MS3 - Ch. 15: Oncologic Disorders

The clinic nurse is caring for a client who has just been diagnosed with a tumor. The client says to the nurse "The doctor says my tumor is benign. What does that mean?" What is the nurse's best response?

"Benign tumors don't usually cause death." Benign tumors remain at their site of development. They may grow large, but their growth rate is slower than that of malignant tumors. They usually do not cause death unless their location impairs the function of a vital organ, such as the brain.

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?

"I floss my teeth every morning." 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.

A client is recovering from a craniotomy with tumor debulking. Which comment by the client indicates to the nurse a correct understanding of what the surgery entailed?

"I guess the doctor could not remove the entire tumor." Debulking is a reference made when a tumor cannot be completely removed, often due to its extension far into healthy tissue. Without complete removal, this is not a cure and, the cancer cells will continue to replicate and require adjuvant therapies to prevent further invasion. The physician, not the nurse, will need to clarify the details of the surgery.

A client receiving chemotherapy has a nursing diagnosis of Deficient diversional activity related to decreased energy. Which client statement indicates an accurate understanding of appropriate ways to deal with this deficit?

"I'll play card games with my friends." During chemotherapy, playing cards is an appropriate diversional activity because it doesn't require a great deal of energy. To conserve energy, the client should avoid such activities as taking long trips, bowling, and eating in restaurants every day. However, the client may take occasional short trips and dine out on special occasions.

A patient will be receiving radiation for 6 weeks for the treatment of breast cancer and asks the nurse why it takes so long. What is the best response by the nurse?

"It will allow time for the repair of healthy tissue." In external-beam radiation therapy (EBRT), the total radiation dose is delivered over several weeks in daily doses called fractions. This allows healthy tissue to repair and achieves greater cell kill by exposing more cells to the radiation as they begin active cell division. Repeated radiation treatments over time (fractionated doses) also allow for the periphery of the tumor to be reoxygenated repeatedly, because tumors shrink from the outside inward. This increases the radiosensitivity of the tumor, thereby increasing tumor cell death.

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?

"The hair loss is usually temporary." 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.

A patient is scheduled for cryoablation for cervical cancer and tells the nurse, "I am not exactly sure what the surgeon is going to do." What is the best response by the nurse?

"The surgeon is going to use liquid nitrogen to freeze the area." Cryoablation is the use of liquid nitrogen or a very cold probe to freeze tissue and cause cell destruction. It is used for cervical, prostate, and rectal cancers. Chemosurgery is the use of medication. Laser surgery is the use of a laser. Radiofrequency ablation is the use of thermal energy.

A nurse is assessing a 75-year-old woman who had a total hysterectomy when she was 30 years old and normal Pap test results for the past 10 years. The client asks about continuing the Pap test. What is the best response by the nurse?

"You may choose to discontinue this test." The American Cancer Society recommendations for women 66+ years or older who have had normal Pap tests for 10 years and who have had a total hysterectomy may choose to stop having Pap tests for cervical cancer screening.

A young female client has received chemotherapeutic medications and asks about any effects the treatments will have related to her sexual health. The most appropriate statement by the nurse is

"You will need to practice birth control measures." Following chemotherapy female clients may experience normal ovulation, early menopause, or permanent sterility. Clients are advised to use reliable methods of birth control until reproductivity is known.

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?

A normal reaction to the diagnosis of cancer. 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.

Following surgery for adenocarcinoma, the client learns the tumor stage is T3,N1,M0. What treatment mode should the nurse anticipate?

Adjuvant therapy is likely. T3 indicates a large tumor size, with N1 indicating regional lymph node involvement so treatment is needed. A T3 tumor must have its size reduced with adjuncts like chemotherapy and radiation. Although M0 suggest no metastasis, following with adjuvant (chemotherapy or radiation therapy) treatment is indicated to prevent the spread of cancer outside the lymph to other organs. The tumor stage IV wound be indicative of palliative care. A repeated biopsy is not needed until after treatment is completed.

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

Administering metoclopramide and dexamethasone as ordered 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.

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

Allogeneic 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.

The nurse is conducting a screening for familial predisposition to cancer. Which element should the nurse note as a possible indication of hereditary cancer syndrome?

An aunt and uncle diagnosed with cancer The hallmarks of hereditary cancer syndrome include cancer in two or more first-degree or second-degree relatives, early onset of cancer in family members younger than age 50, the same type of cancer in several family members, individual family members with more than one type of cancer, and a rare cancer in one or more family members.

