Nervous system review questions

This guide is our nursing test bank for NCLEX practice questions with over 3, items from a wide range of nursing topics! Also in this guide is an overview of the NCLEX, understanding what it is and how it is administered is your first step on your way to becoming a registered nurse. NCLEX stands for National Council Licensing Examinationit is a test to determine if the candidate possesses the minimum level of knowledge necessary to perform safe and effective entry-level nursing care.

The initial step in the registration process is to submit your application to the state board of nursing in the state in which you intend to obtain licensure. Inquire with your board of nursing regarding the specific registration process as requirements may vary from state to state.

Once you have received the confirmation from the board of nursing that you have met all of their state requirements, proceed, register, and pay the fee to take the NCLEX with Pearson VUE. Follow the registration instructions and complete the forms precisely and accurately.

You must test within the validity dates an average of 90 days on the ATT. Your ATT contains critical information like your test authorization number, validity date, and candidate identification number. The next step is to schedule a testing date, time, and location at Pearson VUE. The NCLEX will take place at a testing centeryou can make an exam appointment online or by telephone.

You will receive a confirmation via email of your appointment with the date and time you choose including the directions to the testing center.

You can change your appointment to test via Pearson VUE or by calling the candidate services. Rules for schedulingrescheduling, and unscheduling are explained further here.

Arrive at the testing center on your exam appointment date at least 30 minutes before the schedule. You will receive your official results from the board of nursing after six weeks. Every time you answer a question, the computer reevaluates your ability based on all the previous answers and difficulty of those test items. Your first question is relatively easy, if you selected a correct answer, the computer supplies you with a more difficult question from its question bank.

If you have selected an incorrect answer, the computer gives you an easier question. This process continues throughout the examination until the test plan requirements are met and the computer is able to determine your level of competence. Additionally, there is no option to skip a question, you must answer it or the test will not move on.

You cannot go back and review previous questions and change answers. It is a summary of the content and scope of the NCLEX to serve as a guide for candidates preparing for the exam and to direct item writers in the development of items. Some of these categories are divided further into subcategories. There are two subcategories under Safe and Effective Care Environment. There are four subcategories under Physiological Integrity.

The exam time includes all the tutorials and all the breaks. The first break is offered after two 2 hours, the second break is offered after 3. All breaks are optional and most test-takers may not need the full time to complete the examination.

When your ability is close to the passing standard, the computer continues to give you items until the maximum number of items is reached.

If your final ability estimate is above the passing standard, you pass; if it is below, you fail. If you have not answered the minimum number of required questions, you fail. If you have at least answered the minimum amount of items, the computer reviews your last 60 questions. If your ability estimate was consistently above the passing standard on the last 60 questions, you pass.

If your ability dropped below the passing standard, even once, during your last 60 questions, you fail. Regardless of the total number of questions you answer, you are given 15 questions that are experimental pretest questions. Pretest questions are indistinguishable from other questions on the test, not indicated as such, are being tested for future examination and not counted against your score.

You may be administered multiple-choice items and questions written in alternate formats. These formats may include: multiple-response or select all that apply, fill-in-the-blank calculation, ordered response, hotspot, figure, chart or exhibit, graphic, audio, and video.

Multiple-choice questions may vary and include: audio clips, graphics, exhibits or charts.Nervous systems throughout the animal kingdom vary in structure and complexity, as illustrated by the variety of animals shown in Figure Some organisms, like sea sponges, lack a true nervous system. Neurons contain organelles common to all cells, such as a nucleus and mitochondria.

They are unique because they contain dendrites, which can receive signals from other neurons, and axons that can send these signals to other cells. Multiple sclerosis causes demyelination of axons in the brain and spinal cord. Why is this problematic? Myelin provides insulation for signals traveling along axons. Without myelin, signal transmission can slow down and degrade over time. This would slow down neuronal communication across the nervous system and affect all downstream functions.

