Question

Transcribed Image Text:On this educational page, we’re going to solve a practical problem involving medication dosage reconstitution.
### Problem Statement
Doris has reconstituted a bottle of Cefprozil® Oral Suspension to fill a patient’s prescription. The prescription calls for 400 mg of Cefprozil® every 12 hours (q12h) for 7 days. Doris needs to know if the amount of reconstituted medication in the bottle will be enough to last the patient for 7 days. Calculate the total amount of medication in the bottle after this medication has been reconstituted.
### Medication Information
The label on the medication bottle provides the following details:
**CEFPROZIL for Oral Suspension USP**
- **Concentration**: 125 mg per 5 mL
- **Total volume when mixed**: 75 mL
### Calculation Steps
1. **Determine the daily dosage required:**
- Prescription: 400 mg every 12 hours
- Daily total dosage = 400 mg (morning) + 400 mg (evening) = 800 mg per day
2. **Calculate the total dosage required for 7 days:**
- Total amount needed = 800 mg/day × 7 days = 5600 mg
3. **Convert the required dosage to milliliters (mL):**
- The reconstitution concentration is 125 mg in each 5 mL
- Convert to mg per mL: \( \frac{125 \text{ mg}}{5 \text{ mL}} = 25 \text{ mg/mL} \)
- Total mL needed: \( \frac{5600 \text{ mg}}{25 \text{ mg/mL}} = 224 \text{ mL} \)
4. **Compare the required mL to the available mL in the bottle:**
- The reconstituted bottle contains 75 mL of suspension.
### Conclusion
The reconstituted bottle contains 75 mL, while the required dosage over 7 days is 224 mL. Therefore, 75 mL is not enough to last 7 days.
**Graph/Diagram Explanation:**
In the image, there is no graph or diagram, but the label contains critical information which includes:
1. The NDC number for the medication.
2. The active component and the concentration.
3. Storage information stating it should be stored at
