1 A patient has been diagnosed with hairy cell
leukemia The patient is to begin taking interferon
alfa 2b What will the nurse include in her
instructions to the patient concerning this drug?
Avoid drinking alcohol while taking the drug
A)
B) Continue to maintain maximal physical
activity
C) Increase fluid intake while taking the drug
Treat constipation with over-the-counter laxatives
D)
C
Trang 2Ans:
Feedback:
Interferon alfa 2b is metabolized in the kidney so adequate fluid intake is needed to promote metabolism and excretion of the drug as well as to minimize
common adverse effects including dry skin and
dizziness Maintaining maximal physical activity is a good idea but has no relationship to the use of the drug Fluids should be increased not decreased while taking the drug Constipation is not an associated adverse effect of this medication

2 The health care provider plans to inject an interferon
directly into the patient’s wart What interferon will the
nurse prepare?
Interferon alfa 2a (Roferon-A) A)
B) Interferon alfacon 1 (Infergen)
Interferon alfa n3 (Alferon N) C)
Interferon beta 1a (Avonex) D)
Ans: C
Feedback:
Trang 4Interferon alf n3 is used for intralesional treatment of warts Interferon alfa 2a is used in the treatment of leukemia Interferon alfacon 1 is used in the
treatment of chronic hepatitis C infection in adults Interferon beta 1a is used to treat multiple sclerosis in adults
3 A 30-year-old woman has been diagnosed with
leukemia and will be using an immune modulator for treatment What will be important to discuss with the patient when the nurse provides patient teaching about her treatment?
The need to continue oral contraceptives A)
The need to use barrier contraceptives while taking the drug
B)
The need to avoid sexual intercourse while taking the drug
C)
Trang 5D) The importance of taking an aspirin daily to
decrease the adverse effects of the drug
B Ans:
Trang 6Feedback:
A patient taking an immune modulator would be
advised to use barrier contraceptives to prevent
pregnancy The interaction of the immune modulator and the oral contraceptive may interfere with the oral contraceptive’s ability to work properly Asking
patients to avoid sexual intercourse is not necessary if barrier methods are properly used Daily aspirin would not decrease adverse effects of this drug
4 The nurse has an order to administer oprelvekin
(Neumega) to a patient for the first time Before
administering the drug, what allergy would the nurse want to specifically question the patient about?
A) Egg products
Escherichia coli–produced products
B)
Lactose intolerance C)
Trang 7Feedback:
D) Penicillin
B Ans:
The interleukins are produced using
deoxyribonucleic acid technology and E coli
bacteria Patients with known allergy to E coli
products should not receive oprelvekin The
allergies to penicillin, egg products, or lactose
intolerance would not be of concern with this drug
5 The physician has decided to prescribe T- and B-cell
suppressors for a patient diagnosed with psoriasis What drug will be ordered for this patient?
Alefacept (Amevive)
A)
Azathioprine (Imuran)
Trang 8Alefacept is prescribed for patients with severe
chronic plaque psoriasis Cyclosporine is used to suppress rejection in a variety of transplant situations Azathioprine is used to treat patients with rheumatoid arthritis and in prevention of rejection in renal
homotransplants Tacrolimus is used for prevention
of rejection after renal or liver transplantation
6 A patient who is receiving an immune suppressant
has been admitted to the unit What would be a priority action by the nurse?
Trang 9D) Provide support and comfort measures in
relation to adverse effects of the drug
Trang 10C Ans:
Feedback:
Patients taking immune suppressant drugs are more susceptible to infection because the patient’s normal body defenses will be diminished As a result, the priority action by the nurse would to protect the
patient from exposure to infection through room
selection, good hand hygiene, and taking care to avoid exposure to sick staff members Teaching will need to include avoiding crowded places and people with known infection and those working in soil Nutritional status is important as are comfort and support
measures and other instructions concerning the drug However, protecting the patient from infection should
be the priority action
7 A nurse is discussing interferon alfa 2b with a patient
What will the nurse encourage the patient to do while taking this drug?
To avoid crowds A)
Trang 11B) To increase salt intake
To decrease milk intake C)
To eat three meals a day D)

with this drug
Trang 12
8 A 70-year-old patient with acute myelocytic
leukemia is receiving sargramostim (Leukine) What
is a priority nursing action for this patient?
A) Providing a quiet environment
Increasing fluids B)
Providing comfort measures related to nausea
Trang 13A common adverse effect of this drug is vomiting and diarrhea Due to the patient’s age it would be important to keep him hydrated Vomiting and diarrhea can cause dehydration quickly in the elderly Providing a quiet environment and comfort measures for the nausea would be important but not as critical
as increasing fluids Diet is very important to this patient; however, usually this drug causes a loss of appetite Therefore, increasing fluids would be extremely important to the patient’s nutritional status
9 The nurse is caring for a patient in the immediate
postoperative period following cardiac transplantation who is receiving mycophenolate (CellCept) twice a day IV What will the nurse teach the patient regarding drug therapy? (Select all that apply.)
“The drug will be given orally as soon as possible
Trang 14“Ask a pharmacist about drug–drug interactions before taking any over-thecounter (OTC) drug.”
D)
“Never miss a dose of medication.”
E)
A, C, D, E Ans:
Feedback:
The nurse will explain that the IV medication will be changed to oral therapy when the patient is able to tolerate oral medications The patient will take the medication twice a day, not three times a day Care should be taken to never miss a dose The patient should avoid other medications that are hepatotoxic
or nephrotoxic due to a risk of increased toxicity so the patient should be taught to always consult a doctor or pharmacist before beginning an OTC drug Patients who have immune suppression must be taught how to reduce risk of infection, including avoiding people with contagious diseases, such as

