| 1. | During a late night study session, a pathophysiology student reaches out to turn the page of her textbook. Which of the following components of her nervous system contains the highest level of control of her arm and hand action? | |
| A) | Cerebellum | |
| B) | Thalamus | |
| C) | Basal ganglia | |
| D) | Frontal lobe | |
| Ans: | D | |
| Feedback: | ||
| While intentional movement involves input from various components of the nervous system including the cerebellum, thalamus, and basal ganglia, primary control and coordination are controlled by the motor cortex in the frontal lobe. | ||
| 2. | A patient is asked to stand with feet together, eyes open, and hands by the sides. Then the patient is asked to close his eyes while the nurse observes for a full minute. What assessment is the nurse performing? | |
| A) | Segmental reflex | |
| B) | Posture | |
| C) | Proprioception | |
| D) | Crossed-extensor reflex | |
| Ans: | C | |
| Feedback: | ||
| Information from the sensory afferents is relayed to the cerebellum and cerebral cortex and is experienced as proprioception or the sense of body movement and position independent of vision. The knee-jerk reflex is a form of stretch reflex. The crossed-extensor reflex serves to integrate motor movements, so they function in a coordinated manner. | ||
| 3. | A clinician is conducting an assessment of a male client suspected of having a disorder of motor function. Which of the following assessment findings would suggest a possible upper motor neuron (UMN) lesion? | |
| A) | The client has decreased deep tendon reflexes. | |
| B) | The client displays increased muscle tone. | |
| C) | The client’s muscles appear atrophied. | |
| D) | The client displays weakness in the distal portions of his limbs. | |
| Ans: | B | |
| Feedback: | ||
| UMNs typically produce increased muscle tone, while hyporeflexia, muscle atrophy, and weakness in the distal portion of limbs are more commonly indicative of LMN lesions. | ||
| 4. | The parents of a 3-year-old boy have brought him to a pediatrician for assessment of the boy’s late ambulation and frequent falls. Subsequent muscle biopsy has confirmed a diagnosis of Duchenne muscular dystrophy. Which of the following teaching points should the physician include when explaining the child’s diagnosis to his parents? | |
| A) | “Your son’s muscular dystrophy is a result of faulty connections between muscles and the nerves that normally control them.” | |
| B) | “He’ll require intensive physical therapy as he grows up, and there’s a good chance that he will outgrow this problem as he develops.” | |
| C) | “Your son will be prone to heart problems and decreased lung function because of this.” | |
| D) | “His muscles will weaken and will visibly decrease in size relative to his body size throughout his childhood.” | |
| Ans: | C | |
| Feedback: | ||
| Muscular dystrophy is associated with cardiac and respiratory complications. It does not involve the nervous system, and the problem will not dissipate with time. While muscles become weakened, pseudohypertrophy means that their size does not decrease. | ||
| 5. | The unique clinical presentation of a 3-month-old infant in the emergency department leads the care team to suspect botulism. Which of the following assessment questions posed to the parents is likely to be most useful in the differential diagnosis? | |
| A) | “Have you ever given your child any honey or honey-containing products?” | |
| B) | “Is there any family history of neuromuscular diseases?” | |
| C) | “Has your baby ever been directly exposed to any chemical cleaning products?” | |
| D) | “Is there any mold in your home that you know of?” | |
| Ans: | A | |
| Feedback: | ||
| Botulism in infants is frequently attributable to honey. Family history is not a relevant consideration given the bacterial etiology, and mold and chemical cleaning products are not known to predispose to botulism toxicity. | ||
