Type of breakthrough pain. Pain that is unpredictable and not associated with any activity or event.

54
Q

Patient barriers to effective pain management

A

Fear of addiction, worry about side effects, fear of tolerance (“wont be there when I need it”), take too many pills already, fear of injections, concern about not being a “good” patient, dont want to worry family and friends, may need more tests, need to suffer to be cured, pain is for past indescretions, inadequate education, reluctance to discuss pain, pain is inevitable, pain is part of aging, fear of disease progression, primary care providers and nurses are doing all they can, forget to take analgesics, fear of distracting primary health care providers from treating illness, primary health care providers have more important or ill patients to see, suffering in silence is noble and expected.

55
Q

Health Care provider barriers to effective pain management

A

Inadequate pain assessment, concern with addiction, opiophobia (fear of opioids), fear of legal repercussions, no visible cause of pain, patients must learn to live with pain, reluctance to deal with side effects of analgesics, fear of giving a dose that will kill the patient, not believing the patients report of pain, primary health care provider time constraints, inadequate reimbursement, belief that opioids mask symptoms, belief that pain is part of aging, overestimation of rates of respiratory depression.

56
Q

Health Care system barriers to effective pain management

Concern with creating addicts, ability to fill prescriptions, absolute dollar restriction on amount reimbursed for prescriptions, mail order pharmacy restrictions, nurse practitioners and physician assistants not used efficiently, extensive documentation requirements, poor pain policies and procedures regarding pain management, lack of money, inadequate access to pain clinics, poor understanding of economic impact of unrelieved pain.

57
Q

Physical dependence

A

A state of adaptation that is manifested by a drug class-specific withdrawal syndrom produced by abrupt cessasion, rapid dose reduction, decreasing blood level of the drug, or administration of an antagonist

58
Q

Drug tolerance

A

A state of adaptation in which exposure to a drug induces changes that result in a diminution of one or more of the drugs effects over time.

59
Q

Addiction

A

A primary, chronic, neurobiologic disease, with genetic, psychosocial, and environmental factors influencing its development and manifestations. Addictive behaviors include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving.

60
Q

Placebo

A

A medication or procedure that produces positive or negative effects in patients that are no related to the placebo’s specific physical or chemical properties.

61
Q

Pain clinics

A

Treat persons on an inpatient or outpatient basis; multidisciplinary approach to find the most effective pain relief measures.

62
Q

Palliative care

A

Care provided with the goal to live life fully with an incurable condition

63
Q

Hospice Care

A

Provided at the end of life; it emphasizes quality of life over quantity.

64
Q

Identify some principles to evaluate related to pain management

A

Evaluate the patient for the effectiveness of the pain management after an appropriate period of time; entertain new approaches if no relief; evaluate the patient’s perception of pain

65
Q

Pain is a protective mechanism warning of tissue injury and is largely a(n):

A

Subjective experience. Only the person knows if the pain is present and what the experience is like

66
Q

A substance that can cause analgesia when it attaches to opiate receptors in the brain is:

A

Endorphin. When the brain perceives pain, there is a release of inhibitory neurotransmitters such as endogenous opioids (endorphins) that hinder the transmission of pain and help produce an analgesic effect

67
Q

To adequately assess the quality of a patient’s pain, which question would be appropriate?

A

“Tell me what your pain feels like.” A patient’s self report of pain is the single most reliable indicator of the existence and intensity of pain.

68
Q

The use of patient distraction in pain control is based on the principle that:

A

The reticular formation can send inhibitory signals to gating mechanisms. The reticular activating system inhibits painful stimuli is a person receives sufficient or excessive sensory input; with sufficient sensory stimulation, a person is able to ignore or become unaware of pain.

69
Q

Teaching a child about painful procedures is best achieved by:

A

Relevant play directed toward procedure activities. Developmental differences are found among age groups; therefore, the nurse needs to adapt approaches for assessing a child’s pain and how to prepare a child for a painful procedure.

70
Q

Four physiological processes of nociceptive pain:

A

Transduction, Transmission, perception, modulation

71
Q

Transduction

A

Thermal, chemical or mechanical stimuli usually cause pain. Transduction converts energy produced by these stimuli into electrical energy.

72
Q

Histamine

A

Produced by mast cells causing capillary dilation and increases capillary permeability.

73
Q

Factors influencing pain for older adults.

A

Muscle mass decreases, body fat increases, and percentage of body water decreases.
Older adults frequently eat poorly, resulting in low serum albumin levels. Many drugs are highly protein bound.
A decline of renal and liver function. Results in reduced metabolism and excretion of drugs. May experience a greater peak effect and longer duration of analgesics.
Age related changes to skin such as thinning or loss of elasticity affect absorption rate of analgesics.

74
Q

True or False:

Infants cannot feel pain

A

False: Infants have the anatomical and functional requirements for pain processing by mid to late gestation

75
Q

True or False:

Infants are just as sensitive to pain as older children and adults.

A

True

76
Q

True or False:

Infants cannot express pain

A

False: Although infants cannot verbalize pain, they respond with behavioral cues and physiological indicators that are observable.

77
Q

True or False:

Infants must learn about pain from previous painful experiences

A

False: Pain requires no prior experience.

78
Q

True or False:
Use behavioral cues (facial expressions, cry, body movements) and physiological indicators of pain (changes in vitals) to reliably assess pain in infants

A

True

79
Q

Superficial or cutaneous pain

A

Pain resulting from stimulation of skin. Pain is of short duration and localized. It usually is a sharp sensation. Examples: Needlestick, small cut or laceration.

80
Q

Deep or Visceral Pain

A

Pain resulting from stimulation of internal organs. Pain is diffuse and radiates in several directions. Duration varies, but it usually lasts longer than superficial pain. Pain is sharp, dull, or unique to organ involved. Examples: Crushing sensation (angina pectoris), burning sensation (gastric ulcer)

81
Q

Referred pain

A

Common phenomenon in visceral pain because many organs themselves have no pain receptors. Entrance of sensory neurons from affected organ in same spinal cord segment as neurons from areas where individual feels pain; perception of pain in unaffected areas. Example: Myocardial infarction, which causes referred pain to the jaw, left arm, and left shoulder.

82
Q

Radiating Pain

A

Sensation of pain extending from initial site of injury to another body part. Feels as though it travels down or along body part. It is intermittent or constant. Example: Low back pain from ruptured intravertebral disk accompanied by pain radiating down leg from sciatic nerve irritation.

83
Q

Two types of sensory nerve fibers

A
  1. Fast myelinated A-delta fibers: send sharp, localized, distinct sensations
  2. Slow, small, unmyelinated C fibers: send poorly localized, burning, persistent pain
84
Q

Transmission

A

Sending of impulse across a sensory pain nerve fiber (nociceptor)

85
Q

Perception

A

The patient’s experience of pain

86
Q

Modulation

A

Inhibition of pain/ release of inhibitory neurotransmitters

87
Q

Gating Mechanism

A
  • in the central nervous system (CNS) regulate or block pain impulses.
  • Pain impulses pass through when a gate is open & are blocked when a gate is closed.
  • Closing the gate is the basis for non-pharmacological pain relief interventions.
88
Q

Safety guidelines for when a PCA pump is used.

A
  • The patient is the only person who should press the button to administer the pain medication when PCA is used.
  • Monitor the patient for signs & symptoms of oversedation and respiratory depression