Which of the following is a term used to describe the process of programmed cell death?

Apoptosis Apoptosis is the innate cellular process of programmed cell death. Mitosis is the phase of the cell cycle in which cell division occurs. Carcinogenesis is the process by which cancer arises. Angiogenesis is the process by which a new blood supply is formed.

The nurse is providing client teaching for a client undergoing chemotherapy. What dietary modifications should the nurse advise?

Avoid spicy and fatty foods. The nurse advises a client undergoing chemotherapy to avoid hot and very cold liquids and spicy and fatty foods. The nurse also encourages the client to have small meals and appropriate fluid intake.

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?

Avoiding using soap on the irradiated areas 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.

A client undergoes a biopsy of a suspicious lesion. The biopsy report classifies the lesion according to the TNM staging system as follows: Tis, N0, M0. What does this classification mean?

Carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis Tis, N0, M0 denotes carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis. No evidence of primary tumor, no abnormal regional lymph nodes, and no evidence of distant metastasis is classified as T0, N0, M0. If the tumor and regional lymph nodes can't be assessed and no evidence of metastasis exists, the lesion is classified as TX, NX, M0. A progressive increase in tumor size, no demonstrable metastasis of the regional lymph nodes, and ascending degrees of distant metastasis is classified as T1, T2, T3, or T4; N0; and M1, M2, or M3.

Which oncologic emergency involves the accumulation of fluid in the pericardial space?

Cardiac tamponade Cardiac tamponade is an accumulation of fluid in the pericardial space. DIC is a complex disorder of coagulation and fibrinolysis that results in thrombosis and bleeding. SIADH is a result of the failure in the negative feedback mechanism that normally regulates the release of antidiuretic hormone (ADH). Tumor lysis syndrome is a rapidly developing oncologic emergency that results from the rapid release of intracellular contents as a result of radiation- or chemotherapy-induced cell destruction of large or rapidly growing cancers such as leukemia.

Which occurs when fluid accumulates in the pericardial space and compresses the heart?

Cardiac tamponade Cardiac tamponade is an accumulation of fluid in the pericardial space. SVCS occurs when the superior vena cava is compressed or invaded by a tumor, lymph nodes are enlarged, intraluminal thrombosis obstructs venous circulation, or drainage occurs from the head, neck, arms, and thorax. SIADH is the continuous, uncontrolled release of ADH. DIC is a complex disorder of coagulation or fibrinolysis that results in thrombosis or bleeding.

A client diagnosed with acute myelocytic leukemia has been receiving chemotherapy. During the last 2 cycles of chemotherapy, the client developed severe thrombocytopenia requiring multiple platelet transfusions. The client is now scheduled to receive a third cycle. How can the nurse best detect early signs and symptoms of thrombocytopenia?

Closely observe the client's skin for petechiae and bruising. The nurse should closely observe the client's skin for petechiae and bruising. Daily laboratory testing may not reflect the client's condition as quickly as subtle changes in the client's skin. Performing a cardiovascular assessment every 4 hours and checking the clients history for a congenital link to thrombocytopenia don't help detect early signs and symptoms of thrombocytopenia.

The nurse is conducting a community education program using the American Cancer Society's colorectal screening and prevention guidelines. The nurse determines that the participants understand the teaching when they identify that people over the age of 50 should have which screening test every 10 years?

Colonoscopy Recommendations for screening for colorectal cancer include a screening colonoscopy every 10 years. Fecal occult blood tests should be completed annually in people over age 50. The test for PSA is used as a screening tool for prostate cancer. A Pap test is a screening tool for cervical cancer.

The drug interleukin-2 is an example of which type of biologic response modifier?

Cytokine Other cytokines include interferon alfa and filgrastim. Monoclonal antibodies include rituximab, trastuzumab, and gemtuzumab. Retinoic acid is an example of a retinoid. Antimetabolites are cell cycle-specific antineoplastic agents.

While administering cisplatin to a client, the nurse assesses swelling at the insertion site. What is the nurse's first action?

Discontinue the intravenous medication. If extravasation of a chemotherapeutic medication is suspected, the nurse immediately stops the medication. Depending on the drug, the nurse may then attempt to aspirate any remaining drug, apply a warm or cold compress, administer a neutralizing solution, or all these measures.

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?

Extravasation 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 nurse is caring for a client with cancer who is treating her cancer with deep-tissue massage in addition to radiation therapy. The nurse documents the use of which therapy on the client's chart?

