1
Q
Naloxone reverses _____

5. Hydromorphone

- Midazolam
- Diazepam
- Rapid acting after IV administration

4
Q
Edrophonium reverses ____
A
- non-depolarizing muscle relaxants (anticholinesterase inhibitor) - Atracurium
5
Q

6
Q
Neostigmine reverses ______
A
- competitive, nondepolarizing neuromuscular blocking agents like atracurium
7
Q
Yohimbine reverses _____
A
- xylazine
- detomidine
- Antagonizes alpha-2 agonist effects (useful for reversing excessive sedation
from high doses of xylazine or detomidine).
- It is not a specific alpha-2 antagonist, has a slow onset of action, and does
not reliably antagonize alpha-2 agonist
