@@PharmaceuticalCalculationsEasy I need help sir Question: A physician orders diphenhydramine (Benadryl) 50 mg IM q4 h. The available stock is 25 mg/2 mL. Calculate the amount to dispense?
Q3 for the ear drops can be also solved by C1V1=CfVf C1V1= 75%xV1 CfVf=50%x60ml V1=50x60/75=40mL alcohol, Then 60mL(total volume)_40mL(alc)=20mL water 🌊
You are absolutely correct TK. You can solve question 4 using the approach you shared in the comment. Thank you for watching and for actively supporting the channel.
why is it that in certain question we convert using specific gravity in the beginning (phosphoric acid question) and in others we convert right in the end (eg in the 400ml conc HCL question) because if we solve it in the beginning and end gives us two different answers!
