Back 4

Loop Diuretics

Front 5

Loop Diuretics

Back 5

antagonize aldosterone and block reabsorption of chloride and sodium

Front 6

Loop (high-ceiling) diuretics

Back 6

High ceiling diuretics are diuretics that may cause a substantial diuresis - up to 20% of the filtered load of NaCl and water. This is huge, compared to that normal renal sodium reabsorption leaves only ~0.4% of filtered sodium in the urine.

Front 7

synomous with high ceiling diuretics

Back 7

Loop diuretics, such as furosemide, inhibit the body's ability to reabsorb sodium at the ascending loop in the kidney which leads to a retention of water in the urine as water normally follows sodium back into the extracellular fluid (ECF). Other examples of high ceiling loop diuretics include ethacrynic acid, torsemide and bumetanide.

Front 8

Front 10

sulfonamide derivative

Back 10

Loop Diuretics
like the carbonic andydrase inhibitors (CAI'S), loop diuretics are chemicially related to sulfonamide antibiotics

Front 11

Back 11

Loop Diuretics

Front 12

The 1st line of drug for hypertension is___. Most commonly used with an anti-HTN like beta blocker.

Back 12

Thiazide

Front 13

___ is mostly used for edema.

Back 13

Loop diuretic

Front 14

describe the general process of how a loop diuretic works in the body

Back 14

blocks the rebsorption of K+ and NaCl, primiarly Na, and carries H2O molecules with the Na out to the ureturs

Front 15

What is the main nursing diagnosis for the patient on diuretics

Back 15

FVD

Front 16

Loop diuretics as well as carbonic anhydrase inhibitors (CAI'S) are diritives of {what} and therefore should not be given to patients with {what} allergy?

Back 16

{sulfonamide dirivites} and should not be given to patients with {sulfa} allergies

Front 17

Patients on loop diuretics should be checked for {what} electrolyte problem and be given {what} diatery supplement.

Back 17

They should be checked for {hypokalemia} and be given {KCl} supplements.

Front 18

Name three observable symproms to watch for when administering loop diuretics.

Back 18

weakness, passing out, heart irregularities which is the worst problem due to the action of increased pressure in the renal system and decreased pressure in the vascular system (heart, lungs, peripheral vascular sys. and central veins)

Front 19

lasix is what kind of drug

Back 19

a loop diuretic

Front 20

loop diuretic works on what part of the renal system

Back 20

the ascending loop of Henle

Front 21

what OTC has the opposite effect on prostaglandin activity in the diuretic family of drugs and what is the classification of those drugs

Back 21

NSAID's have the opposite effect on vascular resistance reduction from Loop diuretics

Front 22

What common problem is assiciated with administration of loop diuretics with digoxin?

Back 22

dig toxicity: common in patients with low potassium levels (hypokalemia) as can occur with loop diuretics, since digoxin normally competes with K+ ions

Front 23

rapid injection os lasix may lead to what problem?

Back 23

ototoxiciy resulting in hearing loss which is reversible

Front 24

expected outcome of lasix

Back 24

increased diuresis, decreased b/p

Front 25

what is the main function in the kidneys of potassium-sparing diuretics

Back 25

block aldosterone receptors so you loose Na in the urine

Front 26

main side effect of spironolactone

Back 26

hyperkalemia

Front 27

inhibits the resorption of Na, Cl, and K, and decrease preload (filling pressures) and afterload (the force the heart must over come to eject the blood)

Back 27

thiazide and thiazide-like diuretics

Front 28

lab value for hyperkelemia

Back 28

serum potassium level greater than 5.5 mEq/L

Front 29

common adverse effects to watch for with thizaide-like diuretics

Back 29

dizziness and vertigo, due to sudden shifts in plasma volume from drug therapy, nursing intervention is to check b/p lying, sitting and standing (maybe before you ambulate pt. let their b/p returne to baseline)

Front 30

Nursing Interventions for administering diuretics

Back 30

give in AM to prevemt sleep disturbance ie. falling during nocturia
check s/s for hypovolemia: low b/p, dizziness
s/s hyperkalemia: tachycardia, cardiac arrest!!
exacerbation of diabeties: increase sugar concentration due to fluid loss

Front 31

foods high in K

Back 31

bannanas, fresh vegetables, potatoes (white and sweet), cantelopes, oranges, dates, rasins, meat, fish, apricots, whole grain cereals, legumes (so basically don't eat if on potasium sparing diuretics!!)
