160) ANSWER

B) The client has adrenal insufficiency.

RATIONALE

In the presence of adrenal insufficiency, metyrapone can cause an adrenal crisis by stopping the synthesis of cortisol. Options 1 and 4 are the opposite of what is occurring with the client. Option 3 is an unrelated finding. Note in the question stem that the client is experiencing an adrenal crisis. Options 1, 2, and 4 can be eliminated because they are the direct opposite of the scenario in the question. Option 2 is the only option that addresses adrenal insufficiency.
