Which of the following best describes the physiological process of pain perception?
A. It involves the transmission of impulses from the periphery to the central nervous system.
B. It is solely dependent on the severity of the injury.
C. It is a purely emotional experience.
D. It is only perceived after tissue healing occurs.
Answer: A
Rationale: Pain perception involves the transmission of nociceptive impulses from peripheral
receptors to the central nervous system.
Question 2
What type of pain results from direct damage to body tissue?
A. Neuropathic pain
B. Nociceptive pain
C. Psychogenic pain
D. Phantom pain
Answer: B
Rationale: Nociceptive pain is caused by direct injury to body tissues, leading to activation of
nociceptors.
Question 3
Which of the following neurotransmitters is primarily associated with the transmission of pain
signals?
A. Serotonin
B. Dopamine
C. Substance P
D. Endorphins
Answer: C
Rationale: Substance P is a key neurotransmitter involved in the transmission of pain signals in
the central nervous system.
,Question 4
When a patient reports pain as a result of nerve damage, what type of pain is this classified as?
A. Acute pain
B. Chronic pain
C. Nociceptive pain
D. Neuropathic pain
Answer: D
Rationale: Neuropathic pain occurs due to damage or dysfunction in the nervous system, often
described as shooting, burning, or tingling.
Question 5
The gate control theory of pain suggests that:
A. Pain perception is entirely psychological.
B. Pain is a result of injury severity.
C. Pain signals can be modulated by competing sensory signals.
D. All pain signals reach the brain without interruption.
Answer: C
Rationale: The gate control theory posits that non-painful stimuli can close the "gates" to painful
input, thus reducing the perception of pain.
Question 6
What is the primary purpose of nociceptors?
A. To detect temperature changes
B. To respond to mechanical stimuli
C. To detect and respond to harmful stimuli
D. To modulate emotional responses
Answer: C
Rationale: Nociceptors are specialized sensory receptors that detect and respond to harmful
stimuli, signaling potential injury.
Question 7
, Which part of the brain is primarily responsible for the emotional response to pain?
A. Thalamus
B. Cerebral cortex
C. Limbic system
D. Medulla oblongata
Answer: C
Rationale: The limbic system processes emotions and is integral to the emotional response to
pain.
Question 8
Pain that lasts longer than six months and persists beyond the normal time of healing is classified
as:
A. Acute pain
B. Chronic pain
C. Subacute pain
D. Referred pain
Answer: B
Rationale: Chronic pain is defined as pain that persists for more than six months and is often
resistant to treatment.
Question 9
Which of the following is a common physiological response to acute pain?
A. Decreased heart rate
B. Increased blood pressure
C. Decreased respiratory rate
D. Vasodilation
Answer: B
Rationale: Acute pain typically activates the sympathetic nervous system, leading to increased
blood pressure and heart rate.
