it is not metabolically metabolised

152

1l

154

A

200ml/10h

159
Q

extra fluids and mannitol prevent damage to what organ in patients that are on cisplatin

A

kidney

160
Q

the risk of ototox exists with cisplatin, however, it can cannot be prevented. what should patients be aware of reporting if it develops

A

tinnitus or hearing loss

161
Q

how can nephrotoxicity when on cisplatin be prevented

A

good hydration and ensuring good kidney function at start

162
Q

there is not much that can be done about neurotoxicity in patients that are on cisplatin, however what warning signs should be reported by patients

A

numbness in fingertips, hands or feet

163
Q

why is a fbc necessary for cisplatin
what parameters are important

A

vinca alkaloids

166
Q

why might uric acid levels be raised in haematological cancers especially

A

risk of tumour lysis syndrome TLS

167
Q

what is extravasation

A

drugs leak outside of vein and damage surrounding tissue

168
Q

true or false, vessicants cause the most damage if extravasated

A

true

169
Q

if the drug that extravasates is a vesicant what should the next steps be

A

stop drug and leave cannula in place

170
Q

why would you initially leave the cannula in place in case of extravasation

A

aspirate as much drug as possible

171
Q

what should be marked on the patient after extravasation

A

area of damage

172
Q

what specific antidote may be given for anthracyclines that extravasate

A

dexrazoxane
chemo drug, free radical scavenger

173
Q

for anthracyclines would you use a warm or cold pack

A

cold

174
Q

why would a cold pack be used for anthracyclines

A

want to localise drug and prevent it spreading

175
Q

would vinca alkaloid extravasation require a warm or cold pack

A

warm

176
Q

why would vinca alkaloids require a warm pack

A

no antidote so want to disperse through the tissue

177
Q

A

hyaluronidase
