Correct Answer: A

Rationale: Surgical resection is the definitive treatment for cystic hygroma.

Correct Answer: C

Rationale: Idiopathic thrombocytopenic purpura (ITP) is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Steroids are often prescribed to help increase platelet production in patients with ITP. Therefore, the nurse should monitor the child for signs of bleeding, such as petechiae, ecchymosis, gum bleeding, and other unusual bleeding manifestations. Monitoring for bleeding is crucial to assess the effectiveness of the steroid treatment and to prevent complications associated with ITP.

Correct Answer: C

Rationale: Encouraging the breastfeeding mother to adhere to a low-phenylalanine diet is an important nursing consideration in the care of the newborn with PKU. Phenylketonuria (PKU) is an inborn error of metabolism in which the body cannot metabolize phenylalanine properly. If a newborn with PKU consumes formula or breast milk that contains high levels of phenylalanine, it can lead to severe intellectual disability and other health complications. By encouraging the breastfeeding mother to follow a low-phenylalanine diet, the newborn's exposure to phenylalanine can be minimized, helping to prevent the negative effects of PKU.
