Rationale: Allowing the child to eat any food desired and tolerated is the most appropriate intervention for a child with altered nutrition due to anorexia, nausea, and vomiting. It is crucial to prioritize maintaining adequate nutritional intake, and by allowing the child to choose foods they desire and can tolerate, the chances of improving their nutritional status increase. This approach helps in ensuring that the child receives necessary nutrients during chemotherapy, even if their appetite is affected by the treatment.

Rationale: In a child with a history of iron-deficiency anemia presenting with symptoms of fatigue, pallor, and shortness of breath, the priority action for the nurse is to administer iron supplements as prescribed. Iron supplementation is essential to treat iron-deficiency anemia and improve the child's symptoms promptly.

Correct Answer: A

Rationale: The correct instruction for the nurse to provide to the parents is to wash the child's bed linens and clothing in hot soapy water. This is essential to eliminate head lice as they can survive on bedding and clothing. It is also important to wash any other items that the child may have used or come into contact with, such as brushes and combs, to prevent reinfestation. Rewashing the child's hair following an isolation period is not necessary, and taking the child to a hair salon for a shampoo and shorter haircut is not a recommended treatment for head lice.

Correct Answer: C

Rationale: The correct answer is C. Chest physiotherapy should not be performed right after meals to avoid inducing vomiting. It should be done before meals or at least 1 hour after for effective mucus clearance and to prevent any potential complications like vomiting.

Correct Answer: D

Rationale: Flaring of the nares is a classic sign of acute respiratory distress in infants. It indicates increased work of breathing and is a visible cue that the child is struggling to breathe. This finding should alert healthcare providers to the severity of the respiratory distress and the need for prompt intervention to support the child's breathing.
