Answer:
The correct answer is - 0.25
Explanation:
Calculation of administration right of the dose is very important as higher or low dose can be harmful or lethal as well. If the dose is solution-based then it becomes more complex.
strength of solution: 100mg/0.5ml
So, available dose = 100 mg
Volume would be = 0.5 ml
The dose required 50 mg
Then from "nursing formula":
dose to administration = dose required * volume of solution/dose available
= 50*0.5/100
=0.25ml
