Hematological System Questions
Question 1 of 4
Which is associated with prolonged bleeding time:
Correct Answer: B
Rationale: The correct answer is B: Von Willebrand disease. Von Willebrand factor plays a crucial role in platelet adhesion and clot formation. Deficiency or dysfunction of this factor leads to prolonged bleeding time. Choice A, polycythemia vera, is associated with increased red blood cell production but does not directly affect bleeding time. Choice C, antiphospholipid syndrome, causes blood clots rather than prolonged bleeding. Choice D, hemophilia, is a clotting disorder but does not necessarily result in prolonged bleeding time.
Question 2 of 4
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, there is a high risk of bleeding due to low platelet count and abnormal clotting factors. The nurse should address this potential complication by closely monitoring the patient for signs of bleeding, providing platelet transfusions if necessary, and taking precautions to prevent injury. Pancreatitis (A), Arteritis (C), and Liver dysfunction (D) are not commonly associated with acute myelogenous leukemia.
Question 3 of 4
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 WBC count are common signs of an infection. 2. These symptoms are indicative of the body's immune response to fight off pathogens. 3. Infections are a common cause of elevated WBC count and systemic symptoms. 4. Considering the patient's presentation, infection is the most probable diagnosis. Summary: A: Assessing for lymphoma is premature and not supported by the patient's symptoms. C: Signs and symptoms of leukemia typically involve other specific findings beyond those described. D: Diagnostic testing for multiple myeloma is not warranted based on the patient's presentation.
Question 4 of 4
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 has a low potential for spreading aggressively or becoming malignant. This implies that the patient is at a significant risk of malignancy as the neoplasm may progress over time. Choice B is incorrect because an indolent neoplasm does not necessarily indicate myeloid leukemia. Choice C is incorrect because it does not specify the type of leukemia associated with an indolent neoplasm. Choice D is incorrect because hemophilia is not directly related to the characteristics of an indolent neoplasm.
