Hematological System Questions
Question 1 of 5
Decrease iron &decrease iron binding capacity are seen in:
Correct Answer: C
Rationale: The correct answer is C: chronic infection. Chronic infection leads to the release of hepcidin, which decreases iron absorption and iron binding capacity. This results in decreased iron levels. Recurrent GIT bleeding (A) and menorrhagia (D) lead to iron loss, resulting in decreased iron but increased iron binding capacity compensating for the loss. Intestinal resection (B) can lead to decreased iron absorption but not necessarily decreased iron binding capacity.
Question 2 of 5
A nurse is planning the care of a patient who has been admitted to the medical unit with a diagnosis of multiple myeloma. In the patient's care plan, the nurse has identified a diagnosis of Risk for Injury. What pathophysiologic effect of multiple myeloma most contributes to this risk?
Correct Answer: C
Rationale: Step 1: Multiple myeloma is a cancer of plasma cells, leading to bone destruction due to excessive bone resorption. Step 2: Decreased bone density is a common complication of multiple myeloma, increasing the risk of fractures. Step 3: Fractures due to weakened bones can lead to falls and subsequent injuries, supporting the Risk for Injury diagnosis. Summary: Choice C is correct because decreased bone density from multiple myeloma directly contributes to the patient's risk for injury. Choices A, B, and D are incorrect as they are not pathophysiologic effects associated with multiple myeloma.
Question 3 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, 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 4 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 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 5 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 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.
