A nurse is caring for a child who is postoperative following surgical correction of Tetralogy of Fallot. Which of the following findings should the nurse identify as an indication of heart failure?

Choice A reason: Teaching the child about cast care is important, but it is not the first action to take. Education on cast maintenance and activity restrictions will follow after addressing immediate needs.

Choice B reason: Administering pain medication should be the first action taken by the nurse. After a cast application for a fracture, the child is likely experiencing pain, and managing this pain is a priority to ensure comfort and facilitate healing.

Choice C reason: Elevating the child's leg is a subsequent action that can help reduce swelling and discomfort, but it is not the first action to take. Pain management is the priority before positioning.

Choice D reason: Petaling the edges of the cast, which involves placing soft material around the rough edges to prevent skin irritation, is important but not the first action. The initial focus should be on pain relief.

Choice A reason: Preparing to administer a potassium IV bolus is not typically indicated in sickle cell crisis unless there is a documented potassium deficiency. Potassium levels must be carefully monitored to avoid hyperkalemia.

Choice B reason: Providing hydration both orally and intravenously is crucial in managing sickle cell crisis. Hydration helps to reduce blood viscosity and improve circulation, which can alleviate the pain and prevent further sickling of red blood cells.

Choice C reason: Requesting a prescription for meperidine is not recommended for pain management in sickle cell crisis due to the risk of seizures and other side effects. Other pain medications, such as morphine, are preferred.

Choice D reason: Administering multiple units of platelets is not a standard treatment for sickle cell crisis. Platelet transfusion is typically reserved for patients with thrombocytopenia or active bleeding, not for sickle cell crisis.
