Final answer:
To determine the volume of misoprostol the patient receives per dose, a proportion is set up with the given medication concentration and the prescribed dose, resulting in 1.6 mL per dose after rounding to the nearest tenth.
Step-by-step explanation:
The question revolves around a dosage calculation where a patient is prescribed 115mg of misoprostol, to be taken every 8 hours, and the medication on hand has a concentration of 70mg/1 mL. To find out how many mL of misoprostol the patient will receive per dose, you can set up a simple proportion:
70 mg is to 1 mL as 115 mg is to x mL.
The equation to solve for x is:
70mg/1mL = 115mg/x mL
now, cross-multiply to solve for x:
70mg × x mL = 115mg × 1mL
x = (115mg × 1mL) / 70mg
x = 115/70
x = 1.6428...
After rounding to the nearest tenth, the patient will receive 1.6 mL per dose.
