Correct Answer: A

Rationale: The priority nursing intervention when caring for a child with sickle cell anemia is administering pain medication. Pain management is crucial in sickle cell anemia due to vaso-occlusive crises that can cause severe pain. While ensuring adequate hydration, providing nutritional support, and monitoring vital signs are important aspects of care for a child with sickle cell anemia, addressing the pain with appropriate medication takes precedence to alleviate the child's suffering and improve their quality of life.

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: The most important factor in preparing a toddler for additional surgery is their previous experience of hospitalization. This familiarity can help reduce anxiety and fear associated with the hospital environment and medical procedures. Choice A, satisfying the child's wishes, may not always be feasible or in the child's best interest during medical procedures. Choice C, preventing the child from being with strangers, may not address the core issue of preparing the child for surgery. Choice D, ensuring the child still receives parental affection, is important but may not directly address the preparation needed for surgery.

Correct Answer: B

Rationale: The priority nursing care after a cardiac catheterization in a 3-year-old is to monitor the site for bleeding. This is essential to promptly detect and manage any potential complications, such as hematoma or hemorrhage. Encouraging early ambulation, as mentioned in choice A, may not be safe immediately post-procedure and should be guided by the healthcare provider's instructions. Restricting fluids until blood pressure is stabilized, as in choice C, is not typically necessary after a cardiac catheterization. Comparing blood pressure in both lower extremities, as in choice D, is not the priority immediate nursing care following this procedure.

Correct Answer: D

Rationale: At 10 months of age, pulling to a stand is a developmental milestone that most infants can achieve. Crawling typically occurs around 6-9 months, sitting without support around 6-8 months, and standing with assistance around 7-11 months. Therefore, choices A, B, and C are not the expected developmental milestones for a 10-month-old infant.
