Question 1

Which one of the following medications is a loop diuretic?

Accepted Answer

Lasix is classified as a loop diuretic.

Question 2

Minerals made up of electrically charged particles held together by ionic bonds in the body are called

Accepted Answer

Electrolytes are minerals made up of electrically charged particles held together by ionic bonds.

Question 3

Hydrochlorothiazide (HydroDIURIL)is which type of diuretic medication?

Accepted Answer

HydroDIURIL is classified as a thiazide diuretic.

Question 4

Potassium-sparing diuretics are commonly used to treat which one of the following conditions?

Accepted Answer

An indication for potassium-sparing diuretics,which are low in potency,is to treat edema.

Question 5

Which electrolyte may be seriously depleted in patients taking certain diuretics?

Accepted Answer

Most diuretics cause the excretion of electrolytes other than sodium,including potassium.Because normal serum potassium levels are narrow (3.5 to 5.0 mEq/L),a depletion of potassium levels can result.

Question 6

What cardiac condition requires treatment with diuretics?

Accepted Answer

Congestive heart failure is the result of the heart's inability to pump blood and the resultant back pressure of blood that slows the venous blood.When the right ventricle fails,congestion of the organs and extremities will result.Diuretic medications assist the body in removing the excess fluid,which helps decrease this congestion.

Question 7

The trade,or brand name,for furosemide is

Accepted Answer

The brand name for furosemide is Lasix.

Question 8

Which one of the following types of diuretic medications is prescribed in the treatment of glaucoma?

Accepted Answer

Carbonic anhydrase inhibitors are active in the formation of aqueous humor in the eye.By inhibiting the production of aqueous humor,these drugs lower the intraocular pressure that causes glaucoma.

Question 9

The definition of a diuretic medication is an agent that prevents the reabsorption of sodium and water by which one of the following organs?

Accepted Answer

The definition of a diuretic medication is an agent that prevents the reabsorption of sodium and water by the kidneys.

Question 10

The diuretic medication that draws fluid out of tissues and into the circulatory system is called

Accepted Answer

The definition of an osmotic diuretic is an agent that draws fluid out of tissues and into the circulatory system.The result is an increase of blood pressure and volume levels.

Question 11

How are electrolytes acquired?

Accepted Answer

Electrolytes are obtained through food and water.

Question 12

Which one of the following conditions is not a result of hypokalemia?

Accepted Answer

Low serum potassium does not cause increased intracranial pressure.

Question 13

Diuretics cause the elimination of excess fluid by preventing the reabsorption of which one of the following elements?

Accepted Answer

The mechanism of a diuretic medication is to prevent the reabsorption of sodium and,consequently,water by the kidneys; thus the increased elimination of fluids results.

Question 14

The only diuretic administered from the sterile back table is

Accepted Answer

Mannitol,which is contained in the ophthalmic medication Miochol-E,is given from the back table.

Question 15

Which term indicates an abnormally high concentration of potassium in the blood?

Accepted Answer

The definition of hyperkalemia is an abnormally high potassium concentration in the blood.

Question 16

Which diuretic is contraindicated in patients with hypertension?

Accepted Answer

Osmotic diuretics actually increase blood pressure by drawing fluids from tissues and into the circulatory system.

Question 17

Which one of the following is classified as a high-ceiling diuretic medication and is used to decrease intracranial pressure?

Accepted Answer

Lasix decreases intracranial pressure by quickly removing fluid that accumulates in response to the trauma of intracranial procedures or injuries.It works by decreasing the reabsorption of sodium and chloride ions along the renal tubule.

Question 18

What is the normal range for serum potassium?

Accepted Answer

The normal range of serum potassium is 3.5 to 5.0 mEq/L.

Question 19

When too much potassium is excreted,the resulting condition is called

Accepted Answer

The definition of hypokalemia is low serum potassium levels.

Question 20

The trade,or brand name,for mannitol is

Accepted Answer

The brand name for mannitol is Osmitrol.
