Ch 15: Management of Patients with Oncologic Disorders (3)

Which type of hematopoietic stem cell transplantation (HSCT) is characterized by cells from a donor other than the patient? pg. 349

Allogeneic Explanation: If the source of donor cells is from a donor other than the patient, it is termed allogeneic. Autologous donor cells come from the patient. Syngeneic donor cells are from an identical twin. Homogenic is not a type of stem cell transplant.

A nurse is administering daunorubicin through a peripheral I.V. line when the client complains of burning at the insertion site. The nurse notes no blood return from the catheter and redness at the I.V. site. The client is most likely experiencing which complication? pg. 342

Extravasation Explanation: The client is exhibiting signs of extravasation, which occurs when the medication leaks into the surrounding tissues and causes swelling, burning, or pain at the injection site. Erythema is redness of the skin that results from skin irritation. Flare is a spreading of redness that occurs as a result of drawing a pointed instrument across the skin. Thrombosis is the formation of clot within the vascular system.

The client is receiving a vesicant antineoplastic for treatment of cancer. Which assessment finding would require the nurse to take immediate action? pg. 342

Extravasation Explanation: The nurse needs to monitor IV administration of antineoplastics (especially vesicants) to prevent tissue necrosis to blood vessels, skin, muscles, and nerves. Stomatitis, nausea/vomiting, and bone pain can be symptoms of the disease process or treatment mode but does not require immediate action.

For a client newly diagnosed with radiation-induced thrombocytopenia, the nurse should include which intervention in the care plan? pg. 378

Inspecting the skin for petechiae once every shift Explanation: Because thrombocytopenia impairs blood clotting, the nurse should inspect the client regularly for signs of bleeding, such as petechiae, purpura, epistaxis, and bleeding gums. The nurse should avoid administering aspirin because it may increase the risk of bleeding. Frequent rest periods are indicated for clients with anemia, not thrombocytopenia. Strict isolation is indicated only for clients who have highly contagious or virulent infections that are spread by air or physical contact.

A nurse is teaching a client about the rationale for administering allopurinol with chemotherapy. Which example would be the best teaching by the nurse? pg. 345, 383

It lowers serum and uric acid levels. Explanation: The use of allopurinol with chemotherapy is to prevent renal toxicity. Tumor lysis syndrome occurrence can be reduced with allopurinol's action of reducing the conversion of nucleic acid byproducts to uric acid, in this way preventing urate nephropathy and subsequent oliguric renal failure. Allopurinol does not stimulate the immune system, treat anemia, or prevent alopecia.

During which step of cellular carcinogenesis do cellular changes exhibit increased malignant behavior? pg. 326

Progression Explanation: Progression is the third step of carcinogenesis, in which cells show a propensity to invade adjacent tissues and metastasize. During promotion, repeated exposure to promoting agents causes the expression of abnormal genetic information, even after long latency periods. During initiation, initiators such as chemicals, physical factors, and biologic agents escape normal enzymatic mechanisms and alter the genetic structure of cellular DNA. No stage of cellular carcinogenesis is termed prolongation.

What should the nurse tell a client who is about to begin chemotherapy and is anxious about hair loss? pg. 363

The client should consider getting a wig or cap prior to beginning treatment. Explanation: If hair loss is anticipated and causing the client anxiety, a wig, cap, or scarf should be purchased before therapy begins. Alopecia develops because chemotherapy affects the rapidly growing cells of the hair follicles. Hair usually begins to grow again within 4 to 6 months after therapy. Clients should know that new growth may have a slightly different color and texture.

The nurse is caring for a client who is scheduled for chemotherapy. Which is the best statement the nurse can make about the client experiencing chemotherapy-induced alopecia? pg. 363

"The hair loss is usually temporary." Explanation: Alopecia associated with chemotherapy is usually temporary and will return after the therapy is completed. New hair growth may return unchanged, but there is no guarantee and color, texture, and quality of hair may be changed. There is no correlation between chemotherapy and delay in greying of hair. Use of wigs, scarves, and head coverings can be used by clients at any time during treatment plan.

