Correct Answer: B

Rationale: The correct answer is B: Hemorrhage. Patients with acute myelogenous leukemia are at high risk of hemorrhage due to low platelet count and abnormal clotting factors caused by bone marrow suppression. Pancreatitis (choice A) is not a common complication of acute myelogenous leukemia. Arteritis (choice C) refers to inflammation of arteries and is not a typical complication of this type of leukemia. Liver dysfunction (choice D) is not a primary concern in the immediate care plan for a patient with acute myelogenous leukemia.

Correct Answer: B

Rationale: The correct answer is B: Reed-Sternberg cells. In Hodgkin lymphoma, the presence of Reed-Sternberg cells in lymph node biopsy is diagnostic. These cells are large, atypical cells originating from B-lymphocytes. They are distinctive in appearance and are key to diagnosing Hodgkin lymphoma. Choices A, C, and D are incorrect because Schwann cells are related to nerve function, Lewy bodies are associated with Parkinson's disease, and Loops of Henle are structures in the kidney, none of which are specific to Hodgkin lymphoma.

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: 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.

Correct Answer: A

Rationale: The correct answer is A: Vital signs. Monitoring vital signs is crucial during the infusion of monoclonal antibody therapy as there is a risk of infusion reactions such as fevers, chills, hypotension, and tachycardia. Assessing vital signs allows for early detection of any adverse reactions, enabling prompt intervention. Skin reactions (choice B), respiratory status (choice C), and renal function (choice D) are important assessments in general patient care but are not the priority during the infusion of monoclonal antibody therapy.
