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: Water is not the best choice for a child who has acute gastroenteritis, as it does not contain the electrolytes and glucose that are lost through vomiting and diarrhea. Water alone can also dilute the blood sodium level and cause hyponatremia.

Choice B reason: Oral rehydration solution is the best choice for a child who has acute gastroenteritis, as it contains the optimal balance of electrolytes and glucose to prevent dehydration and electrolyte imbalance. It also helps to restore the intestinal function and prevent acidosis.

Choice C reason: Diluted apple juice is not the best choice for a child who has acute gastroenteritis, as it contains too much sugar and not enough sodium. This can worsen the diarrhea and cause hyperglycemia and hyperosmolar dehydration.

Choice D reason: Milk is not the best choice for a child who has acute gastroenteritis, as it can aggravate the intestinal inflammation and cause lactose intolerance. Milk can also increase the risk of bacterial infection and septicemia.
