Correct Answer: C

Rationale: The correct action to take first when a child with sickle cell anemia presents with severe chest pain, fever, cough, and dyspnea is to notify the practitioner because acute chest syndrome is suspected. This condition is a medical emergency requiring prompt intervention. Administering oxygen or pain medication may be necessary interventions but should not precede notifying the practitioner. Stroke is not typically associated with these symptoms in sickle cell anemia.

Correct Answer: C

Rationale: Abnormal heart sounds could indicate a congenital heart defect, which is common in infants with Down syndrome.

Correct Answer: D

Rationale: A low-phenylalanine diet is necessary for infants with PKU because it helps prevent the accumulation of phenylalanine, which can result in brain damage. Fat-free (Choice A) and protein-enriched (Choice B) diets are not specifically indicated for PKU. While phenylalanine-free (Choice C) may seem logical, complete elimination of phenylalanine is not practical or safe as it is an essential amino acid. Therefore, the correct choice is a low-phenylalanine diet, which restricts phenylalanine intake to a safe level.

Correct Answer: D

Rationale: It is recommended to perform palate closure surgery before the child starts using faulty speech patterns to prevent the development of speech issues that may be harder to correct later. Delaying surgery until after the age of 2 can lead to the child forming incorrect speech habits, which can be challenging to correct. Choices A, B, and C are incorrect because they do not address the specific concern related to speech development in children with cleft palates.

Correct Answer: B

Rationale: During a check-up for a child with eczema, assessing compliance with treatment regimens is a key nursing intervention. This helps ensure that the child is following the prescribed treatment plan effectively, which is crucial in managing eczema and preventing flare-ups. Changing a bandage on a cut is not directly related to managing eczema. Discussing systemic corticosteroid therapy may be part of the visit, but assessing compliance is more immediate and essential. Assessing the child's fluid volume is important for overall health assessment but not specifically related to managing eczema.
