Question 1
pts
The lung is innervated by the parasympathetic nervous system via which nerve?
Vagus
Phrenic
Page 1 of 43
,2
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.
It inhibits salt and water reabsorption.
Page 2 of 43
,3
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.
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 absorption
by kidney tubules. The other actions are not a result of the atrial natriuretic hormone.

Question 4
pts
Which statement best describes a Schilling test?
Administration of radioactive cobalamin and the measurement of its excretion in the urine
to test for vitamin B deficiency
12
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 hours of its level in a blood sample to test
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
