Term

Definition
absorption
Term

Definition

1) establish a time line

2) inform the pt of the possible correlations between their medications and symptoms

3) conduct and report all audiometric findings, specifically high frequency HL

4) comment in your report about the symptoms' correlations time line to the referring physician

Term

Aminoglycoside ototoxic effects are usually immediate, within 1 hour

T/F

Definition
False
Term
In many cases, high freq. PT testing should be coupled with DPOAE testing for monitoring pts for early ototoxicity T/F
Definition
True
Term
When counseling a pt about their current medication side effects and their audio/vest complaints, EVERY adverse drug reaction on the list should be reviewed in detail
T/F
Definition
False
Term
A new pt tells you that several months ago he was hospitalized for an infection and received IV antibiotics, which was a mycin drug. To rule out delayed onset or progressive HL, you should monitor his hearing:
Definition

Definition
late onset, more severe in the high frequencies progressive in nature
Term

Definition
False - currently no FDA approved otoprotective agents
Term
Describe risk factors that place pts at greater risk for developing ototoxicity
Definition
Very young or old age, renal issues, noise exposure, use of loop diuretics with other ototoxic drugs, use of aminoglycosides with platinum based drugs, use of vancomycin with aminoglycosides, carboplatin with previous cisplatin treatment, pre-existing HL
