Brachytherapy

2
Q

Internal radiation is used to get the radiation where?

A

Close to the cancer or target tissue INSIDE the body

3
Q

Does the client emit radiation during internal radiation?

A

YES and they are hazardous to others

4
Q

Unsealed internal radiation causes the patient to emit radiation how?
How long is it radioactive?
How is it given?

A

Through body fluids
24-48 hours
IV or PO

5
Q

Sealed/solid internal radiation causes the patient to emit radiation how?
How is it given?

A

Patient emits it! But the body fluids are not radioactive

By a permanent or temporary implant places close or inside the tumor

6
Q

Assume that all radiation patients what in regards to NCLEX?

YES - can be absorbed through hands

38
Q

How do Biologic Response Modifiers (BRMs) work?

How is this different than chemo?

A

They enhance/use our own immune system to fight and hope to kill the cancer

Chemo acts directly on the cancer to kill it

Decreased immunity, especially when taken for cancer

45
Q

What are the primary treatments for hematologic cancers?

Why else might they be used?

A

Bone marrow and stem cell transplant

May be used as a rescue treatment with C/R destroy too many cells

46
Q

What is the difference between bone marrow transplant and stem cell transplant?

A

Bone marrow: Stem cells are collected from bone marrow

Stem cell: Stem cells are collected from the blood stream

BOTH refer to stem cells!

47
Q

Who can donate stem cells?

A

The patient themselves, a maternal/match donor, or identical twin

48
Q

How are stem cells given?

How do they work?

A

Stem cells are given into a vein (like a blood transfusion) and over time they settle in the bone marrow and produce healthy blood cells

49

What are the 2 major complications of stem cell transplant?

A

GVHD

Infection - Most immunosuppressed patients we can get!!!

50
Q

What is graft vs host disease (GVHD)?

Q

What is the #1 cause of cancer related deaths?

A

INFECTION - Need to treat ASAP

54
Q

General ways to prevent infection in cancer patients

A

Private room, had washing, own supplies (tools, cups, etc), limit visitors/nurses, coughing and deep breathing, no fresh flowers/plants, avoid crowds, avoid raw fruits/veggies, only drink fresh water - old water if sitting out for more than 15 mins

Change dressings and IV tubing daily, don’t share toiletries, bathe moist areas twice a day (groin and underarms)

55
Q

What could a slight increase and temperature indicate in this patient?
When should you tell your clients to come into the hospital?

Key thing to consider with this?

A

Sepsis!!

Come in for a temp greater than 100.4

*Look for lower increases too because immunosuppressed patients don’t usually have a spike in temp

56
Q

What is the best way to assess neutropenia?

What is normal?

A

Absolute Neutrophil Count (ANC) - how many WBCs are neutrophils

Normal: 2200-7700 cells/mm3

Below 24% Hct (normal 35-50)

69
Q

What is an important factor to check when giving RBC or platelets to cancer patients?

What to we do to prevent this?

A

They need to be cytomegalovirus (CMV) NEGATIVE - this is a type of herpes virus that we worry about with transmission to a fetus

About 50% of donated blood has this!

We test the blood and do a leukoreduction to make it safe

70
Q

Never infuse ____ platelets!!
Why?
How should they be administered?

A

NEVER INFUSE COLD PLATELETS! They spleen will reject them

They need to be room temperature

71
