The primary health-care provider prescribes a cough syrup 0.4 g every 4 hours. The dosage strength of the syrup is 100 mg/5 mL. The medication bottle contains a measuring spoon that measures in teaspoons and tablespoons. How many teaspoons will the nurse instruct the client to take?

Answer and Explanation

The Correct Answer is ["4"]

Step 1: Convert the Prescribed Dose to Milligrams

The prescribed dose is 0.4 grams (g), but the medication strength is in milligrams (mg). We need to use the same unit for both.

There are 1000 mg in 1 g.
To convert 0.4 g to mg, we multiply by 1000.
0.4×1000=400
The prescribed dose is 400 mg.

Step 2: Calculate the Volume (in mL) Needed for the Dose

We know that 5 mL of the syrup contains 100 mg of medication. We need to find out how many mL are needed for 400 mg.

To find out how many groups of 100 mg are in 400 mg, we divide:
400÷100=4
This means we need 4 times the volume of syrup that contains 100 mg.
The volume for 100 mg is 5 mL. So, we multiply 4 by 5 mL.
4×5 mL=20 mL
The total volume needed per dose is 20 mL.

Step 3: Convert the Volume to Teaspoons

The measuring spoon is in teaspoons (tsp). We need to convert 20 mL to teaspoons.

There are 5 mL in 1 teaspoon.
To find out how many teaspoons are in 20 mL, we divide 20 by 5.
20÷5=4
The dose is 4 teaspoons.

The nurse will instruct the client to take 4 teaspoons.
