The nurse plans to provide the next shift with the intravenous (IV) fluid balance for a client who had a 440 mL secondary infusion that was started 2 hours ago at a rate of 85 mL/hour via an infusion pump. What is the remaining volume to be infused? (Enter numeric value only.)
The Correct Answer is ["270"]
Calculate the total volume infused so far:
Infusion rate: 85 mL/hour
Time elapsed: 2 hours
Total volume infused:
Volume = Rate x Time
Volume = 85 mL/hour * 2 hours = 170 mL
Calculate the remaining volume to be infused:
Initial volume of secondary infusion: 440 mL
Remaining volume:
Remaining volume = Initial volume - Volume infused
Remaining volume = 440 mL - 170 mL = 270 mL
Therefore, there are 270 mL of fluid remaining to be infused.

Correct Answer is ["17"]
Explanation
Here's how to calculate the drip rate (drops/minute) for the ganciclovir infusion:
1. We know:
Ganciclovir dose: 375 mg (given)
Infusion bag volume: 150 mL (given)
Infusion time: 90 minutes (given) = 1.5 hours (convert minutes to hours)
Drip chamber calibration: 10 drops/mL (given)
2. We need to find:
Drip rate (drops/minute)
3. Steps:
Calculate the concentration of ganciclovir in the bag (assuming all medication is in the bag):
Concentration (mg/mL) = Dose (mg) / Volume (mL)
Concentration (mg/mL) = 375 mg / 150 mL
Concentration (mg/mL) = 2.5 mg/mL
Calculate the total volume to infuse (considering the prescribed dose):
We already know the volume of the bag (150 mL), but this might contain more volume than needed to deliver the prescribed dose.
Calculate the volume to infuse based on the dose and concentration:
Volume to infuse (mL) = Dose (mg) / Concentration (mg/mL)
Volume to infuse (mL) = 375 mg / 2.5 mg/mL
Volume to infuse (mL) = 150 mL (This confirms that the full bag volume delivers the prescribed dose)
Calculate the infusion rate (mL/hour):
Infusion rate (mL/hour) = Total volume to infuse (mL) / Infusion time (hours)
Infusion rate (mL/hour) = 150 mL / 1.5 hours
Infusion rate (mL/hour) = 100 mL/hour
Calculate the drip rate (drops/minute):
Drip rate (drops/minute) = Infusion rate (mL/hour) x Drip chamber calibration (drops/mL)
Drip rate (drops/minute) = 100 mL/hour x 10 drops/mL
Drip rate (drops/minute) = 1000 drops/hour (convert to minutes)
Drip rate (drops/minute) = 1000 drops/hour / 60 minutes/hour
Drip rate (drops/minute) = 16.67 drops/minute (round to nearest whole number as requested)
Therefore, the nurse should regulate the gravity infusion at approximately 17 drops/minute.
Correct Answer is ["0.6"]
Explanation
Here's the corrected calculation for the volume to be administered:
Dosage: 60 mg
Concentration: 100 mg/mL
Volume to administer:
Volume (mL) = Dosage (mg) / Concentration (mg/mL)
Volume (mL) = 60 mg / 100 mg/mL
Volume (mL) = 0.6 mL
Therefore, the nurse should administer 0.6 mL of enoxaparin sodium injection.
