The Hematologic System ATI Questions
Question 1 of 5
A nurse is caring for a client who is about to begin factor VIII therapy to treat hemophilia A. When administering factor VIII, which of the following actions should the nurse take?
Correct Answer: D
Rationale: The correct answer is D. Having emergency equipment ready is crucial when administering factor VIII therapy for hemophilia A due to the risk of potential allergic reactions or adverse events. The nurse should be prepared to manage any complications promptly. Administering the powdered form orally (A) is incorrect as factor VIII is typically given intravenously. Premedicating with aspirin (B) is contraindicated as aspirin can increase the risk of bleeding in hemophilia patients. Administering it via rapid IV bolus (C) is also unsafe as it can cause adverse reactions and should be infused slowly.
Question 2 of 5
A nurse is administering epoetin intravenously to a client who has renal failure. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Administer via IV bolus over 1 to 3 min. This route and method of administration is appropriate for epoetin to ensure proper absorption and effect. Shaking the vial (A) can denature the drug. Diluting with D5W (C) is not recommended as it may alter the drug's effectiveness. Saving the used vial for the next dose (D) is unsafe and violates infection control practices.
Question 3 of 5
The International Normalized Ratio (INR) was developed for the purpose of
Correct Answer: D
Rationale: The correct answer is D because the International Normalized Ratio (INR) was specifically developed to standardize the monitoring of warfarin therapy. INR allows for consistent interpretation of prothrombin time results across different laboratories, ensuring accurate dosing of warfarin. Choice A is incorrect because heparin therapy is typically monitored using activated partial thromboplastin time (aPTT). Choice B is incorrect as INR, not aPTT, is used for monitoring oral anticoagulant therapy such as warfarin. Choice C is incorrect as INR is not used for screening clotting system abnormalities, but rather for monitoring anticoagulant therapy.
Question 4 of 5
According to the FAB classification, the L2 stage is characterized by:
Correct Answer: C
Rationale: The correct answer is C because according to the FAB classification, the L2 stage is characterized by large homogenous blasts with scanty nucleoli and a higher nucleus to cytoplasm ratio. This is because in the L2 stage, the blasts are more immature and have a larger size compared to other stages. Choice A is incorrect because it describes blasts with prominent nucleoli, which is not characteristic of the L2 stage. Choice B is incorrect because it describes small homogenous blasts with scanty nucleoli, which does not align with the characteristics of the L2 stage. Choice D is incorrect because it describes large blasts with basophilic vacuolated cytoplasm, which is not a feature of the L2 stage.
Question 5 of 5
The nurse is concerned that a patient is demonstrating signs of red blood cell production. What laboratory value did the nurse most likely use to make this decision?
Correct Answer: B
Rationale: The correct answer is B: Bilirubin. Bilirubin is a product of red blood cell breakdown and its levels can indicate the rate of red blood cell production. Elevated bilirubin can suggest increased RBC destruction or hemolysis. Iron (A) is related to anemia but not a direct indicator of RBC production. Thrombin (C) is a clotting factor, not related to RBC production. Intrinsic factor (D) is involved in vitamin B12 absorption, not directly linked to RBC production.