Integrative medicine Integrative medicine is the use of therapies in conjunction with conventional medicine. This is also known as complementary medicine. Alternative therapies are used instead of conventional medicine.

Which of the following is a characteristic of a malignant tumor?

It gains access to the blood and lymphatic channels. By this mechanism, the tumor metastasizes to other areas of the body. Cells of malignant tumors are undifferentiated. Malignant tumors demonstrate variable rate of growth; however, the more anaplastic the tumor, the faster its growth. A malignant tumor grows at the periphery and sends out processes that infiltrate and destroy surrounding tissues.

What disadvantages of chemotherapy should the patient be informed about prior to starting the regimen?

It targets normal body cells as well as cancer cells. Chemotherapy agents affect both normal and malignant cells; therefore, their effects are often widespread, affecting many body systems.

Which is a growth-based classification of tumors?

Malignancy Tumors classified on the basis of growth are described as benign or malignant. Tumors that are classified on the basis of the cell or tissue of origin are carcinomas, sarcomas, lymphomas, and leukemias.

The nurse performs a breast exam on a client and finds a firm, non-moveable lump in the upper outer quadrant of the right breast that the client reports was not there 3 weeks ago. What does this finding suggest?

Malignant tumor A fast-growing lump is suggestive of a malignant tumor. Metastasis can only be determined by cytology, not by palpation.

In which phase of the cell cycle does cell division occur?

Mitosis Cell division occurs in mitosis. RNA and protein synthesis occurs in the G1 phase. DNA synthesis occurs during the S phase. DNA synthesis is complete, and the mitotic spindle forms in the G2 phase.

The nurse working on a bone marrow unit knows that it is a priority to monitor which of the following in a client who has just undergone a stem cell transplant?

Monitor the client closely to prevent infection. Until transplanted stem cells begin to produce blood cells, these clients have no physiologic means to fight infection, which makes them very prone to infection. They are at high risk for dying from sepsis and bleeding before engraftment. Therefore, a nurse must closely monitor clients and take measures to prevent infection. Monitoring client's toilet patterns, physical condition, and heart rate does not prevent the possibility of the client getting an infection.

A patient is taking vincristine, a plant alkaloid for the treatment of cancer. What system should the nurse be sure to assess for symptoms of toxicity?

Nervous system With repeated doses, the taxanes and plant alkaloids, especially vincristine, can cause cumulative peripheral nervous system damage with sensory alterations in the feet and hands.

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

Palliative 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.

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

Progression 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.

After being seen in the oncology clinic, a client with severe bone marrow suppression is admitted to the hospital. The client's cancer therapy consisted of radiation and chemotherapy. When developing the care plan for this client, which nursing diagnosis takes priority?

Risk for infection Risk for infection takes highest priority in clients with severe bone marrow depression because they have a decrease in the number of white blood cells, the cells that fight infection. Making clients aware that they are at risk for injuries can help prevent such injuries as falls. The nurse should institute the facility's falls prevention protocol and supply assistive devices, such as a walker, cane, or wheelchair, when needed. Imbalanced nutrition: Less than body requirements is also of concern but doesn't take priority over preventing infection. Anxiety is likely present in clients with severe bone marrow depression; however, anxiety doesn't take priority over preventing infection.

A client with a brain tumor is undergoing radiation and chemotherapy for treatment of cancer. The client has recently reported swelling in the gums, tongue, and lips. Which is the most likely cause of these symptoms?

Stomatitis The symptoms of swelling in gums, tongue, and lips indicate stomatitis. This usually occurs 5 to 10 days after the administration of certain chemotherapeutic agents or radiation therapy to the head and neck. Chemotherapy and radiation produce chemical toxins that lead to the breakdown of cells in the mucosa of the epithelium, connective tissue, and blood vessels in the oral cavity.

Which oncologic emergency involves the failure in the negative feedback mechanism that normally regulates the release of antidiuretic hormone (ADH)?

Syndrome of inappropriate antidiuretic hormone release (SIADH) SIADH is a result of the failure in the negative feedback mechanism that normally regulates the release of antidiuretic hormone (ADH). Cardiac tamponade is an accumulation of fluid in the pericardial space. DIC is a complex disorder of coagulation and fibrinolysis, which results in thrombosis and bleeding. Tumor lysis syndrome is a rapidly developing oncologic emergency that results from the rapid release of intracellular contents as a result of radiation- or chemotherapy-induced cell destruction of large or rapidly growing cancers such as leukemia.

