I never got a 25/25 last year.....sadface

lol

I got 24/25 for hubs, my worst ever for hubs terms tests haha

thats a bit arrogant dont u think?

 

[Cobalt]

No not really, I was just stating a fact. I'm sure there are far more arrogant people out there. Kinda means this terms test was the hardest but whatever : )

 

[skyglow1]

I'm in medicine and you're not. Just stating facts. Doesn't stop me from sounding like an outright prick though does it?

 

[Deleted member 4350]

Haha settle down kids. How did everyone go in HUBS?
What were some questions you guys found tough? I thought 3 GLM questions was a tad unfair. Also, the weighting for short answer qs was rather unbalanced. 3 marks for stating 3 layers of bladder wall and 1 mark for stating "2 structures that allow blood to bypass pulmonary circuit in fetus." Essays were alright aye? GI motility, Filtration barrier/EFP, oogenesis, venous return/veins of leg, thorax ms/joints.

Btw did you guys notice a question in the multichoice that had 2 correct answers? It was a GI question if I remember correctly, but I don't remember the exact details.

60 MCQs is just too much! xD

 

[greenglacier]

That bladder wall question was a bit harsh - 3 marks when it was only briefly covered! Didn't have a problem with the GLM stuff - I mean, they had warned us, and they had also covered fetal circulation in the lab, so you know...

Overall though section 2 was way harder than I had expected. Essays were pretty good though, and the MCQs were pretty manageable.

Meh, I should hopefully be alright for HUBS, and the economics exam (while harder than I had anticipated) on Thursday afternoon went reasonably well, so I am feeling better now about things than I was last week.

 

[SASOL]

This was an answer....

 

[Deleted member 4350]

right subclavian vein for lymph q. For GLM qs - was it umbilical vein and right atrium? The bladder question was fair in my opinion. Her lectures had several words highlighted in red. The bladder wall structures were highlighted. Obviously if there was anything to take from those lectures it would've been those words. But yeah, 3 marks for that question was a bit much (10% of the marks from short answer qs... lol). Bioc, maori and epi in 3 consecutive days. *cuts wrists*

Btw, question about "where are sperm produced", how the hell could that have been 2 marks?! Seriously. What did you guys put for it?

 

[greenglacier]

Fetal circulation answers: ductus arteriosus, foramen ovale, right atrium, umbilical vein.

Oh yes, that stupid sperm one. I put "the seminiferous tubules of the testes". Some people at my hall put down epididymis as well. I suppose that might be the second point they were looking for, but honestly, the question asked "where are sperm produced", and if you're going to go into maturation, you may as well extend your answer to capacitation in the uterus.

What did you put for the "conditions at the external os" question?

 

[Deleted member 4350]

I included epididymis maturation as well. Conditions were thin lining of mucus in canal and cervical strands in the canal which guide the sperm.

I wrote about the thin mucus but for the 2nd condition i said that alkaline solution of the semen should have been present to neutralise the acidic environment of the vagina, providing a safe, non-hostile environment for the sperm. Might be wrong but it was worth a try.

 

[docca.emb]

Yeah I put neutralising the conditions as well but some people from my hall says that the cervix dips down a little or something. I'm so gutted I forgot to go over fetal, 2/3 marks thrown away. I found it was a bit difficult linking the bones and joints in for the respiratory essay. I just named them and sort of stated their general movement.. MCQ was quite good overall i found

 

[Deleted member 4350]

Check L48 for answer to cervix q. There are two points on one of the slides that provide the answer.. I think the resp question just required you to name the joints and possibly state whether they are synovial or cartilagenous in nature. Hows everyone going for BIOC? If you guys are keen for a meet up sometime let me know

 

[Public Liability]

Hey, was that asthma fill in the blank question "spirometer"? sorry if someone mentioned it, too tired to read all the long posts...

HAHA the econ exam was easy thankfully, was just pure repeated questions! What did people find hard about it?

