Cranial Nerves Nursing Exam 2026/2027
INTRODUCTION
This comprehensive Cranial Nerves Nursing Exam for 2026/2027 provides 75 expertly crafted,
evidence-based questions with verified correct answers and detailed rationales. The exam covers all
twelve cranial nerves (CN I through CN XII) across nine systematically organized sections,
progressing from foundational anatomy and function through clinical assessment, emergency
recognition, documentation, patient safety, and NCLEX-RN prioritization strategies. Each question is
designed to strengthen the clinical judgment competencies required for safe, competent neurological
nursing practice and successful licensure examination performance.
Content is aligned with authoritative clinical guidelines from the American Heart Association (AHA)
Stroke Guidelines, the National Institutes of Health Stroke Scale (NIHSS), the National Council of
State Boards of Nursing (NCSBN) Clinical Judgment Measurement Model (CJMM), and ATI
Neurological Nursing Modules. Questions address cranial nerve anatomy, functional classification
(sensory, motor, mixed), brainstem origin, foramina of exit, systematic assessment techniques
(PERRLA, EOMI, Weber/Rinne, gag reflex, tongue protrusion, shoulder shrug), visual and facial
assessment, lower cranial nerve evaluation, neurological emergency recognition (increased ICP,
Cushing’s triad, uncal and tonsillar herniation), documentation standards, patient safety, and NCLEX
prioritization strategies.
For optimal preparation, candidates should practice applying the ABC-neurological prioritization
framework systematically, understanding that cranial nerve deficits can signal life-threatening
conditions requiring immediate intervention. When approaching NCLEX neurological questions,
remember: airway protection (CN IX/X) always takes priority; uncal herniation (CN III compression)
is a neurosurgical emergency; and the ABCs framework supersedes all other prioritization models in
acute neurological deterioration. This exam has been graded A+ with 100% verification of all answers
and rationales against current evidence-based nursing practice standards.
Section 1: Cranial Nerve Anatomy & Function Review
CN I through CN XII — Classification, Origin, and Pathways
1. The nurse is reviewing cranial nerve anatomy. Which cranial nerve is classified as purely
sensory?
A) Oculomotor nerve (CN III)
B) Trigeminal nerve (CN V)
C) Olfactory nerve (CN I)
D) Vagus nerve (CN X)

Cranial Nerves Nursing Exam 2026/2027
Rationale: The olfactory nerve (CN I) is a purely sensory nerve responsible for the sense of smell. The cranial
nerves are classified as sensory, motor, or mixed (both sensory and motor). CN I, CN II (optic), and CN VIII
(vestibulocochlear) are the three purely sensory cranial nerves. CN III (A) is a motor nerve controlling most
extraocular muscles and the pupillary sphincter. CN V (B) is a mixed nerve providing facial sensation and
motor function for mastication. CN X (D) is a mixed nerve with extensive parasympathetic and motor functions.
2. A nursing student is learning the cranial nerve mnemonic. Which cranial nerve pair is
responsible for the sense of smell and the sense of vision, respectively?
A) CN I and CN II
B) CN II and CN III
C) CN III and CN IV
D) CN IV and CN VI
Rationale: CN I (olfactory nerve) is responsible for the sense of smell, and CN II (optic nerve) is responsible for
the sense of vision. These two cranial nerves are the first pair in the traditional mnemonic and are both purely
sensory. CN III (B, C) is the oculomotor nerve responsible for eye movement and pupillary constriction. CN IV
(C, D) is the trochlear nerve controlling the superior oblique muscle. CN VI (D) is the abducens nerve
controlling lateral rectus. The mnemonic 'On Old Olympus' Towering Tops A Finn And German Viewed Some
Hops' aids in recalling CN I through CN XII in order.
3. Which cranial nerve exits the skull through the jugular foramen?
A) Oculomotor nerve (CN III)
B) Trigeminal nerve (CN V)
C) Facial nerve (CN VII)
D) Glossopharyngeal nerve (CN IX)
Rationale: The glossopharyngeal nerve (CN IX) exits the skull through the jugular foramen, along with CN X
(vagus) and CN XI (spinal accessory). These three cranial nerves share this anatomical exit point. CN III (A)
exits through the superior orbital fissure. CN V (B) has three branches exiting through different foramina: V1
through the superior orbital fissure, V2 through the foramen rotundum, and V3 through the foramen ovale. CN
VII (C) exits through the internal acoustic meatus along with CN VIII.
4. The nurse is assessing a patient who reports loss of the sense of smell following a head injury.
Which cranial nerve was most likely affected?
A) CN I (Olfactory)
B) CN II (Optic)
C) CN III (Oculomotor)
D) CN IV (Trochlear)
Rationale: The olfactory nerve (CN I) is responsible for the sense of smell. Anosmia (loss of smell) commonly
occurs after head trauma due to shearing of the olfactory nerve fibers as they pass through the cribriform plate
of the ethmoid bone. The cribriform plate is thin and fragile, making it susceptible to fracture during frontal
head injuries. CN II (B) is the optic nerve for vision. CN III (C) controls eye movement and pupil constriction.
CN IV (D) controls the superior oblique muscle for downward and inward eye movement.
