Final answer:
To calculate the number of tablets that should be given for each dose, divide the number of units per dose by the number of units in one tablet. In this case, each dose should be given 1 tablet.
Step-by-step explanation:
To calculate the number of tablets that should be given for each dose, we need to determine the total number of tablets required for the order and divide it by the number of doses.
The order is for 50,000 units of penicillin G potassium per kg of body mass per day, and the tablets available are 500,000 unit tablets.
Since there are 7 equally divided doses, we divide 50,000 units by 7 to get the number of units per dose. Now, divide the number of units per dose by the number of units in one tablet (500,000 units) to find the number of tablets that should be given:
50,000 units ÷ 7) ÷ (500,000 units) = Number of tablets per dose
By simplifying the above equation, we get:
1 ÷ 7 = Number of tablets per dose
Therefore, each dose should be given 1 tablet. So, the correct answer is c) 1 tablet.
