A nurse notes that a client's serum potassium level is 6 mEq/L. The nurse interprets this as an expected finding in the client with which health problem?
Cushing's
Diabetes insipidus
Addison's
Diarrhea
The Correct Answer is C
Choice A Reason: Cushing's is not an expected health problem in a client with high potassium level, as it causes low potassium level due to excess cortisol and aldosterone production.
Choice B Reason: Diabetes insipidus is not an expected health problem in a client with high potassium level, as it causes low potassium level due to excessive water loss and dilution of blood.
Choice C Reason: Addison's is an expected health problem in a client with high potassium level, as it causes high potassium level due to insufficient cortisol and aldosterone production.
Choice D Reason: Diarrhea is not an expected health problem in a client with high potassium level, as it causes low potassium level due to excessive fluid and electrolyte loss.
