Prep U: Chpt. 12 Oncologic Disorders
While administering an intravenous chemotherapeutic medication 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 must immediately stop 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.
The nurse understands that the client should be given human papillomavirus (HPV) vaccine per the health care provider's orders. What does this vaccine help prevent?
cervical cancer The vaccines that are approved for use in the United States include the human papillomavirus (HPV), which may help prevent women from getting cervical cancer. There are no vaccines for the prevention of lung cancer, breast cancer, or leukemia.
The nurse is caring for a client with a benign breast tumor. The tumor may have which characteristic?
Slow rate of growth Benign tumors have a slow rate of growth and well-differentiated cells. Benign tumors do not invade surrounding tissue and do not cause generalized symptoms unless the location of the tumor interferes with the functioning of vital organs.
A nurse is caring for a client receiving chemotherapy. Which assessment finding places the client at the greatest risk for an infection?
Stage 3 pressure ulcer on the left heel A stage 3 pressure ulcer is a break in the skin's protective barrier, which could lead to infection in a client who is receiving chemotherapy. The WBC count and temperature are within normal limits. Eating 75% of meals is normal and doesn't increase the client's risk for infection. A client who is malnourished is at a greater risk for 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.
An oncology nurse is caring for a client who relates that certain tastes have changed. The client states that "meat tastes bad." What nursing intervention can be used to increase protein intake for a client with taste changes?
Encourage eating cheese, eggs, and legumes The nurse encourages the clients with taste changes to eat cheese, eggs, and legumes. Encouraging the client to take in the maximum amount of fluids does not increase protein intake. The nurse advises the client to drink protein beverages. Sucking on hard candies during treatment does not increase protein intake.
You are a clinic nurse. One of your clients has found she is at high risk for breast cancer. She asks you what can be done to reduce her risk. What is a means of reducing the risk for breast cancer?
Prophylactic surgery Prophylactic or preventive surgery may be done if the client is at considerable risk for cancer. Palliative surgery is done when no curative treatment is available. Curative surgery is performed to cure the disease process. Reduction surgery is a distractor.
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.
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 vaccine uses the client's own cancer cells, which are killed and prepared for injection back into the client?
Autologous Autologous vaccines are made from the client's own cancer cells, which are obtained during diagnostic biopsy or surgery. Prophylactic vaccines, such as the polio vaccine, are given to prevent people from developing a disease. Therapeutic vaccines are given to kill existing cancer cells and to provide long-lasting immunity against further cancer development. Allogeneic vaccines are made from cancer cells that are obtained from other people who have a specific type of cancer.
A nurse is teaching a client with bone marrow suppression about the time frame when bone suppression will be noticeable after administration of floxuridine. What is the time frame the nurse should include with client teaching?
7 to 14 days Bone marrow suppression becomes noticeable 7 to 14 days after floxuridine administration. Bone marrow recovery occurs in 21 to 28 days.
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.
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.
The clinic nurse is caring for a 42-year-old client who reports extreme fatigue and weakness after the first week of radiation therapy. Which response by the nurse would best reassure this client?
"These symptoms are commonly associated with radiation therapy. We'll discuss some strategies to minimize and cope with fatigue." Fatigue is a common symptom in patients with cancer and is nearly universal in those receiving cytotoxic chemotherapy, radiation therapy, bone marrow transplantation, or treatment with biologic response modifiers. The nurse should help the patient and family understand that fatigue is an expected side effect of cancer and cancer treatment, while also providing nursing strategies to help them cope. The symptoms may concern the client and should not be belittled. Fatigue may also be exacerbated by other factors such as the stress of coping with cancer. It does not necessarily signify the success or failure of the treatment, and it would be inappropriate for the nurse to definitively tell the client that the treatment is working.
A nurse is planning caring for a client who has developed erythema following radiation therapy for a lesion on the left lower leg. Which intervention would the nurse include in the client's plan of care to best support skin recovery at the affected site?
Cleanse with lukewarm water and pat dry Erythema is a term used to describe redness of body tissue. Care to the affected area must focus on preventing further skin irritation, drying, and damage; the client should cleanse the area with lukewarm water and mild, nondeodorant soap, and pat dry. Application of ice, shaving, and wearing tight fitting clothing over the area could further damage the already traumatized tissue. Emollients may be used as directed by the radiation oncologist to soothe and moisturize irritated skin. However, even approved emollients should not be used up to 4 hours before the treatment time.
For a client newly diagnosed with radiation-induced thrombocytopenia, the nurse should include which intervention in the care plan?
Inspecting the skin for petechiae once every shift 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?
It lowers serum and uric acid levels. 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.
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.
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.
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. dietary substances environmental factors viruses gender age
dietary substances environmental factors viruses 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 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
The nurse is working with a client who has had an allo-hematopoietic stem cell transplant (HSCT). The nurse notices a diffuse rash and diarrhea. The nurse contacts the physician to report that the client has symptoms of
graft-versus-host disease. Graft-versus-host disease is a major cause of morbidity and mortality in clients who have had allogeneic transplant. Clinical manifestations of the disease include diffuse rash that progresses to blistering and desquamation, and mucosal inflammation of the eyes and the entire gastrointestinal tract with subsequent diarrhea, abdominal pain, and hepatomegaly.
