Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
A patient is helped into a dorsal recumbent position so they may be examined by a medical assistant. The patient is positioned in this posture by lying face up, with the feet flat on the table and the legs bent.
The dorsal recumbent position is used for preparation for an exam like vaginal examinations, using obstetric forceps, and other operations. The patient is positioned on their back with their lower limbs flexed and turned outward. It is one of the frequently utilized dorsal or supine postures in clinical practices. Additionally, the terms "supine posture" and "dorsal recumbent position" are sometimes interchanged. To be more specific though, there is little distinction between the two locations.

<u>A temporary worsening of the condition</u> indicate that the client is in cholinergic crisis.
An edrophonium injection makes the client in cholinergic crisis temporarily worse. An improvement in the weakness indicates myasthenia crisis. Muscle spasms are not associated with this test.
The main test for myasthenia gravis is a blood test to look for a type of antibody (produced by the immune system) that stops signals being sent between the nerves and muscles. A high level of these antibodies usually means you have myasthenia gravis.
Flaccid paralysis worsens the paralysis caused by cholinergic crisis but strengthens the muscle response in the case of myasthenia gravis.
