I just took this quiz on rabies. It's quite interesting.

How many can you get right?

5. The rabies virus affects both wild and domestic animals, with the added risk that certain mammals are more contagious with the rabies virus than others. The animal that is less likely to transmit rabies to humans is the:
A. Bat.
B. Dog.
C. Fox.
D. Racoon.
E. Squirrel.

6. In African countries such as Ethiopia, in contrast to the United States, the most likely animal to transmit rabies to humans is the:
A. Bat.
B. Dog.
C. Fox.
D. Hyena.
E. Skunk.

7. The incubation period after exposure to a rabies-infected animal varies, but shorter incubation periods are more often seen in a(n):
A. Adult.
B. Bat aerosol exposure.
C. Face bite.
D. Finger bite.
E. Leg bite.

8. The best test to confirm a diagnosis of rabies earliest in a suspected human rabies case is a(n):
A. Cerebrospinal fluid rabies antibody test.
B. Computed tomography scan of the brain.
C. Direct fluorescent antibody test of the saliva for rabies-specific antigen.
D. Electroencephalogram.
E. Reverse transcriptase-polymerase chain reaction test of the saliva for rabies antigen.

9. A 5-year-old boy is playing in his backyard when he encounters a raccoon, which bites him on his hand. The animal escapes, and the child is brought to the emergency department for treatment. The wound is cleaned with 20% soap and povidone-iodine solution. The best next course of action is to:
A. Administer one dose of human diploid rabies vaccine (HDVC) as soon as possible.
B. Administer one dose of rabies immune globulin (RIG) and HDVC in the buttocks while awaiting the pathology report on the raccoon's brain.
C. Administer RIG immediately in the deltoid and start the HDCV, giving it on days 0, 3, 7, 14, and 28.
D. Contact animal control to capture the raccoon for rabies examination and administer RIG and HDVC to the boy as soon as it is determined that the raccoon has rabies.
E. Infiltrate the wound with RIG and immediately start HDCV vaccine, giving it on days 0, 3, 7, 14, and 28.

BBDDA?
complete guesses ftw.

ADBCA

First 3 were thought about, last 2 guesses FTW!

You seriously think anyone here except you could possibly get the last two?

The first one is Squirrel I think.
I read somewhere it was practically immune to rabies or something.

Okay, here are the answers:

5.E 6.B 7.C 8.E 9.E

Now the explanations:

G_KID got it right, but not for the right reason. Squirrels frequently get the rabies virus, but they commonly die in a few days (and during half of that time they're not able to move at all) so it's hard for them to go around biting other animals. Dogs, on the other hand, can live for more than a month after they're infected. So they're much more likely to pass it on to other animals.

Getting bitten on the face is bad, because rabies becomes fatal when it reaches the brain. The virus actually travels along nerves to reach the brain. It moves about a centimeter a day. So it is effective to cut off your arm if you got bitten on the hand to prevent it from spreading it to the brain.

I don't want to go into the last two questions. They're too technical, obviously.

These are the types of questions we get on our licensing exams, except that there are 800 of these questions on the exam. We take them over two days. It's a grueling process.

Aw, I wanted an electroencephalogram. That's what EEG stands for, right?

That's right.

Even though rabies can cause seizures, by the time the disease progresses to that stage, it's too late to do anything to save the patient.

2/5 =D

2/5 =D

Don't feel bad. Snpbond got 0/5.

A. Administer one dose of human diploid rabies vaccine (HDVC) as soon as possible.

Isn't that dangrous to do so? What it he isn't infected... overduse.
First I think you have to find out if he is ill.

I'm no doctor and I never learnd anything on that subject so I can't gess 8.

Face bite since it's closer to the brain.

The one about The animal that is most likely animal to transmit rabies to humans in African countries such as Ethiopia is quite hard. The Dog is the one I think. It's big so it wont dies quickly and it spends along time along humans. Same thing in the US.

EDIT:

Oh no you already said the right answers... anyway can you tell me if I was right, didn't check your answers.

Why don't you check them?

I got like 2 right, and those were complete guesses. This just isn't common knowledge, man .

Cerebrospinal fluid. Electroencephalogram.

Great words

Yay 3/4, I didn't try one for I never learnd anything about that.

First I think you have to find out if he is ill.

That'll be great and all, but if the animal had escaped and we're not able to capture the animal in time (by the way, how can you even be sure which animal was the one that bit the child?), it's not wise to wait for the test results to come back before doing anything about it.

Besides, it's not dangerous to administer vaccines, even if they're not necessary. Sometimes we just give patients shots all over again because they've lost their immunization record. It's harmless.

