A nurse is collecting data from a child who has sickle disease and is experiencing a vaso-occlusive crisis. Which of the following findings should the nurse expect?

A. Pain: A vaso-occlusive crisis in sickle cell disease occurs when sickled red blood cells block blood flow in small vessels, leading to severe pain, often in the bones, joints, and abdomen. Pain is the hallmark symptom of a vaso-occlusive crisis. B. Bradycardia: Bradycardia is not typically associated with a vaso-occlusive crisis in sickle cell disease. The child may have an increased heart rate (tachycardia) due to pain, dehydration, or hypoxia. C. Vomiting: Vomiting is not a direct result of a vaso-occlusive crisis but can occur due to complications such as dehydration or infection. D. Constipation: Constipation is not a common symptom of a vaso-occlusive crisis. It may occur as a side effect of medications like opioids, which are often used to manage pain in sickle cell patients.
