Question
The doctor has prescribed penicillin to combat a flu you are experiencing. She said you need 0.5 g three times a day for 5 days. The pharmacist gives you pills that have a strength of 250mg per pill. How many pills will you have to take at one time?
Solution
-
Primero, necesitamos convertir la dosis de penicilina prescrita de gramos a miligramos, ya que la fuerza de las pastillas está en miligramos. Sabemos que 1 gramo es igual a 1000 miligramos, por lo tanto, 0.5 gramos es igual a 500 miligramos.
-
Luego, debemos dividir la dosis prescrita en miligramos (500 mg) por la fuerza de cada pastilla (250 mg). Esto nos dará el número de pastillas que necesitamos tomar cada vez.
500 mg / 250 mg = 2 pastillas
Por lo tanto, tendrás que tomar 2 pastillas cada vez.
