Buy Water Electrolytes and Diuretics Assignment
1. Which of the following statements best applies to
triamterene?
A. A diuretic agent that produces an increased excre¬
tion of sodium and chloride and a reduced excretion
of potassium (especially in the presence of mineralocorticoids) through a direct action on the kidney
B. Diuresis is related to inhibition of sodium reabsorp¬
tion in the ascending loop of Henle and is effective
in the rat as well as in man
C. A brief-acting aldosterone antagonist that is inde¬
pendent of acid-base balance
D. An agent that produces a diuresis with alkaline urine
and increased potassium and bicarbonate loss
E. A satisfactory chloruretic and natriuretic response
is also accompanied by significant kaluresis and is
independent of acid-base balance

2. Concerning acid-base balance and diuretic therapy
A. carbonic anhydrase inhibitors induce metabolic
alkalosis, which greatly reduce their diuretic effect
B. mercuric diuretics tend to induce hypochloremic
acidosis
C. thiazide diuretics do not affect the acid-base bal¬
ance, but they are ineffective in acidosis
D. furosemide and ethacrynic acid tend to induce hy¬
pokalemia and alkalosis with prolonged use
E. ammonium chloride tends to produce alkalosis
3. Which of the following is true concerning glomerular
filtration?
A. Its filtering force comes from the work of the heart
B. The glomerular efferent vessel is a venule
C. It will cease when mean blood pressure falls below
70 mmHg
D. The most common cause of reduced renal filtration
rate may be corrected by a number of drugs
E. It is commonly measured by the use of PAH
 
4. Undesirable side effects of thiazide diuretics include all
of the following EXCEPT
A. hyperuricemia
B. hyperglycemia
C. reduced renal blood flow (RBF) and glomerular
filtration rate (GFR)
D. potassium retention with excess water loss
E. cholestatic hepatitis

5. All of the following statements about furosemide are
correct EXCEPT
A. it is one of the most potent diuretic drugs
B. its primary effect is inhibiting chloride reabsorption
in the ascending limb of the loop of Henle
C. when given in high doses it may produce metabolic
acidosis because it inhibits H secretion in the distal
tubule
D. it may produce hypovolemic shock secondary to
exaggerated response
E. its use in combination with ethacrynic acid is con¬
traindicated
6. All of the following statements are correct about man¬
nitol EXCEPT
A. it produces diuresis in the presence of reduced
glomerular filtration rate
B. it is filterable and poorly reabsorbed in the renal
tubules
C. it produces very little, if any, disturbance of acidbase balance
D. its site of action is the proximal tubule
E. it is the diuretic of choice to treat chronic pulmon¬
ary edema
295. All of the following mechanisms may be involved in the
pathogenesis of peripheral edema EXCEPT
A. increased activity of the renin-angiotensin-aldoster¬
one system
B. decreased plasma colloid osmotic pressure
C. diminished capillary hydrostatic pressure
D. decreased activity of diuretic-natriuretic systems
E. sodium retention
