list types of foods the immunosuppressed client should avoid

Raw food, fruits and veggies unless cooked.


list the fx of macrophages and neutrophils

Macrophages become active (phagocytic immune response) and engulf and destroy antigens.



discuss the patho of scleroderma

hardening of the skin.


list the common signs of inflammation

redness, swelling, warmth, pain, and decreased function


describe Raynaud's phenomenon

condition that is characterized by spasmodic construction of arteries supplying the extremities. affects fingers and toes, often only the fingers. cold and emotional stress can make the condition worse. cause is unknown.


discuss the nursing implications/client teaching for the nurse administering prednisone

take with food. take exactly how prescribed. do not stop it abruptly. avoid alcohol during therapy. avoid people with contagious infections. caution vaccinations. check blood glucose often


discuss the fx of basophils during an allergic reaction

basophils are involved in INFLAMMATION. they contain HISTAMINE, heparin, bradykinin, and serotonin.


list three precautions to include in the plan of care for the client who is immunosuppressed

no not eat raw uncooked food
cook fruits and veggies
wash hands/shower daily


discuss plasmapheresis

a procedure in which antibodies are removed from the blood.


discuss the "scratch test" that tests for allergies

A skin test that tests for allergies with the use of intradermal injections or scratching of the superficial layer.


define leukocytosis

condition where WBC increase by the number


discuss the priority of care for the client with a bee sting

take out bee stinger with a credit card. apply ice. elevate. antihistamine.


list the s/s in a client with an immunodeficiency

Frequent and recurrent pneumonia, bronchitis, sinus infections, ear infections, meningitis or skin infections. Inflammation and infection of internal organs. Blood disorders, such as low platelet counts or anemia.


give 3 examples of lymph tissue

white blood cells (leukocytes), bone marrow, and the thymus, spleen, and lymph nodes.


list the side effects of immune suppression



Identify the location in the body of the thymus, spleen, stomach, and liver

Thymus - center sternum
Spleen - Left middle quadrant
Bone Marrow
Appendix - end of Small intestine into large
lymph nodes everywhere
Tonsils and adenoids - back of throat


define desensitization, immunotherapy, and immunity

Immunotherapy is more trying to cure the body with meds to bring the body back to homeostasis.

Desensitization - consists of giving minute doses of allergens subQ. "allergy shots" are gradually increased to enable the client slowly develop an immunologic tolerance to the allergen.

Immunity - condition of being non-susceptible to a certain disease.


discuss the discharge teaching for the client with systemic lupus erythematous (SLE)

- avoid UV and sun exposure. sunscreen
- mild shampoo. avoid harsh hair treatments
- steroid cream for rash
- report peripheral/periorbital edema
- report evidence of infection
- avoid crowds
- risk w/childbearing age


how are rheumatoid arthritis (RA) and systemic lupus erythematous (SLE) similar

joint pain including swelling and tenderness. also energy levels are low


explain the lab test "culture and sensitivity"

lab test ordered when infection is suspected or known.

- identifies the pathogenic microorganism
- determines which tx will eliminate
- monitors the microorganisms response to therapy

do before prescribing medication


discuss the patho of systemic lupus erythematous (SLE)

- body produces antibodies against components of its own cells, such as the antinuclear antibody (ANA), and immune complex disease then follows


list three symptoms the client might have if having an allergic reaction to a medication

edema, dyspnea, anaphylaxis


list the side effects of anti-rejection medications

Kidney toxicity, neurotoxicity, hypertension, gout, high potassium levels, hyperlipidemia


list the vaccines that are recommended for the older adult

Hep A and B


describe the s/s of systemic lupus erythematous (SLE)

- fatigue/malaise
- alopecia
- blurred vision
- pleuritic pain
- anorexia, weight loss
- depression
- joint pain, swelling, tenderness


Difference between natural and artificial active immunity. example of each

Active Natural - Develops when the body produces antibodies in response to exposure to a live pathogen.

Active Artificial - Develops when a caving is given and the body produces antibodies in response to exposure to skilled or attenuated virus.


describe the physical assessment of a client with an immune-related disorder

check for fever, enlarged lymph nodes, fatigue, rashes, change in LOC, sore throat, cough.


list 3 functions of the immune system

defense, homeostasis, and surveillance.


discuss the documentation required after giving an immunization

administration of vaccines to include date, route, site, type, manufacturer, lot number, and expiration date of vaccine. Also document the name, address, and signature.

Include name, and title of the person administering the vaccine, and address of the facility where the permanent record is located.


explains the difference between helper T cells, B cells, natural killer cells, and suppressor T cells

T cells - move from bone marrow to thymus gland and become CD4 helper cells, suppressor cells, cytotoxic (natural killer cells), subtype of CD8 cells and MEMORY CELLS

B cells - migrate from bone marrow to lymphoid tissue. transform into plasma cells which make ANTIBODIES and MEMORY cells

Natural killer cells - cytotoxic T. Born just to kill bad things in the body. Only function.
