hi i have a test on monday and im stuck on these type of questions can u please help me... i need to see how to work it out so i can work others the same out ...?? pls
the question is mr. simons, an insulin dependant diabetic requires sliding scale insulin post-operatively. calculate the amount to be drawn up for each
b.s.l range. stock strengh is 100 units per ml
i) bsl below 6.2mmol/l = 0 insulin
ii) bsl 6.3 - 10mmol/l give 12 units=__________ml
iii) bsl 12.1 - 15mmol/l give 18 units= ________ml
iv) bsl 18.1mmol/l and over give 25 units= ____ml
pls help i have no idea
what is mmol as well??
for i) tried and got
no. of units req = 6.2mmol
no. of units stock srength= 100units/ml
volume in stock strength = 1ml
= 0.062ml ?? its wrong isnt it??
thanks for anyone who can help

Think about this for a minute.
An easy formula to use is:
what you want x volume
what you've got
So for no. 1:
0 units x 1ml = 0mL
12 units x 1mL = 12/100 = 0.12mL
You try and work out the rest...
The mmols are a range that help guide you as to the amount of insulin you are to give. Say your patient's BSL was 7.2mmol. That comes between the BSL range of 6.3 and 10 mmol. The guideline is that if it is between that range that you would give 12 units. (ii). And you have calculated that 12 units = 0.12 mL. So you give 0.12mL
By calculating i, ii, iii, iv, and v you will get a volume for each of these ranges. So that is why it is important to calculate these first, so that when it comes to administration based on someones BSL you will know how much to give.
