We’ve asked experts in the field to challenge us with a little dysphagia pop quiz. Test your knowledge! Share with students and fellow clinicians! Put your answers in comments below and we’ll post the answers soon. Follow #dysphagiapopquiz on Twitter.

Our first set of questions come courtesy of Donna Edwards, MA CCC-SLP, BCS-S. Donna is a senior clinician at Dayton Children’s Hospital.

Pediatric Anatomy

2. Infant head position with hyperextension or hyperflexion of the pliable trachea results in:

a. Increased airway opening
b. Complete or partial airway occlusion
c. Improved airflow
d. Efficient swallow response

3. The least commonly occurring airway protection event in premature and healthy infants is:
