Anatomy of Hematologic System Questions
Question 1 of 5
A nurse is caring for a client who is experiencing an acute ischemic cerebrovascular event due to a thrombus in a cerebral vessel. Which of the following drugs should the nurse expect to administer?
Correct Answer: A
Rationale: The correct answer is A: Alteplase. Alteplase is a thrombolytic agent used to dissolve blood clots and restore blood flow in acute ischemic stroke. It is crucial to administer within a specific time frame for the best outcome. Aspirin (B) and Clopidogrel (C) are antiplatelet agents that prevent further clot formation but are not used for immediate clot dissolution in acute ischemic stroke. Heparin (D) is an anticoagulant that prevents clot formation and is not typically used as the initial treatment for acute ischemic stroke.
Question 2 of 5
A laboratory finding of granulocytosis
Correct Answer: D
Rationale: The correct answer is D because granulocytosis refers to an increase in granulocytes in both blood and bone marrow. This finding is commonly seen in conditions such as infections and inflammatory processes. The other choices are incorrect because A describes agranulocytosis, B is a potential cause of granulocytosis, and C typically involves abnormal proliferation of myeloid cells rather than just granulocytes.
Question 3 of 5
The nurse is reviewing the parts of the complete blood count and differential with a patient. Where should the nurse state that neutrophils, eosinophils, and basophils are produced?
Correct Answer: D
Rationale: The correct answer is D: Red bone marrow. Neutrophils, eosinophils, and basophils are all types of white blood cells that are produced in the red bone marrow through a process called hematopoiesis. The red bone marrow is a primary site for the production of blood cells, including these specific types of white blood cells. Neutrophils are important for fighting bacterial infections, eosinophils are involved in allergic reactions and parasitic infections, and basophils play a role in allergic responses. Therefore, it is crucial for the nurse to inform the patient that these cells are produced in the red bone marrow. The other choices (A: Spleen, B: Thymus, C: Lymph nodes) are incorrect as these organs do not play a primary role in the production of these specific types of white blood cells.
Question 4 of 5
The nurse is documenting findings after completing data collection with a patient. What term should the nurse use to document a large area of discoloration from hemorrhage under the skin?
Correct Answer: D
Rationale: The correct term to document a large area of discoloration from hemorrhage under the skin is ecchymosis. Ecchymosis refers to a bruise caused by the extravasation of blood into the subcutaneous tissues. Pallor (A) is paleness, rubor (B) is redness, and petechiae (C) are tiny, pinpoint-sized red or purple spots on the skin due to bleeding. Ecchymosis is the most appropriate term for describing a large area of discoloration from hemorrhage under the skin as it specifically denotes a bruise resulting from blood leakage into tissues.
Question 5 of 5
The nurse is monitoring a patient receiving a blood product and is concerned that the blood is going to deteriorate before it is complete infused. What is the maximum time that blood can hang during infusion before it begins to deteriorate?
Correct Answer: D
Rationale: The correct answer is D: 4 hours. Blood products typically have a maximum hang time of 4 hours to prevent bacterial contamination and ensure the integrity of the product. Beyond 4 hours, the risk of bacterial growth and contamination increases, leading to potential harm for the patient. Therefore, it is crucial to adhere to this time limit to maintain the safety and effectiveness of the blood product. Summary: - A (1 hour), B (2 hours), and C (3 hours) are incorrect because they do not align with the standard maximum hang time for blood products, which is 4 hours. Adhering to this time limit is essential to prevent deterioration and ensure patient safety.
