The Hematologic System ATI Questions
Question 1 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 2 of 5
A patient is being prepared to receive a prescribed blood transfusion. What is the best way that the LPN can assist the health team to prevent a transfusion reaction?
Correct Answer: D
Rationale: The correct answer is D: Assist the registered nurse (RN) to identify correctly the patient and the blood product. This is crucial to prevent transfusion reactions as it ensures the right blood is given to the right patient. Misidentification can lead to severe complications. Monitoring vital signs (A) is important but doesn't directly prevent transfusion reactions. Warming blood (B) may improve patient comfort but doesn't prevent reactions. Administering diphenhydramine (C) is not a standard pre-transfusion medication and should not be given without specific orders. Identifying the patient and blood product correctly is the best way to prevent transfusion reactions.
Question 3 of 5
A patient is prescribed a transfusion of washed packed red blood cells. What should the nurse realize as being the rationale for the using this type of blood?
Correct Answer: C
Rationale: The correct answer is C because washing packed red blood cells reduces the risk of a febrile reaction by removing white blood cells, plasma proteins, and other substances that could lead to an immune response. Choice A is incorrect as hypothermia is not a primary concern with washed packed red blood cells. Choice B is incorrect as the process does not cleanse blood cells of impurities. Choice D is incorrect as the main purpose of washing blood cells is to reduce the risk of adverse reactions, not to remove harmful particles.
Question 4 of 5
The nurse is assisting with the collection of data from a patient with a hematologic disorder. On which body system should the nurse expect to focus when collecting this data?
Correct Answer: D
Rationale: The correct answer is D because hematologic disorders affect all body systems due to their impact on blood production, clotting, and oxygen transport. The nurse needs to assess respiratory system for oxygenation, genitourinary system for kidney function, cardiovascular system for circulation, and other systems for secondary effects. Choices A, B, and C are incorrect as they focus on specific systems, while hematologic disorders can impact multiple systems. It is important to consider the interconnectedness of the body and assess all systems comprehensively.
Question 5 of 5
A patient's complete blood count (CBC) shows a hemoglobin of 19 g/dL and a hematocrit of 54%. Which question should the nurse ask to determine possible causes of this finding?
Correct Answer: B
Rationale: The correct answer is B: Do you have any history of lung disease? A high hemoglobin and hematocrit can be indicative of chronic hypoxia, often seen in lung diseases like COPD. The nurse should ask about lung disease to explore the possibility of chronic hypoxia as the underlying cause. Choices A, C, and D are incorrect as they do not directly relate to the potential cause of elevated hemoglobin and hematocrit levels in this scenario.
