2. Diazide
22
Q
Diuretic Uses
A
- Hypertension
- Hyperkalemia
- CHF
- Fluid Overload
- Primary Aldosteronism
23
Q
Diuretic Contraindications
A
- Electrolyte depletion (especially potassium)
- Pregnancy
- Anuria or progressive oliguria
- Anuria is <400 ml/24hr - Hypokalemia (Loop and thiazide) (check lab electrolytes)
- Hyperkalemia (w/ K+ sparing)
- Renal dysfunction
24
Q
Prednisone (glucocorticoid)
-Interaction
A
Prednisone decreases potassium
Also can decrease calcium and magnesium
25
Hypokalemia and Digoxin
Hypokalemia can cause digoxin toxicity
26
Hyperkalemia and ACE inhibitor & ARB
don't give together.
27
Diuretic
| -Drug interactions
1. ACE Inhibitors
2. NSAID's
- Can decrease the effectiveness of diuretics and ACE inhibitors
3. Digoxin Toxicity (with hypokalemia)
4. Corticosteroids (K will decrease)
28
Digoxin Toxicity
| -Signs
1. Light halo's
2. Visual disturbances
3. Severe N/V
29
Diuretics
| -Adverse Effects

2. Electrolyte Imbalance
3. Hearing Changes (LASIX) **TEXT
4. Photosensitivity (hydrochlorothyozide) --turns urine blue **TEST
5. Dehydration -- If BUN is high but everything is normal cut back on diuretics.

| -Implications
Limit Sun Exposure
33

| -How fast does it work?
1. 5 minutes to take effect
34

| -How to know they are working
1. Lowered BP
2. Potassium levels are good
3. CHF is good
4. They are urinating

46
Potassium
| -can it be given IV push?
potassium cannot be given IV push.
