| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What are the key components of a focused neurological exam? | The key components include assessment of mental status, cranial nerves, motor function, sensory function, reflexes, coordination, and gait. | Think of the neuro exam as a systematic checklist covering all nervous system parts. |
| 2 | How do you evaluate a patient's mental status during the neurological exam? | Assess orientation (person, place, time), attention, memory, language, and higher cognitive functions through conversational tasks and specific questions. | Start with simple questions to gauge overall mental alertness. |
| 3 | Which cranial nerve is tested by assessing the patient's ability to read and identify objects? | Cranial Nerve II (Optic nerve). | — |
| 4 | How do you test cranial nerve III (Oculomotor), IV (Trochlear), and VI (Abducens)? | Assess eye movements in all directions, check for ptosis, and pupillary light reflexes to evaluate these nerves collectively. | — |
| 5 | What is the significance of testing pupillary reflexes in a neuro exam? | Pupillary reflexes assess the integrity of the afferent (optic nerve) and efferent (oculomotor nerve) pathways, indicating brainstem function. | — |
| 6 | Describe how to test cranial nerve V (Trigeminal). | Test facial sensation in three regions (forehead, cheeks, jaw) and assess jaw strength by asking the patient to clench their jaw against resistance. | — |
| 7 | How is cranial nerve VII (Facial nerve) evaluated? | Ask the patient to smile, frown, raise eyebrows, puff cheeks, and close eyes tightly to assess facial muscle function. | — |
| 8 | Which cranial nerve is responsible for hearing, and how is it tested? | Cranial Nerve VIII (Vestibulocochlear). Test with Weber and Rinne tuning fork tests or assess the patient's ability to hear spoken words. | — |
| 9 | What motor functions are evaluated in a neurological exam? | Muscle bulk, tone, strength (graded 0-5), and involuntary movements are assessed to identify weakness, spasticity, or tremors. | — |
| 10 | How do you test muscle strength during the neuro exam? | Perform specific movements against resistance, grading strength from 0 (no movement) to 5 (normal strength) in major muscle groups. | — |
| 11 | What sensory modalities are tested in a neurological exam? | Light touch, pinprick, temperature, vibration, proprioception, and two-point discrimination. | — |
| 12 | Describe the procedure for testing light touch sensation. | Use a cotton wisp or soft brush, asking the patient to indicate when they feel the touch on different areas, comparing sides. | — |
| 13 | How is proprioception tested? | Move the patient's finger or toe up and down and ask them to identify the direction of movement with their eyes closed. | — |
| 14 | What is testing for reflexes in the neuro exam? | Use a reflex hammer to test deep tendon reflexes such as patellar, Achilles, biceps, and triceps, grading reflexes from 0 to 4+. | — |
| 15 | How do you assess coordination in the neurological exam? | Perform tests like finger-to-nose, heel-to-shin, and rapid alternating movements to evaluate cerebellar function. | — |
| 16 | What gait abnormalities can indicate neurological dysfunction? | Patterns such as ataxic gait, hemiparetic gait, shuffling gait, or foot drop suggest specific cerebellar, motor, or peripheral nerve issues. | — |
| 17 | How do you evaluate a patient's cerebellar function? | Through coordination tests, gait assessment, and observing for tremors or dysmetria during finger-to-nose and heel-shin tests. | — |
| 18 | What are common signs of upper motor neuron lesions during a neuro exam? | Increased muscle tone (spasticity), hyperreflexia, clonus, and presence of Babinski sign. | — |
| 19 | What is the Babinski sign and what does it indicate? | Dorsiflexion of the big toe when the sole is stroked; indicates an upper motor neuron lesion. | — |
| 20 | How do you differentiate between sensory loss due to peripheral nerve vs. spinal cord lesions? | Peripheral nerve lesions typically cause localized sensory deficits; spinal cord lesions often produce dermatomal or more diffuse sensory loss. | — |
