Week 8:NR283/NR283 Pathophysiology Week 8
1. A patient reports experiencing "fast pain" that is quickly followed by a "slow-wave pain." Which of the
following nerve fibers are responsible for transmitting these two types of pain signals?
A. A-delta fibers and C fibers
B. Nociceptors and mechanoreceptors
C. Paleospinothalamic tract and neospinothalamic tract
D. Radiation and conduction - ANSWER:Answer: A. A-delta fibers and C fibers
Explanation: The "fast pain" is transmitted by the large, myelinated A-delta fibers, while the "slow-wave
pain" is transmitted by the small, unmyelinated C fibers. This is in accordance with the gate control
theory of pain.
2. A patient with a history of chronic pain reports experiencing allodynia. Which of the following best
describes this symptom?
A. Reduced or lost tactile sensation
B. Extreme sensitivity to pain
C. Pain from non-injurious stimuli to the skin
D. Reduced or lost temperature sensation - ANSWER:Answer: C. Pain from non-injurious stimuli to the
skin
Explanation: Allodynia is the experience of pain from stimuli that would not normally be painful, such as
light touch to the skin. This is an example of altered pain sensitivity, where the patient's pain perception
is heightened beyond the normal response.
3. A patient is experiencing a severe, throbbing headache accompanied by nausea, vomiting, and
sensitivity to light and sound. Which type of headache is the patient most likely experiencing?
A. Tension-type headache
B. Cluster headache
C. Migraine
D. Temporomandibular joint pain - ANSWER:Answer: C. Migraine
Explanation: The symptoms described, including the severe, throbbing headache, nausea, vomiting, and
sensitivity to light and sound, are characteristic of a migraine headache. Migraines are a type of primary
headache disorder that can be debilitating for patients.
4. Select all the components of the neuromatrix theory of pain:
A. The brain identifies pain.
B. Transmission to the somatosensory cortex.
,C. Involvement of the limbic system.
D. Activation of the reticular activating system.
E. Involvement of brain stem centers. - ANSWER:Answer: A, B, C, E
Explanation: The neuromatrix theory of pain proposes that the brain itself identifies and processes pain,
with involvement of the somatosensory cortex, limbic system, and brain stem centers. The reticular
activating system is not a direct component of this theory.
5. A patient is experiencing a sudden, severe, and stabbing pain in the face, which is exacerbated by light
touch. This is most likely indicative of which type of pain syndrome?
A. Neuropathic pain
B. Neuralgia
C. Trigeminal neuralgia
D. Complex regional pain syndrome - ANSWER:Answer: C. Trigeminal neuralgia
Explanation: The sudden, severe, and stabbing facial pain that is triggered by light touch is characteristic
of trigeminal neuralgia, also known as tic douloureux. Trigeminal neuralgia is a type of neuropathic pain
affecting the trigeminal nerve.
6. A patient is experiencing persistent pain that has lasted for more than 6 months. Which of the
following is true about this patient's pain?
A. It is associated with autonomic and somatic responses.
B. It lacks the autonomic and somatic responses associated with acute pain.
C. It is self-limiting and will resolve within 6 months.
D. It is a type of acute pain. - ANSWER:Answer: B. It lacks the autonomic and somatic responses
associated with acute pain.
Explanation: Chronic pain, defined as pain that persists for longer than 6 months, is characterized by the
lack of autonomic and somatic responses that are typically seen with acute pain. Chronic pain is often
accompanied by debilitating responses, rather than the self-limiting nature of acute pain.
7. A patient is experiencing a life-threatening elevation in body temperature, along with muscle rigidity,
tachycardia, tachypnea, rhabdomyolysis, and respiratory and metabolic acidosis. Which condition is the
patient most likely experiencing?
A. Heat exhaustion
B. Heatstroke
C. Malignant hyperthermia
D. Neuroleptic malignant syndrome - ANSWER:Answer: C. Malignant hyperthermia
,Explanation: The symptoms described, including the life-threatening elevation in body temperature,
muscle rigidity, tachycardia, tachypnea, rhabdomyolysis, and respiratory and metabolic acidosis, are
characteristic of malignant hyperthermia, a rare and potentially fatal condition triggered by certain
anesthetic agents.
8. A patient reports experiencing a sudden, severe, and burning pain in the distribution of a specific
nerve. This is most likely indicative of which type of pain syndrome?
A. Neuropathic pain
B. Neuralgia
C. Trigeminal neuralgia
D. Complex regional pain syndrome - ANSWER:Answer: B. Neuralgia
Explanation: Neuralgia is a type of neuropathic pain characterized by a sudden, severe, and burning pain
that follows the distribution of a specific nerve. This is in contrast to trigeminal neuralgia, which is a
specific type of neuralgia affecting the trigeminal nerve.
9. Select all the mechanisms of heat production that contribute to thermoregulation:
A. Radiation
B. Conduction
C. Convection
D. Evaporation
E. Metabolism - ANSWER:Answer: A, B, C, D
Explanation: The mechanisms of heat production that contribute to thermoregulation are radiation,
conduction, convection, and evaporation. Metabolism is not a direct mechanism of heat production, but
it is a source of heat that the body must regulate.
10. A patient is experiencing a severe, throbbing headache that is accompanied by a sense of
restlessness and agitation. Which type of headache is the patient most likely experiencing?
A. Tension-type headache
B. Cluster headache
C. Migraine
D. Temporomandibular joint pain - ANSWER:Answer: B. Cluster headache
Explanation: The description of a severe, throbbing headache accompanied by a sense of restlessness
and agitation is characteristic of a cluster headache, a type of primary headache disorder that is often
unilateral and associated with autonomic symptoms.
11. A patient reports experiencing a reduced or lost ability to sense temperature. Which term best
describes this symptom?
, A. Hyperesthesia
B. Hyperalgesia
C. Hypothermia
D. Athermia - ANSWER:Answer: D. Athermia
Explanation: Athermia refers to the reduced or lost ability to sense temperature, which is a type of
altered pain sensitivity. This is in contrast to hypothermia, which refers to a lowered body temperature.
12. A patient is experiencing persistent pain that is accompanied by debilitating responses, such as
changes in mood and sleep patterns. Which type of pain is the patient most likely experiencing?
A. Acute pain
B. Chronic pain
C. Neuropathic pain
D. Referred pain - ANSWER:Answer: B. Chronic pain
Explanation: Chronic pain, defined as pain that persists for longer than 6 months, is characterized by the
lack of autonomic and somatic responses associated with acute pain, and is often accompanied by
debilitating responses, such as changes in mood and sleep patterns.
13. A patient reports experiencing an unpleasant hypersensitivity to touch. Which term best describes
this symptom?
A. Hyperesthesia
B. Hyperalgesia
C. Hypoesthesia
D. Allodynia - ANSWER:Answer: A. Hyperesthesia

which is a type of altered pain sensitivity. This is in contrast to hyperalgesia, which is an extreme
sensitivity to pain.
14. A patient is experiencing a severe, throbbing headache that is accompanied by nausea, vomiting, and
