NR 507 Final CORRECT QUESTIONS & ANSWERS
2024 LATEST UPDATE!!!

thwart infection by pathogenic microorganisms
Two Types of Innate Immunity - ANSWER Natural Barriers (physical, mechanical, and biochemical) and
Inflammation
Adaptive (Acquired) Immunity - ANSWER Third line of defense that is initiated when innate immune
system signals the cells of adaptive immunity. Responsive toward a very specific antigen. Develops slowly
during first exposure, but is immediate at second exposure.
Cells of Adaptive Immunity - ANSWER T Lymphocytes, B lymphocytes, macrophages, dendritic cells
Cells of Innate Immunity - ANSWER Mast cells, granulocytes (neutrophils, eosinophils, basophils), Natural
Killer cells, platelets, and endothelial cells
The relationship between arterial perfusion and alveolar gas pressure at the base of the lungs - ANSWER
arterial perfusion pressure exceeds alveolar gas pressure
When an individual is in an upright position - ANSWER gravity pulls the lungs down toward the
diaphragm and compresses the bases of the lungs
Psoriasis, pityriasis rosea, lichen planus - ANSWER inflammatory disorders characterized by papules,
scales, plaques, and erythema

women of childbearing age, and children.
IDA can cause _______ in children - ANSWER cognitive impairment that is not reversible
Sideroblastic anemias - ANSWER A microcytic-hypochromic anemia caused by a defect in mitochondrial
heme synthesis. Characterized by ringed side roblasts within the bone marrow. Defects in mitochondrial
metabolism lead to ineffective iron uptake and dysfunctional heme synthesis. The ringed sideroblast is
an erythroblast containing iron granules arranged around the nucleus
Types of normocytic-normochromic anemias - ANSWER aplastic, posthemorrhagic, acquired hemolytic,
hereditary hemolytic, and anemia of chronic inflammation
Aplastic anemia - ANSWER A normochromic-normocytic characterized by pancytopenia (reduction of all
three blood cell types) resulting from failure or suppression of bone marrow to produce adequate
amounts of blood cells
Posthemorrhagic anemia - ANSWER A normochromic-normocytic anemia caused by acute blood loss.
Clinical manifestations are related to loss of volume, not loss of hemoglobin
Hemolytic anemias - ANSWER normocytic-normochromic anemias that result from premature,
accelerated destruction of erythrocytes. Results in elevated levels of erythropoietin and the products of
hemoglobin catabolism
