Transduction from site of stimulation of peripheral receptors to spinal cord.

Transmission up spinal cord.

Perception at cerebral cortex.

Modulation back down spinal cord.

Physiology of pain involves journey

2

Nociceptors are primary sensory nerves located in

  • Tendons
  • Muscles
  • Subcutaneous tissue
  • Epidermis
  • Skeletal muscles
3

refers to pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg.

Sciatica

4

is the study of functional changes in the body that occur in response to disease or injury. For example, if someone ingests a toxin, that toxin might be associated with a variety of physical changes, such as inflammation in the stomach lining or necrosis of the extremities. The field is designed to help people study the progress of disease so that they can quickly identify diseases and consider various treatment options.

progress of a disease changes the body, and how the changes can be treated or reversed.

Pathophysiology

5

the study of disease and its impact on the body

pathology

6

study of the body and its functions

physiology

7

To spread out from a central area. For example, sciatic pain may radiate outward from the lower back.

RADIATE

8

Chest pain that worsens when you breathe, cough or sneeze. Shortness of breath — because you are trying to minimize breathing in and out. A cough — only in some cases. A fever — only in some cases

Pleuritic chest pain

9

Perforated organ, appendix

Chemical tissue damage

10

burn, lose skin layers

Thermal tissue damage

11

edema, stone, tumor

Mechanical tissue damage

12

unwanted intrusive thoughts that cause anxiety or distress

Obsession

13

unwanted repetitive behavior patterns or mental acts intended to reduce anxiety

COMPULSION

14

Located in the dorsal horn, aka substantia gelatinosa, controls the stimulation of sensory tracts within the spinal cord

GATE

15

Pain assessment and management often referred to as.

fifth vital sign

16

an unpleasant sensory and emotional experience associated with actual and potential tissue damage

PAIN

17

arises in bone, joint, muscle, skin, and connective tissue. aching or throbbing in quality & is well localized.

somatic pain (nociceptive pain)

18

arises from organ, GI Tract & pancreas.

1.Tumor involment organ capsule causes aching & fairly well-localized pain.

2. Obstruction of hollow viscus, causes intermittent cramping & poorly localized pain.

visceral pain (nociceptive pain)

19

normal processing of stimuli that damage normal tissues or has the potential to do so if prolonged; usually responsive to nonopiods and or opioids.

Arises from somatic structures such as bone, joint, or muscle. Results from activation of normal neural systems.

Nociceptive pain

20

Occurs because of abnormal processing of sensory input

"neuropathic" pain can radiate when the nerve is compressed or damaged (example is spinal nerve root compression that is felt in the foot).

Neuropathic pain

21

Pain felt in a location away from the injury.
Often visceral pain, as many abdominal organs have no pain receptors.

(nociceptive and visceral) and I want to clarify that pain from a heart attack that is felt in other places is in fact referred pain. I used the term "radiate" and referred pain does radiate to areas other than the true source of the pain.

Referred pain

22

Pain felt in an amputated extremity

Phantom pain

23

Point at which a stimulus is "perceived" as pain

Pain threshold

24

may be intermittent or continuous pain lasting more than 6 months.

Clinical manifestations of chronic pain are not those of physiologic stress because patient adapts to pain,

but often reports symptoms of irritability, depression, withdrawal, or insomnia.

Persistent (chronic) pain

25

recent onset and results from tissue damage, is usually self-limiting, and ends when tissue heals (less than 6 months), .

physiologic signs associated with pain such as an increase in blood pressure, pulse rate, and respiration
May cause physiologic signs associated with pain.

Examination

49

nurse is assessing the degree of pain or discomfort a patient is feeling. Nurse knows that this will be dependent primarily on:

perception of the pain or discomfort

50

cause of the pain

51

The nurse is compelled to address and manage a patient’s pain level by which ethical principles? (Select all that apply.)

Nonmaleficence

Beneficence

52

The nurse is reviewing the pathophysiology of pain. Where does the perception of pain actually occur?

53

The nurse is assessing for objective findings are associated with the patient’s pain level. Which findings are commonly associated with acute pain? (Select all that apply.)

An elevated blood pressure

An elevated heart rate

54

Initiation of intravenous access can be a painful experience for the patient. As the needle is inserted into skin, the patient is calm. However, when the needle pierces the vein, the patient pulls the hand away. The time that the person endured the pain before outwardly responding is known as:

A. Pain tolerance.
B. Pain intolerance.
C. Pain perception.
D. Pain threshold

Pain tolerance.

Rationale: Pain tolerance is the duration or intensity of pain that can be endured before an outward response is noted. The pain threshold is the point at which pain is perceived.

55

1. Type and frequency of analgesic medications the patient takes
2. Patient's most recent vital signs (e.g., blood pressure and pulse rate)
3. Extent of tissue damage the patient has had
4. Report from the patient describing the pain experienced

Report from the patient describing the pain experienced

56

A patient had a knee replaced because of arthritis. He reports that he has not slept well in several nights. He states that he can't get comfortable. Today he is asking for pain medication more often. What might be a reason for this increase in pain?

