Pediatric HESI 2024

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: C

Rationale: The correct answer is to maintain standard and contact precautions. RSV is highly contagious, primarily spreading through respiratory secretions. Therefore, it is crucial to implement infection control measures to prevent the spread of the virus within the healthcare setting. Option A is incorrect as warmth and dryness are not the primary concern in RSV management. While family support is important, allowing visits may increase the risk of spreading the infection, making option B less appropriate. Option D is incorrect because RSV is a viral infection, and antibiotics are not effective against viruses.

Correct Answer: A

Rationale: Petechiae, infection, and fatigue are common signs and symptoms of leukemia related to bone marrow involvement. Petechiae are small red or purple spots on the skin caused by bleeding under the skin due to low platelet counts. Infection susceptibility increases due to decreased white blood cells from compromised bone marrow function. Fatigue is a common symptom of anemia resulting from decreased red blood cell production. Choices B, C, and D are incorrect as they do not align with the typical signs and symptoms of leukemia associated with bone marrow dysfunction.

Correct Answer: D

Rationale: The classification is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation between acyanotic and cyanotic defects. Choice A is incorrect because the system is not solely based on explaining hemodynamics. Choice B is incorrect because the classification is not based on the ease of identifying children with cyanotic defects. Choice C is incorrect because cyanosis can indeed be present in children with congenital heart defects, especially acyanotic defects that may lead to cyanosis under certain circumstances.

Correct Answer: A

Rationale: In sickle cell anemia, pain management is a priority due to vaso-occlusive crises that cause severe pain. Administering pain medication helps alleviate discomfort and improve the child's quality of life. Ensuring adequate hydration, although important, is secondary to addressing the immediate pain issue. Providing nutritional support is beneficial for overall health but does not address the acute pain experienced. Monitoring vital signs is essential but not the immediate priority when managing pain in sickle cell anemia.
