Correct Answer: D

Rationale: Cleft palate is considered a major congenital anomaly because it involves a gap or split in the roof of the mouth, which can significantly impact feeding, speech development, dental health, and overall well-being. Overlapping digits (Choice A) and polydactyly (Choice B) are examples of limb abnormalities rather than major congenital anomalies affecting vital functions. Umbilical hernia (Choice C) is a common condition where abdominal organs protrude through the belly button and is typically not considered a major congenital anomaly in the same way as cleft palate.

Correct Answer: B

Rationale: Ensuring adequate hydration is crucial during a vaso-occlusive crisis in sickle cell anemia as it helps to reduce the viscosity of the blood and prevent further sickling of the cells. While administering oxygen may be necessary in some cases, ensuring hydration takes precedence as it directly impacts the underlying pathophysiology of the crisis. Monitoring vital signs is important for ongoing assessment but does not directly address the crisis as hydration does. Administering pain medication is important for pain relief but does not address the primary issue of vaso-occlusion and is not the most crucial intervention in this scenario.

Correct Answer: A

Rationale: A cough is a common clinical manifestation of pneumonia. Pneumonia often presents with symptoms such as cough, fever, chest pain, and difficulty breathing. The inflammation and infection in the lungs lead to the characteristic cough observed in patients with pneumonia. Diarrhea, rash, and vomiting are not typically associated with pneumonia and are less likely to be observed in a child with this condition.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial in managing asthma as certain foods can trigger or worsen symptoms. Monitoring dietary habits helps identify any potential triggers and ensures proper nutrition, which can impact asthma control. Assessing sleep patterns, academic performance, or behavior at home may provide valuable information in a general health assessment, but when specifically managing asthma, dietary intake assessment is the most relevant.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial in managing asthma as certain foods can trigger symptoms or exacerbate the condition. By evaluating the child's diet, the nurse can identify potential triggers, ensure the child receives proper nutrition, and help manage symptoms effectively. Assessing sleep patterns, academic performance, or behavior at home, while important in a holistic assessment, are not as directly related to managing asthma symptoms as dietary intake.
