Swallowing and Feeding Disorders Flashcards

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

Answer: Oral transport phase

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

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

Answer: Laryngeal vestibule above the vocal folds

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

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

Answer: Modified barium swallow study (MBSS)

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

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

Answer: Cough or throat clear

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

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

Answer: Depth and response to airway invasion

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

Which compensatory swallowing strategy involves turning the head toward the weaker side to redirect the bolus?

Answer: Head turn

Head rotation toward the damaged side closes off that pyriform sinus, directing the bolus to the stronger side for safer passage.
