VERIFIED ANSWERS|BRAND NEW 2026-2027
UPDATE|GRADED A+
Question 1
**1.**
**Q:** What is the primary purpose of a neurologic assessment?
- A) To evaluate cognitive function
- B) To identify abnormalities in brain function
- C) To diagnose cardiovascular conditions
- D) To assess respiratory rate
CORRECT ANSWER
**A:** B) To identify abnormalities in brain function
**Rationale:** The primary purpose of a neurologic assessment is to identify
abnormalities in brain function and diagnose potential neurological disorders.
Question 2
**2.**
**Q:** Which cranial nerve is tested by asking the patient to smile or frown?
- A) Olfactory nerve (CN I)
- B) Optic nerve (CN II)
- C) Facial nerve (CN VII)
- D) Trigeminal nerve (CN V)
CORRECT ANSWER
**A:** C) Facial nerve
**Rationale:** The facial nerve (CN VII) controls facial expressions, so asking a patient to
smile or frown tests its function.

, CNI--> smell test
CN II--> visual acuity test; Pupil assessment
CN V--> trigeminal nerve's main functions are to relay sensory information from the face
and head, and to control the muscles used for biting and chewing. It has three main
branches: the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve
(V3). The ophthalmic and maxillary nerves are purely sensory, while the mandibular
nerve has both sensory and motor functions.
Question 3
**3.**
**Q:** What does the Glasgow Coma Scale (GCS) primarily assess?
- A) The patient's level of consciousness
- B) The patient's motor strength
- C) The patient's sensory perception
- D) The patient's coordination
CORRECT ANSWER
**A:** A) The patient's level of consciousness
**Rationale:** The Glasgow Coma Scale (GCS) assesses a patient's level of consciousness
based on eye, verbal, and motor responses.
Score is 3-15, more points is better for mental status.
Question 4
**4.**
2
@THE STUDY VAULT
, **Q:** What is a positive sign of the Babinski reflex in adults?
- A) Toes curl downward
- B) Toes fan out and big toe extends upward
- C) Toes remain still
- D) Toes twitch involuntarily
CORRECT ANSWER
**A:** B) Toes fan out and big toe extends upward
**Rationale:** A positive Babinski sign in adults indicates upper motor neuron
dysfunction, where the toes fan out and the big toe extends upward.
After 2 years old, the normal reaction, as described by Strümpell, is flexion of the toes
and withdrawal of the foot
Question 5
**5.**
**Q:** Which part of the neurologic examination evaluates a patient's ability to perform
smooth
coordinated movements?
- A) Reflexes
- B) Cranial nerve function
- C) Motor coordination
- D) Sensory perception
CORRECT ANSWER
**A:** C) Motor coordination
**Rationale:** Motor coordination is evaluated by testing a patient's ability to perform
smooth, coordinated movements, often assessed through tasks like finger-to-nose or
heel-to-shin. Ataxia is an abnormal finding that can happen on this assessment.
