loop diuretics

- dehydration
- hypotension
- hypovolemia
What adverse effects are associated with loop diuretics?
- ototoxicity: tinitus, vertigo, nausea
- hyperglycemia
- hyperuricemia
- increased LDL and decreased HDL
What are some nursing interventions for loop diuretics?
- obtain baseline data: vitals, i's&o's, amount and placement of edema, lung sounds,

- carbamazepine and thiazide diuretics increase each-other's toxicity
What are the food interactions associated with thiazide diuretics?
- ginko biloba may cause paradoxical interaction and cause HTN
