A patient diagnosed with polycythemia vera presents to the clinic for routine bloodwork. What should the nurse monitor for in this patient as a priority?
- A. Hemoglobin and hematocrit levels
- B. Platelet count
- C. White blood cell count
- D. Blood pressure
Correct Answer: B
Rationale: In polycythemia vera, there is an overproduction of red blood cells, white blood cells, and platelets, which leads to increased blood viscosity and a high risk for thrombosis (blood clot formation). Monitoring the platelet count is a priority because elevated platelet levels contribute significantly to the risk of developing blood clots, which can result in life-threatening complications such as strokes, heart attacks, or deep vein thrombosis (DVT). Therefore, regular monitoring of the platelet count is essential to assess the patient's risk for thrombosis and to guide treatment decisions, such as phlebotomy or medication adjustments to lower platelet levels.

Which of the following statements by the oncology nurse displays understanding about antineoplastic medications?
- A. Chemotherapy is not going to spread throughout the body
- B. Chemotherapy affects the immune system
- C. Chemotherapy is specific to cancer cells only
- D. Chemotherapy makes the patient radioactive
Correct Answer: B
Rationale: Chemotherapy targets rapidly dividing cells, which include both cancerous and healthy cells, such as those in the bone marrow, hair follicles, and the lining of the digestive tract. Since the bone marrow produces immune cells (white blood cells), chemotherapy can weaken the immune system by reducing the body's ability to produce these cells, making patients more susceptible to infections. This is why close monitoring and supportive measures to protect immune function are important during chemotherapy treatment.
A nurse is caring for a client admitted for Non-Hodgkin's lymphoma and chemotherapy. The client reports nausea, flank pain, and muscle cramps. What action by the nurse is most important?
- A. Request an order for serum electrolytes and uric acid.
- B. Increase the client's IV infusion rate.
- C. Instruct assistive personnel to strain all urine.
- D. Administer an IV antiemetic.
Correct Answer: A
Rationale: The client's symptoms of nausea, flank pain, and muscle cramps are suggestive of tumor lysis syndrome (TLS), a potentially life-threatening complication of chemotherapy in which cancer cells break down rapidly, releasing large amounts of intracellular components into the bloodstream. This leads to imbalances in electrolytes (elevated potassium, phosphate, and uric acid levels, with low calcium levels), which can cause severe metabolic disturbances, including kidney damage, arrhythmias, and muscle cramps. Checking serum electrolytes and uric acid levels is crucial for diagnosing and managing TLS early, preventing further complications.
A nurse is caring for a patient with myelodysplastic syndrome (MDS) who is receiving erythropoietin therapy. What should the nurse monitor to evaluate the effectiveness of this treatment?
- A. Platelet count
- B. Hemoglobin level
- C. White blood cell count
- D. Oxygen saturation
Correct Answer: B
Rationale: Erythropoietin therapy is used to stimulate the production of red blood cells in patients with myelodysplastic syndrome (MDS), a disorder characterized by ineffective blood cell production, including red blood cells. The primary goal of erythropoietin therapy is to increase red blood cell count, improving the patient's oxygen-carrying capacity and reducing symptoms of anemia, such as fatigue and weakness. Monitoring hemoglobin levels is the best way to evaluate the effectiveness of this therapy because it directly reflects the patient's red blood cell count and the success of erythropoiesis (red blood cell production).
The nurse is assessing the colostomy of a client who has had an abdominal perineal resection for a bowel tumor. Which assessment finding indicates that the colostomy is beginning to function?
- A. The passage of flatus
- B. Absent bowel sounds
- C. The client¢â‚¬â„¢s ability to tolerate food
- D. Bloody drainage from the colostomy
Correct Answer: A
Rationale: The passage of flatus (gas) from the colostomy is an early sign that the bowel is beginning to function after surgery. This indicates that peristalsis, or the movement of the intestines, has resumed and that the digestive system is actively moving gas and eventually stool through the bowel and out of the colostomy. It's a positive sign that the bowel is recovering from the surgery and starting to work as intended.
The nurse knows that all of the following are risk factors for breast cancer except:
- A. Family history
- B. Nulliparity
- C. Chest xray
- D. Multiple sex partners
Correct Answer: D
Rationale: Multiple sex partners are not a recognized risk factor for breast cancer. Breast cancer is primarily influenced by hormonal, genetic, and environmental factors, not sexual activity or the number of sexual partners. Established risk factors for breast cancer include family history, hormonal factors such as early menarche, late menopause, and nulliparity (having no children), as well as certain environmental exposures.
