Term
| How would you know if an IV solution can be given peripherally or centrally? |
|
Definition
According to the tonicity
Peripheral max 900mOsm |
|
|
Term
| If a patient was hypotensive which IV fluid would be given and why? NSS or D5W or LR |
|
Definition
NSS of LR would be given because it expands the ECF volume to 19 L whereas D5W is 17L.
