What is osmolality

A

The strength or concentration of the urine produced

3

What drugs are used in treating fluid overload or edema

A

Diuretics

6
Q

What conditions does diuretics treat

A
Chronic heart failure
Pulmonary edema
HTN
Cirrhosis ( liver failure)
Nephrotic syndrome
Kidney failure
7
Q

What is the prototype drug of thiazide diuretics

A

Hydorchlorothiazide ( HydroDIURIL)

8
Q

What are thiazide diuretics used for

A

In the treatment of hypertension

9
Q

Where does thiazide diuretics work

A

In the distal tubule

10
Q

What are contraindications and precautions of thiazide diuretics

A

Severe renal impairment
Anuria
Hepatic coma
Hypersensitivity

11
Q

What are adverse effects of thiazide diuretics

A
Hypokalemia 
Hyponatremia 
Hypochloremia
Hypomagnesemia
HYPERCALCEMIA
12
Q

What drug does thiazide diuretics interact with

A

Digoxin

13
Q

With any diuretic what should you monitor for

A

Hypokalemia

14
Q

What is a contraindication to thiazide diuretics

A

Sulfa

15
Q

What are signs and symptoms of hypokalemia

A

Arrhythmias

16
Q

What is a sign of hyponatremia

A

The body craving salt

17
Q

Hydrochlorothiazide is more effect in what ethnic group

A

African Americans

18
Q

What is a loop diuretic

A

They excerpt a powerful effect on fluid and electrolyte balance
They work in the loop of henle to inhibit sodium and chloride

19
Q

What are loop diuretic used for

A

Pulmonary edema
CHF
Peripheral edema
it depletes K+ very fast

20
Q

What is the prototype drug of loop diuretics

A

Furosemide ( lasix)

21
Q

How are loop diuretics administered

A

IV or oral

Excreted in the kidneys

22
Q

What are adverse effects of loop diuretics

A

Electrolyte imbalance
Ototoxicity if pushed too fast
Alteration in blood glucose levels
Alecia man

23
Q

What 2 drugs shouldn’t be given concurrently with loop diuretics

A

Digoxin

Aminoglycosides

24
Q

How long should one push furosemide

A

20-40 mg over 1-2 minutes

Closely monitor potassium levels

25
Q

What labs should be monitored with furosemide

A

CBC
SERUM ELECTROLYTE
URIC ACID LEVELS

26
Q

Wh would a pt who is malnourished be at greater risk for toxicity from furosemide

A

Because the malnourished pt has less protein in the body which will result in more free drug. Furosemide is a highly protein bound drug

27
Q

Potassium sparing diuretics prototype drug

A

Triamterene ( Dyremium)

28
Q

What are potassium sparing diuretics used for

A

It is used as an adjunct to manage edema and HTN

29

Hyperkalemia
Nephrotoxic it's
Thrombocytopenia 
Elevated liver enzymes
Headache
Photosensitivity
31

What lab level indicates thrombocytopenia

A

Platelet count less than 50,000

32
Q

What are normal platelet counts

A

150,000-450,000

33
Q

What are osmotic diuretics used for

A

They are used for intracranial pressure
& pushes fluid back into vascular space
Cerebral edema
And reduces intraocular pressure

It causes a severe electrolyte imbalance it is a very strong diuretic
