Question 1 of 5
Calculate the net filtration pressure (NFP) with a capillary hydrostatic pressure (CHP) of 20 mm Hg and a blood colloid oncotic pressure (BCOP) of 25 mm Hg. Then determine if filtration or reabsorption occurs.
Correct Answer: D
Rationale: NFP = CHP - BCOP = 20 - 25 = -5 mm Hg; negative NFP means reabsorption.
Question 2 of 5
Which hormone plays a central role in determining the rate of sodium reabsorption and potassium secretion?
Correct Answer: B
Rationale: Aldosterone increases Na+ reabsorption and K+ secretion in distal nephron.
Question 3 of 5
Administration of a cholinergic agent produce a mild contraction of the esophagus in achalaisa
Correct Answer: A
Rationale: Cholinergic agents stimulate acetylcholine receptors, which can cause mild esophageal contraction in achalasia due to increased smooth muscle activity, though the lower esophageal sphincter remains dysfunctional.
Question 4 of 5
Assays of plasma gastrin levels are used for diagnosis
Correct Answer: A
Rationale: Elevated plasma gastrin levels are a key diagnostic marker for Zollinger-Ellison syndrome, reflecting gastrinoma activity.
Question 5 of 5
Fatty liver occurs in:
Correct Answer: D
Rationale: Fatty liver is associated with late pregnancy (acute fatty liver), tetracycline toxicity, obesity, diabetes (nonalcoholic fatty liver disease), and Reye's syndrome (microvesicular steatosis).
