1. whistle in inhaling device .
does that mean the inhaler in working well.??, not working well. ?? capsule stucked on the spacer? not inhaled properly ??

I am studing from Aphap and have rade about FEV and peak flow meter and red , yellow , green zone. these zone are in 80-100% , 50-79% , <50 %

2.In pre Naplex ,there was a question with PFM and values in L/hour ???? how these values are calculated??

3.cal carbonate 500mg 2 tab tid . what is the elemental cal pt is getting in a day?? no at. wt or mol wt is given . so does that mean we need to know all these values??if not how to get the answer?

PFM is calculated in reference to the normal peak flow meter. in question, they might have given the regular PFM let's say like 200 L/hr, red zone will be less than 30% so find out the percentage accordingly (200*30/100 = 60 L/hr).

You just need to remember the elemental Ca in CaCO3 and CaCitrate which are the only famous Ca suppliment.

Sulfacetamide may produce burning sensation. Check the rxlist.com for further counselling.

I believe red zone less than 50% . yellow is 50-79 % and green is >80%
so if they give 200 then 50/100*200 =100L/hour . so that mean this100l/h is red zone?? correct me if I am wrong.

Red zone: <50%
Yellow zone: 50-79%
Green zone: 80% and up
Remember that the 100% represent the BEST PEF, not the normal.
When you go to the doc you are asked to do the test multiple times and pick the highest value you get among the attempts, not an average or a intermediate value.
Now, after a while, your asthma symptoms may regress and can achieve a PEF that is actually 115% of the last best value, in this case I assume the 115% will replace the old best value from that point on and will become the 100%.
I honestly didnot study what the average pef is but I doubt it's 200
I think it's between 4-6 liters, I don't think an elephant has lungs capable of containing 200L of air. 200ml seems more the pef of a cat, but I may be wrong. I am surprised they asked how the PEF, RV, FEV are calculated, I really do not know that. I also cheched the APHA, prontopass and CPR, they don't say. And the whistle is to make sure you donot inhale too fast, if you do it whistles and you know you are inhaling too fast.
As for the Ca question, I recall from studying the prontopass that Ca Carbonate has 40% of elemental Ca, 21% for Ca Citrate and 25% for Ca Acetate. Having this info would be enough to answer this question, but if they ask about Mg or Al salts I would be lost too, not going to study the elements' table.
Sulfacetamide is famous for stinging in the eye and even though it's a solution, it needs shacking, remember that it sounds like a carbonic anidrase inhibitor but it's instead an antibiotic. Other stuff, don't touch the dropper with dirty hands, remove contact lenses, avoid other eye drops at the same time, and apply drops to the corner of the eye (near nose) while looking upward.
Man.. that's a nasty exam!

Hi,

If you refer rxlist.com for sulfacetamide eye drops, it doesn't seem like it needs shaking before administration. Correct me, if I am wrong.
These things are too much to remember.

Thanks,

Thanks,

I read that on drugs.com I think, it was a while ago.
I would not worry about it anyway because if it's in the prenaplex I doubt it will appear in the naplex again any time soon
