Hematological System Questions
Question 1 of 5
Which is associated with prolonged bleeding time:
Correct Answer: B
Rationale: The correct answer is B: Von Willebrand disease. This is because Von Willebrand factor plays a crucial role in platelet adhesion and aggregation. A deficiency in Von Willebrand factor leads to impaired platelet function, resulting in prolonged bleeding time. The other choices, polythycemia vera (A), antiphospholipid syndrome (C), and hemophilia (D), are not typically associated with prolonged bleeding time due to different underlying mechanisms. Polythycemia vera is characterized by increased red blood cell production, antiphospholipid syndrome is an autoimmune disorder causing blood clots, and hemophilia is a genetic disorder affecting blood clotting factors.
Question 2 of 5
A patient diagnosed with acute myelogenous leukemia has just been admitted to the oncology unit. When writing this patient's care plan, what potential complication should the nurse address?
Correct Answer: B
Rationale: The correct answer is B: Hemorrhage. In acute myelogenous leukemia, the bone marrow produces abnormal, immature white blood cells, leading to a decrease in platelets and clotting factors, increasing the risk of hemorrhage. This complication is a priority due to the potential life-threatening consequences. Pancreatitis (A) is not directly associated with leukemia. Arteritis (C) is inflammation of arteries, not a common complication of leukemia. Liver dysfunction (D) may occur in leukemia but is not as immediate and critical as hemorrhage.
Question 3 of 5
A nurse practitioner is assessing a patient who has a fever, malaise, and a white blood cell count that is elevated. Which of the following principles should guide the nurse's management of the patient's care?
Correct Answer: B
Rationale: The correct answer is B: Infection is the most likely cause of the patient's change in health status. Rationale: 1. Fever, malaise, and elevated white blood cell count are classic signs of infection. 2. Infections are common causes of elevated white blood cell count. 3. Other choices (A, C, D) focus on specific conditions (lymphoma, leukemia, multiple myeloma) that are less likely in this scenario. 4. It is important to consider the most common and likely cause first, which is infection in this case.
Question 4 of 5
A patient has been found to have an indolent neoplasm. The nurse should recognize what implication of this condition?
Correct Answer: A
Rationale: The correct answer is A because an indolent neoplasm typically grows slowly and is less likely to metastasize quickly, reducing the risk of malignancy. Choice B and C are incorrect as they refer to specific types of leukemia, not necessarily related to indolent neoplasms. Choice D is incorrect as hemophilia is a genetic disorder unrelated to neoplasms. In summary, the key implication of an indolent neoplasm is a lower risk of malignancy compared to aggressive neoplasms.
Question 5 of 5
A nurse in an emergency department is assessing a client who has been taking warfarin and is experiencing rectal bleeding. Which of the following drugs should the nurse expect to administer to the client?
Correct Answer: D
Rationale: The correct answer is D: Vitamin K. Warfarin is an anticoagulant that inhibits Vitamin K-dependent clotting factors, leading to bleeding. Administering Vitamin K helps replenish these factors, aiding in clot formation and stopping the bleeding. Filgrastim (A) is a medication used to stimulate white blood cell production, unrelated to clotting. Deferoxamine (B) is a chelating agent used for iron toxicity, not for clotting issues. Protamine (C) is used to reverse the effects of heparin, not warfarin.
