Question

The doctor orders Zofran 8mg PO TID for a patient. The pharmacy has available Zofran in a 100mL bottle labeled 4mg/tsp. How many teaspoons will the nurse administer?

Answer 1

The nurse will need to administer 2 teaspoons of Zofran per dose, as 1 teaspoon contains 4mg and the ordered dose is 8mg. This is determined through setting up and solving a ratio based on the medication's concentration and the prescribed amount.

Step-by-step explanation:

The doctor orders Zofran 8mg PO TID (three times a day) for a patient. The pharmacy has available Zofran in a 100mL bottle labeled 4mg/tsp. To determine how many teaspoons the nurse will administer per dose, you would set up a ratio and proportion based on the given medication strength and the ordered dose.

First, understand that 1 teaspoon (tsp) contains 4mg of Zofran. The doctor's order is for 8mg of Zofran. So, you would use the following calculation:

• 1 tsp = 4mg
• X tsp = 8mg

Cross-multiplying to solve for X, we have:

1 tsp * 8mg = 4mg * X tsp

X = (8mg) / (4mg/tsp)

X = 2 tsp

Therefore, the nurse needs to administer 2 teaspoons of Zofran to the patient for each dose, which is three times a day.
