Question 1

Hot packs transfer heat to the body primarily through which mechanism?

Accepted Answer

Conduction

Answer

Hot packs transfer heat through conduction, which is the direct transfer of heat from one object to another through physical contact.

Question 2

What is the recommended temperature range for a therapeutic warm whirlpool used for general extremity treatment?

Accepted Answer

102°F-110°F (38.9°C-43.3°C)

Answer

The recommended temperature for a therapeutic warm whirlpool for extremity treatment is 102°F-110°F (38.9°C-43.3°C).

Question 3

Interferential current (IFC) therapy typically uses which carrier frequency?

Accepted Answer

4,000 Hz

Answer

Interferential current therapy uses a carrier frequency of approximately 4,000 Hz (4 kHz), with two slightly different frequencies creating a therapeutic beat frequency in the target tissue.

Question 4

In pulsed ultrasound with a 20% duty cycle, what does this signify?

Accepted Answer

The ultrasound is on for 20% of the total treatment time

Answer

A 20% duty cycle means the ultrasound is active for 20% of the total pulse period, reducing the average heating effect while maintaining mechanical effects.

Question 5

Phonophoresis combines therapeutic ultrasound with which additional treatment?

Accepted Answer

Topical medication delivery

Answer

Phonophoresis uses ultrasound energy to drive topical medications such as corticosteroids or anti-inflammatory agents transdermally into underlying tissues.
