The mother asks the nurse if her child's iron deficiency anemia is related to the child's frequent infections. The nurse responds based on the understanding of which of the following?

Correct Answer: B

Rationale: The correct answer is B: Children with iron deficiency anemia are more susceptible to infection than are other children. Iron is crucial for the immune system to function optimally. In iron deficiency anemia, the body lacks enough iron to produce hemoglobin, which can impair the immune response, making individuals more prone to infections. Therefore, children with iron deficiency anemia are indeed more susceptible to infections. Explanation of other choices: A: Little is known about iron-deficiency anemia and its relationship to infection in children - This is incorrect as there is a clear understanding of the link between iron deficiency anemia and susceptibility to infections. C: Children with iron-deficiency anemia are less susceptible to infection than are other children - This is incorrect as iron deficiency impairs the immune response, making individuals more susceptible to infections. D: Children with iron-deficient anemia are equally as susceptible to infection as are other children - This is incorrect as iron deficiency compromises the immune system, leading to increased susceptibility to

Correct Answer: A

Rationale: The correct answer is A: Excessive Bleeding. Polycythemia Vera is a condition characterized by an overproduction of red blood cells, leading to increased blood viscosity and risk of thrombosis. Due to the increased number of red blood cells, there is a higher risk of clot formation, which can result in complications such as thrombosis, stroke, or heart attack. Excessive bleeding can also occur as a result of abnormal blood clotting mechanisms in Polycythemia Vera. Pruritus (choice B) is a common symptom but not a direct complication of Polycythemia Vera. Hepatomegaly (choice C) and Pancreatitis (choice D) are not commonly associated complications of Polycythemia Vera.

Correct Answer: D

Rationale: The correct answer is D: Too few white blood cells. Leukopenia refers to a decrease in white blood cells. White blood cells are crucial for the immune system to fight infections. Easy bleeding and bruising (A) are associated with low platelets, not white blood cells. Too few red blood cells (C) is known as anemia. While white blood cells are important for immunity, platelets help with blood clotting, and red blood cells carry oxygen.

Correct Answer: A

Rationale: The correct answer is A: Applying pressure to the biopsy site. This is the priority post-procedure as it helps prevent bleeding and hematoma formation. Applying pressure aids in achieving hemostasis, reducing the risk of complications. Choice B is incorrect as inspecting for ecchymoses is important but not the priority over preventing bleeding. Choice C is also incorrect as sending specimens to the lab can be done after ensuring the client's safety. Choice D is incorrect as teaching about avoiding vigorous activity is important but not the immediate priority post-procedure.

Correct Answer: C

Rationale: The correct answer is C: MCHC. MCHC stands for Mean Corpuscular Hemoglobin Concentration, which is a measure of the average concentration of hemoglobin in a given volume of packed red blood cells. In this case, a saturation of 32-36% indicates the concentration of hemoglobin in the red blood cells. MCV (Mean Corpuscular Volume) measures the average volume of a red blood cell, MCH (Mean Corpuscular Hemoglobin) measures the average amount of hemoglobin in a red blood cell, and RDW (Red Cell Distribution Width) measures the variation in red blood cell size. These parameters do not directly indicate the saturation of hemoglobin in red blood cells, making them incorrect choices for this scenario.
