Calculate the following dosage:
Order: Tegretol 200 mg p.o. t.i.d. Available: 100 mg tablets
How many tablets will you administer?
1 1/2 tablets
2 tablets
4 tablets
3 tablets
The Correct Answer is B
To solve this problem, we need to use the formula:
Desired dose / Available dose = Number of tablets
Plugging in the given values, we get:
200 mg / 100 mg = Number of tablets
2 = Number of tablets
Therefore, the correct dosage is 2 tablets.

Correct Answer is C
Explanation
Step 1: Identify the given information
- Total volume to infuse = 100 mL
- Infusion time = 30 minutes
- Drop factor = 60 gtt/mL
Step 2: Use the formula for flow rate
Flow rate (gtt/min) = (Total Volume (mL) × Drop Factor (gtt/mL)) ÷ Infusion Time (min)
Step 3: Plug in the values
= (100 × 60) ÷ 30
Step 4: Solve step by step
- 100 × 60 = 6000
- 6000 ÷ 30 = 200
Correct Answer is D
Explanation
To calculate the flow rate in drops per minute, we can use the following formula:
Drops per minute = (Flow rate in mL/hour x Drop factor) / 60
Given that we have an order of 1 L of 0.9% NS to infuse at 50 mL/hr and a drop factor of 15 gtt/mL, we can calculate the flow rate as follows:
Drops per minute = (50 x 15) / 60 = **12.5 gtt/min**
Therefore, the correct answer is **d) 15 gtt/min**.
