Correct Answer: A

Rationale: After a prolonged hospitalization, a toddler may exhibit excessively demanding behavior as they readjust to being home. This behavior can stem from the child feeling insecure or anxious about the changes in their environment. The child may seek extra attention and reassurance during this transition period. Choices B, C, and D are incorrect because hostility, shallowness in attachment, and withdrawal without emotional ties are less likely behaviors to be displayed by a toddler readjusting to home after a hospital stay.

Correct Answer: C

Rationale: A moist sterile dressing should be used to protect the exposed bladder tissue from infection and injury. Exstrophy of the bladder requires careful management to prevent complications such as infection. A loose diaper (Choice A) may not provide adequate protection or prevent infection. Dry gauze dressing (Choice B) may not be ideal as it could adhere to the exposed area and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) may not be suitable as it can trap moisture and increase the risk of infection.

Correct Answer: C

Rationale: The most appropriate nursing diagnosis for a child with acute glomerulonephritis is fluid volume excess related to decreased plasma filtration. Acute glomerulonephritis is characterized by inflammation of the glomeruli in the kidneys, leading to decreased plasma filtration and retention of fluid. This results in fluid volume excess rather than fluid deficit (choice B) or fluid accumulation in tissues and third spaces (choice D). The diagnosis of 'risk for injury related to malignant process and treatment' (choice A) is not directly related to the pathophysiology of acute glomerulonephritis.

Correct Answer: B

Rationale: Administering factor VIII in the morning on scheduled days is the correct choice. This timing ensures that the factor VIII levels remain stable throughout the day when the child is active and at risk of bleeding. Choice A is incorrect because factor VIII should be given on a regular schedule rather than only when a bleed is suspected. Choice C is not ideal as the child may be more active during the day, increasing the risk of bleeding. Choice D is also incorrect as the administration should follow a specific schedule to maintain therapeutic levels of factor VIII in the child's system.

Correct Answer: A

Rationale: Monitoring fluid status is crucial for a child with congenital heart disease because these children are at risk of fluid overload which can worsen their condition. Monitoring fluid intake and output helps prevent complications like congestive heart failure. Encouraging activity (Choice B) should be individualized based on the child's condition and tolerance, as excessive activity can strain the heart. Promoting a high-calorie diet (Choice C) is not typically recommended for children with congenital heart disease unless specifically indicated, as excessive weight gain can worsen their cardiac function. Maintaining oxygen therapy (Choice D) may be necessary in some cases, but monitoring fluid status is a more fundamental aspect of care for children with congenital heart disease.
