Neuron that use Acetylcholine (ACh) as its neurotransmitter are what type of neuron?

A) Myasthenia gravis (MG):
Weakness of the extremities and diplopia (double vision) are hallmark symptoms of myasthenia gravis, an autoimmune disorder that affects the neuromuscular junction. In MG, antibodies attack acetylcholine receptors, leading to muscle weakness that worsens with activity and improves with rest. The weakness typically affects voluntary muscles, including those responsible for eye movement, which leads to symptoms such as diplopia and ptosis (drooping eyelids).

B) Multiple sclerosis (MS):
Multiple sclerosis involves the demyelination of neurons in the central nervous system, leading to a variety of neurological symptoms. While MS can cause weakness and visual disturbances, the typical symptoms of MS include fatigue, muscle spasticity, ataxia, and sensory deficits. Diplopia can occur in MS but is usually accompanied by other neurological signs such as numbness, tingling, or loss of coordination.

C) Cerebral palsy (CP):
Cerebral palsy is a group of disorders affecting movement and posture due to non-progressive brain injury or abnormal brain development, often occurring in early childhood. While CP can cause muscle weakness and coordination issues, it does not typically present with diplopia. Instead, it often involves spasticity, motor impairment, and difficulty with fine motor tasks.

D) Parkinson disease (PD):
Parkinson disease is characterized by tremors, bradykinesia (slowness of movement), rigidity, and postural instability. While PD can lead to muscle weakness and visual issues like blurred vision, it is not typically associated with diplopia as a primary symptom. The hallmark motor symptoms are primarily related to tremor and difficulty initiating movements rather than generalized weakness and double vision.

A) Stop taking the medication immediately: Abruptly stopping amitriptyline without the guidance of a healthcare provider can cause withdrawal symptoms and other complications. Discontinuing this medication should only be done under medical supervision.

B) Increase fluid intake: Amitriptyline can cause anticholinergic side effects such as dry mouth and constipation. Increasing fluid intake helps manage dry mouth by stimulating salivation and helps alleviate constipation by promoting bowel regularity.

C) Request another antidepressant: While amitriptyline can cause side effects like dry mouth and constipation, switching medications should not be the first step. These side effects are often manageable with lifestyle modifications, such as increasing fluid and fiber intake, and adjustments to the treatment plan can be considered if the symptoms are severe or persistent.

D) Notify the provider: While it is important for the nurse to document and inform the provider about any significant side effects, this instruction alone does not provide immediate relief to the patient. It is more appropriate to first recommend increasing fluid intake, and then the nurse can discuss with the provider if the symptoms persist or worsen.
