Question

A nurse is caring for a client who has a prescription for ranitidine 150 mg PO BID. Available is ranitidine syrup 15 mg/mL. How many mL should the nurse administer each day? a) 5 mL b) 10 mL c) 15 mL d) 20 mL

Answer 1

To convert the prescription of 150 mg of ranitidine taken orally twice daily to milliliters, we calculate the total daily dosage in mg and divide by the concentration of the available medication in mg/mL. This gives a total of 20 mL of ranitidine syrup per day.

Step-by-step explanation:

The question is asking how many milliliters of ranitidine syrup the nurse should administer each day if the patient's prescription is ranitidine 150 mg taken orally twice daily (PO BID) and the available ranitidine concentration is 15 mg/mL.

To solve this, we need to convert the prescription dose in mg to mL using the known concentration of the syrup. Firstly, the total daily dosage is 150 mg BID, so that's 150 mg * 2 = 300 mg in total per day.

So, to find out the volume in mL, we divide the total daily dosage (in mg) by the concentration of the available medication (in mg/mL): 300 mg ÷ 15 mg/mL = 20 mL. Therefore, the nurse should administer 20 mL of ranitidine syrup per day.
