Question 1 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 2 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.
Question 3 of 5
A nurse is working in an outpatient studies unit administering neurological tests. The client is surprised that paste is used to secure an electroencephalogram and asks how it will be removed from the hair. With what substance does the nurse reply?
Correct Answer: C
Rationale: Shampoo is used to remove the paste, which attached the electrodes to the head. Acetone is not used on the hair. There is no special soap needed. More than warm water is needed to lift and remove the paste.
Question 4 of 5
A nurse is noting from a client's neurologic assessment findings that the client's motor impulses are interrupted from the brain to the spinal cord. It also appears that the client lacks sensory impulses from the peripheral sensory neurons to the brain. Which area has the deficit?
Correct Answer: B
Rationale: The medulla oblongata lies below the pons and transmits motor impulses from the brain to the spinal cord, and sensory impulses from the peripheral sensory neurons to the brain. The pons is part of the brainstem. The midbrain forms the forward part of the brainstem and connects the pons and the cerebellum with the two cerebral hemispheres. The subarachnoid space lies between the pie matter and the arachnoids membrane.
Question 5 of 5
A nurse is working in a neurologist's office. The physician orders a Romberg test. What should the nurse instruct the client to do?
Correct Answer: B
Rationale: In the Romberg test, the client stands erect with the feet close together and eyes closed. If the client sways as if to fall, it is considered a positive Romberg test. All of the other options include components of neurologic tests, indicating neurologic deficits and balance.
