Answer:
To calculate how many mL of the 5% aminophylline solution should be given, we need to use the formula:
(amount of medication needed / concentration of medication available) x volume of medication available = volume of medication to be administered
Using this formula, we can calculate the volume of the aminophylline solution to be given as follows:
(amount of medication needed) = 50 mg (concentration of medication available) = 5% (volume of medication available) = 50 mL
First, we need to convert 50 mg to grams by dividing by 1000:
50 mg / 1000 = 0.05 g
Next, we need to calculate the amount of aminophylline solution required. We can do this by rearranging the formula as follows:
(volume of medication to be administered) = (amount of medication needed / concentration of medication available) x volume of medication available
(volume of medication to be administered) = (0.05 g / 0.05 g/mL) x 1 mL
(volume of medication to be administered) = 1 mL
Therefore, to administer 50 mg of aminophylline orally every 8 hours, 1 mL of the 5% aminophylline solution should be given.
