You are preparing the client for a bone marrow aspiration and biopsy. Which of the following statements, if made by the patient, indicates the need for further teaching?

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Ambulation is encouraged after a bone marrow aspiration to prevent blood clots. 2. Prolonged immobility can increase the risk of complications like deep vein thrombosis. 3. Therefore, the statement indicating to avoid ambulating for 24-48 hours is incorrect and requires further teaching. 4. Other choices (B, C, D) are appropriate and do not raise any concerns regarding patient understanding.

Correct Answer: D

Rationale: The correct answer is D: An undetermined cause. Autoimmune hemolytic anemia often has an idiopathic or unknown cause. Here's a rationale: 1. Autoimmune hemolytic anemia is a complex disorder with various underlying mechanisms, making it challenging to pinpoint a single cause. 2. While some cases may be associated with certain factors like drug use (choice C) or coexisting autoimmune disorders (choice B), these do not account for most cases. 3. Genetic anomalies (choice A) may play a role in some instances, but they do not universally cause autoimmune hemolytic anemia. 4. Choice D is the most appropriate as it acknowledges the complexity of the disorder and the fact that a significant portion of cases lack a clear, identifiable cause.

Correct Answer: D

Rationale: The correct answer is D: Inadequate production of white blood cells. Anemia is specifically related to red blood cells and hemoglobin, not white blood cells. White blood cells are part of the immune system and are responsible for fighting infections, not oxygen transport. Choices A, B, and C are incorrect because they directly impact red blood cell count or hemoglobin levels, which are essential for oxygen transport in the body. Blood loss leads to a decrease in red blood cells, excessive destruction of red blood cells reduces the total count, and inadequate production of red blood cells results in a low number of functional cells.

Correct Answer: D

Rationale: The correct answer is D: Blood clotting factor transfusions. This is the appropriate treatment for bleeding episodes in people with hemophilia as they lack certain clotting factors. Transfusing these missing clotting factors helps to stop the bleeding. Explanation: 1. Aspirin (Choice A) is not recommended for hemophilia patients as it can increase the risk of bleeding due to its antiplatelet effects. 2. Blood clotting drugs (Choice B) may not be as effective as transfusions of specific clotting factors in treating bleeding episodes in hemophilia. 3. Gene therapy (Choice C) is a promising treatment for hemophilia, but it is not yet widely available and may not be the immediate solution for acute bleeding episodes.

Correct Answer: A

Rationale: The correct answer is A: Inadequate production of Hb. Anemia is classified based on the underlying mechanism causing decreased hemoglobin levels. Inadequate production of hemoglobin is one of the classifications, encompassing conditions like iron deficiency anemia. Decreased RBC production (choice B) is a broader classification that includes various causes like bone marrow disorders. Increased erythrocyte destruction (choice C) refers to hemolytic anemias where red blood cells are destroyed prematurely. Blood loss (choice D) is a separate classification related to acute or chronic bleeding. Therefore, the correct answer specifically addresses the primary issue of insufficient hemoglobin production in anemia.
