Safety, Security and Comfort Needs of the Acutely
Ill Client:
PAIN
The 5th Vital Sign
Definitions of Pain
“Pain is whatever the experiencing
person says it is, existing whenever
he/she says it does.”
“An unpleasant sensory and emotional
experience associated with actual or
potential tissue damage or described in
terms of such damage.”
-Mc Caffery 1968
- Intl. Assoc. for the study of pain
Food for Thought
Costs $100 Billion each year
Longer hospitalization
Rehospitalizations
ER visits
Sick days
Permanent Disability
Only 30% of cancer patients get adequate
pain relief
15-20% of Americans have acute pain
25-30% of Americans have chronic pain
Leading cause disability for those < 45 y/o
The Mechanisms of Pain
TransductionTransmission- movement of pain
impulses
Perception- recognition of pain
Modulation- activation
The Mechanisms of Pain
TransductionConversion of mechanical, thermal or
chemical stimulus into a neuronal action.
Peripheral nerve sites- peripheral afferent
nociceptor (PAN)
Action Potential causes movement of pain
stimulus What causes it?
Nociceptive- Release of Chemicals
Neuropathic- Abnormal processing of stimuli by
the nervous system
The Mechanisms of Pain
Transmission- movement of pain
impulses from the site of transduction to
the brain.
Transmission along the nociceptor fibers to
the level of the spinal cord.
Dorsal horn processing. (Dermatomes)
Transmission to the thalamus and the cortex.
The Mechanisms of Pain
Perception- recognition of pain
However, there is no precise location where pain
perception occurs.
Individualized
Imagery is a good pain-reduction therapy.
Subjective
Sensory: Recognition that you have pain.
Affective: Emotional responses to pain.
Behavioral: How someone expresses or controls pain.
Cognitive: Person’s beliefs & attitudes about pain.
Sociocultural: Age, Gender, education level, culture
and support systems.
The Mechanisms of Pain
Modulation- activation of descending
pathways that either inhibit or facilitate
effects on pain transmission.
Types of Pain
Nociceptive Pain
Normal processing of stimuli that
damages or has the potential to
damage, normal tissues if prolonged.
Different types of origins:
Somatic Pain: Arises from bone, joint,
muscle, skin or connective tissue.
Visceral Pain: Arises from visceral organs,
such as pancreas or stomach.
Somatic Pain
Described as “achy”, stabbing, sharp
Examples:
Bone pain, fractures
Muscle tears, sprains
Joint pain
Soft tissue injury
Visceral Pain
Diffuse and difficult to localize if d/t
obstruction of hollow viscus
Sharp, aching when due to injury to other
visceral structures such as;
Pancreatitis
Kidney Stones
Menstrual Cramps
Bowel Obstruction
Neuropathic Pain
Multiple Pain Syndromes
Often difficult to treat.
Believed to be the abnormal firing of the
peripheral or central nervous system.
Often described as burning, stinging,
shooting, traveling, or electric-like.
Caused by phantom limb pain, complex
regional limb pain complex regional pain
syndromes, diabetic neuropathy, postherpetic neuralgia, or trigeminal neuralgia
Comparing Nociceptive & Neuropathic Pain
Normal processing of
stimuli that damages
normal tissue.
Responds to opioids or
nonopiods.
Somatic pain- arises
from bone, joint,
muscle, skin or
connective tissue
Visceral pain
Tumor involvement that
causes aching and is
fairly well-localized
Obstruction causes
intermittent cramping
and poor localized pain.
Abnormal processing by
peripheral or central
nervous system.
Responds to adjuvant
analgesics.

Transdermal (Fentanyl duragesic patch)
Parenteral: IV, IM, SQ
Nebulized
Rectal
Epidural/Intrathecal (Morphine, Fentanyl)
Pharmacology of Pain Management Cont’
How do Opioids work?
Opioids act on the opioid receptor sites and
activate endogenous pain suppression
systems in the CNS (Mu receptor sites).
Receptor sites are found in:
Dorsal horn of the spinal cord
Pituitary gland
GI tract
Endogenous & exogenous opioids control
pain by locking onto opioid receptor sites
and blocking the release of
neurotransmitters.
Pharmacology of Pain Management Cont’
How NSAID’s and Acetaminophen work?
Non-opioids include NSAID’s, Tylenol and Aspirin.
They act on the peripheral nerve endings at the site of
injury altering the prostaglandin system.
NSAID’s have an anti-inflammatory effect.
Acetaminophen does NOT have an anti-inflammatory
effect. Like ASA, it has analgesic and antipyretic
effects.
Side effects:
NSAID’s: GI irritation, possible nephrotoxicity.
Acetaminophen can cause hepatoxicity.