A nurse is administering daunorubicin (DaunoXome) to a patient with lung cancer. Which situation requires immediate intervention?

The I.V. site is red and swollen. A red, swollen I.V. site indicates possible infiltration. Daunorubicin is a vesicant chemotherapeutic agent and can be very damaging to tissue if it infiltrates. The nurse should immediately stop the medication, apply ice to the site, and notify the physician. Although nausea, WBC count of 1,000/mm3, and shivering require interventions, these findings aren't a high priority at this time.

Which of the following would be inconsistent as a common side effect of chemotherapy?

Weight gain Common side effects seen with chemotherapy include myelosuppression, alopecia, nausea and vomiting, anorexia, and fatigue.

A client with metastatic pancreatic cancer underwent surgery to remove a malignant tumor in the pancreas. Despite the tumor being removed, the physician informs the client that chemotherapy must be started. Why might the physician opt for chemotherapy?

To prevent metastasis Chemotherapy treats systemic and metastatic cancer. It can also be used to reduce tumor size preoperatively, or to destroy any remaining tumor cells postoperatively. Angiogenesis is the growth of new capillaries from the tissue of origin. This process helps malignant cells obtain needed nutrients and oxygen to promote growth. Fatigue and stomatitis are side effects of radiation and chemotherapy.

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?

Tumor pressure against normal tissues 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.

A client received chemotherapy 24 hours ago. Which precautions are necessary when caring for the client?

Wear personal protective equipment when handling blood, body fluids, and feces. Chemotherapy drugs are present in the waste and body fluids of clients for 48 hours after administration. The nurse should wear personal protective equipment when handling blood, body fluids, or feces. Gloves offer minimal protection against exposure. The nurse should wear a face shield, gown, and gloves when exposure to blood or body fluid is likely. Placing incontinence pads in the regular trash container and providing a urinal or bedpan don't protect the nurse caring for the client.

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

eats red meat such as steaks or hamburgers every day 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.

Cancer is the second leading cause of death in the United States, second only to heart disease. Half of all men and one third of all women will develop cancer during their lifetimes. Which types of cancer have the highest prevalence among both men and women?

lung and colon Common cancers in men include prostate, lung, and colon. Breast, lung, and colon cancer most commonly affect women.

A serum sodium concentration lower than 115 mEq/L (115 mmol/L) is associated with

seizure A serum sodium concentration lower than 115 mEq/L (115 mmol/L) is associated with seizures, abnormal reflexes, papilledema, coma, and death. Anorexia, weight gain, and myalgia are associated with serum sodium concentrations lower than 120 mEq/L.

A male client has been unable to return to work for 10 days following chemotherapy as the result of ongoing fatigue and inability to perform usual activities. Laboratory test results are WBCs 2000/mm³, RBCs 3.2 x 10¹²/L, and platelets 85,000/mm³. The nurse notes that the client is anxious. Which of the following is the priority nursing diagnosis?

Risk for infection related to inadequate defenses Physiological needs, such as risk for infection, take priority over the client's other needs.

The nurse is teaching a healthy lifestyle class to a group of adolescents. The nurse recommends

Exercising at least 60 minutes per day doing moderate to vigorous activities at least 5 days per week The American Cancer Society recommendations are for adolescents to engage in at least 60 minutes of moderate to vigorous physical activity at least 5 days per week. The MyPyramid recommendations include 4 1/2 cups of fruits and vegetables every day. People who have a body mass index less than 24 are at increased risk for problems associated with poor nutritional status. Ingesting more protein will not necessarily build more muscle mass and is not recommended for normal healthy individuals.

A patient is admitted for an excisional biopsy of a breast lesion. What intervention should the nurse provide for the care of this patient?

Provide time for the patient to discuss her concerns. Patients who are undergoing surgery for the diagnosis or treatment of cancer may be anxious about the surgical procedure, possible findings, postoperative limitations, changes in normal body functions, and prognosis. The patient and family require time and assistance to process the possible changes and outcomes resulting from the surgery. The nurse serves as the patient advocate and liaison and encourages the patient and family to take an active role in decision making when possible. If the patient or family asks about the results of diagnostic testing and surgical procedures, the nurse's response is guided by the information that was conveyed previously. The nurse may be asked to explain and clarify information for patients and families that was provided initially but was not grasped because of anxiety and overwhelming feelings. It is important that the nurse, as well as other members of the health care team, provide information that is consistent from one clinician to another.

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.

-Cigarette smoking -Age -Occupation 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.

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?

Excisional biopsy 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.
