• A patient is on a ventilator post a car accident. What region of the spine ismost likely
damaged?
, Answer: C03-C05
• A patient is on a ventilator post a car accident. What nerve is most likelydamaged?
Answer: phrenic
• A patient damaged the radial nerve. What action is most likely limited?
Answer: -wrist extension
• A patent is not able to extend his left wrist or fingers. What nerve is mostlikely damaged?
Answer: Radial
• A patient sustained damage to their femoral nerve. What is most likelylimited?
Answer: Hip flexion, knee extension
• A patient has decreased sensation over the posterior surface of the thigh.What nerve is
most likely damaged?
Answer: sciatic
• Which of the following is true concerning the lumbar plexus?
Answer: There aretwo divisions: anterior and posterior.
• Which of the following is true concerning the brachial plexus?
Answer: There areanterior and posterior divisions.
• These contain the ganglia for the sympathetic nervous system that controls the effector
organs in the trunk, head and limbs.
Answer: Sympathetic trunk gangia
• These contain the ganglia for the parasympathetic nervous system that target the intrinsic
eye muscles to change the diameter of the pupil.
Answer: Ciliaryganglion
• Which of the following is false concerning the parasympathetic nervoussystem?
Answer: Acts to increase the heart rate.
• Which of the following is false concerning the sympathetic nervous system?
Answer: It is also called the craniosacral division.
• A patient comes into the ER following an accident. She is scared and starting to
hyperventilate. You talk with her in a calm, reassuring manner as she receives medical care.
You are trying to increase the activity in which division of her nervous system? Explain your
answer.
Answer: You are trying to increasethe activity of the parasympathetic nervous system as it is also
sometimes called the "housekeeper system" because it promotes all the internal responses we
associatewith a relaxed state. The parasympathetic system also acts to slow the heart rate.
