A nurse is assessing a child who is in sickle cell crisis. Which of the following findings should the nurse expect?

A. While fever can occur if the child has an infection, it is not a universal finding of a sickle cell crisis. Fever may indicate a secondary complication, but it is not a hallmark symptom. B. Children in sickle cell crisis may have tachycardia due to pain, hypoxia, or anemia. Bradycardia is not typically associated with sickle cell crisis. C. Pain is the most common and defining manifestation of a sickle cell crisis. It occurs due to vaso-occlusion, which reduces blood flow and oxygen delivery to tissues, leading to ischemia and severe pain. The pain can affect joints, extremities, chest, or abdomen. D. Constipation may occur from medications such as opioids used to manage pain, but it is not a primary symptom of the sickle cell crisis itself.
