Ch 15: Management of Patients with Oncologic Disorders (2)

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.

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? pg. 364

Encourage eating cheese, eggs, and legumes Explanation: 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.

The physician is attending to a 72-year-old client with a malignant brain tumor. The physician recommends immediate radiation therapy. What is a reason for the physician's recommendation?

To prevent the formation of new cancer cells Explanation: Radiation therapy helps prevent cellular growth. It may be used to cure the cancer or to control malignancy when the tumor cannot be removed or when lymph node involvement is present; also, it can be used prophylactically to prevent spread. Biopsy is used to analyze lymph nodes or to destroy the surrounding tissues around the tumor.

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 pg. 375

"You will need to practice birth control measures." Explanation: 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 nurse is preparing to assess a client whose chart documents that the client experienced extravasation when receiving the vesicant vincristine during the previous shift. The documentation also notes that an antidote was administered immediately. The nurse prepares to assess for which conditions? Select all that apply.

- Sloughing tissue - Tissue necrosis - Effectiveness of the antidote Explanation: Extravasation of vesicant chemotherapeutic agents can lead to erythema, sloughing, and necrosis of surrounding tissue, muscle, and tendons. To reduce the likelihood and severity of symptoms due to extravasation of a vesicant, antidotes matched to the vesicant are administered. Nurses caring for a client who experienced extravasation of a vesicant should assess for sloughing tissue, tissue necrosis, erythema, and effectiveness of the antidote.

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? pg. 329

An aunt and uncle diagnosed with cancer Explanation: 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.

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.

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? pg. 335

Carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis Explanation: 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.

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.

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.

A client is scheduled for a nerve-sparing prostatectomy. The emotional spouse confides in the nurse that the client will not talk about the cancer and/or upcoming surgery. Which nursing diagnosis will the nurse choose as primary diagnosis for this client? pg. 375

Fear Explanation: Fear of the unknown is probably the major concern for this client. This includes fear of the diagnosis of cancer, fear of the effects of the surgery, and fear of loss of control and functioning. Sexual Dysfunction may be one of the fears but not primary at this stage. Knowledge Deficit is unclear at this time. Grieving would not be a likely response at this time.

When caring for an older client who is receiving external beam radiation, which is the key point for the nurse to incorporate into the plan of care? pg. 340

Inspect the skin frequently. Explanation: Inspecting the skin frequently will allow early identification and intervention of skin problems associated with external radiation therapy. The external markings should not be removed, but clients may shower and lightly wash over the skin. Time, distance, and shielding are key in the management of sealed, internal radiation therapy and not external beam radiation. The use of disposable utensils and care items would be important when caring for clients following systemic, unsealed, internal radiation therapy.

A decrease in circulating white blood cells (WBCs) is referred to as

Leukopenia Explanation: 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.

In which phase of the cell cycle does cell division occur? pg. 341

Mitosis Explanation: 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.

A nurse is caring for a client after a bone marrow transplant. What is the nurse's priority in caring for the client? pg. 350

Monitor the client to prevent sepsis. Explanation: Until transplanted bone marrow begins to produce blood cells, clients who have undergone a bone marrow transplant have no physiologic means to fight infection, which puts them at high risk for dying from sepsis and bleeding before engraftment. Therefore, a nurse must closely monitor clients and take measures to prevent sepsis. Monitoring client's toilet patterns, physical condition, and heart rate does not prevent the possibility of the client becoming septic.

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.

A nurse is receiving a client with a radioactive implant for the treatment of cervical cancer. What is the nurse's best action? pg. 341

Place the client in a private room. Explanation: Safety precautions are used for the client with a radioactive implant. They include assigning the client to a private room, seeing that visitors maintain a 6-foot distance from the radiation source, prohibiting visits by children, and preventing exposure to those who may be or are pregnant. Staff needs to wear dosimeters. Family may visit for up to 30 minutes per day.

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.

A client is receiving chemotherapy to treat breast cancer. Which assessment finding indicates a chemotherapy-induced complication? pg. 383

Serum potassium level of 2.6 mEq/L Explanation: Chemotherapy commonly causes nausea and vomiting, which may lead to fluid and electrolyte imbalances. Signs of fluid loss include a serum potassium level below 3.5 mEq/L, decreased urine output (less than 40 ml/hour), and abnormally low blood pressure. Urine output of 400 ml in 8 hours, serum sodium level of 142 mEq/L, and a blood pressure of 120/64 to 130/72 mm Hg aren't abnormal findings.

A nurse is caring for a client receiving chemotherapy. Which assessment finding places the client at the greatest risk for an infection? pg. 345

Stage 3 pressure ulcer on the left heel Explanation: 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.
