Question 1

A patient has just been diagnosed with cancer and will begin chemotherapy. The patient asks the nurse about the possibility of nausea and vomiting. The nurse will tell the patient that:&#10;A) nausea and vomiting can be avoided by having a snack before chemotherapy.&#10;B) nausea and vomiting are common side effects and will abate over time.&#10;C) nausea and vomiting are common and will be treated with antiemetics when they occur.&#10;D) the provider will order drugs to help prevent nausea and vomiting before each dose.

Accepted Answer

Nausea and vomiting are common but can be reduced by premedication with antiemetics. Having a snack before dosing is not effective. This side effect will not abate over time. Antiemetics are most effective when given before dosing,not as needed.

Question 2

The nurse wants to evaluate a nursing student's understanding of chemotherapy. The nurse asks,&#34;Which factor would be a major obstacle to successful chemotherapy?&#34; What is the student's best response?&#10;A) &#34;The patient's reluctance about the doses administered.&#34;&#10;B) &#34;The patient's degree of nausea.&#34;&#10;C) &#34;The toxicity of anticancer drugs to normal tissues.&#34;&#10;D) &#34;The difficulty attaining and maintaining venous access.&#34;

Accepted Answer

The major obstacle to successful chemotherapy is the toxicity of anticancer drugs to normal tissues. The patient's reluctance regarding the dose is a vague response. The patient's degree of nausea should not be an issue,because many good antiemetics may be given prophylactically. The question does not address whether the chemotherapy is administered PO or IV; therefore,the response regarding venous access would be an assumption.

Question 3

These patients are receiving chemotherapy. Which patient should the nurse see first?&#10;A) The patient with lightly bleeding gums&#10;B) The patient with nausea and vomiting&#10;C) The patient with a fever of 100.3&#176;F&#10;D) The patient with diarrhea and stomatitis

Accepted Answer

Fever is the principal early sign of infection,which can have extremely serious implications for an immunosuppressed patient. Because of a lack of neutrophils as a result of chemotherapy,signs of infection may be masked. Lightly bleeding gums,nausea,and vomiting are to be expected in patients receiving chemotherapy. Diarrhea and stomatitis also are common in patients receiving chemotherapy.

Question 4

A hospitalized patient with cancer is receiving chemotherapy and reports oral pain. Inspection of this patient's oral mucosa reveals erythema and inflammation without denudation or ulceration. The nurse understands that:

A) chemotherapy will have to be stopped until healing of the oral mucosa occurs.
B) the patient can use a mouthwash with a topical anesthetic to control pain.
C) the patient will need an antifungal agent to treat Candida albicans.
D) the patient will need systemic opioids to control discomfort.

Accepted Answer

Patients with mild stomatitis can use a mouthwash with a local anesthetic to control pain. Chemotherapy does not have to be stopped until the pain or ulceration is severe. Antifungal agents may be used to treat Candida albicans; this patient does not exhibit signs of that infection. Systemic opioids may be used when pain becomes severe.

Question 5

A patient with cancer who is receiving chemotherapy develops a fever. The patient's chest radiograph is normal. The patient's neutrophil count is 750/mm&#179;. The nurse expects the provider to:&#10;A) begin empiric therapy with intravenous antibiotics.&#10;B) obtain cultures and wait for results before prescribing antibiotics.&#10;C) order colony-stimulating factor to minimize neutrophilia.&#10;D) reassure the patient that serious infection is unlikely.

Accepted Answer

In the absence of neutrophils,as occurs with bone marrow suppression in chemotherapy,fever is the principle sign of infection. Pus,abscesses,and infiltrates on a chest x-ray may all be absent. When a neutropenic patient develops an infection,immediate and vigorous intervention is required. Empiric IV antibiotic therapy should begin while waiting for laboratory results and cultures. It is not correct to wait for culture results before initiating antibiotic therapy. Colony-stimulating factor can minimize neutropenia but does not eliminate the need for IV antibiotics. It is not correct to reassure the patient that a serious infection is unlikely.

