Acid-base imbalance - questions

These are (unedited) questions from Lim Wei Li, a medical student in Year 2. I have e-mailed the questions to my colleagues and to Physiology Dept. I hope to put up some responses/answers soon. Please check back later.

dr.i have some things that i dun understand..

Q1 alkalosis causes decrese in free ca ions due to association with protein. but in milk alkali syndrome. the alkaemia will cause the increase in renal absorbtion of ca> hypercalcemia...so..

A) is it alkalosis will cause decrease in ca..provided only if the kidney is dysfunctional? so there is no reabsorption?

b) does alkaemia and alkalosis have different effects on the ca ions? if yes, how? examples?

Q2 the non-anion gap metabolic acidosis in case of renal tubular acidosis type 1,2,4...frm what i understand is during...there is when alkali decrese..>bicarbonate loss. chloride replaces it via reabsorption> so the measued anion gap is the same..does this mean these renal tubular acidosis are all hyperchloreamic acidosis?

Q3) from what i understand last year.. acidosis will cause hyperkalaemia.due exchange of acid wif potassium ions...but why renal tubular acidosis type 1 and 4 is related to hypokalaemia?

Q4)dr...from the primer in chemical pathology...pg51 (normal anion gap acidosis is devided to hyper and hypokalaemic)...does this mean that the potassium disruptions only occur when there is normal anion gap...and why so? i dun quite understand the explainations i got from the book...

i hope you can help me clear up some of these doubts and queries..thanking you in advance..

Acid-Base Imbalance

My lecture to Year 2 MD is tomorrow at 11.30am-12.30pm in DK3. I have prepared my PPT but I may need to re-do some of the slides tonight.

Last year I submitted an exam question on acid-base imbalance and that went into Professional 2/2011 exam (that was what the Block Coordinator informed me).

I again submitted the same question last week for this academic year 2011/2012, but I was told by the Block Coordinator to change it a bit as it maybe taken for either Selanjar 1 or Professional 2 exam. Because of this I have to re-engineer some of the slides so the emphasis is now on skills and data interpretation rather than a mere theoretical lecture.

It is not easy to engineer exam quesitons and teach the right skills in a 1-hour lecture. Some students get lost in my lecture. Some students go blank after my lecture. Some students can't make out head or tail from my lecture notes (printed notes).

How skillful students become actually depends on how frequent they try out their skills at data interpretation. And interpreting blood gas results is a desirous skill. I will teach you a bit but you will need to practise. You can Google acid-base questions and try them yourself.
