1. Which lobe of the brain is responsible for motor function,
problem-solving, memory, judgment, and impulse control?
A. Parietal lobe
B. Temporal lobe
C. Frontal lobe
D. Occipital lobe
Correct ,,,,answer,,,: C. Frontal lobe
Rationale: The frontal lobe is responsible for higher executive functions
including motor function, problem-solving, memory, judgment, and
impulse control. The parietal lobe integrates sensory information, the
temporal lobe interprets smells, sounds, and language, and the occipital
lobe processes vision .
,2. A nurse is assessing a client's cranial nerves. Which client action
indicates that Cranial Nerve I (Olfactory) is intact?
A. The client can stick their tongue out
B. The client can smile symmetrically
C. The client can hear whispered words
D. The client can identify a minty scent
Correct ,,,,answer,,,: D. The client can identify a minty scent
Rationale: Cranial Nerve I (Olfactory) controls the sense of smell. To
test this nerve's function, the nurse should ask the client to identify a
non-irritating aroma such as mint or coffee .
3. Which cranial nerve is assessed by asking the client to clench their
jaw and assessing light touch on the forehead, facial skin, and scalp?
A. CN V - Trigeminal
B. CN VII - Facial
C. CN IX - Glossopharyngeal
D. CN XII - Hypoglossal
Correct ,,,,answer,,,: A. CN V - Trigeminal
Rationale: The Trigeminal nerve (CN V) has both motor function
(chewing and clenching jaw) and sensory function (forehead, facial skin,
scalp). Assessment includes clenching jaw and cotton light touch on
facial areas .
,4. Which of the following indicates Cranial Nerve VII (Facial) is
intact?
A. The client can stick out their tongue
B. The client can smile symmetrically
C. The client can hear whispered words
D. The client can identify a minty scent
Correct ,,,,answer,,,: B. The client can smile symmetrically
Rationale: Cranial Nerve VII (Facial) controls facial expression. To test
this nerve's function, the nurse should ask the client to smile, frown,
raise their eyebrows, or puff out their cheeks while checking for
symmetry .
5. Which cranial nerve is responsible for hearing and sense of
balance?
A. CN V - Trigeminal
B. CN VII - Facial
C. CN VIII - Acoustic
D. CN IX - Glossopharyngeal
Correct ,,,,answer,,,: C. CN VIII - Acoustic
Rationale: The Acoustic nerve (CN VIII) is responsible for hearing and
sense of balance. Assessment includes Weber and Rinne tests and the
whisper test .
, 6. A nurse is performing a neurological assessment and notes
decorticate posturing in a client. This finding indicates:
A. Normal neurological function
B. Brain injury
C. Spinal cord injury
D. Muscle weakness
Correct ,,,,answer,,,: B. Brain injury
Rationale: Decorticate posturing (arms flexed inward and bent toward
the body with legs extended) indicates brain injury. Decerebrate
posturing (neck extended, jaw clenched, arms pronated and extended) is
a more ominous sign of brain stem damage .
7. A client with a Glasgow Coma Scale (GCS) score of 3 would be
classified as:
A. Mild brain injury
B. Moderate brain injury
C. Severe brain injury
D. Normal neurological function
Correct ,,,,answer,,,: C. Severe brain injury
Rationale: The Glasgow Coma Scale assesses consciousness. The
lowest possible score is 3 (indicating severe brain injury), and the
highest is 15 (indicating normal neurological function). A score of 13-15
is mild, 9-12 is moderate, and 3-8 is severe .
