DPT 570 EXAM 1- PHYSICAL AGENTS AND IMPAIRMENTS UPDATED EXAM WITH
MOST TESTED QUESTIONS AND ANSWERS | GRADED A+ | ASSURED SUCCESS
WITH DETAILED RATIONALES
1. Physical agents are best defined as which of the following?
A. Exercises designed to improve strength and endurance
B. Energy and materials applied to assist rehabilitation
C. Manual therapy techniques only
D. Pharmacologic agents used in therapy
Rationale: Physical agents include externally applied energies or materials used to facilitate
healing, pain control, and tissue recovery—not exercise or medications.
2. Which list correctly identifies the three major categories of physical agents?
A. Chemical, biological, mechanical
B. Electrical, thermal, acoustic
C. Thermal, mechanical, electromagnetic
D. Passive, active, functional
Rationale: Physical agents are classified by the type of energy applied: thermal, mechanical, or
electromagnetic.
3. Which is an example of a superficial heating agent?
A. Ultrasound
B. Diathermy
C. Hot packs
D. Laser
Rationale: Superficial heating agents heat tissues close to the skin surface; ultrasound and
diathermy are deep-heating modalities.
4. Which modality is classified as a mechanical agent?
A. Electrical stimulation
B. Traction
,ESTUDYR
C. Infrared light
D. Shortwave diathermy
Rationale: Mechanical agents apply physical forces such as pressure or movement (e.g.,
traction, massage).
5. Which modality is an electromagnetic agent?
A. Massage
B. Ice
C. Electrical current
D. Hydrotherapy
Rationale: Electrical currents and electromagnetic fields fall under electromagnetic physical
agents.
6. Within the ICF model, physical agents primarily address which domain?
A. Activity limitations
B. Participation restrictions
C. Environmental factors
D. Body function and structure
Rationale: Modalities target impairments in tissues and physiological processes rather than
participation-level outcomes.
7. Which impairment category is MOST appropriate for treatment using physical agents?
A. Social participation deficits
B. Cognitive dysfunction only
C. Neuromusculoskeletal impairments
D. Financial barriers
Rationale: Physical agents are commonly used to address neuromusculoskeletal, integumentary,
and sensory impairments.
, ESTUDYR
8. Can physical agents be used as the sole intervention in rehabilitation?
A. Yes, if pain relief is achieved
B. Yes, in acute conditions only
C. No, they must be combined with active interventions
D. Only in elderly patients
Rationale: Modalities are adjuncts and must support active rehabilitation strategies.
9. According to the Choosing Wisely campaign, which intervention should be avoided for
long-term musculoskeletal outcomes?
A. Strength training
B. Manual therapy
C. Heat as a primary long-term treatment
D. Therapeutic exercise
Rationale: Passive heat alone does not produce sustained functional improvements.
10. A precaution indicates which of the following?
A. Treatment is absolutely forbidden
B. Treatment requires special care or limitation
C. Treatment is unsafe under all conditions
D. Treatment has no risks
Rationale: Precautions allow use with modifications, unlike contraindications.
11. A contraindication means that a modality:
A. Requires patient consent
B. May be used briefly
C. Should not be used at all
D. Can be used with monitoring
Rationale: Contraindications indicate absolute prohibition due to risk.
