Anatomy of Hematologic System Questions
Question 1 of 5
A nurse is teaching a client about taking ferrous sulfate to treat iron deficiency anemia. Which of the following instructions should the nurse include? (Select All)
Correct Answer: A
Rationale: The correct answer is A: Eat iron-enriched foods. Iron-enriched foods help increase iron levels in the body, aiding in treating iron deficiency anemia. Consuming these foods along with ferrous sulfate can enhance the effectiveness of the treatment. B: Spreading the dosage across each day is important to maintain consistent iron levels but is not the most crucial aspect of treatment. C: Taking the drug on an empty stomach may enhance absorption but can also lead to stomach upset, so it is not necessary for all clients. D: Reporting dark green or black stools is important to monitor for gastrointestinal bleeding, but it is not an instruction related to taking ferrous sulfate.
Question 2 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 3 of 5
During haemostasis, prostacyclin
Correct Answer: B
Rationale: Prostacyclin is a vasodilator, which means it causes blood vessels to widen, leading to decreased blood pressure and increased blood flow. During haemostasis, this vasodilation helps in maintaining blood flow and preventing platelet aggregation in the damaged area. Option A is incorrect because prostacyclin does not cleave prothrombin into thrombin. Option C is incorrect as prostacyclin inhibits platelet aggregation. Option D is incorrect because prostacyclin does not directly activate fibrinolysis. In summary, the correct answer is B because prostacyclin's vasodilation function plays a crucial role in haemostasis by preventing excessive clot formation and maintaining blood flow.
Question 4 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 5 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.
