Diuretics Flashcards
1
Q
Diuretics
A
- Affect the metabolic acid-base balance in the body
- Prevent sodium reabsorption, which also prevents water reabsorption → increases water excretion in urine
- Water loss from diuretics may cause acid-base imbalances like metabolic alkalosis
- Remember that pH is directly proportional to HCO3
2
Q
Cardiopulmonary issues from excess fluid caused by
A
- Congestive heart failure (CHF)
- ARDS
- hemodynamic instability
- trauma
3
