NBDE II - questions discussions

[Life9]

Hi Everybody.

I am planning to take the NBDE II exam. Wanted to discuss some questions. Hopefully thru this we can help each other out.

Lets start:

Q1. Which antibiotic combination has the widest spectrum?
- Amoxicillin + clavulanic acid
- Pen V + tetracycline
- Amoxicillin + Metronidazole
- Erythromyicn + Tetracycline

- Pen V + tetracycline
- Amoxicillin + Metronidazole
- Erythromyicn + Tetracycline

i think its amoxicillin + clavulinic acid

 

[Life9]

i think its amoxicillin + clavulinic acid

Thank You Hydhaval for replying. i think that as well but what about metronidazole and amoxicillin?...does that not also has wide spectrum as well.

 

[aim high]

even i think that its amoxicillin + clavulinic acid i.e AUGMENTIN ..it is a broad spectrum antibiotic which even reduces development of drug resistant becteria.

correct me if iam wrong

correct me if iam wrong

Ok..augmentin is a broad spectrum antib with activity against gram - and +....BUT not anaerobios. Metronidazol is for anaerobic bacterias, and spirokettas (sorry with my writting, english is not my tongue)


SO.....the correct answer is Amoxicilina+ Metronidazol, because is indicated against P. gingivalis and A. Actinomycetemcomit... in Adult and Refractar Periodontitis.

 

[Rissas]

Please help me!!!

Syndrome that exhibits NO clinical manifestation and is usually detected only upon routine RX examination is:

a) Gardner Synd
b)Aschers Synd
c) Eagle Syndrom
d) Median Cleft Face Synd

I thought the C was the correct but is D, ....WHY??????

 

[Life9]

Thank Rissas

I tried to search for asnwer to your question, the only thing i can think of is that Median Cleft Face Synd is from birth and the other options are not.


More questions:
Patient has asthma, uses ventolin and betamethasone. best pain med.
- ASA
- Duflonasal
- Ibuprofen
- T3
- Naproxen

Pt. with diabetes I develops severe odontogenic infection with systemic symptoms. Which antibiotic to give?
- Erythromycin
-Cephalexin
-Pen V
-Pen V+ Metronidazole
-Clindamycin

 

[Rissas]

Thank Rissas

More questions:
Patient has asthma, uses ventolin and betamethasone. best pain med.
- ASA. contraind in asma
- Diflunisal. Contraind
- Ibuprofen. contraind in asma
- T3. I dont know what this mean???
- Naproxen. Almost the same to Ibuprof
I dont see the ans....

Pt. with diabetes I develops severe odontogenic infection with systemic symptoms. Which antibiotic to give?
- Erythromycin. Not use
-Cephalexin. Only for Gram +
-Pen V Oral
-Pen V+ Metronidazole. Pen V is a soft drug (oral), and Metronid has wide spectrum. And in this patient the origin of infection was probably periodontal (anaerobic bacteria)....This means that this combination for This kind of patient is the best.
-Clindamycin

Because the infection is severe we should prefer IV drugs. It can be Pen V oral(for Cocos gram+, gram-) and Metronidazol(IM) because has a wide spectr, for anaerobic bacillus gram-, and ,actinomicetemcomitans...Pen V +metronidazol is a better choice

T3 i meant Tyneol 3. i think that is the answer.

PLease help another
question:

In a standard inferior alveolar nerve block, which
muscle is penetrated by the needle?
A. Buccinator.---i think this might be the answer, please correct me if i am wrong. http://www.drchetan.com/inferior-alveolar-nerve-block.html
B. Mylohyoid.
C. Superior constrictor.
D. Masseter.
E. Medial (internal) pterygoid.

I think E ( medial pterygoid )is the answer ,the needle lies lateral to medial pterygoid muscle during inf alv nerve block.

 

[Life9]

I think E ( medial pterygoid )is the answer ,the needle lies lateral to medial pterygoid muscle during inf alv nerve block.

Thank you for your help. does it not go thru the buccinator muscle?

question:
Pain to hot lasting more than 10 min. is charaterstic:
-necrotic tooth
-pulp polyp
-pulpal hyeraemia
-late irreversible pulpitis

Porcelain fractured at metal/proclain interface on MC bridge most probably due to:
-flexure of the bridge
-porosity of porcelain
-contamination of porcelain surface before procelain baking

What causes the most damage to an opposing restoration?


Overdenture
Complete Denture
Tooth-support RPD

[hydhaval]

hey nbde2, thank you very much

 

[aim high]

What causes the most damage to an opposing restoration?


Overdenture
Complete Denture
Tooth-support RPD
Tooth-tissue RPD---answer ( this not a very stable RPD with a immovable natural teeth support and a movable denture bearing tissues support because of which there is possible damage to opposing restoration)

correct me if I am wrong

[Cold Front]

how to calculate?

using B speed film exposure to patient at 3 feet is 1 R. What would be the exposure be with D speed film at 6 feet?

ans is 1/8 R??

I started reviewing NBDE 2 stuff earlier today, so I will take a bite at this.

First of all, do the numbers for the B speed film using the Inverse Square Law.

Original Intensity/New Intensity = New Distance Squared / Original Distance Squared

So... 1 / x = 6 squared / 3 squared

find x (for new exposure or new intensity or R)

x = 1/4 (this is R assuming if the film speed was still B)

D speed films are faster and more sensitive than B by half, so the exposure conversion will be 1/2 x whatever B is. So 1/2 * 1/4 = 1/8.

I hope I am right~

yes,i think that you can say both spenopalatine fossa or pterygopalatine fossa are correct. ..but more appropriate answer would be pterygo palatine fossa.

In mand nerve block ,the solution is deposited near the mand foramen... i dont think we deposit it into infratemporal fossa as it is a space behind the maxilla.
