SIMUCASE COLT VOICE ASSESSMENT
QUESTIONS AND ANSWERS BANK - SLP
DYSPHONIA & VOCAL NODULES
EVALUATION GUIDE
This comprehensive question multiple-choice practice bank delivers
detailed rationales and verified answers explicitly tailored to the
Simucase "Colt" pediatric voice disorder case study. It covers the full
clinical spectrum of speech-language pathology evaluation and
behavioral management for a 12-year-old male presenting with
dysphonia and bilateral vocal nodules. Designed directly for
graduate-level speech pathology students, this high-yield digital
study guide serves as an ideal resource to master laryngeal
mechanics, acoustic diagnostics, and evidence-based voice therapy
protocols.
Question 1
A 12-year-old male, Colt, presents with a 6-month history of progressive
hoarseness, a breathy vocal quality, and frequent throat clearing. He is
highly active in competitive youth soccer and choir. What is the most likely
structural pathology given this clinical presentation?
A) Vocal fold paralysis
B) Bilateral vocal nodules
C) Laryngeal papilloma
D) Contact ulcers
Answer: B
**Rationale: Bilateral vocal nodules are the most common structural
,voice pathology in school-aged children, typically caused by chronic
vocal abuse or phonotrauma (e.g., yelling at soccer matches,
improper singing technique). This manifests as hoarseness,
breathiness, and compensatory throat clearing.
Question 2
During the initial case history interview for Colt, which of the following
questions is most critical for identifying specific phonotraumatic behaviors?
A) "What is your favorite subject in middle school?"
B) "How many glasses of water do you drink during soccer practice?"
C) "Can you describe how you cheer or talk to teammates during soccer
games?"
D) "Do you have a family history of late-onset hearing loss?"
Answer: C
**Rationale: Identifying specific situational vocal abuses (like yelling
across an athletic field) targets the root behavioral cause of
phonotrauma, which is crucial for developing an effective behavioral
management plan.
Question 3
Colt’s acoustic assessment reveals an increased jitter percentage. What
does an elevated jitter value primarily represent in a voice evaluation?
A) Rapid variations in vocal intensity
B) Cycle-to-cycle variability in fundamental frequency
C) The ratio of harmonic energy to noise energy
D) Maximum phonation time limitations
Answer: B
**Rationale: Jitter measures the cycle-to-cycle frequency perturbations
of vocal fold vibration. Structural lesions like nodules disrupt mass
and tension symmetry, causing higher frequency variability (jitter).
Question 4
An aerodynamic assessment of Colt’s voice indicates a significantly
elevated mean airflow rate during phonation. What does this finding
,objectively indicate regarding his laryngeal function?
A) Hyperfunctional medial compression
B) Incomplete glottal closure during the closed phase
C) Excessive subglottic pressure buildup
D) Superb respiratory support and vital capacity
Answer: B
**Rationale: Vocal fold nodules prevent complete mid-membranous
adduction, creating an hourglass glottal gap. This gap allows
excessive air to escape continuously during phonation, elevating the
mean airflow rate.
Question 5
Which perceptual voice rating scale is most widely utilized by SLPs to
characterize Colt's overall severity, roughness, breathiness, asthenia, and
strain?
A) The VHI-10 Scale
B) The CAPE-V Protocol
C) The Boone Voice Program
D) The GRBAS Scale
Answer: D
**Rationale: The GRBAS scale (Grade, Roughness, Breathiness,
Asthenia, Strain) is a standardized, internationally recognized
perceptual rating tool that provides a quick profile of a patient’s
dysphonia severity.
Question 6
If an SLP utilizes the CAPE-V instead of the GRBAS to rate Colt's voice,
what specific procedural advantage does the CAPE-V offer?
A) It uses a visual analog scale rather than a 4-point ordinal scale
B) It requires an invasive laryngeal probe
C) It measures vital capacity directly using a spirometer
D) It relies entirely on automated computer algorithms
Answer: A
**Rationale: The CAPE-V utilizes a 100mm visual analog scale to mark
, severity, providing greater sensitivity to subtle perceptual changes
over the course of voice therapy compared to 4-point ordinal rating
scales.
Question 7
During the oral peripheral examination, Colt demonstrates normal structural
symmetry, normal range of motion, and adequate lingual/labial strength.
What does this help rule out?
A) Chronic vocal hyperfunction
B) Structural vocal fold lesions
C) Co-occurring neurogenic dysarthria
D) Inadequate vocal hygiene habits
Answer: C
**Rationale: A normal oral peripheral exam ensures that speech motor
cranial nerves are intact, ruling out primary neurogenic motor speech
disorders (dysarthria) as the primary cause of his vocal profile.
Question 8
Colt's maximum phonation time (MPT) is notably reduced (under 10
seconds). Which of the following factors best explains this reduction in a
patient with bilateral nodules?
A) Severe diaphragmatic weakness
B) Increased glottal resistance
C) Transglottic air leakage due to incomplete glottal closure
D) A restrictive lung disease profile
Answer: C
**Rationale: Because bilateral nodules prevent the vocal folds from
sealing completely, air leaks rapidly out of the lungs during sustained
phonation, causing the patient to exhaust their air supply prematurely
and shortening MPT.
Question 9
When computing the s/z ratio for Colt, the SLP obtains an s/z ratio of 1.65.
How should this clinical finding be interpreted?
