Here is the case:

Samantha is a 40-year-old Amazon warehouse worker. Over the last ten months, she experienced diplopia and eyestrain when she read for longer than 15 minutes. She became tired after chewing her food, brushing her teeth, or drying her hair. She also became extremely fatigued at work. Despite her strong work ethic, Samantha had to excuse herself from work activities because she simply could not carry the heavy equipment.

Samantha has myasthenia gravis.

1.Why does myasthenia gravis cause muscle fatigue? What are the types of muscle fibers and which fatigue the fastest?

2.Which receptors are involved in initiation and propagation of the muscle action potential? How do ions (like sodium and potassium) move across (inside/outside the cell) the sarcolemma during an action potential?

3.Explain why the following drugs may not be appropriate for treating myasthenia gravis.

a.Botulinum toxin

b.Curare

c.Hemicholinium

This case will focus specifically on endocrine and neural drug treatment.

Prompt: Consider the following scenario: Bill, age 70, came to the examination accompanied by his wife. Bill was tall and cheerful, greeted the doctor warmly, and then started walking around the room a bit until he realized he was supposed to sit down.

 As the physician asked Bill questions for the history, he answered some, and smiled at all of the questions. Bill’s wife, Cecilia, filled in the answers that Bill was not sure of. Both Bill and Cecilia seemed to be used to her supportive role in helping Bill remember things.

Bill had retired as an accountant two years earlier. In the period since retirement, Bill had reached the point that he could not balance his checkbook. Cecilia handled that task, as well as handling money and change while shopping. This change in Bill’s use of numbers was so sudden, she said, that she wondered if something could be done to help Bill.

Bill smiled at both Cecilia and the doctor, and shrugged his shoulders.

After doing a thorough physical exam, a psychometric evaluation, and a cranial MRI, the final diagnosis was Alzheimer’s disease.

The doctor ordered some medications specifically for this disease. An anticholinergic was prescribed to cure the disease. The physician also ordered vitamins B1, B6, B12, and E. Nutritional support, physical exercises, cognitive activities, safety precautions, and other suggestions were recommended.

 In a short paper, the following critical elements must be addressed:

● Identify the incorrect medication/drug classification/treatment and explain why it is incorrect.

● What drug classification would you use instead? Why?

● Provide an example of a generic medication from each drug classification. How would each of the medications/treatments in the scenario act on the patient’s body?
