A patient is receiving a dose of edrophonium. The nurse recognizes that this drug is given to determine the diagnosis of which disease?

Parkinson's disease

Alzheimer's disease

Myasthenia Gravis

Serotonin Syndrome

Answer and Explanation

The Correct Answer is C

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.

`To calculate the rate of infusion in mL/h, you need to divide the total volume of fluid by the total time of infusion.

In this case, you have 1,000 mL of normal saline (NS) to infuse in eight hours.

Therefore, the rate of infusion is 1,000 mL / 8 h = 125 mL/h.