The root cause of cancer is damage to cellular deoxyribonucleic acid (DNA) which can be caused by many factors, or carcinogens. What factors can be carcinogenic? Select all that apply. pg. 327

- dietary substances - environmental factors - viruses Explanation: Carcinogens include chemical agents, environmental factors, dietary substances, viruses, lifestyle factors, and medically prescribed interventions. Although age and gender may increase a person's risk for developing certain types of cancer, they are not carcinogens in and of themselves.

The oncology nurse is giving chemotherapy to a client in a short stay area. The client confides that they are very depressed. The nurse recognizes depression as which of the following? pg. 375

A normal reaction to the diagnosis of cancer. Explanation: Clients have many reactions, ranging from anxiety, fear, and depression to feelings of guilt related to viewing cancer as a punishment for past actions or failure to practice a healthy lifestyle. They also may express anger related to the diagnosis and their inability to be in control. While depression is understandable, it also needs to be acknowledged and treated if necessary. Depression is not a side effect of the neoplastic drugs nor is it an aberrant psychologic reaction to the chemotherapy.

A client is receiving external radiation to the left thorax to treat lung cancer. Which intervention should be part of this client's care plan? pg. 359

Avoiding using soap on the irradiated areas Explanation: Because external radiation commonly causes skin irritation, the nurse should wash the irradiated area with water only and leave the area open to air. No soaps, deodorants, lotions, or powders should be applied. A lead apron is unnecessary because no radiation source is present in the client's body or room. Skin in the area to be irradiated is marked to position the radiation beam as precisely as possible; skin markings must not be removed.

Which type of surgery is used in an attempt to relieve complications of cancer? pg. 337

Palliative Explanation: Palliative surgery is performed to relieve complications of cancer. Prophylactic surgery involves removing nonvital tissues or organs that are likely to develop cancer. Reconstructive surgery may follow curative or radical surgery and is carried out in an attempt to improve function or to obtain a more desirable cosmetic effect. Salvage surgery is an additional treatment option that uses an extensive surgical approach to treat the local recurrence of a cancer after the use of a less extensive primary approach.

The client is diagnosed with a benign brain tumor. Which of the following features of a benign tumor is of most concern to the nurse? pg. 326

Tumor pressure against normal tissues Explanation: Benign tumors grow more slowly than malignant tumors and do not emit tumor-specific antigens or proteins. Benign tumors do not metastasize to distant sites. Benign tumors can compress tissues as it grows, which can result in impaired organ functioning.

The nurse is evaluating the client's risk for cancer. The nurse should recommend the client change which lifestyle choice? pg. 329

eats red meat such as steaks or hamburgers every day Explanation: Dietary substances such as nitrate-containing and red meats appear to increase the risk of cancer. Exercising 30 minutes on 5 days or more is recommended for adults. Measures are taken to protect those people who work around radiation. Alcohol consumption recommendations include drink no more than one drink per day for women or two per day for men.

A client with ovarian cancer is ordered hydroxyurea, an antimetabolite drug. Antimetabolites are a diverse group of antineoplastic agents that interfere with various metabolic actions of the cell. What mechanism of action do antimetabolites interferes with? pg. 343

normal cellular processes during the S phase of the cell cycle Explanation: Antimetabolites act during the S phase of the cell cycle, contributing to cell destruction or preventing cell replication. They're most effective against rapidly proliferating cancers. Miotic inhibitors interfere with cell division or mitosis during the M phase of the cell cycle. Alkylating agents affect all rapidly proliferating cells by interfering with DNA; they may kill dividing cells in all phases of the cell cycle and may also kill nondividing cells. Antineoplastic antibiotic agents interfere with one or more stages of the synthesis of RNA, DNA, or both, preventing normal cell growth and reproduction.

