Q

A general acid catalysis is made of a ?

A

weak acid and a conjugate base

17
Q

Roux-en-Y

A

gastric bypass the decreases stomach size and length of intestines, and results in significant weight loss

18
Q

Fentanyl Patch

A

controlled release mechanism with topical application
great alternative for long-acting pain management in end of life care
ensure to rotate site of patch application
do not use near heating pads/blankets

19
Q

Why does the Deposit-Provera injection work?

A

microcrystal suspension has low solubility which allows the drug to be slowly released over several months

20
Q

Nuvaring

A

vaginal ring that allows for lower doses, steady drug levels, and less frequent administration

left in vagina for 3 weeks.

21
Q

Pediatric dosage forms

A

chewable tablets - not for <2 years old
oral liquids- more than 2.5 mL difficult to administer
ODT- must be small and have neutral taste

22
Q

Stimulus causes sodium influx which causes an?

A

action potential

23
Q

Aromatic rings improve what kind of solubility that affects potency?

24
Q

lower pKa means a x proportion of the medication in a lipophilic tertiary state can penetrate into the nerve

25
Amide or ester linkage relate to
metabolism
26
Higher affinity for protein binding correlates with a ?
longer duration of action
27
MOA
blocks both the initiation and conduction of nerve impulses by decreasing the neuronal membrane’s permeability to sodium ions results in inhibition of depolarization with resultant blockade of conduction
28
Most anesthetics are marketed in a solution with a pH of ?
5-7
29
Why do we not use multi dose vials for spinal anesthesia?
preservative in them may cause osmotic changes, swelling, and damage to spinal cord
30
vasoconstrictors will decrease
blood flow
31
Bupivacain liposomal 1.3% suspension
colloidal preparation lasts up to 72 hours cannot contact antiseptics should be administered no sooner than after 20 minutes after the injection of lidocaine
32
IV injection of topi vaccine or bupivacaine can lead to ?
seizures, severe cardiac arrhythmias, cardiac arrest, or death
33
exogenous lipids provide an alternative source of binding known as ?
the lipid sink effect
34
What are good predictors of success when using lipid therapy?
high lipid partition constant and large volumes of distribution
