The nurse is addressing condom use in the context of a health promotion workshop. When discussing the correct use of condoms, which instruction should the nurse give the attendees?

Correct Answer: D

Rationale: The correct answer is D: Hold the condom during withdrawal so it doesn't come off. This is crucial to prevent slippage and potential exposure to sexually transmitted infections or unintended pregnancy. Holding the condom during withdrawal maintains its position and reduces the risk of breakage. A: Applying the condom prior to erection is incorrect as it may lead to slippage. B: Reusing a condom is unsafe and increases the risk of breakage and transmission of infections. C: Using skin lotion as a lubricant is not recommended as it can damage the condom and increase the risk of breakage.

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: C

Rationale: The correct answer is C, acute lymphocytic leukemia. In this disease, bone marrow transplantation is not indicated as it is a systemic cancer affecting the blood and bone marrow itself. Transplanting diseased bone marrow would not be effective in treating the underlying cancer. In contrast, severe aplastic anemia (A) and severe combined immunodeficiency (B) are conditions where bone marrow transplantation can help replace dysfunctional bone marrow with healthy stem cells. Chronic myeloid leukemia (D) may also benefit from bone marrow transplantation as a treatment option to replace cancerous cells with healthy ones.

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.
