NR 507 MIDTERM EXAM 2023 / NR 507 WEEK 4 MIDTERM
ADVANCED PATHOPHYSIOLOGY MIDTERM EXAM QUWESTIONS
AND CORRECT VERIFIED ANSWERS
Question 1
- / 2 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
- / 2 pts
What is the action of urodilatin?
Urodilatin causes vasoconstriction of afferent arterioles.
- / 4
It causes vasodilation of the efferent arterioles.
Urodilatin inhibits antidiuretic hormone secretion. 2 / 4
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.
Question 3
- / 2 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
- / 2 pts
Which statement best describes a Schilling test?
