A nurse is preparing to administer lidocaine via continuous IV infusion at 4 mg/min. Available is lidocaine 2 g dextrose 5% in water 500 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["60"]
Step 1: Determine the Lidocaine Concentration
- The solution contains 2 grams (2000 mg) of lidocaine in 500 mL.
- To find the amount of lidocaine per mL:
2000 mg ÷ 500 mL = 4 mg/mL
Step 2: Calculate the Total Dose per Hour
- The prescribed infusion rate is 4 mg per minute.
- In 1 hour (60 minutes), the total dose is:
4 mg/min × 60 min = 240 mg/hr
Step 3: Determine the Infusion Rate in mL/hr
- Since each mL contains 4 mg of lidocaine:
240 mg ÷ 4 mg/mL = 60 mL/hr
The nurse should set the IV pump to 60 mL/hr for the continuous IV infusion of lidocaine at a rate of 4 mg/min.

Choice C Reason:
Pink, frothy sputum is correct. Normal saline is a common intravenous solution used to treat dehydration. However, in some cases, especially when administered in excessive amounts, it can lead to fluid overload or pulmonary edema. This can manifest as pink, frothy sputum, indicating potential pulmonary congestion or edema, which is a serious adverse effect of fluid overload.
Choice D Reason:
Increased bowel sounds is incorrect. Increased bowel sounds can be seen in various conditions, including gastrointestinal disturbances or hyperactive bowel motility, but it's not typically associated with the adverse effects of normal saline administration.
