Nursing Elites

1. 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.

2. Nurse Mike is providing care to a client with chronic myelogenous leukemia (CML). The nurse knows that the client is at risk for tumor lysis syndrome. Which of the following laboratory values requires immediate intervention?

• A. Increased uric acid level
• B. Increased serum potassium level
• C. Increased serum sodium level
• D. Increased fibrinogen level

Correct answer: A

Rationale: The correct answer is A: Increased uric acid level. In tumor lysis syndrome, rapid cell destruction releases large amounts of potassium, phosphate, and nucleic acids into the bloodstream. Uric acid can accumulate rapidly, leading to hyperuricemia, which can result in kidney damage due to urate crystal deposition. Immediate intervention is necessary to prevent renal complications. Choices B, C, and D are incorrect because while electrolyte imbalances are common in tumor lysis syndrome, hyperuricemia with potential kidney damage is the priority concern that requires immediate attention.

3. A client is receiving rituximab and asks how it works. What response by the nurse is best?

• A. It causes rapid lysis of the cancer cell membranes.
• B. It destroys the enzymes needed to create cancer cells.
• C. It prevents the start of cell division in the cancer cells.
• D. It sensitizes certain cancer cells to chemotherapy.

Correct answer: C

Rationale: Rituximab is a monoclonal antibody that targets CD20, a protein found on the surface of certain B-cells, including some cancerous B-cells, such as in non-Hodgkin's lymphoma and chronic lymphocytic leukemia (CLL). Rituximab works by binding to the CD20 protein, which leads to the destruction of the cancerous B-cells through various mechanisms, including preventing the initiation of cell division. By blocking the division process, rituximab helps slow the growth and proliferation of cancer cells, allowing the immune system and additional treatments to clear them more effectively.

4. 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).

5. All of the following are warning signs of cancer except:

• A. Patient palpates a bump on the side of the breast
• B. Bruises are found on the body that the client cannot explain
• C. Patient often complains of impaired digestion
• D. Patient has blood-tinged sputum

Correct answer: D

Rationale: The correct answer is D. Blood-tinged sputum is not a typical warning sign of cancer but rather a symptom that can indicate other serious conditions like respiratory issues or infections. Choices A, B, and C are common warning signs of cancer: palpable lumps or bumps, unexplained bruises, and persistent digestive issues are often associated with cancer and should be evaluated by a healthcare professional for further assessment and diagnosis.