1. Arthritis pain is variable; it can be mild one day and severe the next.
2. Pain tolerance decreases with sleep deprivation.
3. The anesthesia from surgery is wearing off.
4. The patient is using the pain medication to help him sleep during the day.

Pain tolerance decreases with sleep deprivation.

57

A patient complains of leg pain. Which question is pertinent to ask to gain additional information?

The nurse is compelled to address and manage a patients pain level by which ethical principles? Select all that apply:

A. Beneficence
B. Liberty
C. Autonomy
D. Nonmaleficence
E. Justice

Beneficence, Nonmaleficence

Rationale: The ethical principles of beneficence (the duty to benefit another) and nonmaleficence (the duty to do no harm) compel health care professionals to provide pain management and comfort.Liberty and justice are ethical principles that deal with fairness. Autonomy deals with the patients right to make decisions independently.

60

The nurse is assessing the degree of pain or discomfort a patient is feeling. The nurse knows that this will be dependent primarily on the:

A. Ability to explain the pain or discomfort
B. Perception of the pain or discomfort
C. Age of the individual

Perception of the pain or discomfort

Rationale: Individuals may perceive a stimulus differently, making the pain experience very individualized.

61

The nurse is attending an in-service on pain management for postoperative patients. Which statement regarding pain is true? Select all that apply:

B. Individuals from all cultures respond to pain similarly.
C. The pain response may be influenced by ones culture.
D. Individuals may express pain differently.
E. Pain management may vary depending on the source of pain.

Answers: C. The pain response may be influenced by ones culture., D. Individuals may express pain differently., E. Pain management may vary depending on the source of pain.

Rationale: Culture influences how an individual responds to pain. Pain tolerance is highly variable. Patients may need narcotics for postoperative pain, whereas muscle strains may respond well to anti-inflammatory medications. Pain is not predictable regardless of culture or ethnicity and cannot be stereotyped by culture.

62

Which findings by the nurse would produce the most accurate assessment of the severity level of a patient's pain?

A. The nurse's experience
B. The cause of the pain
C. The patient's subjective data
D. The patient's objective findings

the patient's subjective data

Rationale: The most accurate and reliable evidence of pain is the patient's report.

The nurse is assessing a patient who has pain with a sudden onset and a limited duration and that subsides as healing occurs. Which type of pain would this be considered?

A. Acute pain
B. Chronic pain
C. Cancer pain
D. Nonmalignant pain

Acute pain

Rationale: By definition, acute pain is pain that lasts less than 6 months.

64

When assessing the quality of a patient's pain, the nurse should ask which question?

A. "When did the pain start?"
B. "Is the pain a stabbing pain?"
C. "Is it a sharp pain or dull pain?"
D. "What does your pain feel like?"

"What does your pain feel like?"

Rationale: To assess the quality of a person's pain, have the patient describe the pain in his or her own words.

65

The nurse is reviewing the pathophysiology of pain. Where does the perception of pain actually occur?

A. The dorsal horn of the spinal cord
B. The parietal lobe of the cerebral cortex
C. The afferent (sensory) nerves
D. The visceral and somatic free nerve endings (nociceptors)

The parietal lobe of the cerebral cortex

Rationale: Pain is not actually perceived until the parietal lobe is stimulated.

66

The nurse is assessing for objective findings are associated with the patients pain level. Which findings are commonly associated with acute pain? Select all that apply:

A. The patient is crying
B. An elevated blood pressure
C. An elevated heart rate
D. Diaphoresis
E. The patient states a pain level of 8 out of 10 on pain scale
F.Vital signs stable

Answers: B. An elevated blood pressure, C. An elevated heart rate, D. Diaphoresis

Rationale: All of these are common objective findings associated with acute pain.Crying and pain level are subjective findings. Vital signs will most likely be elevated during acute pain.

67

The nurse is performing a pain assessment of a 4-year-old toddler. Which pain assessment scale would be best for this patient?

A. Visual Analog Scale
B. Numeric Pain Intensity Scale
C. Wong/Baker Faces Rating Scale
D. Pain Intensity Scale

Wong/Baker Faces Rating Scale

Rationale: This scale is works well for children over 3 years of age because it has pictures.

68

Assessment of circulation, motion, and sensation is done every 8 hours in a patient recovering from a laminectomy 3 days after surgery. The patient had the surgery for consistent low back pain. Now on day 3, the patient has a burning sensation on the lateral edge of the right foot. This is best described as:

Neuropathic pain.
Cellulitis is an interstitial infection. Nociceptive pain is usually associated with tissue destruction or damage. Neuropathy is connected to nerve-related pain. It would appear that a nerve is being disturbed as a result of the surgery or the initial disease process. Burning sensation is a classic presentation or complaint related to nerve pain.

69

Initiation of intravenous access can be a painful experience for the patient. As the needle is inserted into skin, the patient is calm. However, when the needle pierces the vein, the patient pulls the hand away. The time that the person endured the pain before outwardly responding is known
