Hematologic System Questions Questions
Question 1 of 5
Which of the following would the nurse perform to help alleviate a child’s joint pain associated with rheumatic fever?
Correct Answer: D
Rationale: The correct answer is D because using a bed cradle helps alleviate joint pain by avoiding pressure from bed linens. This reduces stress on the joints, promoting comfort and preventing further inflammation. Maintaining joints in an extended position (A) may worsen pain. Applying traction (B) can potentially aggravate the joints. Supporting alignment with pillows (C) may not directly address joint pain relief. Thus, D is the most suitable choice for alleviating joint pain in rheumatic fever.
Question 2 of 5
Which of the following is the predominant route by which pathogens are brought from a site of infection into a lymph node?
Correct Answer: D
Rationale: The correct answer is D: afferent lymphatics. Afferent lymphatics are the vessels that carry lymph fluid from the site of infection to the lymph node, allowing pathogens to be transported to the lymph node for immune response. Efferent lymphatics (choice A) carry lymph away from the lymph node, arteries (choice B) carry oxygenated blood, and veins (choice C) carry deoxygenated blood, none of which are the primary route for pathogens to reach the lymph node.
Question 3 of 5
The nurse is aware that blood type O is considered the universal donor. This means all patients can receive blood type O. Knowing this, which of the following statements is correct. (Select one that does not apply)
Correct Answer: D
Rationale: The correct answer is D because the statement is incorrect. A client with blood type AB cannot receive blood type ABO, as ABO is not a specific blood type. Blood type ABO includes blood types A, B, AB, and O. Therefore, the statement is nonsensical and misleading. Blood type AB can receive blood types A and B, but not ABO as a whole. Choices A, B, and C are incorrect because they correctly state that a client with blood type AB can receive blood types A, B, and O, respectively.
Question 4 of 5
Which sickle cell disorder causes the most severe symptoms?
Correct Answer: A
Rationale: Step 1: Sickle cell anemia is the correct answer because it results from inheriting two abnormal hemoglobin genes causing severe symptoms. Step 2: Sickle cell-thalassemia is incorrect because it involves a combination of sickle cell gene and thalassemia gene but generally milder symptoms. Step 3: Sickle cell-HbC disease is incorrect as it involves a different type of abnormal hemoglobin gene and typically milder symptoms compared to sickle cell anemia. Step 4: Sickle cell trait is incorrect because it results from inheriting one abnormal hemoglobin gene and usually has no or mild symptoms.
Question 5 of 5
A nurse is reviewing a client's repeat laboratory results 4 hr after administering fresh frozen plasma (FFP). Which of the following laboratory results should the nurse review?
Correct Answer: A
Rationale: The correct answer is A: Prothrombin time. Prothrombin time measures the time it takes for blood to clot, which is crucial after administering fresh frozen plasma (FFP) to assess its effectiveness in improving clotting factors. Hemoglobin level, platelet count, and white blood cell count are not directly affected by FFP administration and would not provide specific information on clotting status.
