(Latest ) Questions with Verified Answers - Chamberlain




1. While assessing a client's cranial nerves, the nurse asks the client to identify a

familiar smell with eyes closed. This tests which cranial nerve?

A. Optic (CN II)

B. Olfactory (CN I)

C. Trigeminal (CN V)

D. Facial (CN VII)

CORRECT ANSWER: B

Rationale: Cranial Nerve I (Olfactory) is responsible for the sense of smell. Testing

involves having the client identify familiar, non-irritating odors with each nostril

separately.

2. The nurse is assessing a client's visual fields using confrontation. This

examination primarily evaluates the function of which cranial nerve?

A. Oculomotor (CN III)

B. Trochlear (CN IV)

C. Optic (CN II)

D. Abducens (CN VI)

CORRECT ANSWER: C

Rationale: Cranial Nerve II (Optic) is responsible for visual acuity and visual fields.

The confrontation test is a gross screening measure for peripheral vision defects.

3. The nurse observes a client has ptosis (drooping) of the eyelid and that the eye

is deviated downward and outward. This finding suggests an issue with which

cranial nerve?

A. Trochlear (CN IV)

B. Abducens (CN VI)

C. Oculomotor (CN III)

D. Facial (CN VII)

CORRECT ANSWER: C

Rationale: Cranial Nerve III (Oculomotor) innervates the levator palpebrae

(elevates eyelid) and most extraocular muscles. Damage causes ptosis, dilation,

and "down and out" eye deviation.

4. A client is unable to look downward when the eye is adducted (turned inward).

The nurse suspects impaired function of which cranial nerve?

NR509

A. Oculomotor (CN III)

B. Trochlear (CN IV)

C. Abducens (CN VI)

D. Trigeminal (CN V)

CORRECT ANSWER: B

Rationale: Cranial Nerve IV (Trochlear) innervates the superior oblique muscle,

which primarily moves the eye downward when it is turned inward.

5. During a neurological exam, the nurse tests the motor function of the

temporalis and masseter muscles by asking the client to clench their teeth. This

assesses which cranial nerve?

A. Trigeminal (CN V)

B. Facial (CN VII)

C. Glossopharyngeal (CN IX)

D. Hypoglossal (CN XII)

CORRECT ANSWER: A

Rationale: Cranial Nerve V (Trigeminal) has both sensory and motor functions. Its

motor branch innervates the muscles of mastication (temporalis, masseter,

pterygoids).

6. A client presents with difficulty abducting the right eye (looking outward). The

nurse should document a potential deficit in which cranial nerve?

A. Oculomotor (CN III)

B. Trochlear (CN IV)

C. Abducens (CN VI)

D. Facial (CN VII)

CORRECT ANSWER: C

Rationale: Cranial Nerve VI (Abducens) innervates the lateral rectus muscle,

which is responsible for abducting the eye (outward gaze).

7. The nurse is assessing a client's facial symmetry. Asking the client to smile,

frown, and puff out their cheeks tests the function of which cranial nerve?

A. Trigeminal (CN V)

B. Facial (CN VII)

C. Vestibulocochlear (CN VIII)

D. Glossopharyngeal (CN IX)

CORRECT ANSWER: B

Rationale: Cranial Nerve VII (Facial) controls the muscles of facial expression.

Testing includes observing for symmetry during various movements like smiling

and eye closure.