Important Definitions
Tolerance- an adaptive process due to exposure to
a drug over time. Results in a decrease response to
a drug’s effect over time.
Physical Dependence- a physiologic
phenomenon that should be expected in persons with
persistent use of certain drugs. Patients will
experience a withdrawal syndrome if a drug is
abruptly stopped, there is a rapid dose reduction, or if
the person is given a reversal agent. Withdrawal can
be prevented by gradual taper
Reversal Agents
Narcan- Opioids
Romazacon- Benzodiazapam
Important Definitions Cont.’
Pseudoaddiction- This is not true
addiction and is created by under
treatment of pain. A term used to
describe behaviors seen in persons who
fear or who are experiencing
uncontrolled pain and want to obtain
medication for adequate pain relief.
The “clock-watching”, requesting extra
opioids, and demanding behaviors are
eliminated when the pain is relieved.
Important Definitions Cont.’
Addiction- A primary, chronic,
neurobiological disease with genetic,
psychosocial and environmental factors.
Characteristics include:
Impaired control over drug use
Compulsive use
Continued use despite harm
The need to use an opioid for effects other than
for pain relief and craving.
Important Definitions Cont.’
Breakthrough PainTransitory increase in pain to greater than
moderate intensity which occurs on top of the
baseline pain.
Distinguished from:
Continuous or uncontrolled pain
Acute episodic pain.

Physiology of Cancer
A. Background
1. Normal Cell Growth includes two
events
a. Replication of cellular DNA
b. Mitosis (cell division)
Nursing Care of the Client with Cancer
2. Cell cycle is under control of cyclins, and
suppresor gene products which control
process by working with enzymes;
cyclins promote cell division
suppresor gene products limit cell
division
3. Forms the basis of how some
chemotherapeutic agents work against
cancers
Nursing Care of the Client with Cancer
Theories of Carcinogenesis (what causes cancer to
occur)
1. Cellular Mutation
a. Cells begin to mutate (change the DNA to unnatural
cell reproduction)
2. Oncogenes/Tumor Suppressor Genes Abnormalities
a. Oncogenes are genes that promote cell proliferation
and can trigger cancer
b. Tumor suppressor genes normally suppress
oncogenes but are damaged
3. Exposure to Known Carcinogens
a. Act by directly altering the cellular DNA (genotoxic)
b. Act by affecting the immune system (promotional)

Nursing Care of the Client with Cancer
Neoplasms: also called tumors (mass of new tissue that grows
independently of surrounding organs
1. Types of neoplasms
a. Benign
1. Localized growths respond to body’s homeostatic controls
2. Encapsulated
3. Stop growing when they meet a boundary of another
tissue
4. Can be destructive
b. Malignant
1. Have aggressive growth, rapid cell division outside the
normal cell cycle
2. Not under body’s homeostatic controls
3. Cut through surrounding tissues causing bleeding,
inflammation, necrosis (death) of tissue
Nursing Care of the Client with Cancer
Malignant tumors can metastasize
a. Tumor cells travel through blood or lymph
circulation to other body areas and invade tissues
and organs there.
1. Primary tumor: the original site of the
malignancy
2. Secondary tumor (sites): areas where
malignancy has spread i.e. metastasis (metastatic
tumor)
3. Common sites of metastasis are lymph nodes,
liver, lungs, bones, brain
4. 50 – 60 % of tumors have metastasized by time
primary tumor identified
b. Cancerous cells must avoid detection by immune
system
Nursing Care of the Client with Cancer
C. Malignant neoplasms can recur after surgical removal of primary
and secondary tumors and other treatments
D. Malignant neoplasms vary in differentiation.
a. Highly differentiated are more like the originating
tissue
b. Undifferentiated neoplasms consist of immature
cells with no resemblance to parent tissue and have no
useful function
E. Malignant cells progress in deviation with each
generation and do no stop growing and die, as do
normal cells
F. Malignant cells are irreversible, i.e. do not revert to
normal
G.Malignant cells promote their own survival by hormone
production, cause vascular permeability; angiogenesis;
divert nutrition from host cells

C. Palliation of symptoms: may involve terminal care if
client’s cancer is not responding to treatment
Nursing Care of the Client with Cancer
Treatment Options (depend on type of cancer)
alone or with combination
A.
Chemotherapy
1. Effects are systemic and kills the
metastatic cells
2. Often combinations of drugs in specific
protocols over varying time periods
Much more effective then a single agent
Consider the timing of the nadir of each drug
• The time when the bone marrow activity and WBC counts
are at their lowest levels after chemo
• Different times for different drugs
3. Cell-kill hypothesis: with each cell
cycle a percentage of cancerous cells
are killed but some remain; repeating
chemo kills more cells until those left
can be handled by body’s immune
system

Classes of Chemotherapy Drugs
Alkylating agents
1. Action: create defects in tumor DNA
2. Examples: Nitrogen Mustard, Cisplatin
Antimetabolites
1. Action: similar to metabolites needed for vital cell
processes