Epi is so crap for me..btw for the terms test 2, the answer to this question is cohort study. Can someone pleeeease explain it (can't they use case control?) :

'Exposure to what type of food was responsible for an outbreak of food poisoning at a​

recent conference in Dunedin?"

 

[Deleted member 4350]

Whaaaa?!! How is that cohort? There is one outcome and many possible exposures, so therefore they must conduct a case-control study. F*** YOU EPI ADMINISTRATORS FOR SCREWING US OVER YET AGAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

P.S. I put spirometer

 

[greenglacier]

Pretty sure the asthma one was "peak expiratory flow rate meter".

Um economics - simple answer is time. If you want to answer the SAQs properly it takes well over an hour, which really rushes you through MCQ...

As for epi, I have heard through the grapevine exactly what happened there. The answer is cohort, and if you look at the lecture slides carefully for the infectious disease outbreak lecture, they answer that exact question with a cohort study. The catch is that it is a retrospective cohort study. Now, official policy of the epi department is that we do not have to know about retrospective cohort studies (when they have tried to teach it to first years, it really hasn't gone well). However, they decided that since investigating the cause of outbreaks is pretty important, they'd teach us it as a special case - where you do a "special type of cohort study". The problem is that John Holmes (lecturer for that lecture) decided (no one seems to know why) that a better term for a retrospective cohort study than "a type of cohort study" is "like a case-control study". During that lecture, the teaching fellows went into a panic when they heard him say that (because the test had already been finalised). Hence, in the review lecture for the second terms test, apparently Patricia Priest was giving quite a few clues that it was cohort, without giving the question away.

So, bottom line, answer is cohort (and after thinking about it, I fully agree with this), but the communication on this matter from the epi department was poor.

Not necessarily. You'd just have more than 2 study groups in your cohort study, and compare each group of people who ate a certain type of food to a comparison group, to obtain a relative risk for each type of food. I did mention about retrospective cohorts to the aquinas people, but I dunno if that helped haha.

I would think a case-control study would do just as well for this type of investigation, but if he said cohort in the lecture then you gotta stick with that. Absolutely retarded to call a retrospective cohort like "a case-control" though. Does nothing but confuse students more. Why couldn't he just said it's like a cohort study but it's done on data in the past?

What was the question about asthma?

Yeah, I think everyone is wondering why he compared it to a case-control. This issue of when you do a case-control and when you do a retrospective cohort by the way is why they don't teach retrospective cohort at first year anymore (otherwise everyone would identify a cohort study as the best study design even when a case-control is most appropriate). The argument from the epi department for retrospective cohort is that the outcome is so common that an odds ratio would be a poor measure of association to use for any purpose outside of finding the cause of the outbreak (e.g. if a catering company wanted to know the safest foods to serve, being able to quote relative risks from retrospective cohort studies is the best way of giving them that data).

Don't remember the exact wording of the asthma question, but it was something like "Mrs. K has asthma, and uses a bronchodilater to control it. This reduces airways resistance by ________________. She monitors her condition using a __________________ meter".

 

[skyglow1]

Oh that's being a bit nit-picky. I would've thought they would just want to know what the cause was. Yeah peak expiratory flow rate meter is what you use to monitor asthma contol.

 

[Deleted member 4350]

I don't recall them mentioning "PEFR meters" in lectures. Slide 30 L 15 states "Spirometry can distinguish between obstructive and restrictive disorders." Spirometer and PEFR meter would both be correct based on the information they've given us imho (although the latter is more accurate).

EDIT: actually now that I think about it, spirometry measures volumes whereas PEFR measures rates. Spirometry can distinguish whether or not a disorder is obstructive or restrictive but PEFR can determine whether it is worsening or not (which was the case for Mrs. K). greenglacier 1215161661 koochkooch 0

 

[skyglow1]

PEFR meters are what people use at home to monitor how their asthma control is going. Spirometry would be waaaaay too impractical to use at home.
