cause edema, proteinuria, hypoalbuminemia, and hyperlipidemia, and it can be associated with infections, allergies, or autoimmune disorders that can affect the child who has leukemia. A child who has leukemia has a reduced number of blood cells and is prone to bleeding, anemia, and infections.

Choice D reason: A child who has cystic fibrosis is not a suitable roommate for a child who has leukemia, as cystic fibrosis is a genetic disorder that affects the lungs, pancreas, liver, and intestines, and it can cause chronic respiratory infections, malabsorption, and diabetes, which can compromise the health of the child who has leukemia. A child who has leukemia has a weakened immune system and is vulnerable to infections.

Choice A reason: This statement is incorrect because administering iron at bedtime can cause gastrointestinal upset and interfere with the child's sleep. Iron should be given between meals or one hour before meals for better absorption.

Choice B reason: This statement is correct because giving iron with orange juice or other foods rich in vitamin C can enhance iron absorption. Vitamin C helps convert iron into a form that is more easily absorbed by the body.

Choice C reason: This statement is incorrect because administering iron at mealtimes can reduce iron absorption. Iron can bind with certain substances in food, such as calcium, phytates, and tannins, and make it less available for the body.

Choice D reason: This statement is incorrect because giving iron with milk can decrease iron absorption. Milk contains calcium, which can interfere with iron absorption. Milk can also cause nausea and vomiting when taken with iron.
