In this concise NCLEX‑focused lecture, the speaker walks through the essential signs and symptoms of pernicious anemia, emphasizing its underlying pathophysiology. The talk explains that intrinsic factor produced in the stomach is required for vitamin B12 synthesis, which in turn is essential for red blood cell production. A deficiency leads to anemia, producing systemic manifestations such as lethargy, fatigue, shortness of breath, and pallor. The speaker highlights the hallmark oral finding—smooth, tender, beefy‑red tongue, also known as atrophic glossitis—as a high‑yield NCLEX clue. The overall purpose is to equip nursing students with memorable, exam‑relevant details about the disease’s cause and presentation.

Lets walk through the key signs and symptoms that you'll need to know about pernicious anemia for the nclex. Now pernicious anemia is really interesting because it's all about the stomach and intrinsic factor. Intrinsic factor in the stomach is necessary to make vitamin B12 and vitamin B12 is necessary to make red blood cells and ding, ding, ding, without red blood cells we get all of these signs and symptoms of pernicious anemia symptoms simply because there's that lack of red blood cells. There is that anemia. Now smooth, tender, beefy, red tongue is often what you'll see it referred to as that is a hallmark sign of pernicious anemia and the NCLEX loves to test on that. So definitely remember that it's also called atrophic glossitis. Now you could also see lethargy, tiredness, shortness of breath, pale complexion. These are all because of that lack of red blood cells, that lack of hemoglobin in the body to get perfusion and oxygen to the T. Use.
