Answer 1

1.Given

Order:Nitroglycerin

Dose:gr 1/150SL=0.4mg

Frequency:5 times a day and prn

Available:0.4mg(1/150 gr)

Here 1/150 gr=0.4mg =1 tablet

Therefore for each dose 0.4 mg every 5 minutes upto 5 doses has to be administered

As 1 dose=0.4mg

Then the maximum 5 doses =0.4×5=2mg

A maximum of 2ng can be administered in each dose
