A nurse is caring for an 18-month-old toddler in the emergency department who has Kawasaki disease. The nurse reviews the toddler's medical record and assessment findings. Which of the following provider prescriptions should the nurse anticipate?

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: Ridged abdomen is not an expected finding for an infant who has pyloric stenosis, as it indicates abdominal rigidity or guarding, which can be a sign of peritonitis or bowel obstruction. Pyloric stenosis is a narrowing of the pyloric sphincter, which causes gastric outlet obstruction and delayed gastric emptying.

Choice B reason: Red currant jelly stools are not an expected finding for an infant who has pyloric stenosis, as they indicate blood and mucus in the stools, which can be a sign of intussusception or necrotizing enterocolitis. Pyloric stenosis does not affect the lower gastrointestinal tract, and the infant may have constipation or dehydration due to vomiting.

Choice C reason: Projectile vomiting is an expected finding for an infant who has pyloric stenosis, as it occurs after feeding due to the increased pressure in the stomach and the inability to pass food into the duodenum. Projectile vomiting can cause weight loss, dehydration, electrolyte imbalance, and metabolic alkalosis.

Choice D reason: Distended neck veins are not an expected finding for an infant who has pyloric stenosis, as they indicate increased central venous pressure, which can be a sign of heart failure or superior vena cava syndrome. Pyloric stenosis does not affect the cardiovascular system, and the infant may have sunken fontanels or poor skin turgor due to dehydration.
