Parents of a school-age child with hemophilia ask the nurse, "Which sports are recommended for children with hemophilia?" Which sport should the nurse recommend?

Choice A rationale:
Correction of acidosis is not the primary intervention for vaso-occlusive sickle cell crisis. The crisis primarily involves pain due to the obstruction of blood flow by sickled cells. Correcting acidosis is not a direct treatment for this condition.
Choice B rationale:
Adequate hydration is essential in managing vaso-occlusive sickle cell crisis. Proper hydration helps prevent dehydration, which can worsen the crisis and lead to complications. Hydration helps maintain blood flow and prevent further sickling of red blood cells.
Choice C rationale:
Pain management is a crucial intervention for a child with vaso-occlusive sickle cell crisis. Pain results from tissue ischemia caused by sickled red blood cells. Effective pain management, often with analgesics, helps improve the child's comfort and quality of life during the crisis.
Choice D rationale:
Administration of heparin is not indicated for vaso-occlusive sickle cell crisis. Heparin is an anticoagulant that prevents blood clot formation. In sickle cell crisis, the primary issue is the obstruction of blood flow by sickled cells, not the formation of clots. Administering heparin may not address the underlying problem and can lead to potential complications.
Choice E rationale:
Replacement of factor VIII is not relevant to vaso-occlusive sickle cell crisis. Factor VIII is a protein involved in blood clotting and is primarily used in the treatment of hemophilia, a different condition unrelated to sickle cell crisis.

The correct answer is Choice A.

Choice A rationale: Increasing the caloric density of an infant's formula provides more calories in a smaller volume, reducing the energy expenditure required for feeding. This approach ensures the infant receives adequate nutrition while managing heart failure symptoms effectively.

Choice B rationale: Feeding an infant every 2 hours can lead to feeding intolerance and fatigue. Infants with heart failure often have limited energy reserves and need longer intervals between feedings to conserve energy and improve feeding effectiveness.

Choice C rationale: Increasing the amount of formula per feeding can overwhelm an infant with heart failure, leading to fatigue and decreased feeding efficiency. Smaller, frequent feedings with higher caloric density are more effective in providing necessary nutrients.

Choice D rationale: Placing a nasal oxygen cannula on an infant during feeding is not a standard recommendation for managing heart failure. While oxygen therapy may be necessary for some infants, it is not specifically tied to feeding practices and should be used based on individual clinical assessments.
