Select all that apply: Pernicious anemia is most common in older people. Which choice lists the correct relationships among the factors that cause this disorder? The reduced secretion of intrinsic factor means that vitamin B12 cannot be absorbed, and macrocytes are produced instead of erythrocytes. The reduced synthesis of vitamin B12 results in the production of too many platelets. The reduced secretion of intrinsic factor means that vitamin B12 cannot be absorbed, and too many red blood cells are destroyed. The increased secretion of intrinsic factor results in excess levels of vitamin B12, which causes the synthesis of too many red blood cells for the spleen to break down.

Background: The hematocrit of whole blood is the percent of the blood (by volume) that is made up of cells. For example, if a person has a hematocrit of 40, it means that 40% of the blood volume is cells and the rest is plasma. The average hematocrit of a normal human male is 42 and 38 for a normal human female. The degree of bodily activity, anaemia, as well as altitude, are among some factors that affect hematocrits. calculation to get the % red blood cells (RBC): RBC present over total liquid x 100 The tubes in the image were all centrifuged at maximum speed for 5 minutes. Describe your observations of the hypo-, iso-, and hypertonic hematocrit tubes. Also calculate the % volume of red blood cells in each tube.

Category: Physiological Adaptation A 46-year-old patient with Chronic Lymphocytic Leukemia (CLL) expresses confusion to the nurse about the development of anemia despite the disease’s characteristic increased white blood cell production. The patient presents with fatigue and pallor, common symptoms of anemia. To address the patient’s concern, how should the nurse best explain the reason for anemia in the context of CLL? A. The overproduction of white blood cells can crowd out red blood cells in the bone marrow. B. The presence of anemia is unrelated to the proliferation of white blood cells. C. The excessive white blood cells consume nutrients that would otherwise nourish red blood cells. D. The abnormal white blood cells have a reduced lifespan, which does not affect red blood cells.
