Let's break down the problem step by step: **Order:** - Reconstitute 1 gram (1000 mg) of ceftriaxone with **21 mg of lidocaine 1%**. - Each 1 mL of reconstituted solution contains **350 mg of ceftriaxone**. - The provider ordered **750 mg** of ceftriaxone to be administered IM BID. --- ### **Questions:** #### 1. **How many mL of lidocaine will the nurse use to reconstitute the ceftriaxone?** **From the label:** - 1 gram (1000 mg) of ceftriaxone is to be reconstituted with **2.1 mL of lidocaine 1%** to provide 21 mg of lidocaine. **So, the nurse will use**: - **2.1 mL of lidocaine 1%** --- #### 2. **How many mL of reconstituted ceftriaxone will be administered per dose?** - **Each 1 mL contains 350 mg of ceftriaxone** - **Dose ordered: 750 mg** Set up the equation: \[ \text{Volume to administer} = \frac{\text{Dose ordered}}{\text{Concentration per mL}} = \frac{750\ \text{mg}}{350\ \text{mg/mL}} \] \[ \text{Volume to administer} = 2.14\ \text{mL} \] --- ### **Summary of Answers:** 1. **How many mL of lidocaine will the nurse use to reconstitute the ceftriaxone?** - **2.1 mL** 2. **How many mL of reconstituted ceftriaxone will be administered per dose?** - **2.14 mL** (rounded to two decimal places) If you need these answers written in sentence form or filled into the worksheet, let me know!
