You receive a prescription for pheninazane tablets 50 mg with the following instructions: '2 at 8 am and 10 pm on day 1, 1 at 8 am and 10 pm on day 2, and then 1 at 8 am daily thereafter.' Note: 56 days' supply. Calculate the correct quantity to supply?
Answer (2)
Calculate tablets for day 1: 2
Calculate tablets for day 2: 1
Calculate tablets for remaining 54 days: 54
Calculate total tablets: 2 + 1 + 54 = 57 . The total quantity to supply is 57 .
Explanation
Understanding the Problem We need to calculate the total number of pheninazane tablets required for a 56-day supply based on the given prescription instructions. The prescription specifies a dosage of 2 tablets on day 1, 1 tablet on day 2, and 1 tablet daily for the remaining days.
Tablets on Day 1 First, we account for the tablets taken on day 1. According to the prescription, 2 tablets are taken on day 1.
Tablets on Day 2 Next, we account for the tablets taken on day 2. The prescription indicates that 1 tablet is taken on day 2.
Remaining Days Now, we calculate the number of days remaining after the first two days. Since the total duration is 56 days, the remaining days are calculated as: 56 − 2 = 54 So, there are 54 days remaining.
Tablets for Remaining Days For each of the remaining 54 days, 1 tablet is taken daily. Therefore, the total number of tablets taken during these 54 days is: 54 × 1 = 54 So, 54 tablets are needed for the remaining days.
Total Tablets Required Finally, we sum the number of tablets taken on day 1, day 2, and the remaining 54 days to find the total number of tablets required: 2 + 1 + 54 = 57 Therefore, the total number of tablets needed for the 56-day supply is 57.
Final Answer Therefore, the total quantity to supply is 57 tablets.
Examples
Imagine you are managing the inventory of a pharmacy. A doctor prescribes a specific medication dosage for a patient over a period of time. Accurately calculating the total number of tablets needed ensures that the patient receives the correct amount of medication for the entire treatment duration, preventing shortages or oversupply. This calculation is crucial for effective inventory management and patient care, ensuring that the pharmacy can meet the needs of its patients without waste.
The total quantity of pheninazane tablets needed based on the prescription is 57. This includes 2 tablets for day 1, 1 tablet for day 2, and 54 tablets for the remaining days (1 tablet each for 54 days). Therefore, the pharmacist should supply a total of 57 tablets to fulfill the 56-day supply requirement.
