Question

The physician orders 300 mg oral suspension PO q8 hours. Available is 375 mg/5 mL. You should administer _____ mL.

Answer 1

To administer 300 mg of the oral suspension, you should administer 20 mL.

Step-by-step explanation:

To determine the mL of oral suspension to administer, you need to calculate the equivalent mL of the ordered dose. First, determine the concentration of the available suspension, which is 375 mg/5 mL. To find the mL needed for the ordered dose of 300 mg, you can set up a proportion:

375 mg x mL
5 mL 300 mg

Cross-multiply and solve for x:

375 mg * x mL = 5 mL * 300 mg

x mL = (5 mL * 300 mg) / 375 mg

x mL = 20 mL

Therefore, you should administer 20 mL of the oral suspension.
