CCC Swallowing and Feeding Disorders 1

Question 1

Which phase of swallowing involves the bolus being moved from the anterior to the posterior oral cavity by the tongue?

Accepted Answer

Oral transport phase

Answer

The oral transport (propulsion) phase involves the tongue propelling the bolus posteriorly toward the pharynx.

Question 2

Laryngeal penetration during swallowing is defined as bolus material entering which structure without passing below the vocal folds?

Accepted Answer

Laryngeal vestibule above the vocal folds

Answer

Penetration occurs when material enters the laryngeal vestibule (above the vocal folds) but does not pass below them into the trachea.

Question 3

Which instrumental assessment uses fluoroscopy to evaluate all phases of swallowing in real time?

Accepted Answer

Modified barium swallow study (MBSS)

Answer

The Modified Barium Swallow Study uses dynamic fluoroscopy with barium-coated boluses to visualize swallowing physiology across all phases.

Question 4

Silent aspiration is defined as aspiration that occurs without which response?

Accepted Answer

Cough or throat clear

Answer

Silent aspiration occurs when material enters the airway below the vocal folds without triggering a cough or throat-clearing response.

Question 5

The Penetration-Aspiration Scale (PAS) is an 8-point scale used during instrumental swallowing evaluation to rate:

Accepted Answer

Depth and response to airway invasion

Answer

The PAS rates the depth at which material enters the airway and the patient's response (cough, no response) on an 8-point scale.
