A patient, diagnosed with lymphoma, has an allergy to one of the proposed chemotherapy drugs. The tumor has not responded to other types of treatment. The nurse expects the oncologist to follow which course of treatment?
- A. The physician will choose another drug to use.
- B. The chemotherapy will be given along with supportive measures to treat a possible allergic reaction.
- C. The patient will receive reduced doses of chemotherapy for a longer period of time.
- D. The chemotherapy cannot be given because of the patient's allergy.
Correct Answer: B
Rationale: Even if a patient has a known allergic reaction to a given antineoplastic medication, the urgency of treating the patient's cancer may still necessitate administering the medication and then treating any allergic symptoms with supportive medications, such as antihistamines, corticosteroids, and acetaminophen.
The nurse is about to administer vincristine to a patient who has brain cancer. The patient has an intravenous port and an epidural line for pain medication. Which of these actions would the nurse question?
- A. Administer the vincristine via the intravenous line.
- B. Administer the vincristine via the intrathecal line (spinal route).
- C. Use an infusion pump for this medication.
- D. Give the vincristine with another chemotherapeutic agent.
Correct Answer: B
Rationale: Vincristine and other vinca alkaloids are not given intrathecally (via the spinal route) or by any other route except intravenously. Administering these drugs through the spinal route is almost always fatal, and the death is slow and excruciating. The error cannot be reversed once the medication is given. These drugs are often given in combination with other chemotherapeutic agents, and an infusion pump must be used for accurate delivery of medication.

Correct Answer: A
Rationale: Sarcomas are malignant tumors that arise from connective tissues. These tissues can be found in bone, cartilage, muscle, blood, lymphatic, and vascular tissues. The other options are incorrect.

- B. The aspirin will mask signs of infection.
- C. Aspirin can lead to methotrexate toxicity.
- D. The aspirin will cause no problems for the patient on methotrexate.