Question 6

A patient who has undergone surgical removal of a solid tumor has just begun chemotherapy. The patient experiences severe nausea and vomiting as well as alopecia. The nurse will expect the provider to:

A) continue the chemotherapeutic agent at the same dose.
B) decrease the dose of chemotherapy to minimize side effects.
C) order lab tests to evaluate for the presence of residual cancer cells.
D) stop the chemotherapy because the tumor has been removed.

Accepted Answer

Cure of cancer requires 100% cell kill. Solid tumors,which often respond poorly to chemotherapeutic agents,can be "debulked" with surgery and then treated with cytotoxic drugs,because the remaining cells often re-enter the cell cycle and become sensitive to the drugs. Chemotherapeutic drugs must be given at the same dose throughout therapy because of the kinetics of drug-induced cell kill. Because chemotherapy has just begun,it is still necessary; moreover,cell counts of fewer than 1 billion cells are no longer detectable and treatment must continue until all cells are eradicated,so lab tests will not yield useful information. Stopping the chemotherapy right after surgery is not indicated.

Question 7

A nurse explains to a patient with cancer why it is difficult to achieve 100% cell kill to cure cancer with chemotherapy. Which statement by the patient indicates a need for further teaching?&#10;A) &#34;It is necessary to continue giving the same dose of chemotherapeutic agents throughout therapy, even if toxicity occurs.&#34;&#10;B) &#34;Symptoms of cancer often disappear before all malignant cells are eradicated.&#34;&#10;C) &#34;The immune system attacks chemotherapeutic agents and renders them impotent.&#34;&#10;D) &#34;The immune system often fails to recognize cancer cells as foreign.&#34;

Accepted Answer

The immune system does not attack chemotherapeutic agents,so this statement would indicate a need for further teaching. The same dose of chemotherapeutic agents must be given throughout therapy,which becomes difficult when patients have severe toxic reactions. Because cancer symptoms often disappear before all cells are killed,some therapies are stopped prematurely. The immune system does not recognize cancer cells as foreign and thus does not assist in cell kill.

Question 8

A nursing student asks a nurse why chemotherapeutic agents are given intermittently instead of continuously. The nurse will tell the student that intermittent dosing:&#10;A) allows normal cells to recover and repopulate.&#10;B) catches malignant cells in latent phases.&#10;C) increases cancer cell kill and speeds up treatment.&#10;D) suppresses drug resistance in tumor cells.

Accepted Answer

Intermittent chemotherapy allows normal cells to repopulate between rounds of therapy. Cells in latent phases do not generally respond to chemotherapy. Intermittent therapy does not speed up treatment or increase tumor cell kill. Intermittent therapy does not suppress drug resistance in tumor cells.

Question 9

A patient who has leukemia is receiving chemotherapy and develops severe anemia. The provider has ordered hospitalization and blood transfusions. The patient asks the nurse about using erythropoietin (epoetin alfa)instead. What will the nurse tell this patient?

A) "Ask your provider about ordering erythropoietin instead of a transfusion."
B) "Erythropoietin (epoetin alfa) can make your leukemia worse."
C) "Erythropoietin is used to prolong life in patients with myeloid malignancies."
D) "You will probably receive erythropoietin along with the transfusion."

Accepted Answer

Erythropoietin is used to stimulate erythrocyte production but can also stimulate proliferation of cancers in patients with leukemia and other myeloid malignancies. It is used when the goal is palliation,not to cure or to prolong life.

Question 10

Which are guidelines for selecting chemotherapeutic agents to use in combination therapy? (Select all that apply.)&#10;A) Drugs used should have different mechanisms.&#10;B) Each drug should be delivered by different routes.&#10;C) Each drug should be effective.&#10;D) Each drug should have different dosing schedules.&#10;E) Toxicities should be minimally overlapping.

Accepted Answer

When selecting drugs for combination therapy,each drug should be effective by itself and should have a different mechanism of action. The drugs should have minimally overlapping toxicities. The routes and the dosing schedules are not considerations.
