ATI RN
The Hematologic System ATI Questions
Question 1 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. Elevated levels of bilirubin can indicate increased red blood cell breakdown or hemolysis, prompting the body to produce more red blood cells to compensate for the loss. Iron (A) is involved in red blood cell production but is not a direct indicator. Thrombin (C) is a clotting factor, not related to red blood cell production. Intrinsic factor (D) is necessary for vitamin B12 absorption, not directly linked to red blood cell production. Therefore, Bilirubin is the most likely laboratory value used to indicate increased red blood cell production.
Question 2 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: Check the patient's most recent complete blood count report. This assessment is the least important at this time because changes in vital signs post-bone marrow aspiration are more indicative of immediate complications such as bleeding or shock, which require prompt attention. Checking the complete blood count report would not provide immediate actionable information in this acute situation. Summary: A: Observing the puncture site is important for signs of bleeding or infection. C: Asking the patient about lightheadedness or dizziness is crucial to assess for signs of hypovolemia or shock. D: Determining if the patient had any medications before the procedure is essential to identify possible adverse drug interactions.
Question 3 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: Correct Answer: D Rationale: 1. Identifying the patient and blood product is crucial to prevent transfusion reactions. 2. Matching the patient's identity with the blood product minimizes risk of incompatibility. 3. This step ensures the right blood type and product are administered, preventing serious reactions. 4. LPNs play a key role in assisting the RN in verifying and confirming patient and blood product identity. Summary: A: Monitoring vital signs is important but doesn't directly prevent transfusion reactions. B: Warming blood can improve patient comfort but does not prevent reactions. C: Administering Benadryl addresses possible allergic reactions but doesn't prevent incompatibility issues.
Question 4 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: Reduces the risk of a febrile reaction. Washed packed red blood cells are used to remove plasma proteins, white blood cells, and platelets, reducing the risk of febrile reactions caused by leukocytes and cytokines. Choice A is incorrect because washing red blood cells does not impact the risk of hypothermia. Choice B is incorrect as washing does not clean the cells of impurities. Choice D is incorrect as the washing process does not remove harmful particles from the blood.
Question 5 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: All body systems. When assessing a patient with a hematologic disorder, the nurse needs to consider the impact on multiple body systems. Hematologic disorders can affect the cardiovascular system (such as anemia or clotting disorders), respiratory system (such as decreased oxygen-carrying capacity), genitourinary system (such as kidney dysfunction in conditions like hemolytic uremic syndrome), and other systems. By focusing on all body systems, the nurse ensures a comprehensive assessment to identify any potential complications or manifestations related to the hematologic disorder. Choices A, B, and C are incorrect because hematologic disorders can have implications beyond these specific systems, necessitating a more holistic approach to data collection.
