Answer :
Final answer:
In order to administer 30mg of a drug that is available as 5mg/teaspoon, you would need to give 2 tablespoons, because every tablespoon contains 15mg of the drug and 30mg divided by 15mg equals 2.
Explanation:
To find out how many tablespoons of the drug are needed, you need to work out a simple mathematical calculation. The ratio is 5mg per teaspoon. Since a tablespoon is equal to 3 teaspoons, that means there's 15mg of the drug per tablespoon. Given that the patient needs to receive 30mg of the drug, you'd divide the needed dosage (30mg) by the dosage per tablespoon (15mg). So, 30mg / 15mg = 2 tablespoons. Therefore, the correct answer is B.2 Tablespoons. To determine how many tablespoons to give the patient, we need to calculate the number of 5mg/teaspoon doses needed to reach the prescribed dosage of 30mg.
Since each teaspoon contains 5mg, we divide 30mg by 5mg to find that 6 teaspoons are needed. Since there are 3 teaspoons in a tablespoon, we divide 6 teaspoons by 3 to find that 2 tablespoons are needed. Therefore, the correct answer is B. 2 tablespoons.
