Chapter 36 : Introduction to the Nervous System Questions
Question 1 of 5
The nurse is instructing a community class when a student asks, 'How does someone get super strength in an emergency?' The nurse should respond by describing the action of the:
Correct Answer: B
Rationale: The division of the autonomic nervous system called the sympathetic nervous system regulates the expenditure of energy. The neurotransmitters of the sympathetic nervous system are called catecholamines. During an emergency situation or an intensely stressful event, the body adjusts to deliver blood flow and oxygen to the brain, muscles, and lungs that need to react in the situation. The musculoskeletal system benefits from the sympathetic nervous system as the fight-or-flight effects pump blood to the muscles. The parasympathetic nervous system works to conserve body energy not expend it during an emergency. The endocrine system regulates metabolic processes.
Question 2 of 5
The nurse who is employed in a neurologist's office is performing a history and assessment on a client experiencing hearing difficulty. The nurse is most correct to gather equipment to assess the function of which cranial nerve?
Correct Answer: C
Rationale: There are 12 pairs of cranial nerves. Cranial nerve VIII is the vestibulocochlear or auditory nerve responsible for hearing and balance. Cranial nerve II is the optic nerve. Cranial nerve VI is the abducens nerve responsible for eye movement. Cranial nerve XI is the accessory nerve and is involved with head and shoulder movement.
Question 3 of 5
The nurse is caring for a client in the emergency department with a diagnosis of head trauma secondary to a motorcycle accident. The nurse aide is assigned to clean the client's face and torso. Which action by the nurse aide would prompt the nurse to provide further instruction?
Correct Answer: B
Rationale: Further instruction would be provided to the nurse aide when the nurse aide attempted to move the client's head to clean behind the ears. There should be no movement of the client's head when there is a history of head trauma. Cleaning the client's face with soapy water, cleaning the eye area, and cleaning the neck and upper chest are all appropriate actions completed by the nurse aide.
Question 4 of 5
Which diagnostic procedure would the nurse anticipate performing first if the goal was to obtain a thin 'slice' of a muscular body area?
Correct Answer: A
Rationale: A computer tomography scan uses x-rays and computer analysis to produce three-dimensional views of cross sections, or 'slices,' of the body. An MRI uses radiofrequency waves to produce images of tissue. PET scans use radioactive substances to examine metabolic activity and organ involvement. SPECT is an imaging tool that examines cerebral blood flow.
Question 5 of 5
The nurse assists the health care provider (HCP) in completing a lumbar puncture (LP). Which should the nurse note as a concern?
Correct Answer: C
Rationale: The CSF is normally clear and colorless; therefore, CSF that is cloudy would be noted by the nurse as a concern. The HCP is correct to maintain aseptic procedure. At 90 mm H2O, the client's CSF fluid pressure falls within normal limits (between 80 and 100 mm H2O). Sometimes the HCP will administer medication via intrathecal injection during an LP, which should not be a cause for concern.
