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.

Correct Answer is D
Explanation
Choice A Reason: Parkinson's disease does not result from too low acetylcholine as a result of an autoimmune reaction, but this may be a description of myasthenia gravis, which affects the neuromuscular junction.
Choice B Reason: Parkinson's disease is not caused by the deterioration of the myelin sheath of the basal ganglia, but this may be a description of multiple sclerosis, which affects the central nervous system.
Choice C Reason: Excess dopamine and deficient acetylcholine are not the two major causes of Parkinson's disease, but they are reversed. Parkinson's disease is caused by low dopamine and high acetylcholine levels in the brain.
Choice D Reason: Parkinson's is caused by depletion of dopamine and excess of acetylcholine, as this affects the balance between these two neurotransmitters that control movement and coordination.
