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, supporting the treatment of iron deficiency anemia. The rationale is that consuming foods rich in iron can complement the effects of ferrous sulfate, aiding in the replenishment of iron stores. Summary: - B: Spreading the dosage throughout the day can help with better absorption, but it is not the priority instruction. - C: Taking the drug on an empty stomach can enhance absorption, but it may also cause stomach upset. - D: Reporting dark green or black stools is important to monitor for possible gastrointestinal bleeding, but it is not an instruction for 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 medication used to dissolve blood clots and is crucial in treating acute ischemic cerebrovascular events caused by thrombus. It helps restore blood flow to the affected area of the brain. Aspirin (B) and Clopidogrel (C) are antiplatelet medications that prevent clot formation but do not dissolve existing clots. Heparin (D) is an anticoagulant that does not directly dissolve clots like Alteplase. Administering Alteplase promptly is essential to minimize brain damage in such emergencies.
Question 3 of 5
During haemostasis, prostacyclin
Correct Answer: B
Rationale: Prostacyclin is a vasodilator that inhibits platelet aggregation and promotes fibrinolysis. Vasodilation helps reduce blood pressure, improve blood flow, and prevent clot formation. Therefore, choice B is correct. Choice A is incorrect as prostacyclin does not cleave prothrombin. Choice C is incorrect as prostacyclin inhibits platelet aggregation. Choice D is incorrect as prostacyclin does not activate fibrinolysis.
Question 4 of 5
A laboratory finding of granulocytosis
Correct Answer: D
Rationale: The correct answer is D because granulocytosis refers to an increased number of granulocytes in both blood and bone marrow. This finding is commonly associated with conditions such as infections, inflammation, and certain hematologic disorders. Other choices are incorrect because A describes a condition of granulocytopenia, B is associated with acute bacterial infections but not specific to granulocytosis, and C refers to myeloproliferative disorders which may involve other cell types besides 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. Red bone marrow is the primary site of hematopoiesis in adults, where all blood cells, including white blood cells, are produced. The red bone marrow contains stem cells that differentiate into various types of blood cells, including neutrophils, eosinophils, and basophils. Therefore, the nurse should explain to the patient that these specific types of white blood cells are produced in the red bone marrow. The other choices (A: Spleen, B: Thymus, C: Lymph nodes) are incorrect because they are not the primary sites for the production of these specific white blood cells.
