A practitioner's order prescribes pain medication syrup 100 mg po q4h, but the syrup is available as 150 mg per 1 oz. What will be the amount of medication administered every 4 hours?

Respuesta :

The amount of medication administered every 4 hours is 20 mL

The medical term "po q4h" means per oral(mouth) every 4 hours. From the given information, we need to convert the volume of the drug medication in ounce oz to milliliter mL.

Using the standard conversion rate:

  • 1 oz = 29.57 mL

The mass of the available syrup is 150 mg per 29.57 mL

In a 100 mg, the amount of medication to be administered every 4 hours will be:

[tex]\mathbf{=\dfrac{29.57 \ ml \times 100 \ mg}{150 \ mg}}[/tex]

= 19.71 mL

≅ 20 mL
