The nurse knows that which of the following phenomena listed below is an accurate statement about axonal transport - Materials can be transported to the nerve terminal by either a fast or slow component An adult male has a new diagnosis of Guillain Barre syndrome. The nurse knows which of the following pathophysiological processes underlie the deficits that accompanied the degeneration of myelin in his peripheral nervous system - Unless re-myelination occurs the axon will eventually die While assessing a critically ill patient in the emergency department the nurse notes on the cardiac monitor an R on T premature ventricular beat that develops into ventricular tachycardia. Immediately the patient became unresponsive. The nurse knows that based on the pathophysiologic principles the most likely cause of this unresponsiveness is - Interruption of the blood/oxygen supply to the brain When educating a patient about to undergo a pacemaker insertion the nurse explains the normal phases of cardiac muscle tissue.

Therefore when explaining this to a group of nursing students the nurse will state that - The combination of GABA with the receptor site is inhibitory since it causes the local nerve membrane to become hyper polarized and less excitableWhen reviewing the purpose/action of neurotransmitters as they interact with different receptors the nurse instructor gives an example using acetylcholine.
