A nurse is admitting a 6-month-old infant who has dehydration. Which of the following amounts of urinary output should indicate to the nurse that the treatment has corrected the fluid imbalance?

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: Tracheoesophageal fistula is a congenital anomaly that results from an abnormal connection between the trachea and the esophagus. It causes respiratory distress, choking, coughing, and cyanosis during feeding, and increased risk of aspiration pneumonia.

Choice B reason: Inguinal hernia is a protrusion of abdominal organs through the inguinal canal into the scrotum or labia. It causes a bulge in the groin area that may increase in size with crying or straining. It may also cause pain, vomiting, and impaired blood flow to the herniated tissue.

Choice C reason: Intussusception is a telescoping of one segment of the bowel into another, causing obstruction and impaired blood supply. It causes a palpable mass in the upper right quadrant, stools mixed with blood and mucus (resembling currant jelly), abdominal pain, vomiting, and shock.

Choice D reason: Hypertrophic pyloric stenosis is a narrowing of the pyloric sphincter due to hypertrophy of the surrounding muscle. It causes projectile vomiting, dehydration, weight loss, and a palpable olive-shaped mass in the upper right quadrant.
