Order: 1,000 mL. NS to infuse in eight hours. At what rate in mL/h will you set the pump?

A. Parkinson's disease

Edrophonium is not used for the diagnosis of Parkinson's disease. Parkinson's disease is a neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, and bradykinesia. The diagnosis is typically based on clinical symptoms and neurological examination.

B. Alzheimer's disease

Edrophonium is not used for the diagnosis of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder affecting cognition. The diagnosis involves clinical evaluation, cognitive assessments, and sometimes imaging studies, but not the use of edrophonium.

C. Myasthenia Gravis

This is the correct choice. Edrophonium is used as a diagnostic tool in Myasthenia Gravis. In individuals with Myasthenia Gravis, the administration of edrophonium can lead to a temporary improvement in muscle strength, helping to confirm the diagnosis.

D. Serotonin Syndrome

Edrophonium is not used for the diagnosis of serotonin syndrome. Serotonin syndrome is a condition caused by an excess of serotonin, often due to the use of certain medications. Diagnosis is based on clinical symptoms and a history of serotonin-affecting medications, not the administration of edrophonium.

A. Increase the amount of dopamine and reduce the amount of acetylcholine:

This is the correct answer. Parkinson's disease is characterized by a deficiency of dopamine, so medications aim to increase dopamine levels. Additionally, reducing the activity of acetylcholine helps to restore the balance between these neurotransmitters.

B. Increase the amount of dopamine and acetylcholine:

This is not accurate. Increasing both dopamine and acetylcholine would not address the underlying imbalance seen in Parkinson's disease.

C. Reduce the amount of dopamine and increase the amount of acetylcholine:

This is incorrect. Parkinson's disease involves a reduction in dopamine levels, so reducing dopamine further would worsen the symptoms. Additionally, increasing acetylcholine is not the therapeutic goal in Parkinson's disease.

D. Reduce the amount of dopamine and acetylcholine:

This is not the correct approach. Decreasing both dopamine and acetylcholine would exacerbate the symptoms of Parkinson's disease, as the primary issue is the deficiency of dopamine.
