Instrumental swallow items on the Praxis 5331 test whether you can choose between MBSS (VFSS) and FEES, interpret common findings, and know each procedure's limits. Expect scenarios about aspiration versus penetration, silent aspiration, and when each test is contraindicated.
Try answering before revealing the rationale — mark misses to retry later.
Q1.A patient's clinical swallow exam suggests residue in the pharynx and possible aspiration. There are concerns about repeated radiation exposure. The best instrumental choice is:
Correct: B. FEES avoids radiation and directly visualizes pharyngeal residue and airway invasion. It is a strong choice when radiation is a concern.
Q2.A score of 8 on the Penetration-Aspiration Scale indicates:
Correct: B. PAS 8 = material below the vocal folds with no attempt to eject — silent aspiration. This is the highest-risk finding.
Q3.MBSS is preferred over FEES when the SLP needs to evaluate:
Correct: B. MBSS visualizes all swallow phases including oral prep and the upper esophageal segment. FEES cannot show what happens during the white-out phase or below the pharynx.

Can SLPs perform FEES independently?
Yes, with proper training and institutional privileges. ASHA has practice guidelines for FEES competencies.
Which procedure detects silent aspiration better?
Both can detect silent aspiration. MBSS shows the whole swallow; FEES gives direct laryngeal view without radiation.
Do instrumental studies replace the clinical swallow exam?
No — they answer specific questions raised by the clinical exam and guide diet and strategy decisions.
