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?

The correct answer is: B. I will add Polycose to each of my baby's bottles.

Choice A reason:

Allowing the baby to take as much time as needed to finish the bottle is not ideal for infants with heart failure. These infants often tire easily and may not consume enough calories if feeding sessions are prolonged. Shorter, more frequent feedings are generally recommended to ensure adequate intake without exhausting the infant.

Choice B reason:

Adding Polycose to each bottle is an effective way to increase the caloric density of the infant's feedings. Infants with heart failure have higher caloric needs due to their increased metabolic demands and may struggle to consume enough calories through regular formula or breast milk alone. Polycose, a carbohydrate supplement, helps meet these increased nutritional needs.

Choice C reason:

Feeding the baby on a schedule every 4 hours may not be sufficient for an infant with heart failure. These infants often require more frequent feedings to meet their caloric needs and to prevent fatigue during feeding. Feeding every 1-3 hours is typically recommended to ensure they receive adequate nutrition.

Choice D reason:

Limiting the baby's crying to 15 minutes prior to each feeding does not directly address the nutritional needs of an infant with heart failure. While managing crying is important to reduce energy expenditure, the focus should be on providing adequate nutrition through frequent, high-calorie feedings.

Choice A reason: Pyloric stenosis is not a manifestation of inadequate motility of part of the intestine, but rather a hypertrophy of the pyloric muscle, which causes gastric outlet obstruction and delayed gastric emptying. Pyloric stenosis typically presents with projectile vomiting, dehydration, weight loss, and a palpable olive-shaped mass in the abdomen.

Choice B reason: Hirschsprung's disease is a manifestation of inadequate motility of part of the intestine, as it is caused by the absence of ganglion cells in the distal colon, which results in a lack of peristalsis and a functional obstruction. Hirschsprung's disease typically presents with constipation, abdominal distension, failure to thrive, and enterocolitis.

Choice C reason: Encopresis is not a manifestation of inadequate motility of part of the intestine, but rather a condition in which a child over 4 years of age involuntarily passes stool, usually due to chronic constipation and fecal impaction. Encopresis typically presents with soiling of the underwear, abdominal pain, low self-esteem, and behavioral problems.

Choice D reason: Enterocolitis is not a manifestation of inadequate motility of part of the intestine, but rather an inflammation of the mucosa of the small and large intestines, which can be caused by various infections, allergies, or ischemia. Enterocolitis typically presents with diarrhea, fever, abdominal pain, and dehydration.
