Section 1: Case History & Presenting Complaints
1. What is the primary presenting complaint for Colt in this
Simucase case study?
A) Aphonia secondary to acute laryngeal inflammation
B) Dysphonia characterized by chronic hoarseness and vocal fatigue
C) Hypernasality with intermittent pitch breaks
D) Functional mutism with associated vocal tremor
Correct Answer: B) Dysphonia characterized by chronic hoarseness
and vocal fatigue.
Rationale: Colt presents with a voice disorder (dysphonia) that has
developed over time due to vocal misuse/abuse patterns. Hoarseness is
the hallmark symptom of vocal fold nodules and reflects the mass effect
of bilateral lesions interfering with vocal fold vibration .
2. During the initial clinical intake interview, the caregiver reports
that Colt's voice sounds consistently breathy, rough, and strained,
particularly after a full day at school. How should the Speech-
Language Pathologist (SLP) document this specific combination of
auditory-perceptual vocal qualities?
A) Hypernasality with intermittent pitch breaks
B) Dysphonia characterized by hoarseness and vocal strain
C) Aphonia secondary to acute laryngeal inflammation
D) Functional mutism with associated vocal tremor
Correct Answer: B) Dysphonia characterized by hoarseness and vocal
strain.
,Rationale: Dysphonia is a general term for any impairment of voice
production or alteration in vocal quality. The combination of breathiness,
roughness, and strain is clinically referred to as hoarseness, which is a
classic perceptual hallmark of mechanical changes to the vocal folds,
such as bilateral vocal nodules .
3. The SLP reviews Colt's background history and notes a pattern of
frequent throat clearing, yelling on the playground, and mimicking
loud engine sounds during play. Which clinical term best classifies
these specific behaviors?
A) Vocal load adjustments
B) Laryngeal structural adaptations
C) Vocal hyperfunction and phonotrauma
D) Compensatory supraglottic constriction
Correct Answer: C) Vocal hyperfunction and phonotrauma.
Rationale: Phonotrauma refers to vocal behaviors (intentional or
unintentional) that can cause mechanical tissue strain, trauma, or
structural changes to the vocal folds. Chronic yelling, throat clearing, and
loud vocal play are primary phonotraumatic behaviors that lead to the
development of vocal nodules in children .
4. What is the most likely etiology of Colt's vocal nodules?
A) Viral infection of the vocal folds
B) Prolonged vocal abuse or misuse (phonotrauma)
C) Congenital laryngeal web
D) Sudden traumatic injury to the larynx
Correct Answer: B) Prolonged vocal abuse or misuse (phonotrauma).
Rationale: Vocal nodules are the most common benign laryngeal lesions
and are directly associated with voice strain or abuse—yelling, excessive
talking, singing without proper technique, or occupational voice
demands. They develop at the junction of the anterior one-third and
posterior two-thirds of the vocal folds, where collision forces are
greatest .
,5. What demographic factors are most associated with vocal
nodules?
A) Elderly males
B) Children and adult females
C) Adolescents of both genders
D) Elderly females
Correct Answer: B) Children and adult females.
Rationale: Vocal nodules are most commonly seen in children and adult
females, though they occur across all populations with vocally
demanding lifestyles. The higher prevalence in females is attributed to
anatomical differences and hormonal influences on laryngeal tissue .
Section 2: Medical & Laryngeal Examination
6. Before commencing structural voice therapy or an in-depth
behavioral voice assessment, which medical clearance is legally and
ethically mandated for an SLP to obtain?
A) An audiological evaluation report
B) A pediatric laryngeal examination by an Otolaryngologist (ENT)
C) A complete neurological screening profile
D) A swallow evaluation from a pediatric gastroenterologist
Correct Answer: B) A pediatric laryngeal examination by an
Otolaryngologist (ENT).
Rationale: According to the ASHA Scope of Practice, an SLP must ensure
that a client has undergone a medical laryngeal examination (typically via
endoscopy or stroboscopy by an ENT) prior to initiating voice therapy.
This is critical to rule out organic pathologies, malignancies, or lesions
that require medical or surgical intervention rather than behavioral
therapy .
7. What laryngeal findings would be expected on rigid stroboscopy
in Colt's case?
A) Unilateral vocal fold paralysis
B) Bilateral, symmetrical lesions at the mid-membranous vocal folds with
hourglass glottic closure and relatively preserved mucosal wave
, C) Unilateral hemorrhagic polyp
D) Bilateral severe edema of the false vocal folds
Correct Answer: B) Bilateral, symmetrical lesions at the mid-
membranous vocal folds with hourglass glottic closure and
relatively preserved mucosal wave.
Rationale: Rigid stroboscopy provides the clearest view of vocal fold
vibration and lesion characteristics. The classic findings for nodules
include bilateral lesions, hourglass glottic configuration, and assessment
of the mucosal wave . This location represents the point of maximum
shearing and collision forces during phonation .
8. What is the "hourglass appearance" on videostroboscopy?
A) A glottic closure pattern where the anterior and posterior portions
approximate but the middle portion has a gap due to nodule
interposition.
B) A complete lack of glottic closure from anterior to posterior.
C) A hyperfunctional closure where the arytenoids are compressed.
D) An hourglass-shaped epiglottis.
Correct Answer: A) A glottic closure pattern where the anterior and
posterior portions approximate but the middle portion has a gap
due to nodule interposition.
Rationale: The bilateral nodules prevent complete glottic closure at the
mid-membranous portion, creating an hourglass-shaped gap during
phonation .
9. What is the characteristic location of vocal nodules on the vocal
folds?
A) The posterior cartilaginous portion
B) At the junction of the anterior one-third and posterior two-thirds of
the membranous vocal folds.
C) The anterior commissure
D) The arytenoid cartilages
Correct Answer: B) At the junction of the anterior one-third and
posterior two-thirds of the membranous vocal folds.
