Domain 1: Head & Face Assessment
Skull Inspection, Facial Expression & CN VII Function, Temporal Artery Palpation, TMJ Assessment,
Sinus Tenderness Evaluation
Q1. During a routine head assessment, the nurse notes that the patient's skull appears
elongated with a prominent frontal bone. This finding is most consistent with which of the
following?
A. Scaphocephaly (sagittal craniosynostosis)
B. Brachycephaly (coronal craniosynostosis)
C. Plagiocephaly (unilateral coronal synostosis)
D. Hydrocephalus
Rationale: Scaphocephaly, also called dolichocephaly, results from premature fusion of the sagittal
suture, producing a long, narrow skull with prominent frontal and occipital regions. Brachycephaly
results from coronal synostosis producing a wide, short skull. Plagiocephaly produces asymmetric
flattening. Hydrocephalus causes overall head enlargement with a bulging fontanelle in infants, not
elongation.
Q2. When assessing facial expression and movement, the nurse asks the patient to smile,
frown, raise eyebrows, and puff out the cheeks. Which cranial nerve is being primarily
evaluated?
A. Cranial nerve V (trigeminal)
B. Cranial nerve VII (facial)
C. Cranial nerve IX (glossopharyngeal)
D. Cranial nerve XII (hypoglossal)
Rationale: Cranial nerve VII (facial nerve) provides motor innervation to the muscles of facial
expression, including those used for smiling, frowning, raising eyebrows, and puffing cheeks. CN V
provides sensory innervation to the face and motor to muscles of mastication. CN IX provides taste to
the posterior tongue and sensory to the pharynx. CN XII controls tongue movement.
Q3. A 72-year-old patient reports new-onset unilateral headache and jaw claudication. On
palpation of the temporal arteries, the nurse notes tenderness and diminished pulses.
Which condition must be urgently considered?
A. Tension headache
B. Giant cell (temporal) arteritis
C. Migraine with aura D. Cluster headache
Rationale: Giant cell arteritis (temporal arteritis) is a medical emergency presenting with unilateral
headache, temporal artery tenderness, and jaw claudication in patients over 50. It can cause
irreversible blindness if untreated due to ophthalmic artery involvement. Urgent ESR/CRP testing and
corticosteroid initiation are required. Tension and migraine headaches do not present with temporal
artery tenderness. Cluster headache causes severe unilateral periorbital pain without artery changes.
Q4. During temporomandibular joint (TMJ) assessment, the nurse palpates the joint while
the patient opens and closes the mouth. A palpable click is noted on opening without pain
or limited range of motion. This finding is best interpreted as:
A. A normal variant requiring no further evaluation
, B. Evidence of TMJ dislocation requiring imaging
C. A sign of rheumatoid arthritis
D. An indication for immediate surgical referral
Rationale: A painless, isolated click during jaw opening is a common benign finding in TMJ assessment
and is considered a normal variant when unaccompanied by pain, limited range of motion, or crepitus.
It results from the articular disc briefly displacing and reducing. TMJ dislocation presents with inability
to close the mouth. Rheumatoid arthritis causes crepitus and pain. Surgical referral is reserved for
refractory cases with significant dysfunction.
Q5. When evaluating sinus tenderness, the nurse should palpate the frontal sinuses by
pressing upward and the maxillary sinuses by pressing:
A. Medially along the nasal bridge
B. Upward under the zygomatic arch
C. Downward on the bony ridge above the eyebrows
D. Laterally on the mastoid process
Rationale: The maxillary sinuses are palpated by pressing upward under the zygomatic arch
(cheekbone area) to assess for tenderness. The frontal sinuses are palpated by pressing upward on the
supraorbital ridge. The nasal bridge corresponds to the nasal bones, not sinuses. The bony ridge above
the eyebrows is the frontal sinus site. The mastoid process is posterior to the ear and unrelated to sinus
palpation.
Q6. The nurse observes that a patient's face appears mask-like with decreased facial
expression and slow, shuffling movements. This presentation is most consistent with
which neurological condition affecting facial expression?
A. Bell's palsy
B. Parkinson's disease
C. Myasthenia gravis D. Stroke
Rationale: A mask-like face (hypomimia) with bradykinesia and shuffling gait is characteristic of
Parkinson's disease, which causes rigidity of facial muscles. Bell's palsy presents with acute unilateral
facial weakness, not bilateral mask-like expression. Myasthenia gravis causes fluctuating fatigable
weakness, often with ptosis. Stroke typically presents with acute unilateral weakness, not a progressive
bilateral mask-like appearance.
Q7. A patient presents with facial asymmetry that includes drooping of the right corner of
the mouth and inability to raise the right eyebrow. This pattern is most consistent with
which type of facial nerve lesion?
A. Central (upper motor neuron) lesion
B. Peripheral (lower motor neuron) lesion of CN VII
C. Trigeminal nerve lesion
D. Recurrent laryngeal nerve lesion
Rationale: A peripheral CN VII lesion affects both the upper and lower face on the ipsilateral side,
including forehead involvement (inability to raise eyebrow). A central lesion spares the forehead due to
bilateral upper motor neuron innervation of the upper face. CN V provides sensory supply, not motor to
facial muscles. The recurrent laryngeal nerve innervates the larynx, not facial muscles.
Q8. Which assessment technique correctly evaluates the range of motion of the
temporomandibular joint?
A. Asking the patient to protrude and retract the tongue while observing jaw movement
B. Placing fingertips over the TMJ and asking the patient to open and close the mouth
slowly
C. Pressing firmly on the mastoid process while the patient swallows
D. Inspecting the external auditory canal with an otoscope during jaw clenching
