Correct Answer: C

Rationale: The correct answer is C. Taking aspirin is not recommended during periods of bone marrow suppression as it can increase the risk of bleeding. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that can impair platelet function, further exacerbating the risk of bleeding. Choices A, B, and D are all appropriate statements for a client at risk for bleeding and undergoing chemotherapy. Blowing the nose gently, being prepared for a platelet transfusion if needed, and monitoring menstrual bleeding are all important aspects of self-care during this period.

Correct Answer: A

Rationale: The correct answer is monitoring for infection. In patients with acute leukemia, the most common cause of death is usually infection or bleeding. By closely monitoring for signs of infection, such as fever, altered mental status, or elevated white blood cell count, healthcare providers can intervene promptly. Monitoring nutritional status (choice B) is important but does not directly address the most common cause of death among leukemia patients. Monitoring electrolyte levels (choice C) and liver function (choice D) are also important assessments in cancer patients; however, they are not the most direct assessment to address the leading cause of death in patients with leukemia.

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.

Correct Answer: C

Rationale: The correct answer is C. A BUN level of 18 mg/dL is within the normal range; however, since cisplatin is nephrotoxic, it requires close monitoring. Elevated BUN levels can indicate impaired kidney function. Choices A, B, and D are within normal ranges and do not directly relate to cisplatin therapy or require immediate intervention.

Correct Answer: B

Rationale: The correct advice for a patient with polycythemia vera is to drink plenty of fluids. This helps in reducing the risk of thrombosis by keeping the blood less viscous. Avoiding hot showers (Choice A) is not directly related to managing polycythemia vera. While avoiding tight and restrictive clothing (Choice C) can help improve circulation, it is not the most crucial advice for these patients. Avoiding prolonged sitting (Choice D) is important to prevent blood clots but is not as critical as staying well-hydrated.
