Answer to Question 1

B
Feedback:
These drugs are freely filtered at the renal glomerulus, poorly reabsorbed by the renal tubule, not secreted by the tubule, and resistant to metabolism. Therefore, options A, C, and D are not correct.

Answer to Question 2

C
Feedback:
Mannitol is an osmotic diuretic. Spironolactone is a potassium sparing diuretic. Bumetanide and ethacrynic are loop diuretics.
