The Hematologic System ATI Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A patient has an altered level of T and B cells. The nurse realizes that these cells are members of which cell type?
Correct Answer: C
Rationale: The correct answer is C: Lymphocytes. T and B cells are subtypes of lymphocytes, which are crucial components of the immune system. T cells are involved in cell-mediated immunity, while B cells are responsible for producing antibodies. Platelets (A), eosinophils (B), and red blood cells (D) do not have the same functions or roles as T and B cells in the immune system. Platelets are involved in blood clotting, eosinophils are a type of white blood cell involved in allergic reactions, and red blood cells are responsible for oxygen transport.
Question 5 of 5
A patient has a bone marrow aspiration from the posterior iliac crest. Before the procedure, the patient's vital signs were: blood pressure 132/82 mm Hg and pulse 88 beats/min. One hour after the procedure, the blood pressure is 108/70 mm Hg and pulse is 96 beats/min. Which assessment is the least important for the patient at this time?
Correct Answer: B
Rationale: The correct answer is B because the patient's vital signs have changed post-procedure, indicating a potential complication. Checking the complete blood count report is the least important at this time as it does not immediately impact the patient's current condition. A: Observing the puncture site is important to assess for bleeding or infection. C: Asking about lightheadedness or dizziness is crucial to monitor for signs of hypovolemia or shock. D: Determining medications taken before the procedure is essential to identify any potential interactions or adverse effects. In summary, monitoring vital signs, assessing the puncture site, and checking for symptoms of hypovolemia or shock are more critical post-procedure than reviewing the complete blood count report.
