Detailed explaination for number 2since the maximum dose allowed is 4.4mg/kg of lidocain 1:80 0001.

7 x 125= 875 mg ( but remember you must never exceed the maximum dose that is 500 mg, no matter what the weight of the patient) so you will use 500 mg in the second equationif the patient weight was 70 then its 7mg x 70kg = 490 mg since its below 500 maximum dose you will us it in the second equation.In a 20% lidocain means there is 1ml= 20 mg that`s because:20% lidocain means 2gm per 100 ml of solution that`s equal

to 2000 mg per 100 ml ( remove the zeros) 20 mg per 1 ml2. then do a cross multiplication if:1ml= 20mg thenx ml = 500 mgthat equals to= 25 from the available options 24 is the closest you can`t give 26 ml or u will be exceeding the maximum dose.so there are some points u need to memorize2% plain lidocaine maximum dose is 4.4mg/kg maximum is 300 mg2% lidocaine with 1:80 000

 Odell states - - fixed dose recommendations are based on safety limit for the elusive fit 70 kg man, which is 4.4/kg  (300 mg)  (70 x 4.4 = 308 mg )- maximum recommended dose is irrespective of presence of vasoconstrictor . it is 4.4mg/kg (300mg) in all cases with with or with out epinephrine. 

- It is no longer considered that larger doses be given in one treatment session if preparation contains vasoconstrictor   ques #2 :-20 mg of the drug is present in 1 ml of la                    ( max mg that can be given is 300mg .it does not matter how obese  300 mg of the drug is present in ?ml of la                         the person is or whether the la is with or without vasoconstrictor)

     ?ml=300/20           =15 ml (equivalent to 7 cartridges) closest option is 16 mlques#1:- 20mg of the drug in1 ml of la                                       (max mg that can be given to a 20 kg person is 20x4.4=88mg) 

 88mg of drug in ?ml of la?ml=88/20     = 4.4ml -This is what i have got from Odell . I have read scully too . but is'nt odell about  clinical  problems solving in dentistry 

BOTH ARE GREAT BOOKS  BUT THEY HAVE  A BIT OF DIFFERENCE ON THIS SUBJECT PLEASE CORRECT  AND ADVICE

?ml=300/20 =15 ml (equivalent to 7 cartridges) closest option is 16 mlques#1:- 20mg of the drug in1 ml of la (max mg that can be given to a 20 kg person is 20x4.4=88mg)

88mg of drug in ?ml of la?ml=88/20 = 4.4ml -This is what i have got from Odell . I have read scully too . but is'nt odell about clinical problems solving in dentistry

So you want to say we should not consider value with vasoconstrictor which is 7mg/kg with maximum of 500 mg.I havent read odell ever but this is what we study at our undergraduate level but may be what you are saying is correct as you read it and even pink book has not described about 7 mg/kg.so i think we should follow 4.4mg/kg.What do you think guys?Sent from Samsung Mobile

For 2% Lignocaine

Its 4.4 /kg weight.

So for 20 kg 4.4*20 = 88 mg

One 2.2 ml cartr contain 44 mg

So here . It will be 88/44 = 2 cartrg.
