Question

A male client receives a prescription for ondansetron hydrochloride (Zofran) 4 mg IV to prevent postoperative nausea after an inguinal hernia repair. The medication is available in 2 mg/ml. How many ml should the nurse administer? (Enter numeric value only.)Use ratio and proportion, 4 mg : X ml = 2 mg : 1 ml 2X = 4 X = 2

Answer 1

A male client prescribed 4 mg IV of ondansetron (Zofran) will require 2 ml of the medication at a concentration of 2 mg/ml, as determined by using ratio and proportion.

Step-by-step explanation:

The student's question relates to the administration of a medication, specifically ondansetron hydrochloride (Zofran), which is used to prevent postoperative nausea. The question involves calculating the correct dosage of the medication to be administered intravenously. Using a simple ratio and proportion method based on the concentration of the available medication, we can determine the correct volume to administer.

Given the prescription for 4 mg IV of Zofran and the medication's available concentration at 2 mg/ml, we can set up the following equation to solve for the volume (X ml):

4 mg : X ml = 2 mg : 1 ml

Multiplying both sides of the proportion to solve for X gives us:

2*X = 4

X = 4 / 2

X = 2

Therefore, the nurse should administer 2 ml of Zofran to the patient.
