Final answer:
To find the number of teaspoons of Augmetin 250 mg oral suspension to administer, calculate the volume (12.5 mL) that contains the prescribed dose and then convert that volume to teaspoons (2.5 teaspoons).
Step-by-step explanation:
To solve how many teaspoons the nurse should administer for each dose of Augmetin 250 mg oral suspension, we must first calculate the volume of suspension that contains 250 mg of the medication. Since the concentration of the suspension is 100 mg in 5 mL, we set up a proportion to solve for the required volume (in mL) for the 250 mg dose:
100 mg / 5 mL = 250 mg / x
Multiplying both sides by x and then dividing both sides by 100 mg yields:
x = (250 mg * 5 mL) / 100 mg
x = 12.5 mL
Since 1 teaspoon is approximately equivalent to 5 mL, the nurse needs to administer:
12.5 mL / 5 mL per teaspoon = 2.5 teaspoons
Therefore, 2.5 teaspoons of the oral suspension should be given every 12 hours.
