Question

A 62 year old female patient, who weighs 132 pounds, is scheduled to receive Avastin Question 20 therapy for treatment of colorectal cancer. The physician has ordered a dose of 14mg/kg of Avastin to be diluted with 1100ml of normal saline and given IVPB over 60 minutes. Based on this label, what will be the total volume (mL) in the IVPB bag prior to administration? (round to one decimal place)

Answer 1

The total volume in the IVPB bag prior to administration is 1940 ml.

Step-by-step explanation:

The question involves calculating the total volume of an IVPB (intravenous piggyback) bag containing Avastin, a medication used in the treatment of colorectal cancer, based on a specific dose ordered by a physician.

To determine the total volume of Avastin to be added to the IVPB bag, we first need to convert the patient's weight from pounds to kilograms, calculate the total milligrams of Avastin needed, and then use the dilution method to prepare the IVPB.

1. Weight Conversion:

132 pounds : 2.2 = 60 kg.

2. Total Avastin Dose:

60 kg x 14 mg/kg = 840 mg.

3. IVPB Preparation:

The total volume to be prepared is the sum of the Avastin dose (840 mg) and the normal saline volume (1100 mL).

So, the total volume in the IVPB bag prior to administration is

840 mg + 1100 ml = 1940 ml.

The final answer is 1940 mL.
