A client is receiving one liter of DW 0.45% normal saline IV every 8 hours by gravity infusion. The IV tubing has a drip factor of 12 gtt/mL. The nurse should regulate the IV to deliver how many drops per minute?
(Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["25"]
To answer this question, we need to find the flow rate of the IV in milliliters per hour, and then multiply it by the drip factor of the IV tubing to get the drops per minute. The flow rate of the IV is the volume of fluid divided by the time of infusion, which is one
liter (or 1000 ml) divided by eight hours, or 125 ml/hour. The drip factor of the IV tubing is 12 gtt/mL, so the drops per minute are 125 x 12 / 60 = 25 gtt/minute. Therefore, the nurse should regulate the IV to deliver 25 drops per minute.

Correct Answer is ["83"]
Explanation
To answer this question, we need to calculate the infusion rate in gtt/min using the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
We are given the volume of the infusion as 1 liter and the drop factor as 60 gtt/mL. We need to convert the volume from liters to milliliters by multiplying by 1000 and convert the time from hours to minutes by multiplying by 60. Therefore, we get:
Volume (mL) = 1 L x 1000 mL/L
Volume (mL) = 1000 mL
Time (min) = 12 hours x 60 min/hour
Time (min) = 720 min
Now we can plug in the values into the formula and get:
Infusion rate (gtt/min) = 1000 mL x 60 gtt/mL / 720 min
Infusion rate (gtt/min) = 60000 gtt / 720 min
Infusion rate (gtt/min) = 83.3333 gtt/min
The nurse should regulate the infusion at 83 gtt/min. This is the numerical value and it is rounded to the nearest whole number, as instructed.
Correct Answer is ["0.8"]
Explanation
To answer this question, we need to use the formula:
Volume (mL) = Dose (mg) x Concentration (mL/mg)
Plugging in the values given, we get:
Volume (mL) = 20 mg x (5 mL / 125 mg)
Simplifying, we get:
Volume (mL) = 0.8 mL
Therefore, the nurse should administer 0.8 mL of phenytoin suspension to the child every 8 hours.
