NR 507 Advanced Patho physiology Mid term Exam/ NR 507 Midterm Chamberlain Upda ted 2023 -2024 Score for this quiz: 118 out of 120 Submitted Jul 29 at 7:12am This attempt took 54 minutes. The lung is innervated by the parasympathetic nervous system via which nerve? Vagus Phrenic Question 1 pts Brachial Pectoral Fibers of the parasympathetic division of the autonomic nervous system (ANS) travel only in the vagus nerve to the lung. What is the action of urodilatin? Urodilatin causes vasoconstriction of afferent arterioles. It causes vasodilation of the efferent arterioles. Urodilatin inhibits antidiuretic hormone secretion. Question 2 pts It inhibits salt and water reabsorption. Urodilatin (a natriuretic peptide) inhibits sodium and water reabsorption from the medullary part of collecting duct, thereby producing diuresis. It is not involved in the actions described by the other options. What is the direct action of atrial natriuretic hormone? Sodium retention Sodium excretion Water retention Water excretion Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) inhibit the secretion of renin, inhibit angiotensin -induced secretion of aldosterone, vasodilate the afferent and constrict the efferent glomerular arterioles, and inhibit sodium and wate r absorption by kidney tubules. The other actions are not a result of the atrial natriuretic hormone. Which statement best describes a Schilling test? Question 3 pts Question 4 pts Administration of radioactive cobalamin and the measurement of its excretion in the urine to test for vitamin B12 deficiency Measurement of antigen -antibody immune complexes in the blood to test for hemolytic anemia Measurement of serum ferritin and total iron -binding capacity in the blood to test for iron deficiency anemia Administration of folate and measurement in 2 hou rs of its level in a blood sample to test for folic acid deficiency anemia. The Schilling test indirectly evaluates vitamin B12 abso rption by administering radioactive B12 and measuring excretion in the urine. This selection is the only option that accura tely describes a Schilling test. Hemolytic disease of the newborn (HDN) can occur if the mother: Is Rh-positive and the fetus is Rh-negative Is Rh-negative and the fetus is Rh-positive Has type A blood and the fetus has type O Has type AB blood and the fetus has type B HDN can occur only if antigens on fetal erythrocytes differ from antigens on maternal erythrocytes. Maternal -fetal incompatibility exists only if the mother and fetus differ in ABO blood type or if the fetus is Rh -positive and the mother is Rh-negative. This erythrocyte incompatibility does not exist in any of the other options. Question 5 ptsThe benefits of buying summaries with Stuvia:
