Correct Answer: D

Rationale: The correct answer is D: Monitoring for signs of infection. When a child with leukemia presents with a fever, the priority nursing intervention is to monitor for signs of infection due to the immunocompromised state of the child. Administering antibiotics (choice A) may be necessary based on the assessment of signs of infection, but monitoring comes first. Administering antipyretics (choice B) helps to reduce fever but does not address the underlying cause. Providing nutritional support (choice C) is essential but not the priority when the child is at risk of infection.

Correct Answer: A

Rationale: A webbed neck is a classic physical characteristic seen in individuals with Turner syndrome, a genetic condition that results from a missing or partially missing X chromosome in females. This distinctive feature occurs due to excess skin on the neck and is a key clinical clue for healthcare providers. Microcephaly (choice B) refers to a small head size and is not typically associated with Turner syndrome. Gynecomastia (choice C) is the enlargement of breast tissue in males and is not a common finding in Turner syndrome. Cognitive delay (choice D) involves intellectual or developmental delays and is not a specific feature of Turner syndrome.

Correct Answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

Correct Answer: C

Rationale: Circumoral cyanosis should alert the nurse to perform a further assessment because it may indicate inadequate oxygenation or circulation, potentially related to cardiac or respiratory issues. Flat occiput (choice A) is a common finding in infants and is not typically concerning. Small, low-set ears (choice B) are common in Down syndrome and not specifically indicative of an acute issue requiring immediate further assessment. Protruding furrowed tongue (choice D) is also commonly seen in infants with Down syndrome and typically does not warrant immediate further assessment unless associated with other concerning signs or symptoms.

Correct Answer: D

Rationale: The priority nursing intervention for a child with leukemia admitted to the hospital with a fever is to monitor for signs of infection. Children with leukemia are immunocompromised, making them more susceptible to infections. Monitoring for signs of infection helps in early detection and timely intervention, which is crucial in preventing complications. Administering antibiotics (choice A) may be necessary if an infection is suspected or confirmed, but the priority is to assess for signs of infection first. Administering antipyretics (choice B) may help reduce fever, but it does not address the underlying cause, which could be an infection. Providing nutritional support (choice C) is important for overall health but is not the priority when a child with leukemia presents with a fever, as infection needs to be ruled out or managed first.
