When caring for a child with sickle cell disease, the practical nurse (PN) expects that the child will most likely describe which symptom when experiencing a sickle cell crisis?

A. Infection: Infection is a common complication of sickle cell disease due to functional asplenia, but it is not the hallmark symptom experienced during an acute sickle cell crisis. B. Joint pain: Pain, especially in joints, bones, and extremities, is the most frequent and prominent symptom during a sickle cell crisis. It results from vaso-occlusion causing ischemia and tissue injury, making pain management a primary focus of care. C. Fatigue: Fatigue is common in chronic anemia associated with sickle cell disease but is usually a baseline symptom rather than an acute manifestation of a crisis. D. Decreased hemoglobin: Hemoglobin levels may decrease during a crisis due to hemolysis, but the child may not directly perceive this; the most noticeable symptom reported is pain.
