2.
Which of the following is NOT true, regarding loop diuretics?
Correct Answer
A. Loop diuretics decrease absorption in the distal tubule.
Explanation
Loop diuretics inhibit sodium and chloride reabsorption in the ascending loop of Henle, and promote the excretion of sodium, chloride, potassium and water. They can cause dehydration. THIAZIDE diuretics decrease absorption in the distal tubule.

3.
Which of the following is NOT a loop diuretic?
Correct Answer
D. Chlorothiazide (Diuril)
Explanation
Loop diuretics include Furosemide (Lasix), Bumetadine (Bumex), Torsemide (Demadex) and Ethacrynic acid (Edecrin). Chlorothiazide (Diuril) is a thiazide diuretic.

4.
Which of the following is NOT true, regarding thiazide diuretics?
Correct Answer
C. They inhibit the sodium-potassium exchange in the distal tubule.
Explanation
Thiazide diuretics promote the excretion of sodium, chloride, potassium and water by decreasing absorption in the distal tubule. They can cause orthostatic hypotension. POTASSIUM-SPARING diuretics inhibit the sodium-potassium exchange in the distal tubule.

5.
Which of the following is NOT a thiazide diuretic?
Correct Answer
D. Triamterene (Dyrenium)
Explanation
Thiazide diuretics include: Bendroflumethazide (Naturetin), Chlorothiazide (Diuril), Hydrochlorothiazide (HCTZ), Metolazone (Zaroxolyn), Polythiazide (Renese), Chlorthalidone (Hygroton), Trichlormethiazide (Naqua), Indapamide (Lozol), and Xipamid (Xipamide). Triamterene is a potassium-sparing diuretic. LeMone, P., Burke, K., & Bauldoff, G. (2011). Medical-Surgical Nursing: Critical Thinking in Patient Care, 5th ed., San Francisco: Pearson. p.199
6.
Which of the following is NOT a potassium-sparing diuretic?
Correct Answer
D. Torsemide (Demadex)
Explanation
Potassium-sparing diuretics include: Spirinolactone (Aldactone), Amiloride HCL (Midamor), and Triamterene (Dyrenium). Torsemide is a loop diuretic.

7.
To reduce fall risk, which of the following suggestions should be given to the patient, regarding their diuretic?
Correct Answer
B. Take the drug in the morning.
Explanation
Diuretics should be taken only in the morning (when possible), to reduce fall risks - people get up during the night to void, and are more apt to fall at that time. Doses should never be halved or skipped when the patient is ill - and they need to weigh themselves daily.

8.
Which of the following should NOT be used by a patient taking Aldactone (Spironolactone)?
Correct Answer
C. Salt substitute
Explanation
Salt substitutes contain potassium. Aldactone is a potassium-sparing diuretic, so it might cause a higher potassium level.

9.
People using loop diuretics or thiazide diuretics are NOT at higher risk for which of the following?
Correct Answer
D. Elevated potassium
Explanation
Loop and thiazide diuretics can cause low potassium, PVCs, and Digoxin toxicity.
