Dysphagia and Swallowing Disorders Across the Lifespan
This domain tests swallowing anatomy, bedside and instrumental assessment, diet modification, and safety planning in adults and children.
Core rules
- Swallowing has oral preparatory, oral, pharyngeal, and esophageal phases. Dysphagia may cause aspiration, malnutrition, dehydration, or pneumonia.
- Adults: common causes include stroke, Parkinson disease, dementia, and head/neck cancer. Children: prematurity, cerebral palsy, cleft palate, and cardiopulmonary disease are common.
- Clinical examination informs but does not confirm aspiration. Videofluoroscopic swallow study (VFSS) and fiberoptic endoscopic evaluation of swallowing (FEES) show physiology and residue. Use IDDSI levels consistently for liquids and foods.
- Modify texture only with rationale, monitor hydration and nutrition, and involve dietetics and medicine.
Worked example
An acute stroke patient coughs on thin liquids and shows a delayed swallow trigger on bedside screening. The patient is alert and can participate. Do not empirically restrict all fluids. Request instrumental assessment, trial IDDSI level 1 or 2 liquid with confirmed safety, and document posture, cueing, and residue. Reassess after neurologic recovery rather than leaving an indefinite thick-liquid order.
Traps that cost marks
- Diagnosing aspiration from a cough alone without instrumental confirmation.
- Using thickened liquids indefinitely without review.
- Ignoring oral hygiene, medication effects, and nutrition.
- Applying adult textures to infants without pediatric rationale.
