What is the mechanism of action of buprenorphine?

Partial opioid agonist


What happens if buprenorphine is given to someone who is currently high? What about if they are sober?

Will precipitate some withdrawal in someone who is high, will get someone who is sober a little high. Easiest way to think about it - it will bring people to a particular level.


What is in suboxone? Why?

Subuxone is buprenorphine and naloxone. The naloxone if there primarily so people don't crush it up and inject.


What are the three primary treatments for opioid use disorder?

1. Methadone
2. Buprenorphine
3. Naloxone


Why don't people like taking naltrexone?

Have to detoxify before initiating. For this reason, might be particularly good for people initiating right out of prison.


1. What is a simple ECG sign of right axis deviation?
2. In the setting of this previous ECG finding, what additional finding would indicate RVH?
3. What ST-T findings are typical for RVH?

1. Deep S wave in I
2. Large R wave in V1
3. Deep and narrow T wave inversions in V1, V2, and V3 (I think?)


What critical finding does this ECG show?

Terminal QRS distorsion in V3. It is diagnosis o LAD occlusion. TQRSD is defined as the absence of BOTH an S-wave and a J-wave in leads V2 or V3


If a patient has atrial fibrillation and is not on AV nodal blocking medications and has a normal heart rate, what should the concern be?

AV node disease. It is normal in A-fib for a healthy AV node that is not under the influence of meds to transmit beats


What are the typical symptoms of arsenic poisoning?
How are people usually exposed?

Vomiting, diarrhea, abdominal pain, fluid loses to the point of hypotension. Hypersalivate, garlicky odor. Acute encephalopathy, delirium, seizure, coma. Liver failure, renal failure, ARDS, arrhythmia can occur in severe cases. Peripheral neuropathy and pancytopenia develop after the acute illness.

Worldwide, groundwater is the most common exposure. Commercial forms found in pesticides, alloy strengthening materials, paint pigments.


Why is identifying right ventricular MIs important?

1) Higher mortality
2) More likely to be hypotensive
3) Much more nitroglycerin sensitive


1) What is the best was to diagnose right ventricular MI?
2) What is a suboptimal way?

1) Right sided ECG. ST elevation in V4, V5, V6 is indicative of RV MI
2) V1 (thought right sided ECG is way better). If there is no ST depression in V2, then elevation in V1 is relatively specific (~85%) for RV MI. If there is ST depression in V2, then ST depression in V1 is not specific for MI, as there may be a posterior MI also impacting the ST segment in V1


With a pediatric both bone forearm fracture, how should the bone be reduced?

If the periosteum is intact, don't distract the bones, simply realign. If the periosteum is broken, then may need to be distracted.


Bones of the mid and hind foot
4 bones in a row from medial to lateral in the mid foot?
1 bone posterior to that row?
Two bones in the posterior foot?

Medial Cuneiform, Intermediate Cuneiform, Lateral Cuneiform, Cuboid
Navicular is posterior to the cuneiforms (it's medial)
Talus, Calcaneus
