The wife of a 65 year old man tells the nurse that she is concerned because she has noticed a change in her husbands personality and ability to understand. He also cries very easily and becomes angry. The nurse recalls that the cerebral lobe responsible for these behaviors is the ______ lobe. Frontal The frontal lobe is responsible for personality, behavior, emotions and intellectual function. The parietal lobe has areas responsible for sensation. The occipital lobe is responsible for visual reception. The temporal lobe is responsible for hearing, taste and smell. 3. Which area concerning the areas of the brain is true? The hypothalamus controls body temperature and sleep. Hypothalamus functions include body temperature controller, sleep center, anterior and posterior pituitary gland regulator and coordinator of the autonomic nervous system activity and emotional status. 4. The are of the nervous system that is responsible for mediating reflexes is the : Spinal Cord 5. While gathering equipment after an injection, a nurse accidentally received a prick from an improperly capped needle. To interpret this sensation, which of these areas must be intact? Lateral spinothalamic tract, thalamus and sensory cortex. Rationale: The spinothalamic tract contains sensory fibers that transmit the sensation of pain, temperature, and crude or light touch. A patient with a lack of oxygen to his heart will have pain in his chest and possibly in the shoulder, arms and jaw. The nurse knows that the best explanation why this occurs is which statement? The sensory cortex does not have the ability to localize pain in the heart: consequently the pain is felt else where. Rationale: The sensory cortex is arranged ina specific pattern, forming a corresponding map of the body The ability that humans have to perform very skilled movements such as writting is contrlled by the : Corticospinal tract Cortispinal fibers mediate voluntary movement, particularly very skilled, discrete and purposeful movements such as writing. Also known as pyramidal tract A 30 year old women tells the nurse that she has been very unsteady and has difficulty in maintaining her balance. Which area of the brain that is related to these findings would concern the nurse? Cerebellum Rationale: The cerebellum coordinates movement, maintains equilibrium, and helps maintain posture. Which of these statements about the peripheral nervous system is correct? The peripheral nerves carry input to the central nervous system by afferent fibers away from the central nervous system by efferent fibers. A patient has a severed spinal nerve as a result of trauma. Which statement is true in this situation? The adjacent spinal nerves will continue to carry sensations for the dermatome served by the severed nerve. Rationle: A dermatome is a circumscribed skin area that is primarily supplied from one spinal cord segment through a particular spinal nerve. The dermatome overlap, which is a form of biological insurance, that is if one nerve is severed, then most of the sensations can be transmitted by the spinal nerve above and the spinal nerve below the severed nerve. A 21 year old patient has a head injury resulting in trauma and is unconscious. There are no other injuries. During the assessment what would the nurse expect to find when testing the patients deep tendon reflexes? Reflexes will be normal. A mother of a 1 month old infant asks the nurse why it takes so long for infants to learn to roll over. The nurse knows that the reason for this is: Myelin is needed to conduct impulses and the neurons of a newborn are not yet myelinated. During an assessment of an 80 year old patient, the nurse notices the following: an inability to notice vibrations at the ankles, and to identify the position of her big toe, a slower and more deliberate gait, and slightly impaired tactile sensation. All other neurological findings are normal. The nurse should interpret that these findings indicate: Normal changes attributable to aging. A 70 year old woman tells the nurse that everytime she gets up in the morning or after shes been sitting she gets really dizzy and feels like she is going to fall over. The nurses best response would be: You need to get up slowly when you've been lying or sitting. Uring the taking of a health history, a patient tells the nurse that it feels like the room is spinning around me. The
