Q

lines for chemo

A
  • A central catheter is usually placed for chemotherapy or laboratory blood testing.

22
Q

complications: Chemotherapy‑induced peripheral neuropathy nursing actions

A
  • Loss of sensory or motor function of peripheral nerves
  • Monitor in hands and feet, loss of taste, and constipation.
  • Monitor for orthostatic hypotension.
  • Teach the client how to prevent injury, including falls, and that loss of sensation makes the client unaware of heat, cold, or pressure.
  • Inform regarding risk of erectile dysfunction and treatment options.
23
Q

radiation

A
  • One of the oldest nonsurgical methods of cancer treatment
  • 50% of all cancer patients will receive radiation therapy at some point in their treatment
  • Cells damaged by radiation either die or become unable to divide.
  • Gamma rays are used most commonly because of their ability to penetrate tissues and damage cells.
24
Q

radiation: teletherapy

A

distance treatment, the radiation source is external to the patient.

25
Q

radiation: Brachytherapy

A

internal radiation that is placed close to the target tissue.
- This is done via placement in a body orifice (vagina) or body cavity (abdomen) or delivered via IV such as with radionuclide iodine, which is absorbed by the thyroid

26
Q

nursing actions brachytherapy

A
  • Place the client in a private room away from other clients when possible.
  • Place a sign on the door warning of the radiation source.
  • Wear a dosimeter film badge that records personal amount of radiation exposure.
  • Limit visitors to 30-min visits, and have visitors maintain a distance of 6 feet from the source.
  • Visitors and health care personnel who are pregnant or under the age of 18 should not come into contact with the client or radiation source.
  • flush urine 3 times
  • lien dispose of
  • Wear a lead apron while providing care keeping the front of the apron facing the source of radiation.
  • Follow protocol for proper removal of dressings and bed linens from the room.

  • Instruct the client to call the nurse for assistance with elimination.
  • Instruct the client and family about radiation precautions needed in health care and home environments.
27
Q

External Radiation (Teletherapy)

A
  • Delivered in small doses over several weeks and aimed at the body from an external source.
  • Unlike internal radiation, the client is not radioactive and is not hazardous to others.
  • Monitor for radiation injury to skin and mucous membranes and implement a skin care regimen.( keep skin moist)
  • Radiation will affect only the area getting treatment
28
Q

Radiation will affect only the area getting treatment: skin mouth neck

A
  • Skin: blanching ( takes a long time), erythema, desquamation (flaking), sloughing, hemorrhage
  • Mouth: mucositis, dry mouth
  • Neck: difficulty swallowing, (dysphagia)
  • Abdomen: gastroenteritis, Diarrhea, dyspnea
  • Gently wash the skin over the irradiated area with mild soap and water.
  • Dry the area thoroughly using patting motions.(no towels)
29
Q

external radiation: nursing actions

A
  • Do not remove or wash off radiation tattoos (markings) used to guide therapy.
  • Do not apply powders, ointments, lotions, deodorants, or perfumes to the irradiated skin.
  • Wear soft clothing. Avoid tight or constricting clothes.
  • Do not expose the irradiated skin to sun or a heat source.
  • Inspect skin for evidence of damage and report to the provider.
30
Q

pain

A
  • Management of cancer pain is necessary to optimize quality of life for a client who has cancer.
  • Not all clients who have cancer have pain.
  • Either the tumor or the treatment can cause cancer pain.
  • Tumor pressure or cell invasion can cause direct tissue, bone, and nerve pain.
  • Surgery, radiation, chemotherapy, and inactivity can also cause cancer pain.
31
Q

qualities of pain

A
  • Pain is subjective and can indicate tissue injury or impending tissue injury.
  • Pain can have physical and emotional components.

32
Q

neuropathic

A

Due to nerve damage
Numb, tingling, shooting, burning, or radiating

33
Q

Visceral/Deep

A

Occurs in internal organs
Can be difficult to identify
Deep, sharp pain

34
Q

Somatic

A

Occurs in bone or connective tissues

35
Q

Palliative Management of Pain

A
  • Provides comfort and reduce pains rather than to curing the cancer.
  • The goal is to reduce pain to improve quality of life while maintaining dignity and mental clarity.
36
Q

METHODS OF PAIN MANAGEMENT:

A
  • Surgery
  • Chemotherapy

radiation therapy
- can reduce pain by removing the tumor or reducing its size, which can alter pressure on adjacent tissues or organs.

37
Q

medications for pain

A

NSAIDs
Opioids
Antidepressants
Anticonvulsants
Corticosteroids
Local anesthetics

Some clients who have cancer pain require regular use of analgesics for pain control.

Q

Opioids

A

Morphine
Meperidine
Hydromorphone
Oxycodone
Fentanyl
Combinations, such hydrocodone with acetaminophen, for breakthrough pain

39
Q

routes for opioids

A
  • The parenteral route is best for immediate, short-term relief of acute pain.
  • The oral route is better for chronic, non-fluctuating pain.
40
Q

Monitor and intervene for adverse effects of opioid use:

A
  • constipation, orthostatic hypotension, urinary retention, nausea, vomiting, and sedation
  • Monitor for respiratory depression.
  • Have naloxone available to reverse effects.
  • Administer stimulant laxatives to prevent opioid-induced constipation.
  • The patient may build up a tolerance to pain medications and require increased dosages
41
Q

Supportive Therapy

A
  • In addition to cancer treatment, the client can require assistance for altered body function or to meet emotional and spiritual needs.
  • Provide alternate means of communication for clients who have cancer affecting the mouth, throat, larynx, or vocal cords.
  • Consult physical therapy, and genetic or other counseling services as indicated.
