A provider order is written for prochlorperazine (Compazine®) 7.5 mg IV q 4 hrs prn N/V. Prochlorperazine (Compazine®) is available in a prefilled syringe labeled 10 mg/2 mL. How many milliliters should be given?

Since the pre-filled syringe carries a label that specifies 10 mg / 2 ml, it can be deduced that the syringe contains 10 mg of the medicine in the 2 mL that is evident in the syringe, therefore, with these data and taking into account that the recommended dose in the order is 7.5 mg, a simple rule of three can be performed with the data obtained:

10 mg = 2 mL
7.5 mg = X

Then we proceed to calculate X:

X = (7.5 * 2) / 10
X = 15/10
X = 1.5 mL

1.5 milliliters is the dose that must be supplied every four hours following the indications in the order.

Answer:

1.5 ml

Explanation:

Given that;

A provider order is written for prochlorperazine (Compazine®) 7.5 mg

That represents the desired dose (D)= 7.5 mg

Prochlorperazine (Compazine®) is available in a prefilled syringe labeled 10 mg/2 mL

The dose at hand = 10 mg

The quantity in milliliters = 2mL

To calculate the amount of milliliters that is required to be given; we use the following expression = [tex]\frac{desried dose}{dose in hand}*quantity in milliliters[/tex]

= [tex]\frac{7.5}{10}*2[/tex]

= 0.75 × 2

= 1.5 ml

The amount of milliliters that is required to be given = 1.5 ml
