1. A patient presents with sudden focal neurologic deficits. Laboratory workup reveals an elevated platelet count and elevated hematocrit. According to the chapter, this hematologic profile increases the risk for which type of cerebrovascular event, as opposed to a patient with thrombocytopenia?
- AVenous sinus thrombosis specifically excluded from risk
- BIntracranial hemorrhage
- CIschemic stroke
- DSubarachnoid hemorrhage
Show answer
C. Ischemic stroke The text states polycythemia and thrombocytosis may predispose to ischemic stroke, whereas thrombocytopenia and coagulopathy are associated with intracranial hemorrhage.
2. A pregnant woman in her third trimester develops sudden numbness and tingling in the lateral thigh after a prolonged labor involving forceps-assisted delivery. Which of the following is the most likely explanation based on obstetric neurologic complications discussed in the chapter?
- AIdiopathic intracranial hypertension causing visual field cuts
- BCarpal tunnel syndrome due to pregnancy-related fluid retention
- CTraumatic neuropathy from pressure exerted by the fetal head or obstetric forceps affecting the lateral femoral cutaneous nerve
- DEclampsia causing generalized tonic-clonic seizures
Show answer
C. Traumatic neuropathy from pressure exerted by the fetal head or obstetric forceps affecting the lateral femoral cutaneous nerve The text specifically mentions meralgia paresthetica (lateral femoral cutaneous neuropathy) and traumatic neuropathies from fetal head or forceps pressure during delivery.
3. A 55-year-old man with a history of chronic alcoholism and poor diet presents with dementia and is found to have degeneration of both the corticospinal tracts and posterior columns of the spinal cord. Which vitamin deficiency is most consistent with this presentation?
- AVitamin B3 (niacin)
- BVitamin E (tocopherol)
- CVitamin B12 (cobalamin)
- DVitamin B1 (thiamin)
Show answer
C. Vitamin B12 (cobalamin) Vitamin B12 deficiency produces combined systems disease (degeneration of corticospinal tracts and posterior columns) and dementia (megaloblastic madness), distinguishing it from B1, B3, and E deficiencies described in the text.
