In Kyra's case, how many DES tablets are needed for the first three days?

• A. 5
• B. 3
• C. 2
• D. 4

Answer: (B)

The key idea is to add up the daily doses over the specified time period. If the plan calls for giving one DES tablet each day for the first three days, you simply add them: 1 + 1 + 1 equals 3. So three tablets are needed in total for the first three days. This matches the dosing instruction for that initial period. If any day required a different amount (for example a half tablet or a higher dose), you would convert that to the appropriate fraction and sum all daily amounts for those days.
