Question 1 · Neurology, Clinical
Which description fits penetration in a swallowing assessment?
- A. Aspiration with overt signs, such as coughing
- B. Food, fluid, or saliva at or below the level of the vocal fold
- C. Aspiration without coughing or other overt signs
- D. Food, fluid, or saliva entering the laryngeal inlet but staying above the vocal folds
- E. Difficulty swallowing fluid, food, or saliva
Show the answer and explanation
Answer: D. Food, fluid, or saliva entering the laryngeal inlet but staying above the vocal folds
Penetration is food, fluid, or saliva that enters the laryngeal inlet but stays above the vocal folds. Aspiration is at or below the level of the vocal fold, and it is audible or overt when there are signs such as coughing and silent when there are none.
Why the other options are wrong
- A. Aspiration with overt signs, such as coughing: This describes audible or overt aspiration.
- B. Food, fluid, or saliva at or below the level of the vocal fold: This describes aspiration.
- C. Aspiration without coughing or other overt signs: This describes silent aspiration.
- E. Difficulty swallowing fluid, food, or saliva: This describes dysphagia.
Key point: Penetration stays above the vocal folds, whereas aspiration is at or below the level of the vocal fold.
