Final answer:
The nurse will include the potential complication of infection in the care plan for a patient with idiopathic aplastic anemia.
Step-by-step explanation:
The collaborative problem that the nurse will include in the care plan for a patient admitted to the hospital with idiopathic aplastic anemia is potential complication: infection.
Aplastic anemia is a condition that occurs when the bone marrow does not produce enough new blood cells. This leads to a weakened immune system and a higher risk of infections. Therefore, it is important for the nurse to monitor the patient for any signs of infection and take appropriate measures to prevent and treat infections.
