HESI Dosage Calculations - Exam Topics Sample Questions

You have an order for a medication to be taken 2 mg twice a day for 14 days. You have 1 mg tablets on hand. How many of these tablets do you need?

Correct Answer:
56
to solve how many 1 mg tablets are needed when the prescribed medication is 2 mg taken twice a day for 14 days, we start by calculating the total daily dosage in milligrams.

the prescription specifies 2 mg of medication to be taken twice a day. therefore, daily, the total dosage is: \[ 2 \, \text{mg} \times 2 = 4 \, \text{mg} \]

next, since you have 1 mg tablets available, you need to determine how many 1 mg tablets are required to meet the 4 mg daily dosage: \[ 4 \, \text{mg} \div 1 \, \text{mg/tablet} = 4 \, \text{tablets} \]

these 4 tablets are needed each day. the prescription lasts for 14 days, so the total number of tablets needed over the 14-day period is: \[ 4 \, \text{tablets/day} \times 14 \, \text{days} = 56 \, \text{tablets} \]

therefore, you will need to procure a total of 56 tablets of the 1 mg medication to adhere to the prescribed 14-day regimen of 2 mg taken twice daily. this computation ensures you have enough medication for the prescribed duration without any shortage.
