Q

What is the difference between a swallowing disorder, a feeding disorder, and an eating disorder?

A

swallowing disorder: impairment in any of the structures that allow for swallowing, from the oral cavity through the esophagus; feeding disorder: an impairment in the process of food transport outside of the alimentary system; eating disorder: mental health disorder that does not, necessarily, involve impaired anatomy

Q

Why would a patient receive subacute care?

A

step down from acute; these patients are usually not ready for rehabilitation services; for example, someone on a ventilator that needs some level of acute care and is not ready to be released

Q

The cricopharyngeus is part of which pharyngeal constrictor muscle?

A

the inferior pharyngeal constrictor

20
Q

Which cranial nerve provides general sensory to the anterior 2/3 of the tongue?

A

CN V (trigeminal)

21
Q

Which muscle is in charge of vocal fold abduction?

A

posterior cricoarytenoid muscle

22
Q

Which muscle is credited with initiating hyolaryngeal movement?

A

geniohyoid muscle

23
Q

Which CN is responsible for the pharyngeal stripping wave?

A

pharyngeal plexus

24
Q

A patient demonstrating oral escape of liquids most likely has a damage to which CN?

A

CN VII (facial)

25
Q

A patient experiencing difficulty retracting and elevating their tongue, might have an impairment in which muscle?

A

styloglossus

26
Q

A patient struggling to manipulate a bolus might have an impairment to which CN?

A

CN XII (hypoglossal)

27
Q

Which nerve is responsible for VF approximation during a swallow?

A

recurrent laryngeal nerve

28
Q

Name some anatomical differences between infant and adult patients

A

oral cavity, jaw, stomach, and esophagus are smaller; tongue is relatively larger; the uvula and the epiglottis are in contact already because the epiglottis is higher in infants and starts to descend by the time they are 2 years old

29
Q

How can infants compensate for having a larger tongue to oral cavity size ratio than their adult counterparts?

A

they can breathe through their noses while they eat

30
Q

What is the best suck : swallow : breath ratio for infants?

A

1:1:1

31
Q

What is the rooting instinct in infants?

A

when infants experience tactile stimulation to the side of their face or near their mouth, they instinctively turn their head towards it and open their mouth

32
Q

What is the difference between nutritive and nonnutritive suckling?

A

nutritive suckling is for feeding and nonnutritive suckling is for soothing

33
Q

How long is a normal human gestation period?

A

40 weeks

34
Q

What is a tongue tie and how does it interfere with infant feeding?

A

a restricted frenulum can cause latching challenges

35
Q

What is a feeding side effect of a cleft lip/palate?

A

an inability to create a good seal and suck

36
Q

How do neurological conditions like CP or DS affect infant feeding?

A

can result in low muscle tone

37
Q

How do cardiac problems impact infant feeding?

A

reduced endurance

38
Q

What is the phenomenon of normal age-related changes in the aerodigestive tract called?

A

presbyphagia

39
Q

How does frailty put an older adult at risk for dysphagia?

A

change in muscle strength, cognitive decline, etc.

40
Q

What is it called when an older adult has reduced lean skeletal muscles mass with a marked loss of strength and speed of movement?

A

sarcopenia

41
Q

What are some age-related physical changes in the oral phase?

A

dental changes; more fat and atrophy in lingual muscles; decline in perception of spatial tactile recognition in the lips and tongue, and of viscosity in the oral cavity; decline in taste perception; longer oral transit time; increase in oral residue (might be functional, still)

42
Q

What are some age-related changes in the pharyngeal phase?

A

reduced amplitude of hyoid elevation and excursion, increased pharyngeal transit duration, less powerful pharyngeal constriction, delay in swallow onset, atrophied thyroarytenoid muscles

43
Q

What are some age-related changes that affect the esophageal phase?

A

weaker UES closure, lower amplitudes of peristaltic movement, esophageal dysmobility

44
Q

What percentage of individuals over 65 experience presbyphagia?

A

40%

45
Q

What are some clinical issues that can arise from dysphagia?

A

malnutrition, dehydration, morbidity, mortality, hospitalization, respiratory complications, social isolation

46
Q

Where does the swallow trigger?

A

research says that about 80% of swallows do not trigger until after the head of the bolus pass the ramus of the mandible; many swallows trigger after the head of the bolus is at the level of the valleculae or pyriform sinuses