A decrease in circulating white blood cells (WBCs) is referred to as
leukopenia A decrease in circulating WBCs is referred to as leukopenia. Granulocytopenia is a decrease in neutrophils. Thrombocytopenia is a decrease in the number of platelets. Neutropenia is an abnormally low absolute neutrophil count.
A client with cancer is being evaluated for possible metastasis. What is one of the most common metastasis sites for cancer cells?
liver The liver is one of the five most common cancer metastasis sites. The others are the lymph nodes, lung, bone, and brain. The colon, reproductive tract, and WBCs are occasional metastasis sites.
Which is a sign or symptom of septic shock?
altered mental status Signs of septic shock include altered mental status, cool and clammy skin, decreased urine output, and hypotension.
An oncologist advises a client with an extensive family history of breast cancer to consider a mastectomy. What type of surgery would the nurse include in teaching?
prophylactic Also called preventive surgery, prophylactic surgery may be done when there is a family history or genetic predisposition, ability to detect cancer at an early stage, and client acceptance of the postoperative outcome. Local excision is done when an existing tumor is removed along with a small margin of healthy tissue. Palliative surgery relieves symptoms. Cryosurgery uses cold to destroy cancerous cells.
A nurse is caring for a client newly diagnosed with cancer. Which therapies are used to treat cancer? Select all that apply. surgery hyperthermia radiation therapy chemotherapy electroconvulsive therapy
surgery hyperthermia radiation therapy chemotherapy Cancer is frequently treated with a combination of therapies using standardized protocols. The basic methods used to treat cancer are surgery, radiation therapy, hyperthermia, and chemotherapy. Electroconvulsive therapy is a method of treatment for mental distress or illness.
A 36-year-old man is receiving three different chemotherapeutic agents for Hodgkin's disease. The nurse explains to the client that the three drugs are given over an extended period because:
The three drugs have a synergistic effect and act on the cancer cells with different mechanisms. Multiple drug regimens are used because the drugs have a synergistic effect. The drugs have different cell-cycle lysis effects, different mechanisms of action, and different toxic adverse effects. They are usually given in combination to enhance therapy. Dosage is not affected by giving the drugs in combination. The second and third drugs do not increase the effectiveness of the first. It is not true that the first two drugs are toxic to cancer cells while the third drug promotes cell growth.
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?
"I hope they find a bone marrow donor who matches." 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.
The nurse instructs a client receiving chemotherapy on actions to prevent the development of stomatitis. Which client statement indicates to the nurse that teaching has been effective?
"I will brush my teeth after every meal." Stomatitis is an inflammatory process of the mouth, including the mucosa and tissues surrounding the teeth. Manifestations of stomatitis include changes in sensation, erythema, and edema, or if severe, painful ulcerations, bleeding, and infection. It commonly develops within 3 to 14 days after receiving certain chemotherapeutic agents. Actions to prevent the development of stomatitis include brushing the teeth with a soft toothbrush for 90 seconds after every meal. Smoking dries oral tissues and should be avoided. Spicy foods can irritate the oral tissues and should be avoided. Alcohol is drying to the oral tissues and should be avoided.
Which does a nurse thoroughly evaluate before a hematopoietic stem cell transplant (HSCT) procedure?
Blood studies Before the HSCT procedure, the nurse thoroughly evaluates the client's physical condition; organ function; nutritional status; complete blood studies, including assessment for past exposure to antigens such as HIV, hepatitis, or cytomegalovirus; and psychosocial status. Before an HSCT procedure, the nurse need not evaluate client's family, drug, or allergy history.
A patient with uterine cancer is being treated with internal radiation therapy. What would the nurse's priority responsibility be for this patient?
Explain to the patient that she will continue to emit radiation while the implant is in place. When the patient has a radioactive implant in place, the nurse and other health care providers need to protect themselves, as well as the patient, from the effects of radiation. Patients receiving internal radiation emit radiation while the implant is in place; therefore, contact with the health care team is guided by principles of time, distance, and shielding to minimize exposure of personnel to radiation. Safety precautions used in caring for a patient receiving brachytherapy include assigning the patient to a private room, posting appropriate notices about radiation safety precautions, having staff members wear dosimeter badges, making sure that pregnant staff members are not assigned to the patient's care, prohibiting visits by children or pregnant visitors, limiting visits from others to 30 minutes daily, and seeing that visitors maintain a 6-foot distance from the radiation source.
What intervention should the nurse provide to reduce the incidence of renal damage when a patient is taking a chemotherapy regimen?
Encourage fluid intake to dilute the urine. The nurse should ensure adequate fluid hydration before, during, and after drug administration and assess intake and output. Adequate fluid volume dilutes drug levels, which can help prevent renal damage.
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.
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 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.
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.
According to the tumor-node-metastasis (TNM) classification system, T0 means there is
No evidence of primary tumor T0 means that there is no evidence of primary tumor. N0 means that there is no regional lymph node metastasis. M0 means that there is no distant metastasis. M1 means that there is distant metastasis.
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.
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.
