SDK100 TMA 03 — Understanding and Treating Pain
Complete Practice Exam: 180 Questions with Detailed Explanations
Section 1: Foundations of Pain
Question 1
According to the International Association for the Study of Pain (IASP), pain is
defined as:
A) A purely physical response to tissue damage
B) An unpleasant sensory and emotional experience associated with actual or
potential tissue damage
C) A psychological condition with no physical basis
D) A normal physiological response that requires no treatment
Answer: B
Explanation: The IASP defines pain as "an unpleasant sensory and emotional
experience associated with actual or potential tissue damage, or described in
terms of such damage." This definition recognises that pain is both a physical and
,emotional experience, and it can occur even in the absence of identifiable tissue
damage.
Question 2
Which of the following best describes the biopsychosocial model of pain?
A) Pain is determined solely by biological factors such as tissue damage
B) Pain is influenced by biological, psychological, and social factors
C) Pain is entirely a psychological phenomenon
D) Pain is determined solely by social and cultural factors
Answer: B
Explanation: The biopsychosocial model recognises that pain is influenced by
biological factors (tissue damage, inflammation, genetics), psychological factors
(mood, beliefs, coping strategies, attention), and social factors (support networks,
culture, socioeconomic status). This model provides a comprehensive framework
for understanding and treating pain.
Question 3
What is the primary function of pain as a biological mechanism?
A) To cause suffering and distress
B) To signal actual or potential tissue damage and promote protective behaviour
C) To enable healthcare professionals to diagnose conditions
D) To provide a basis for psychological assessment
Answer: B
Explanation: Pain serves as a protective mechanism. It signals that tissue damage
has occurred or is imminent, promoting behaviours that protect the injured area
and facilitate healing. Without this warning system, individuals would be at risk of
ongoing injury without awareness.
,Question 4
Which of the following is NOT a recognised dimension of the pain experience?
A) Sensory-discriminative dimension
B) Affective-motivational dimension
C) Cognitive-evaluative dimension
D) Financial-economic dimension
Answer: D
Explanation: The pain experience has three recognised dimensions: the sensory-
discriminative dimension (location, intensity, quality of pain), the affective-
motivational dimension (emotional response, unpleasantness), and the cognitive-
evaluative dimension (meaning, appraisal, and cognitive processing). Financial-
economic factors are not a dimension of the pain experience itself.
Question 5
What is the difference between acute and chronic pain?
A) Acute pain is more severe than chronic pain
B) Acute pain is short-term and typically resolves with healing; chronic pain
persists beyond the normal healing time
C) Chronic pain is more severe than acute pain
D) There is no meaningful difference between acute and chronic pain
Answer: B
Explanation: Acute pain is short-term, typically lasting less than three months, and
resolves as healing occurs. Chronic pain persists beyond the normal healing time
(typically defined as three months or longer) and may continue even after the
initial injury has healed. Chronic pain often involves changes in the nervous system
that maintain the pain signal.
, Question 6
Which of the following is an example of nociceptive pain?
A) Phantom limb pain
B) Diabetic neuropathy
C) Pain from a broken bone
D) Post-herpetic neuralgia
Answer: C
Explanation: Nociceptive pain is caused by activation of nociceptors (pain
receptors) in response to tissue damage. Pain from a broken bone is nociceptive
pain. Phantom limb pain, diabetic neuropathy, and post-herpetic neuralgia are
examples of neuropathic pain caused by damage or dysfunction of the nervous
system.
Question 7
What is neuropathic pain?
A) Pain caused by tissue damage
B) Pain caused by damage or dysfunction of the nervous system
C) Pain that is always acute
D) Pain that is always psychological
Answer: B
Explanation: Neuropathic pain is caused by damage or dysfunction of the nervous
system, either in the peripheral nerves or in the central nervous system. It is often
described as burning, shooting, or electric shock-like, and it can persist long after
the initial injury has healed.
Question 8
Which of the following is an example of neuropathic pain?
