1. A 45-year-old man reports tingling sensations affecting both hands and feet, along with weakness. He describes the tingling as spontaneous burning and pins-and-needles sensations that occur without any external stimulus. Which term best describes this symptom?
- AAllodynia
- BHyperpathia
- CDysesthesia
- DParesthesia
Show answer
D. Paresthesia Paresthesia is defined as abnormal spontaneous sensations such as burning, tingling, or pins and needles, distinguishing it from dysesthesia which requires an external stimulus.
2. A 38-year-old woman reports numbness affecting all four limbs, symmetric in distribution, without weakness. She has recently been under significant stress. Based on the pattern of symptom distribution described, which of the following is a plausible cause to consider?
- AThoracic outlet syndrome
- BA hemispheric lesion
- CHyperventilation syndrome
- DA discrete root lesion
Show answer
C. Hyperventilation syndrome The text states that sensory disturbances involving all the limbs suggest peripheral neuropathy, a cervical cord or brainstem lesion, or a metabolic disturbance such as hyperventilation syndrome.
3. A 55-year-old man with suspected tabes dorsalis is asked to stand with feet together, arms outstretched, and eyes closed. He remains steady with eyes open but becomes markedly unsteady and nearly falls when his eyes are closed. What does this finding, and the underlying deficit it reflects, indicate?
- AA negative Romberg test, indicating normal proprioception
- BA positive Romberg test, indicating loss of pain and temperature sensation
- CA positive Romberg test, indicating cerebellar dysfunction
- DA positive Romberg test, indicating grossly impaired joint position sense in the legs
Show answer
D. A positive Romberg test, indicating grossly impaired joint position sense in the legs The text explains that a positive Romberg test occurs when unsteadiness is markedly increased by eye closure, as in tabes dorsalis, and indicates grossly impaired joint position sense in the legs.
