Question 1

A patient with chronic low back pain is being treated with transcutaneous electrical nerve stimulation (TENS). Which parameter adjustment would MOST likely increase the depth of current penetration?

Accepted Answer

Increase the pulse duration

Answer

Increasing pulse duration allows more charge to be delivered per pulse, which increases the depth of current penetration into tissue.

Question 2

When applying cervical traction using a mechanical unit, what is the recommended treatment angle to target the lower cervical segments (C5-C7)?

Accepted Answer

25-30 degrees of flexion

Answer

Approximately 25-30 degrees of cervical flexion is recommended to effectively target the lower cervical segments during mechanical traction.

Question 3

A physical therapist is using phonophoresis to deliver dexamethasone to a patient's inflamed supraspinatus tendon. What ultrasound parameter is MOST appropriate?

Accepted Answer

3 MHz, pulsed 20%, 0.5 W/cm2

Answer

For phonophoresis targeting a superficial structure, 3 MHz pulsed at low intensity is preferred to drive medication without excessive thermal effects.

Question 4

Which assistive device gait pattern requires the HIGHEST energy expenditure?

Accepted Answer

Swing-through pattern with bilateral crutches

Answer

The swing-through gait pattern requires the highest energy expenditure because the patient must lift and propel the entire body past the crutches with each stride.

Question 5

A patient with a Stage III pressure injury on the sacrum has significant wound exudate. Which therapeutic modality is MOST appropriate to promote wound healing?

Accepted Answer

Pulsed lavage with suction

Answer

Pulsed lavage with suction provides effective wound debridement and exudate management while promoting granulation tissue formation in pressure injuries.
