Which cranial nerve is responsible for the gag reflex (afferent limb)?
Answer: Cranial nerve IX
CN IX (glossopharyngeal) carries the afferent signal from the posterior pharynx for the gag reflex, while CN X carries the efferent motor response.
A PT measures a patient's shoulder ROM at 160° of flexion. According to the APTA, the normal value for shoulder flexion is:
Answer: 180°
Normal shoulder flexion is 180° according to standard physical therapy reference values.
Which type of muscle contraction produces the greatest force output?
Answer: Eccentric
Eccentric contractions produce the greatest tension because cross-bridge cycling is combined with external stretching forces.
A patient reports that pain decreases with walking and worsens with prolonged sitting. This pattern is MOST consistent with:
Answer: Discogenic low back pain
Discogenic pain typically worsens with flexion-loaded postures like prolonged sitting and improves with extension activities such as walking.
When applying TENS for pain modulation using the gate control mechanism, which parameters are used?
Answer: High frequency (80–150 Hz), low intensity (sensory level)
Conventional (high-frequency, low-intensity) TENS activates large-diameter Aβ fibers to close the pain gate at the dorsal horn.
Which balance component is primarily tested by the Romberg test?
Answer: Vestibular and proprioceptive integration
The Romberg test assesses somatosensory and vestibular contributions to balance by removing the visual input (eyes closed).
A patient with COPD is completing pulmonary rehabilitation. Target SpO2 during exercise should be maintained at a minimum of:
Answer: 92%
Exercise should be modified or supplemental oxygen provided if SpO2 drops below 88–90%; 88% is the clinical threshold, but 92% is the safe exercise target.
