Answer:
Action potential in a motor neuron triggers the release of acetylcholine (ACh) neurotransmitter.
Explanation:
Acetylcholine: It is a neurotransmitter released by motor neurons which bind to the receptors end plates of the motor. When an action potential travel down the motor neuron's axon, neurotransmitter release occurs resulting in an influx of calcium and altered permeability of the synaptic terminal membrane.
The Ca2+ ions allow synaptic vesicles to move and bind with the presynaptic membrane which is present on the neuron and released neurotransmitter from the vesicles into the synaptic cleft. Once it's released ACh diffusion occurs across the synaptic cleft to the motor end plate, and binds with ACh receptor. As the neurotransmitter ACh binds, these ions channel open and sodium ions cross the membrane into the muscle cells.
In this phase reduction of voltage inside and outside the cell occurs, which is known as depolarization. When ACh binds to the motor end plate this depolarization is known as end plate potential. Then depolarization spread with the sarcolemma and creating an action potential. This action potential moves the entire cell and creating a wave of depolarization.
The correct answer is that "for most clients, surgery is recommended only if non-surgical treatments have been unsuccessful." This is because of the guidelines involving medicine and surgery as well as guidelines involving the treatment of colitis. The question should have specified what type of colitis is the patient having, whether infectious or autoimmune. In infectious colitis, then surgery almost has no role and medical treatment with antibiotics as well as supportive therapy and fluid replacement are the only ones needed. In autoimmune colitis such as Crohn's disease or ulcerative colitis, while immunosuppressor drugs may have a role, surgery may be the mainstay of treatment especially those who are at risk of malignant degeneration.

Saline solutions have the same or close to the same amount of salt as our blood does, so we get the amount of salt needed for our bodies. During blood loss, you lose the salt you need, so they're basically adding it back in with the saline solution, making your electrolyte balance go back to normal level. It also gives us the right amount of water to keep us hydrated.
