ATI Oncology Quiz

1. 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.

2. An older adult patient is undergoing diagnostic testing for chronic lymphocytic leukemia (CLL). What assessment finding is certain to be present if the patient has CLL?

Correct answer: B

Rationale: An increased lymphocyte count (lymphocytosis) is always present in patients with CLL.

3. The patient is anxious about subjection to radiation therapy. Which of the following statements of the student nurse requires additional teaching?

Correct answer: D

Rationale: The correct answer is D because the statement 'Chemotherapy is effective in killing all cancer cells' is incorrect. Chemotherapy does not kill all cancer cells and is not the same as radiation therapy. Chemotherapy targets rapidly dividing cells, including cancer cells, but it may not kill every single cancer cell. It is important for the student nurse to understand and communicate this distinction to the patient. Choices A, B, and C provide accurate information about teletherapy, brachytherapy, and chemotherapy, respectively, and do not require additional teaching.

4. The nurse is teaching a client about the signs of infection after chemotherapy. Which of the following should the nurse emphasize?

Correct answer: D

Rationale: In clients undergoing chemotherapy, the immune system is often compromised due to the effects of treatment, making them more susceptible to infections. A fever over 100.4°F (38°C) is considered a critical sign of infection in these patients and requires immediate medical evaluation. Fever may indicate the presence of an infection that could escalate quickly in immunocompromised individuals, so it is vital for patients to recognize this symptom and seek prompt medical attention.

5. Following an extensive diagnostic workup, an older adult patient has been diagnosed with a secondary myelodysplastic syndrome (MDS). What assessment question most directly addresses the potential etiology of this patient's health problem?

Correct answer: A

Rationale: The correct answer is A. Secondary MDS can occur at any age and results from prior toxic exposure to chemicals, including chemotherapeutic medications. Asking about exposure to toxic chemicals in previous jobs directly addresses the potential etiology of this patient's health problem. Choices B, C, and D are not as directly related to the etiology of secondary MDS. Recurrent infections (Choice B) are not a known cause of MDS. Family history (Choice C) is more pertinent to primary MDS, which has a genetic component, while sun exposure (Choice D) is not associated with the etiology of MDS.
