Cancer (Pellico 6)
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.
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.
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
5-Fluorouracil (5FU) is classified as which type of antineoplastic agent?
Antimetabolite
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.
Following a bone marrow transplantation (BMT), the patient should be monitored for at least:
3 months After a BMT, the nurse closely monitors the patient for at least 3 months because complications related to the transplant are still possible, and infections are very common.
Following surgery for adenocarcinoma, the client learns the tumor stage is T3,N1,M0. What treatment mode will the nurse anticipate?
Adjuvant therapy is likely. T3 indicates a large tumor size with N1 indicating regional lymph node involvement. 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.
Which oncologic emergency involves the accumulation of fluid in the pericardial space?
Cardiac tamponade.
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 client is receiving a vesicant antineoplastic for treatment of cancer. Which assessment finding would require the nurse to take immediate action?
Extravasation Leakage of medication from the veins into the subcutaneous tissues.
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.
When the client complains of increased fatigue following radiotherapy, the nurse knows this is most likely to be related to which factor?
Radiation can result in myelosuppression. Fatigue results from anemia associated with myelosuppression and decreased RBC production
Which of the following is a term used to describe the process by which a new blood supply is formed?
Angiogenesis
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 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.
The nurse is caring for a client who has had a nuclear scan to aid in the diagnosis of possible cancer. The scan showed a "hot spot". What does this mean?
An area of increased concentrations of the tracer used in the scan. Nuclear Scans: Clients ingest or receive intravenous (IV) radioisotopes (also known as tracers). After specific time intervals, images are taken of tissues that are affected by cancer or other diseases; the images distinguish tissues or portions of tissues that absorb more or less of the tracer. "Hot spots" show on an image of a tumor that has increased concentrations of the tracer, whereas "cold spots" can be the image of a tumor that has decreased concentration of the tracer. Options B, C, and D are incorrect information about hot spots.
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.
