A nurse is educating the parent of a toddler who has sickle cell anemia. Which of the following statements by the parent indicates that the teaching was effective?

This scenario involves teaching parents about long-term management and crisis prevention for a child with sickle cell anemia. Knowledge of the pathophysiology of vaso-occlusive crises triggered by physical stress, dehydration, and trauma is required to identify safe activities. Choice A rationale . Prophylactic penicillin is often prescribed to prevent bacterial infections, specifically Streptococcus pneumoniae, because the spleen is often non-functional. It does not prevent viral infections, and the parent's statement misidentifies the primary goal of the daily medication. Choice B rationale . Children with sickle cell anemia are immunocompromised and require all standard immunizations plus extras like pneumococcal and meningococcal vaccines. Avoiding immunizations would leave the child vulnerable to life-threatening infections that could trigger a vaso-occlusive sickle crisis. Choice C rationale . Blood transfusions are used to treat severe anemia or to prevent stroke in high-risk patients, but they are not a universal monthly requirement for all children. Frequent transfusions also carry risks like iron overload and alloimmunization. Choice D rationale . Avoiding contact sports is vital to prevent physical trauma and excessive physical exertion, which can trigger sickle cell crises. Protecting the enlarged spleen from rupture is also a priority in managing the health and safety of toddlers.
