Thank a lot all!!
I was wondering if you weren't too busy that you could help me with another stat question. Keep getting these all wrong.
Can't seem to figure this one out.
A screening program is initiated for detection of vaginal C. trachomatis infection among first year college women students. At the initial screening Chlamydiae is found in 500 of the 2500 students. One year later, the screening shows that the infection has affected an additional 200 students. Which of the following is the annual incidence of C. trachomatis infection in this population of women students.
A.) 8%
B) 10
C) 16
D) 20
E) 28
Incidence is all new cases over the total population. So I did 200 over 2500 and got 8% but it was wrong,
whats the answer of that question asking about tanner stage at 9 years..is it normal?
if they were closed, that would be a valsalva maneuver. you can ONLY move air thru the vocal cords and make any sort of sound when the cords are open.are you sure while coughing vocal cords are open?
Are u sure You marked it B ?i have very bad concept of control group..as i marked B got it wrong..i though non diseased with no riskfactor
for 2 i would put C because you are evaluating a risk factor.
I agree on that, I see why B is a better choice.yea as worded, that makes sense. However, the experimental design is probably this:
Take kids w/ parents at the foundry and evaluate them all for motor impairments.
Takes kids w/ parents not at the foundry, evaluate them for motor impairments.
Compare the two groups. So in that sense, B is the better answer because it properly sets up a comparison.
I think that question is just poorly worded and doesn't really test your ability to design an experiment.
also need answer of this
this one with explaination .
plz explain
can you explain that one, they looked normal to me lol then again Iam bad with that stuffits E..there is accumulation of Interstital cells
Hey, if anyone can explain the following biochem question I'd greatly appreciate it! thanks in advance.
Its largeOk i'm so sorry! Just one last question. Sorry for posting so much it's just my test is next week!!!

stole my thunder bra! lolDude has sciatica, evidenced by the radiation down the leg. Therefore, C.
CK+, ANA+ sounds like Dermatomyositis, especially given the upper extermity proximal muscle weakness. I've never seen it present that early in any material though.
yea, it's Pcomm. 2nd most common place for berry aneurysms and it also presents with CN III palsy.
yep, physostigimine is the preferred anti-muscarinic because it penetrates CNS.
sounds like a testicular torsion, esp with radiating pain to the groin.
only ventricular cardiac cells are permanent cells in the above list.
stole my thunder bra! lol
if you have a renal calculus near the bladder it can radiate to the groin as well, thats why I picked renal calc
Thanks Fatalis! Do you happen to have any idea about the micro pharm question?
Yeah, Ampho B is the correct answer. Had this one right. Although, don't you think it's blasto? Pairs of cell with broad base budding.looks like cryptococus, so ampho B
infiltrate/consolidation rules out viral infections.
My issue with this question, yes incidence is new cases/total pop at risk, but getting chlamydia one year does not make you any less at risk for getting it the next year...Also, when they say "an additional 200 test positive " the next year, I interpret that as, the next year there are 700 who test positive, so 700/2500 = 28%.Remember that incidence is the number of new cases over the population AT RISK. So in this case, the question told us that 500 of the 2500 tested positive for the disease. This leaves 2000 at risk for the next year. Thus, 200/2000= 10%. B
Yeah, Ampho B is the correct answer. Had this one right. Although, don't you think it's blasto? Pairs of cell with broad base budding.
Sorry for not having the question and answers in front of me as I was pressed for time and didn't screen cap it.
1. Pt. went to Kenya, watery + bloody diarrhea, 12 micrometer trophozoites with erythrophagocytosis. What organism? None of the malarias was an answer choice.
2. Sigmoid colon adenocarcinoma, spreads via which set of lymph nodes?
So, if we're excluding reinfection, would it be 200 new cases divided by 1800 people at risk??
This statement helped a lot, so does this mean that the answer for 50 (just posted) should be "c"?Because with a case control you already have your outcome and you're looking at exposure.
I put down B & E and got it right.
