Oncology Questions

1. Which of the following is a correct statement by the nurse to a patient under radiation therapy?

Correct answer: C

Rationale: The correct answer is C: 'Brachytherapy is an internal radiation therapy.' Brachytherapy involves the placement of radioactive sources inside or next to the area requiring treatment. This differs from teletherapy, which is external radiation therapy. Choice A is incorrect as pregnant individuals should avoid exposure to radiation. Choice B is incorrect because teletherapy does not make the patient radioactive; the radiation source is external. Choice D is incorrect as feces is not a significant source of radiation during teletherapy.

2. A client with long-standing heart failure being treated for cancer has received a dose of ondansetron for nausea. What action by the nurse is most important?

Correct answer: B

Rationale: Ondansetron can prolong the QT interval, making cardiac monitoring essential in this scenario.

3. A nurse works on an oncology unit and delegates personal hygiene to assistive personnel (AP). What action by the AP requires intervention from the nurse?

Correct answer: A

Rationale: Skipping oral hygiene is not appropriate for a client, even if they are tired, as it increases the risk of infection.

4. The nurse is caring for a patient who is to begin receiving external radiation for a malignant tumor of the neck. While providing patient education, what potential adverse effects should the nurse discuss with the patient?

Correct answer: A

Rationale: Corrected Rationale: Impaired nutritional status is a potential adverse effect of radiotherapy to the head and neck due to alterations in oral mucosa and taste. While cognitive changes, diarrhea, and alopecia can be side effects of other treatments or conditions, they are not typically associated with external radiation for a malignant tumor of the neck. Therefore, the nurse should primarily focus on discussing the risk of impaired nutritional status with the patient.

5. A client is diagnosed as having a positive reaction to the Mantoux test. Which of the following is the most appropriate nursing action?

Correct answer: C

Rationale: The correct answer is to schedule the client for a chest x-ray. A positive Mantoux test indicates exposure to TB, but it does not confirm active disease. A chest x-ray is necessary to assess the presence of active TB disease. Isolating the client in a private room (Choice A) is not necessary based solely on a positive Mantoux test result. Administering isoniazid (INH) (Choice B) or beginning a 9-month course of medication therapy (Choice D) is premature without confirming active TB through a chest x-ray.