Better to be safe

Plx giev mroe Quizzes, Dr. Satch!

Really, you guys really want more of these? I have a lot more, but I wasn't sure whether you guys would be interested.

My wife thought it's a stupid idea to post medical quizzes at TWHL, but I thought rabies is a fascinating topic.

Lol I can see it now, "pediatrician teaches a bunch of geeks to be doctors online"

Who knows, one of you just might turn out to be a doctor in the future. This thread might be a head-start.

I'll post more later. I'm in the process of picking out an interesting topic. I am sure you don't want to take the quiz on newborn exams and muscular dystrophy.

Besides, it's not dangerous to administer vaccines, even if they're not necessary. Sometimes we just give patients shots all over again because they've lost their immunization record. It's harmless.

How should I know it's harmless(there are many dangrous mediciens) I'm no doctor.

But now you know.

Now, for a topic that is near and dear to your heart--menstral cramps!

It may seem useless knowledge now, but you would become the hero when you help your desperate cute girlfriend-to-be with her problems.

11. You are evaluating a 16-year-old patient whose chief complaint is painful periods. She is experiencing increasingly severe pain that begins less than 1 day before menstrual flow and typically is worst on the first 2 days of flow. She reports moderate menstrual bleeding. She denies sexual activity and other medical problems. Bimanual examination reveals no tenderness of the uterus or the posterior cul-de-sac and otherwise is normal. Which of the following is the most likely diagnosis?
A. Endometriosis.
B. Fibroids
C. Imperforate hymen.
D. Ovarian cyst.
E. Primary dysmenorrhea.

12. Which of the following is most likely to be associated with dysmenorrhea?
A. Late onset of menarche.
B. Migraine headaches.
C. Obesity.

I'll give everyone a chance to guess around first, and then I'll post the correct answers later.

posterior cul-de-sac

There is no way that's a biological term :P.

I'm guessing the first one isn't C, and I don't think the second (12) is B. It's definitely not E. 13, no idea. 14, laparoscopy sounds serious-ish, so I'm going to guess C and, er, B &| E.

Alright, seeing you guys aren't expert on menstral cramps, I'll give you the answers early.

11.E 12.D 13.D 14.A

Seventh did fairly well, considering the subject matter.

Just remember, if your girlfriend has menstral cramps, offer her some ibuprofen (Motrin or Advil in the United States). 200 mg standard pill can be purchased over the counter without a prescription. You could be the next hero in her life.

P.S. Don't feel bad for not doing well on the vitamin quiz. I missed two questions myself.

Damn, nothing about scurvy.

1. Tearing? Oh, not "tairing" :D. Oooh. I'm gunna say that or C, 'cos I have no idea what that is and Googling is cheating.

2. E?

3. A! Nah, seriously... C? Maybe one of the sun ones cause breakdowns of vit. D or something? You're the ex-med. student :D.

4. Hell knows. A.

5. One of the first three? You certainly love your h?morrages.

Come on Scrubs, don't fail me now!

1. A or C?
2. A
3. E
4. Aww heck, I dunno... C
5. I'll say...A

If I get any correct, I swear that I did not Google any of them.

Wow, amazing. Ant did better than I did. He only missed one.

I won't post the answers just yet. We'll give the others a chance to guess too.

No other takers?

Holy crap!

Don't post em yet! I just started.

Arg, my computer did something...

anyway my answers are:

1 A
2 E
3 E
4 C
5 A

I swear I didn't look these up.

A fascinating topic indeed! I'd know, firsthand of course!

A 7-year-old girl who takes phenytoin for a seizure disorder is placed on a sulfa drug for a urinary tract infection. She develops ataxia and slurred speech. Of the following, the most likely cause of her symptoms is:
A. Binding of sulfa to phenytoin, impairing absorption from the gastrointestinal tract.
B. Decreased metabolism of phenytoin, increasing its half-life.
C. Increased elimination of phenytoin by induction of cytochrome P450 enzyme.
D. Increased elimination of phenytoin due to alkalinization of the urine by sulfa.
E. Unbinding of phenytoin from plasma proteins, increasing bioavailability.

Bump ftw: I'm gonna say D...Kinda seems right...

Just out of curiosity... what brought all this up in the first place? Some kind of test at your office?

A through D

Shes all fucked up.

Im gonna go with... A...

The correct answer is E. Unbinding of phenytoin from plasma proteins, increasing bioavailability.

All doctors need to do independent study on a regular basis so we keep up with the latest medical advances. I signed up with this program that allows me to read articles and take quizzes to get credits for them.

Hahaha, Luke.

Neat. What the hell is with the Christmas hat, though? Seriously? Knock it off, man. Nothing before December.
