no- probably not but maybe if medication not changed in 5 years and hasnt seen physician in a while -- then we would have a problem with that
26
55 y/o male with PMH of MI 3 years ago, presents with pain on #32 Meds= tropol (beta-blocker), lipitor Linisopril (ace-inhbitor) aspirin 81 mg allergies = NKDA PSH - tonsillectomy SH- denies tob or ETOH physical exam - large decay below gingival margin, tooth non-restorable and needs surgical extraction comfortable doing procedure? what questions do you ask?

technique= inferior alveolar + long buccal marcaine or bepivicaine limit on cardiac pt. is 0.04 mg
28
if pt. described also had a history of congestive heart failure are there any contraindications to the use of local anesthetics?
relative contraindication - as heart is not pumping as strong but can still use
29
why would patient feel discomfort even after giving an IANB and shows signs of being numb?
1. no buccal nerve block 2. ACCESSORY SENSORY INNERVATION -- from nerve to mylohyoid 3. missed the block - too low - too anterior
30
what post op pain medication would you prescribe for following surgical extraction?
if need opoid -- okay to prescribe but need to know for how long pain relief will be required

APAP - acetomitophen NSAIDS
35
motrin =
ibuprofen = advil
36
motrin effects?
produces anti-inflammatory, analgesis, and antipyretic (fever) effects by inhibiting prostaglandin synthesis
37
max daily dosage of motrin?
do not exceed 3.2 mg in a 24 hour period
38
motrin drug interactions with antihypertensives?
may decrease the effectiveness
39
motrin drug interactions with ASA or corticosteroids?
ASA (aspirin) and corticosteroids -- could increase the risk of adverse GI effects
40
motrin drug interactions with oral anticoagulants?
may increase the plasma levels or effects of these medications
41
motrin drug interactions with methotrexate?
decreased clearance -- thus increased toxicity
42
adverse motrin effects on CNS and CV?
CNS -- HA, dizziness CV- fluid retention, edema
43
adverse motrin effects on GI? GU?
GI= peptic ulceration GU= acute renal failure
44
adverse motrin effects on hematology? hepatic? respiratory?
hematologic -- prolonged bleeding time hepatic -- elevated liver enzymes respiratory -- bronchospasm
45
example rx for motrin?
Motrin 600 mg Disp: #15 (fifteen) Sig: one tab q 6 hrs prn pain refills: none
46
acetominophen action?
thought to produce analgesia by blocking generation of pain implses, probably by inhibiting prostaglandin synthesis in the CNS or the sybthesis or action of other substances that sensitize pain receptors to mechanical or chemical stimulation thought to relieve fever by central action in the hypothalamic heat regulating center effective in analgesic effects with antipyretic effects but LITTLE ANTI-INFLAMMATORY activity APAP may function by inactivating COX enzymes responsible for the final catalytic reaction
47
dosage for adult for acetaminophen?
325 to 650 mg P.O. every 4 to 6 hours; or 1 g P.O. three times a day as needed
48
acetaminophen hepatic toxicity reached when? FDA request that dose of APAP contained in prescription opiod APAP analgesics be limited to max what?
when daily dose of 4000 mg is exceeded prescription opoid APAP max = 325 mg ( so no more than 325 per capsule) and with continued concern tylenol manufacturer reduced max daily recommendation from 4000 to 3000mg
49
rx for one week of amoxicillin
Rx: amoxicillin 500 mg Dis : 21 (twenty-one) capsules Sig: one capsule P.O. tid until completed Refills : none
50
dosage for amoxicillin adult
250-500 mg P.O every 8 hours
51
amoxicillin action
an aminopenicillin that inhibits cell-wall synthesis during bacterial multiplication
52
how do bacteria resist amoxicillin?
by producing penicillinases (enzymes that hydrolyze amoxicillin)
53
amoxicillin adverse reactions in CNS
lethargy, hallucinations, seizures, anxiety, confusion, agitation, depression, dizziness, fatigue
54
amoxicillin adverse reactions in GI
Nauseau, vomitting, diarrhea, glossitis, gastritis, abdominal pain, PSEUDOMEBRANOUS COLITIS , entercoloitis *can develop c-dif
55
most side effects of amoxicillin occur where?
GI
56
two adverse drxns to amoxicillin need to be aware of in prescribing
1. anaphylaxis | 2. overgrowth of nonsusceptible organism
57
major concern with prescribing opoid analgesiscs in terms of adverse side effects
respiratory depression can also cause sedation, euphoria, cough supression, constipation, miosis
58
what type of analgesic used- general
full agonsist with minimal first pass effect -- so more available to tx pain and also will include a non-opoid analgesisc as component of formula to provide added analgesia
59
comparative oral dosing equivalents in opioid analgesics
5mg of oxycodone = 10 mg of hydrocodone = 65 mg of codeine= 75 mg of tramadol
60
oxycodone aka
percaset
61
hydrocodone aka
vicodine
62
tylenol #3 has?
acetaminophen 300 mg and codeine phosphate 30 mg
63
opiod administers effect how?
binds with opiate receptors in the CNS, altering both perception and emotional response to pain through unknown mechanism also depresses the cough reflex by direct action on the cough center in the medulla
64
adult opiod dosage
15 to 60 mg P.O. every 4-6 hours as needed for pain
65
which is rate limiting for dosage between non opoid analgesis and opiod?
non -opoid so if 24 hour period can max out at 3000 mg and combo is 300 mg acetaminophen with 30 mg of codeine phospate ***so can give 10 total
66
drug interactions with opiods?
CNS depressants -- can all have addative effects
67

68
percocet composition?
``` acetaminophen = 325 mg oxycodone = 5mg ```

Rx: Percocet 5/325 Disp: #12 (twelve) Sig: one tablet P.O. q 6hrs. prn pain refills: none
70
