NR509 Advanced Physical Assessment Final Exam Review
2026/2027 Chamberlain Comprehensive Questions with
Verified Answers & Detailed Rationales Grade A Prep
1. A patient presents with loss of smell. The NP should suspect dysfunction of which
cranial nerve?
A. CN I (Olfactory)
B. CN II (Optic)
C. CN V (Trigeminal)
D. CN VII (Facial)
Correct Answer: CN I (Olfactory)
Rationale: Cranial nerve I (olfactory) is responsible for the sense of smell; dysfunction
can result in anosmia (loss of smell).
2. A patient presents with ptosis, anisocoria, diplopia, and a dilated pupil. The NP
should suspect dysfunction of which cranial nerve?
A. CN II (Optic)

B. CN III (Oculomotor)
C. CN IV (Trochlear)
D. CN VI (Abducens)
Correct Answer: CN III (Oculomotor)
Rationale: Cranial nerve III (oculomotor) controls eyelid elevation, pupillary constriction,
and most eye movements. Dysfunction causes ptosis, anisocoria, diplopia, and dilated
pupil.
3. A patient reports vertical diplopia and difficulty looking downward and inward. The
NP should suspect dysfunction of which cranial nerve?
A. CN III (Oculomotor)
B. CN IV (Trochlear)
C. CN VI (Abducens)
D. CN V (Trigeminal)
Correct Answer: CN IV (Trochlear)
Rationale: Cranial nerve IV (trochlear) innervates the superior oblique muscle, which
controls downward and inward eye movement. Dysfunction causes vertical diplopia.

4. A patient presents with loss of facial sensation and difficulty chewing. The NP
should suspect dysfunction of which cranial nerve?
A. CN V (Trigeminal)
B. CN VII (Facial)
C. CN IX (Glossopharyngeal)
D. CN XII (Hypoglossal)
Correct Answer: CN V (Trigeminal)
Rationale: Cranial nerve V (trigeminal) provides facial sensation and motor innervation
to the muscles of mastication.
5. A patient is unable to abduct the eye laterally. The NP should suspect dysfunction of
which cranial nerve?
A. CN III (Oculomotor)
B. CN IV (Trochlear)
C. CN VI (Abducens)
D. CN II (Optic)
Correct Answer: CN VI (Abducens)
Rationale: Cranial nerve VI (abducens) innervates the lateral rectus muscle, which
abducts the eye.
