NPTE-PT NPTE-PT Test Therapeutic Modalities Application Questions and Answers 2

Question 1

A physical therapist is treating a patient with acute lateral epicondylitis. Which therapeutic modality is MOST appropriate for pain management during the inflammatory phase?

Accepted Answer

Phonophoresis with hydrocortisone

Answer

Phonophoresis with hydrocortisone delivers anti-inflammatory medication transdermally to the inflamed tendon using ultrasound as the driving force.

Question 2

A patient with a 3-week-old grade II MCL sprain is referred for physical therapy. What is the PRIMARY reason for selecting pulsed ultrasound over continuous ultrasound at this stage?

Accepted Answer

Pulsed ultrasound minimizes thermal buildup in subacute tissue

Answer

Pulsed ultrasound is preferred in the subacute phase because it provides nonthermal mechanical effects while minimizing heat accumulation in healing tissue.

Question 3

When applying iontophoresis with dexamethasone to treat plantar fasciitis, which electrode placement is correct?

Accepted Answer

Dexamethasone under the negative electrode, dispersive pad on the dorsum

Answer

Dexamethasone is negatively charged and must be placed under the negative (cathode) electrode so that like charges repel the medication into the tissue.

Question 4

A physical therapist selects shortwave diathermy for a patient with chronic low back pain and deep muscle guarding. Which of the following is an ABSOLUTE contraindication?

Accepted Answer

Metal jewelry that cannot be removed from the treatment area

Answer

Metal in the treatment field concentrates electromagnetic energy and can cause deep tissue burns, making it an absolute contraindication for shortwave diathermy.

Question 5

A patient recovering from a total knee arthroplasty is 6 weeks post-operative with persistent quadriceps inhibition. Which neuromuscular electrical stimulation (NMES) parameter setting is MOST appropriate to facilitate quadriceps re-education?

Accepted Answer

Frequency 35-50 Hz, ramp up 2-3 sec, on:off ratio 1:5

Answer

A frequency of 35-50 Hz produces a tetanic contraction suitable for strengthening, and the 1:5 on:off ratio prevents rapid fatigue in a weakened quadriceps.