2. Examples: Methotrexate; 5 fluorouracil
3. Toxic Effects: nausea, vomiting, stomatitis, diarrhea,
alopecia, leukopenia
3. Antitumor Antibiotics
1. Action: interfere with DNA
2. Examples: Actinomycin D, Bleomycin
3. Toxic Effect: damage to cardiac muscle
Nursing Care of the Client with Cancer
4. Antimiotic agents
1. Action: Prevent cell division
2. Examples: Vincristine, Vinblastine
3. Toxic Effects: affects neurotransmission,
alopecia, bone marrow depression
5. Hormone agonist
1. Action: large amounts of hormones upset the
balance and alter the uptake of other hormones
necessary for cell division
2. Example: estrogen, progestin, androgen
6. Hormone Antagonist
1. Action: block hormones on hormonebinding tumors (breast, prostate,
endometrium; cause tumor regression
Decreasing the amount of hormones can decrease
the cancer growth rate
Does not cure, but increases survival rates
2. Examples: Tamoxifen (breast); Flutamide
(prostate)
3. Toxic Effects: altered secondary sex
characteristics
7. Hormone inhibitors
Aromatase inhibitors (Arimidex, Aromasin)
Prevents production of aromatase which is
needed for estrogen production
Used in post menopausal women
Side effects