A nurse is caring for a client who is receiving chemotherapy and has a platelet count of 30,000/mm3. Which statement by the client indicates a need for additional teaching? pg. 361

"I floss my teeth every morning." Explanation: A client with a platelet count of 30,000/mm3 is at risk for bleeding and shouldn't floss his teeth. Flossing may increase the risk of bleeding in a client with a platelet count less than 40,000/mm3. Using an electric razor is appropriate because doing so helps minimize the risk of cutting when shaving. Taking a stool softener helps decrease potential trauma to the GI tract that may cause bleeding. Removing throw rugs from the house helps prevent falls, which could lead to uncontrolled bleeding.

The nurse is caring for a client is scheduled for chemotherapy followed by autologous stem cell transplant. Which of the following statements by the client indicates a need for further teaching? pg. 349

"I hope they find a bone marrow donor who matches." Explanation: An autologous stem cell transplant comes from the client not from a donor. The doctor will remove the stem cells from the bone marrow before beginning chemotherapy and treat the client until most if not all the cancer is eliminated before reinfusing the stem cells. Clients are at risk for infection and will be closely monitored for at least 3 months, but not in protective isolation.

A 67-year-old client is admitted for diagnostic studies to rule out cancer. The patient is white, married, has been employed as a landscaper for 40 years, and has a 36-year history of smoking a pack of cigarettes daily. What significant risk factors does the nurse recognize this patient has? Select all that apply. pg. 329

- Age - Occupation - Cigarette smoking Explanation: Most cancer occurs in people older than 65 years. Although the overall rate of cancer deaths has declined, cancer death rates in Black men remain substantially higher than those among White men and twice those of Hispanic men. Excessive exposure to the ultraviolet rays of the sun, especially in fair-skinned people, increases the risk of skin cancers. Factors such as clothing styles (sleeveless shirts or shorts), the use of sunscreens, occupation, recreational habits, and environmental variables, including humidity, altitude, and latitude, all play a role in the amount of exposure to ultraviolet light. Tobacco smoke, thought to be the single most lethal chemical carcinogen, accounts for at least 30% of cancer deaths in humans (Fontham et al., 2009). Smoking is strongly associated with cancers of the lung, head and neck, esophagus, stomach, pancreas, cervix, kidney, and bladder and with acute myeloblastic leukemia. Marital status is not associated with risk for cancer.

After cancer chemotherapy, a client experiences nausea and vomiting. The nurse should assign highest priority to which intervention? pg. 344

Administering metoclopramide and dexamethasone as ordered Explanation: The nurse should assign highest priority to administering an antiemetic, such as metoclopramide, and an anti-inflammatory agent, such as dexamethasone, because it may reduce the severity of chemotherapy-induced nausea and vomiting. This intervention, in turn, helps prevent dehydration, a common complication of chemotherapy. Serving small portions of bland food, encouraging rhythmic breathing exercises, and withholding fluids for the first 4 to 6 hours are less likely to achieve this outcome.

A patient will be having an endoscopic procedure with a diagnostic biopsy. What type of biopsy does the nurse explain will remove an entire piece of suspicious tissue? pg. 335

Excisional biopsy Explanation: Excisional biopsy is most frequently used for small, easily accessible tumors of the skin, breast, and upper or lower gastrointestinal and upper respiratory tracts. In many cases, the surgeon can remove the entire tumor as well as the surrounding marginal tissues. The removal of normal tissue beyond the tumor area decreases the possibility that residual microscopic malignant cells may lead to a recurrence of the tumor. Incisional biopsy is performed if the tumor mass is too large to be removed. In this case, a wedge of tissue from the tumor is removed for analysis. Needle biopsy is performed to sample suspicious masses that are easily and safely accessible, such as some masses in the breasts, thyroid, lung, liver, and kidney. A core needle biopsy uses a specially designed needle to obtain a small core of tissue that permits histologic analysis.
