NR 668 Week 3 Quiz 3 Nervous System and Brain Anatomy

Nervous System and Brain Anatomy The patient presents with a recent diagnosis of apraxia. What is apraxia? The inability to carry out a skilled movement despite having the physical ability to do so Lack of insight that one has a disability related to a previous CVA The inability to speak without slurring words related to parietal lobe damage Gait abnormality secondary to cerebral degeneration With apraxia, one cannot carry out a skilled movement despite the fact that one retains the physical ability to do so. This is may occur with damage to the Parietal lobe. Layla checks on her curling iron to ensure it has been shut off upwards of 8 times per day. Layla suffers from obsessive thinking.

Which cerebral lobe houses the receptive area for touch and spatial orientation? Parietal Lobe The Frontal Lobe The Temporal Lobe Occipital lobe The Parietal lobe houses the receptive area for touch and spatial orientation. The part of the neuron that takes in and receives messages is called: Dendrite Node of Ranvier Synapse Axon Your patient Abigail has suffered an infarct in the right hemisphere of her brain. What would the APRN expect to find on physical exam? Contralateral weakness Superior weakness Ipsilateral weakness Same side weakness Contralateral refers to the opposite side of the body. An infarct in the right hemisphere of the brain may produce weakness on the left side of the body.

Which neurotransmitter is associated with the symptoms? Serotonin Dopamine Gamma-aminobenzoic acid (GABA) Cannibinoids Which type of brain matter contains myelin and allows electrical signals to travel fast? Gray Matter Back Matter Yellow Matter White matter White matter allows electrical signals to travel very fast. This matter appears white due to its myelin content. The central nervous system is composed of this which of the following elements? Brain and cranial nerves Spinal cord and nerves Brain and spinal cord Cranial nerves and spinal nerves The CNS is composed of the Brain and Spinal cord. The junction between two neurons is known as the: Soma Dendrite Synapse Node of Ranvier Expressive aphasia may occur with damage in which brain location? Broca's area Occipital lobe Substantia Nigra Cerebellum Damage to Broca's area located within the frontal lobe may result in expressive aphasia. A 72-year-old man with a comorbid history of uncontrolled hypertension is referred to the PMHNP for dementia secondary to depression. The mental status exam reveals difficulty speaking fluently, inappropriate and confabulated responses, incongruent affect, and poor judgment. A cerebrovascular accident in which region
