Q: A newborn is unable to coordinate sucking, swallowing, and breathing, resulting in tube feeding. Which formula best describes the risk of aspiration in this scenario?

$$\text{Aspiration Risk} = \frac{\text{Uncoordinated Suck/Swallow/Breathe}}{\text{Total Feeding Attempts}}$$

Q: In the context of swallowing disorders, which formula best represents the relationship between muscle load, resistance, and intensity in exercise-based therapy?

$$\text{Swallowing Improvement} = \text{Task Specificity} \times \text{Muscle Load} \times \text{Resistance} \times \text{Intensity}$$

Question 1

Which phase of swallowing is primarily responsible for preventing the bolus from entering the nasal cavity, and what anatomical structure is involved?

Accepted Answer

Pharyngeal phase; the velum moves up to meet the rear wall of the pharynx.

Question 2

A patient with dysphagia after a stroke exhibits slow tongue movements, reduced hyolaryngeal elevation, and silent aspiration of thin liquids. Which compensatory strategy is most likely to reduce aspiration risk for this patient?

Accepted Answer

Chin tuck posture to prevent food and liquid from entering the airway.

Question 3

Which of the following is a common etiology of pediatric dysphagia that results in an inability to create negative intraoral pressure, leading to nasopharyngeal regurgitation?

Accepted Answer

Craniofacial anomalies such as cleft lip and palate

Question 4

During the clinical swallow evaluation (CSE), which component is essential for determining whether a patient is safe to assess for feeding and swallowing abilities?

Accepted Answer

Cognitive-communication functioning

Question 5

A patient with Parkinson disease is experiencing reduced chewing speed, delayed initiation of swallow, and frequent swallows to clear the pharynx. Which evidence-based intervention is most likely to improve swallowing function?

Accepted Answer

Use of thickened liquids and chin tuck technique

Question 6

Which instrumental assessment is best suited for repeated swallow studies in patients with head and neck cancer to minimize radiation exposure?

Accepted Answer

Fiberoptic endoscopic evaluation of swallowing (FEES)

Question 7

A newborn is unable to coordinate sucking, swallowing, and breathing, resulting in tube feeding. Which formula best describes the risk of aspiration in this scenario?

Accepted Answer

$$	ext{Aspiration Risk} = \frac{	ext{Uncoordinated Suck/Swallow/Breathe}}{	ext{Total Feeding Attempts}}$$

Question 8

Which of the following is NOT a goal of compensatory strategies for feeding and swallowing disorders?

Accepted Answer

Accelerate recovery of swallowing function by changing swallowing physiology

Question 9

A patient with severe dysphagia requires long-term nutrition and hydration. Which nonoral feeding method involves a surgically created hole from the abdomen to the stomach?

Accepted Answer

Percutaneous endoscopic gastrostomy (PEG or G-tube)

Question 10

Which swallowing-specific exercise is designed to improve retraction of the base of the tongue toward the posterior pharyngeal wall, thereby helping propel the bolus into the oropharynx?

Accepted Answer

Effortful swallow exercise

Question 11

In the context of swallowing disorders, which formula best represents the relationship between muscle load, resistance, and intensity in exercise-based therapy?

Accepted Answer

$$	ext{Swallowing Improvement} = 	ext{Task Specificity} 	imes 	ext{Muscle Load} 	imes 	ext{Resistance} 	imes 	ext{Intensity}$$

Question 12

Which of the following is a plausible reason for recommending thickened liquids to a patient with dysphagia?

Accepted Answer

Thickened liquids reduce the risk of aspiration by slowing the flow of liquid.

Question 13

A patient with head and neck cancer post-surgery is experiencing decreased salivation and dry mouth. Which compensatory strategy is most likely to help maintain oral intake?

Accepted Answer

Maintaining oral intake during radiation treatment

Question 14

Which formula best represents the calculation for the percentage of aspiration during swallow trials?

Accepted Answer

$$	ext{Aspiration Percentage} = \frac{	ext{Volume Aspirated}}{	ext{Total Volume Swallowed}} 	imes 100$$

Question 15

Which evidence-based practice is most effective for adults with severe reflux, including those that are tube-fed, to prevent aspiration of stomach acids?

Accepted Answer

Maintaining an upright posture during and after eating

Question 16

Which instrumental technique provides real-time information about muscle activation during swallowing and is used as a biofeedback tool?

Accepted Answer

Surface electromyography (sEMG)

Question 17

A patient with dementia is forgetting to eat and has prolonged oral transport. Which intervention is most likely to improve feeding and swallowing function?

Accepted Answer

Ensuring eating occurs in a familiar environment free from distractions

Question 18

Which formula best describes the calculation for swallowing efficiency during a swallow trial?

Accepted Answer

$$	ext{Swallowing Efficiency} = \frac{	ext{Number of Successful Swallows}}{	ext{Total Number of Trials}} 	imes 100$$
