Question 1
pts
The lung is innervated by the parasympathetic nervous system via which nerve?
Vagus
Phrenic
Brachial
Pectoral
Fibers of the parasympathetic division of the autonomic nervous system (ANS) travel
only in the vagus nerve to the lung.
Question 2
pts
What is the action of urodilatin?
Urodilatin causes vasoconstriction of afferent arterioles.
It causes vasodilation of the efferent arterioles.
Urodilatin inhibits antidiuretic hormone secretion.
https://www.stuvia.com/en-us/user/MBoffin
,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
theactions described by the other options.
Question 3
pts
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 water
absorptionby kidney tubules. The other actions are not a result of the atrial natriuretic
hormone.
Question 4
pts
Which statement best describes a Schilling test?
https://www.stuvia.com/en-us/user/MBoffin
, Administration of radioactive cobalamin and the measurement of its excretion in
theurine to test for vitamin B deficiency
12
Measurement of antigen-antibody immune complexes in the blood to test for
hemolyticanemia
Measurement of serum ferritin and total iron-binding capacity in the blood to test for
irondeficiency anemia
Administration of folate and measurement in 2 hours of its level in a blood sample
totest for folic acid deficiency anemia.
The Schilling test indirectly evaluates vitamin B12 absorption by administering
radioactive B12 and measuring excretion in the urine. This selection is the only option
that accurately describes a Schilling test.
Question 5
pts
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
maternalerythrocytes. Maternal-fetal incompatibility exists only if the mother and
fetus differ inABO 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.
