A nurse is caring for a client at an outpatient clinic. Select the 2 diagnostic tests the nurse should anticipate the provider to prescribe.

Rationale: A. Cerebrospinal fluid electrophoresis: CSF electrophoresis is used to detect oligoclonal bands, which are indicative of multiple sclerosis (MS). The client’s presentation—fatigue, intermittent muscle weakness, tremors, double vision, and gait disturbances—suggests a demyelinating disorder, making this test appropriate. B. Paracentesis: Paracentesis is used to evaluate ascites, which is not indicated in this client. There are no signs of abdominal fluid accumulation or liver disease that would warrant this procedure. C. Bone marrow biopsy: Bone marrow biopsy is used for hematologic disorders such as anemia, leukemia, or other blood dyscrasias. The client’s symptoms do not indicate a primary bone marrow pathology. D. MRI of brain: MRI is the diagnostic imaging of choice for detecting lesions in the central nervous system consistent with multiple sclerosis. It helps visualize demyelination and correlate it with clinical symptoms. E. X-ray of abdomen: Abdominal X-ray is not indicated, as the client does not present with abdominal pain, obstruction, or gastrointestinal issues requiring imaging.
