  • What are the two divisions of the autonomic nervous system?
    The two divisions of the autonomic nervous system are the sympathetic and parasympathetic divisions.
  • What causes vasodilation of arterioles?
    Parasympathetic activation
  • Where is the vasomotor center located?
    The vasomotor center is located in the medulla oblongata of the brainstem.
  • Which nursing intervention can prevent a client from experiencing autonomic dysreflexia?
    Ensuring the bladder is emptied regularly and monitoring for bowel impaction can prevent autonomic dysreflexia.
  • What is not a function of the autonomic nervous system?
    Voluntary muscle movement
  • Which muscles are controlled by the autonomic nervous system?
    Cardiac muscles
  • What is the primary difference between the somatic nervous system and the autonomic nervous system?
    The somatic nervous system controls voluntary movements, while the autonomic nervous system controls involuntary functions.
  • Which nursing intervention is the priority for a client in myasthenic crisis?
    Ensuring airway patency and providing respiratory support is the priority intervention.
  • Which bodily function is controlled by the autonomic nervous system?
    Breathing
  • Which interview technique should you use when addressing a geriatric patient?
    Use clear, simple language and allow extra time for responses.
  • Which actions are functions of the somatic nervous system? Check all that apply. A) Walking B) Breathing C) Heartbeat D) Reflex actions
    A) Walking, D) Reflex actions
  • Which function is not controlled by the autonomic nervous system?
    Voluntary muscle movement
  • Which adrenergic receptors increase cAMP levels?
    Beta-1, Beta-2
  • What is a clinical characteristic of neurogenic shock?
    Bradycardia
  • Which target organ receives dual innervation?
    The heart receives dual innervation from both the sympathetic and parasympathetic nervous systems.
  • What does the autonomic nervous system regulate?
    It regulates involuntary functions
  • The autonomic division of the PNS regulates the activity of which of these? A) Skeletal muscles B) Cardiac muscles C) Voluntary movements D) Reflex actions
    B) Cardiac muscles
  • What bodily functions does the autonomic nervous system regulate?
    It regulates involuntary bodily functions
  • What is a function of the somatic nervous system?
    The somatic nervous system controls voluntary muscle movements.
  • What is the appropriate nursing intervention in dealing with a suicidal client?
    Ensure the client is in a safe environment and provide constant supervision.
  • What is the difference between the somatic and autonomic nervous systems?
    The somatic nervous system controls voluntary movements, while the autonomic nervous system controls involuntary functions.
  • Which cranial nerve is not involved in the parasympathetic nervous system? A) CN III B) CN VII C) CN IX D) CN XII
    D) CN XII
  • Which nervous system regulates conscious activities?
    The somatic nervous system regulates conscious activities.
  • Which substance is not a vasoconstrictor?
    Acetylcholine
  • Which structure is not associated with the autonomic nervous system?
    D) Skeletal muscles
  • Which part of the nervous system directly controls the digestive system?
    The autonomic nervous system, specifically the parasympathetic division, directly controls the digestive system.
  • Which behavior does the nurse observe in the client with anxious or fearful personality disorder?
    The client may exhibit avoidance of social situations and excessive worry.
  • Which nursing goal is a priority when caring for a client newly diagnosed with vertigo?
    Preventing falls and ensuring safety is a priority goal.
  • What are the differences between the somatic nervous system and autonomic nervous system?
    The somatic nervous system controls voluntary movements, while the autonomic nervous system controls involuntary functions.
  • Which drug lowers blood pressure by reducing the sympathetic vasomotor response?
    A) Beta-blockers
  • What are two true characteristics of preganglionic neurons?
    They release acetylcholine and are located in the central nervous system
  • What is a characteristic of the somatic nervous system?
    Single neuron pathway
  • The nervous system can trigger vasoconstriction and vasodilation. What effect does this have?
    Vasoconstriction increases blood pressure, while vasodilation decreases blood pressure.
  • What does venoconstriction increase?
    Blood pressure
  • What is the difference between the somatic and autonomic nervous system?
    The somatic nervous system controls voluntary movements, while the autonomic nervous system controls involuntary functions.
  • What is the difference between the autonomic nervous system and the somatic nervous system?
    The autonomic nervous system controls involuntary functions, while the somatic nervous system controls voluntary movements.
  • Which is an important strategy for a patient with receptive aphasia?
    Use simple language and visual aids to enhance understanding.