The nurse administers aldesleukin to a patient
diagnosed with renal cell carcinoma When
assessing the patient a few days later, what
abnormal findings would the nurse attribute to the medication? (Select all that apply.)
A) Increased lymphocyte count
B) Increased red blood cell count
C) Increased platelet count
D) Irregular pulse rate
E) Increased blood pressure
Ans: A, C, D
Feedback:
colds or viruses
Trang 16Aldesleukin activates human cellular immunity and inhibits tumor growth through increases in
lymphocytes, platelets, and cytokines Common
adverse effects include hypotension, sinus
tachycardia, arrhythmias, as well as pruritus, nausea, vomiting, diarrhea, anorexia, GI bleeding, bone
marrow suppression, respiratory difficulties, fever, chills, pain, mental status changes, and dizziness There is no impact on red blood cell count It does not raise blood pressure
A) They stimulate B-lymphocyte activity
B) They interfere with multiplication of stem
cells
C) They stimulate growth and
differentiation of lymphoid cells into lymphocytes
Trang 17D) They interfere with the ability of viruses in
infected cells to replicate
Ans: D
Feedback:
Interferons are substances naturally produced and released by human cells that have been invaded by viruses They may also be released from cells in response to other stimuli, such as cytotoxic T-cell activity Interferons do not stimulate B-lymphocyte activity, interfere with multiplication of stem cells, nor do they stimulate growth and differentiation of lymphoid cells into lymphocytes
12
How do immune suppressants work when ordered for
a patient who has had an organ transplant?
A) Blocking normal effects of the immune
system
B) Stimulating immune system to fight off
infection
Trang 18C) Working with corticosteroids to enhance
transplantation (in which non–self-cells are
transplanted into the body and destroyed by the immune reaction) and in autoimmune disorders (in which the body’s defenses recognize self-cells as foreign and work to destroy them) in some cancers Options B, C, and D are distracters for this question
13 A patient has just been told that her cancer has
metastasized to her right kidney An interferon
(Aldesleukin) has been prescribed to treat this
metastasis The patient asks why this interferon is ordered What is the nurse’s best response?
Trang 19A) “Aldesleukin has been shown to protect
autologous tumor cells.”
B) “Aldesleukin has been shown to inhibit
tumor growth.”
C) “Aldesleukin has been shown to enhance
allogeneic stem-cell transplantation.”
D) “Aldesleukin has been shown to have a
direct proliferative effect on renal tumors.”
Ans: B
Feedback:
Trang 20Aldesleukin is prescribed for metastatic renal cell carcinoma in adults and treatment of metastatic melanomas (orphan drug use) working by activating human cellular immunity and inhibiting tumor growth through increases in lymphocytes, platelets, and cytokines Aldesleukin does not protect
autologous tumor cells, enhance allogeneic stemcell transplantation, or have a direct proliferative effect
on renal tumors

The nurse admits a patient who was newly
diagnosed with Kaposi’s sarcoma to the unit The physician has ordered an IV infusion of an
interferon What drug would be appropriate?
A) Interferon beta1a
B) Interferon gamma 1b
C) Interferon alfa 2b
Trang 22Interferons act to prevent virus particles from
replicating inside the cells They also stimulate interferon receptor sites on noninvaded cells to produce antiviral proteins, which prevent viruses from entering the cell In addition, interferons have been found to inhibit tumor growth and replication,
to stimulate cytotoxic T-cell activity, and to enhance the inflammatory response Options A and E are incorrect

A) They are substances naturally produced
and released by human cells that have been invaded by viruses
Trang 27B) They block the inflammatory reaction and
decrease initial damage to cells
C)
They are chemicals used to communicate between leukocytes and stimulate
immunity
D) They attach to specific receptor sites and
respond to very specific situations
Ans: C
Feedback:
Interleukins are chemicals produced by T cells to communicate between leukocytes and stimulate
cellular immunity and inhibit tumor growth
Immune suppressants block the inflammatory
reaction and decrease initial damage to cells
Interferons are naturally produced and released by human cells that have been invaded by viruses

melanoma Aldesleukin is an interleukin, used for metastatic renal cell carcinoma in adults; a
treatment of metastatic melanomas Interferon alfa 2b is indicated for hairy cell leukemia, melanoma, AIDS-related Kaposi’s sarcoma, chronic hepatitis B and C infections, intralesional treatment of
condyloma acuminatum in patients 18 years of age
or older Cyclosporine is a T and B cell suppressor and is indicated for prophylaxis for organ rejection
in kidney, liver, and heart transplants (used with corticosteroids); treatment of chronic rejection in patients previously treated with other
immunosuppressants; treatment of rheumatoid arthritis; and recalcitrant psoriasis
