A client has recently started ferrous sulfate 500 mg by mouth two times per day for anemia. Which of the following data would indicate to the nurse that the therapy is successful?

A) Allow for rest periods between activities throughout the day: This intervention is essential for a client with activity intolerance. Incorporating rest periods helps to manage fatigue and allows for recovery, particularly when hypoxemia is a concern due to sickle cell anemia.
B) Provide supplemental oxygen when the pulse oximetry falls below 96%: Administering supplemental oxygen when oxygen saturation levels drop below 96% is crucial for preventing further hypoxemia and ensuring adequate tissue perfusion, thus addressing the client's activity intolerance.

C) Perform serial neurologic assessments to maintain safety and prevent injury: Regular neurologic assessments are vital, especially in clients with sickle cell anemia, who are at risk for complications like stroke. This intervention helps monitor for changes in neurological status, ensuring prompt action if needed.

D) Assess ability to perform activities of daily living (ADLs): Evaluating the client’s ability to perform ADLs provides valuable information on their functional status and helps tailor interventions to promote independence while considering their limitations due to hypoxemia.

E) Monitor blood pressure, pulse, and respirations after activity: This monitoring is important to evaluate the client’s response to activity and to detect any changes that could indicate distress or worsening hypoxemia. This information helps guide further interventions and ensures the client’s safety.

A) Maintain IV fluid infusion and assess adequacy of hydration: This is the best nursing action as adequate hydration is crucial in managing sickle cell crisis. It helps to reduce blood viscosity and prevent further sickling of red blood cells, which is especially important in the context of pneumonia, as dehydration can exacerbate the crisis.

B) Provide continuous sedation for pain relief: While managing pain is essential, continuous sedation is not the most appropriate first step in this situation. Pain management should be addressed, but hydration and treating the underlying causes (like pneumonia) take priority.

C) Insert an indwelling (Foley) catheter and monitor hourly urinary output: While monitoring urinary output can be important, it is not the most immediate action in this case. Focus should be on hydration and addressing the sickle cell crisis rather than on urinary output at this time.

D) Prepare for endotracheal intubation and ventilatory support: Although respiratory distress is a concern with pneumonia, the current pulse oximetry reading of 96% indicates adequate oxygenation at this time. Preparing for intubation should not be the first action unless the patient shows signs of respiratory failure or severe distress.