All functions performed by the nervous system—from a simple motor reflex to more advanced functions like making a memory or a decision—require neurons to communicate with one another. While humans use words and body language to communicate, neurons use electrical and chemical signals. What is the term for protein channels that connect two neurons at an electrical synapse? How does myelin aid propagation of an action potential along an axon?

How do the nodes of Ranvier help this process? Myelin prevents the leak of current from the axon. Nodes of Ranvier allow the action potential to be regenerated at specific points along the axon. They also save energy for the cell since voltage-gated ion channels and sodium-potassium transporters are not needed along myelinated portions of the axon.

An action potential travels along an axon until it depolarizes the membrane at an axon terminal. The intracellular calcium influx causes synaptic vesicles containing neurotransmitter to fuse with the presynaptic membrane. The neurotransmitter diffuses across the synaptic cleft and binds to receptors on the postsynaptic membrane. Depending on the specific neurotransmitter and postsynaptic receptor, this action can cause positive excitatory postsynaptic potential or negative inhibitory postsynaptic potential ions to enter the cell.

The central nervous system is made up of the brain and spinal cord and is covered with three layers of protective coverings called meninges from the Greek word for membrane.

The outermost layer is the dura mater with the primary function for this thick layer is to protect the brain and spinal cord. The dura mater also contains vein-like structures that carry blood from the brain back to the heart. The middle layer is the web-like arachnoid mater. The last layer is the pia mater.

Authors: J.The brain and the spinal cord are the central nervous system, and they represent the main organs of the nervous system.

The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum. The regulation of homeostasis is governed by a specialized region in the brain. The coordination of reflexes depends on the integration of sensory and motor pathways in the spinal cord. The iconic gray mantle of the human brain, which appears to make up most of the mass of the brain, is the cerebrum Figure The wrinkled portion is the cerebral cortexand the rest of the structure is beneath that outer covering.

There is a large separation between the two sides of the cerebrum called the longitudinal fissure. It separates the cerebrum into two distinct halves, a right and left cerebral hemisphere. Deep within the cerebrum, the white matter of the corpus callosum provides the major pathway for communication between the two hemispheres of the cerebral cortex. Many of the higher neurological functions, such as memory, emotion, and consciousness, are the result of cerebral function. The complexity of the cerebrum is different across vertebrate species.

The cerebrum of the most primitive vertebrates is not much more than the connection for the sense of smell. The basal nuclei are responsible for cognitive processing, the most important function being that associated with planning movements.

The basal forebrain contains nuclei that are important in learning and memory. The limbic cortex is the region of the cerebral cortex that is part of the limbic systema collection of structures involved in emotion, memory, and behavior. The cerebrum is covered by a continuous layer of gray matter that wraps around either side of the forebrain—the cerebral cortex.

This thin, extensive region of wrinkled gray matter is responsible for the higher functions of the nervous system. The pattern of these folds of tissue indicates specific regions of the cerebral cortex. The head is limited by the size of the birth canal, and the brain must fit inside the cranial cavity of the skull.

Extensive folding in the cerebral cortex enables more gray matter to fit into this limited space. If the gray matter of the cortex were peeled off of the cerebrum and laid out flat, its surface area would be roughly equal to one square meter. The folding of the cortex maximizes the amount of gray matter in the cranial cavity.

The surface of the brain can be mapped on the basis of the locations of large gyri and sulci. Using these landmarks, the cortex can be separated into four major regions, or lobes Figure Which of these sensory modalities does not pass through the ventral posterior thalamus? Visual stimuli in the upper-left visual field will be processed in what region of the primary visual cortex?

Which location on the body has the largest region of somatosensory cortex representing it, according to the sensory homunculus? Which region of the frontal lobe is responsible for initiating movement by directly connecting to cranial and spinal motor neurons? Which extrapyramidal tract incorporates equilibrium sensations with motor commands to aid in posture and movement? Which region of gray matter in the spinal cord contains motor neurons that innervate skeletal muscles?