Nursing Care of the Client with Cancer
Surgery
1. Diagnosis, staging, and sometimes treatment of cancer
2. May be prophylaxis or removal of at risk tissue or organ
prior to development of cancer (breast cancer)
3. Involves removal of body part, organ, sometimes with
altered functioning (e.g. colostomy)
4. Debulking (decrease size of) tumors in advanced cases
5. Reconstruction and rehabilitation (e.g. breast implant post
mastectomy)
6. Palliative surgery to improve the quality of life
Removal of tumor tissue that is causing pain or obstruction
5. Psychological support to deal with surgery as well as
cancer diagnosis
Nursing Care of the Client with Cancer
Radiation Therapy
1. Treatment of choice for some tumors to kill or
reduce tumor, relieve pain or obstruction
2. Delivery
a. Teletherapy (external): radiation delivered in
uniform dose to tumor
Beam radiation
b. Brachytherapy: delivers high dose to tumor and
less to other tissues; radiation source is placed in
tumor or next to it in the form of seeds
Destroy cancer cells with minimal exposure to normal cells
Cells die or are unable to divide
Radiation source within the patient so pt emits radiation for
a period of time and is a hazard to others
c. Combination
3. Goals
a. Maximum tumor control with minimal
damage to normal tissues
b. Caregivers must protect selves by using
shields, distancing and limiting time with
client, following safety protocols
Private room
Caution sign on the door for radioactive material
Dosimeter film badge by staff
No pregnant staff
Limit visitors to ½ hour per day and keep them at
least 6 ft from the source
Nursing Care of the Client with Cancer
4. Treatment Schedules
a. Planned according to radiosensitivity of tumor,
tolerance of client
b. Monitor blood cell counts
5. Side Effects
a. Skin (external radiation): blanching, erythema,
sloughing, breakdown
Use mild soak
Dry skin with a patting motion, not rubbing
Don’t use powders or lotions unless prescribed by
radiologist
Wear soft clothing over the site
Avoid the sun and heat
b. Ulcerated mucous membranes: pain, lack
of saliva (xerostoma)
c. Gastrointestinal: nausea and vomiting,
diarrhea, bleeding, sometimes fistula
formation
d. Radiation pneumonitis
1-3 months after treatment
Cough, SOB, fever
Treated with steroids to decrease inflammation
Nursing Care of the Client with Cancer
Monoclonal antibodies (inoculate
animal with tumor antigen and retrieve
antibodies against tumor for human)
Antibodies target specific substances
needed by the cancer cell for growth
(Herceptin for breast cancer)
Gene therapy
experimental
May insert gene into the tumor cells to
make them more susceptible to being
killed by antiviral agents
May insert genes for cytokines that
increase their effectiveness in killing
cancer cells
Angiogenesis inhibitor drugs
prevent new blood vessels from
forming and delivering blood to the
tissue
Nursing Care of the Client with Cancer
F. Bone Marrow Transplantation and Peripheral Blood Stem Cell
Transplantation
1. Stimulation of nonfunctioning marrow or replace bone marrow
2. Common treatment for leukemias
G. Pain Control
1. Includes pain directly from cancer, treatment, or unrelated
2. Necessary for continuing function or comfort in terminally ill
clients
3. Goal is maximum relief with minimal side effects
4. Multiple combinations of analgesics (narcotic and nonnarcotic) and adjuvants such as steroids or antidepressants;
includes around the clock (ATC) schedule with additional
medications for break-through pain
5. Multiple routes of medications
6. May involve injections of anesthetics into nerve, surgical
severing of nerves radiation
7. May need to progress to stronger pain medications as pain
increases and client develops tolerance to pain medication
Nursing Care of the Client with Cancer
Nursing Diagnoses for Clients with Cancer
A. Anxiety
1. Therapeutic interactions with client and family; community
resources such as American Cancer Society, “I Can Cope”
2. Availability of community resources for terminally ill (Hospice
care in-patient, home care)
B. Disturbed Body Image
1. Includes loss of body parts (e.g. amputations); appearance
changes (skin, hair); altered functions (e.g. colostomy); cachexic
appearance, loss of energy, ability to be productive
2. Fear of rejection, stigma
C. Anticipatory Grieving
1. Facing death and making preparations for death: will be
consideration
2. Offer realistic hope that cancer treatment may be successful
Nursing Care of the Client with Cancer
D. Risk for Infection
E. Risk for Injury
1. Organ obstruction
2. Pathological fractures
F. Altered Nutrition: less than body requirements
1. Consultation with dietician, lab evaluation of nutritional
status
2. Managing problems with eating: anorexia, nausea and
vomiting
3. May involve use of parenteral nutrition
G. Impaired Tissue Integrity
1. Oral, pharyngeal, esophageal tissues (due to chemotherapy,
bleeding due to low platelet counts, fungal infections such as
thrush)
2. Teach inspection, frequent oral hygiene, specific nonirritating products, thrush control
Nursing Care of the Client with Cancer
Oncologic Emergencies
A. Pericaridal Effusion and Neoplastic
Cardiac Tamponade
1. Concern: compression of heart by fluid
in pericardial sac, compromised cardiac
output
2. Treatment: pericardiocentesis
B.
Superior Vena Cava Syndrome
1. obstruction of venous system with
increased venous pressure and stasis; facial
and neck edema with slow progression to
respiration distress
Late signs are cyanosis, decreased cardiac output
and hypotension
2. Treatment: respiratory support; decrease
tumor size with radiation or chemotherapy
Compression of the superior vena cava in SVC
syndrome
C. Sepsis and Septic Shock
1. Early recognition of infection
Patients at risk secondary to low WBC and
impaired immune system
2. Treatment: prompt intervention with
antibiotics and vasopressors
D. DIC disseminated intravascular
coagulation
Triggered by severe illness, usually sepsis
in cancer patients
Abnormal clotting uses up existing clotting
factors and platelets quickly then the pt
hemorrhages
Mortality rate is 70%
Prevention of sepsis is key
Nursing Care of the Client with Cancer
E. Spinal Cord Compression
1. Pressure from expanding tumor or
vertebral collapse can cause irreversible
paraplegia
2. Back pain initial symptom with
progressive paresthesia and paralysis
Paralysis is usually permanent
3. Treatment: early detection
High dose corticosteroid to decrease the swelling
radiation or surgical decompression
F.Obstructive Uropathy
1. Concern: blockage of urine flow;
undiagnosed can result in renal failure
2. Treatment: restore urine flow
G. Hypercalcemia
1. High calcium (normal 9-10.5) usually from bone metastases
2. May also come from cancer of the lung, head, neck, kidney
and lymph nodes that secrete parathyroid hormone that causes
the bone to release calcium
2. Symptoms include fatigue, muscle weakness, polyuria,
constipation, progressing to coma, seizures
3. Treatment
restore fluids with intravenous saline which also increases the
excretion of calcium
loop diuretics increase calcium excretion
Calcium chelators such as mithracin
Inhibit calcium resorption from the bone with calcitonin,
diphosphonate
H.
Tumor Lysis Syndrome
1. Occurs with rapid necrosis of tumor cells
with chemotherapy
When tumor cells die they release potassium and
purines
Potassium (norm 3.5-5.5) elevation causes cardiac
arrhthymias, muscle weakness, twitching, cramps
Purines convert to uric acid which causes renal
failure, flank pain, gout when elevated above 10
mg/dl
Hyperphosphatemia with secondary to
hypocalcemia causes heart block, HTN, renal failure
Treatment
Hydration
Instruct pt to increase fluid intake before
and after chemo
May need IV hydration
Diuretics to increase urine flow
Allopurinol to increase uric acid excretion
May need dialysis
Nursing Care of the Client with Cancer
I. SIADH (Syndrome of Inappropriate Antidiuretic Hormone
Secretion)
1. Ectopic ADH production from tumor leads to excessive
hyponatremia
2. holds onto too much fluid which decreases sodium level
(normal 135-145)
3. Symptoms
Weakness, muscle cramps, fatigue, ALOC, headache, seizures
2.
Treatment: restore sodium level
Fluid restriction
Increase sodium
Antibiotic demeclocycline works in opposition to ADH
Limits ADH effect on distal renal tubules so they can excrete water
