Answer:
A.
Step-by-step explanation:
In a client with Addison's disease who presents with symptoms such as nausea, vomiting, diarrhea, and abdominal pain, it is crucial to prevent an addisonian crisis. Addison's disease is characterized by the body's inability to produce adequate amounts of cortisol (a type of steroid hormone). During times of stress or illness, the body requires increased cortisol levels to respond effectively.
Therefore, the nurse should expect the provider to prescribe hydrocortisone, a synthetic form of cortisol, to replace the deficient hormone and prevent an addisonian crisis in response to the stress and symptoms the client is experiencing. This medication helps to stabilize the client's condition and maintain proper hormonal balance.
