Oncology Questions
1. Which of the following is not a manifestation of breast cancer?
- A. Peau d'orange
- B. Painless breast mass
- C. Alopecia
- D. Breast enlargement
Correct answer: C
Rationale: Alopecia (hair loss) is not a direct manifestation of breast cancer but rather a common side effect of chemotherapy used in breast cancer treatment. Peau d'orange refers to the dimpling or pitting of the skin resembling an orange peel, which can be a sign of breast cancer due to blockage of lymphatic vessels. A painless breast mass and breast enlargement can both be manifestations of breast cancer, with a painless mass being a common symptom and breast enlargement sometimes occurring due to tumor growth.
2. A patient with myelofibrosis is being treated with ruxolitinib. What should the nurse monitor to assess the effectiveness of this treatment?
- A. Blood pressure
- B. White blood cell count
- C. Hemoglobin and hematocrit
- D. Spleen size
Correct answer: C
Rationale: Monitoring hemoglobin and hematocrit is essential to assess the effectiveness of ruxolitinib in treating myelofibrosis. Ruxolitinib works by inhibiting JAK1 and JAK2, which are involved in the signaling pathways that regulate blood cell production. Therefore, monitoring hemoglobin and hematocrit levels can provide valuable information on how well the drug is managing the disease. Blood pressure, white blood cell count, and spleen size are not direct indicators of the treatment's effectiveness in myelofibrosis.
3. The nurse is monitoring a client for signs and symptoms related to superior vena cava syndrome. Which is an early sign of this oncological emergency?
- A. Cyanosis
- B. Arm edema
- C. Periorbital edema
- D. Mental status changes
Correct answer: C
Rationale: Superior vena cava syndrome (SVCS) occurs when the superior vena cava, the large vein that carries blood from the upper body to the heart, becomes compressed or obstructed, often by a tumor or enlarged lymph nodes, typically in cancers like lung cancer or lymphoma. The obstruction leads to increased venous pressure and reduced blood flow, resulting in swelling and edema in areas drained by the superior vena cava. Periorbital edema (swelling around the eyes) is one of the earliest signs of SVCS. This occurs because the impaired venous return causes fluid to accumulate in the soft tissues of the face, especially around the eyes. As the condition progresses, facial swelling can worsen, and other symptoms develop.
4. An emergency department nurse is triaging a 77-year-old man who presents with uncharacteristic fatigue as well as back and rib pain. The patient denies any recent injuries. The nurse should recognize the need for this patient to be assessed for what health problem?
- A. Hodgkin disease
- B. Non-Hodgkin lymphoma
- C. Multiple myeloma
- D. Acute thrombocythemia
Correct answer: C
Rationale: The correct answer is multiple myeloma (choice C). Back pain is a common presenting symptom in multiple myeloma, especially in older patients. This malignancy can lead to bone pain due to bone destruction and fractures. Hodgkin disease (choice A) and Non-Hodgkin lymphoma (choice B) typically present with symptoms like painless lymph node enlargement, fever, and weight loss. Acute thrombocythemia (choice D) is characterized by an increase in platelet count but is not typically associated with the symptoms described by the patient.
5. The cells of a normal individual can replicate in a specified rate. If the rate of replication becomes uncontrollable, which of the following is lacking from the patient?
- A. Apoptosis
- B. Contact inhibition
- C. Stable cells
- D. Labile cells
Correct answer: B
Rationale: Contact inhibition is a regulatory mechanism that prevents cells from proliferating once they reach a certain density. Normally, when cells grow and touch each other (such as in a monolayer), they stop dividing, maintaining tissue integrity and structure. When contact inhibition is lacking, as in many cancerous cells, cells continue to grow and divide uncontrollably, leading to tumor formation. This loss of regulation is a hallmark of cancerous growth.
