When describing the different classes of diuretics, the nursing instructor would include which of the following as sulfonamides, with nonbacteriostatic action, that inhibit the enzyme carbonic anhydrase? Select all that apply.
Correct Answer: B,D
Rationale: Acetazolamide and methazolamide are carbonic anhydrase inhibitors. Furosemide and torsemide are loop diuretics. Hydrochlorothiazide is a thiazide diuretic.
Question 2 of 5
A nurse is administering acetazolamide to a client. The nurse understands that this drug leads to excretion of which of the following? Select all that apply.
Correct Answer: A,C,D
Rationale: Carbonic anhydrase inhibitors, like acetazolamide, result in the excretion of sodium, potassium, bicarbonate, and water.
Question 3 of 5
A nurse is administering a diuretic that inhibits reabsorption of sodium and chloride ions in the distal and proximal tubules and in the loop of Henle. Which of the following might the nurse be administering? Select all that apply.
Correct Answer: B,C
Rationale: Loop diuretics, like furosemide (Lasix) and bumetanide (Bumex), cause diuresis by inhibiting reabsorption of sodium and chloride ions in the distal and proximal tubules and in the loop of Henle.
Question 4 of 5
After teaching a group of nursing students about diuretics, the instructor determines that the teaching was successful when the students identify which of the following as causing diuresis by increasing the density of filtrate in the glomerulus? Select all that apply.
Correct Answer: D,E
Rationale: Osmotic diuretics, like mannitol and urea, cause diuresis by increasing the density of the filtrate in the glomerulus.
Question 5 of 5
