A client with anemia asks, 'Why am I feeling tired all the time?' How does the nurse respond?

Correct Answer: D

Rationale: The correct answer is D because anemia reduces the number of red blood cells, leading to decreased oxygen delivery to tissues, causing fatigue. The nurse's response highlights the underlying issue of inadequate oxygen supply due to anemia. Choice A focuses on sleep duration, which is not directly related to anemia. Choice B mentions iron deficiency, a common cause of anemia, but it does not address the specific issue of oxygen delivery. Choice C suggests rest for sickness, not addressing the chronic fatigue associated with anemia. Thus, the correct answer D provides a clear and logical explanation for the client's tiredness.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Wilson's disease is a genetic disorder that causes copper to accumulate in the liver. 2. The excess copper can lead to liver damage and various liver problems. 3. Therefore, it is true that Wilson's disease can cause liver problems. Summary: B: False - Incorrect, as Wilson's disease does cause liver problems. C: Sometimes - Incorrect, as Wilson's disease consistently leads to liver problems. D: Only in children - Incorrect, as Wilson's disease can affect individuals of all ages, not just children.

Correct Answer: A

Rationale: The correct answer is A: 120 days. Red blood cells (RBCs) have a lifespan of around 120 days. This is because they do not contain a nucleus and other organelles, limiting their ability to repair and maintain themselves. RBCs are constantly being produced and replaced by the bone marrow. Choices B, C, and D are incorrect as they do not align with the established scientific knowledge regarding the lifespan of RBCs. A lifespan of 100, 200, or 80 days is not consistent with the typical turnover rate and function of red blood cells in the body.

Correct Answer: B

Rationale: The correct answer is B: Lymphocytosis. Chronic Lymphocytic Leukemia is characterized by an increased number of mature lymphocytes in the peripheral blood and bone marrow, leading to lymphocytosis. Lymphocytopenia (choice A) is the opposite of lymphocytosis and is not typical in CLL. Neutropenia (choice C) refers to a low level of neutrophils, which is not a characteristic finding in CLL. Thrombocytosis (choice D) is an increased number of platelets, which is not a defining feature of CLL.

Correct Answer: C

Rationale: The correct answer is C, the end of the 6th month. By this time, the bone marrow becomes the primary site of hematopoiesis in fetal development. This is because around this stage, the bones have developed enough to support the production of blood cells. Prior to the end of the 6th month, hematopoiesis mainly occurs in the liver and spleen. Choices A, B, and D are incorrect because by the 2nd, 5th, and end of 7th month respectively, the liver and spleen are still the main sites of hematopoiesis in fetal development.
