A nurse preparing to administer dextrose 5% in lactated Ringer's 2 L IV to infuse over 12 hr. The drop factor on the manual IV tubing is 20 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["56"]

Determine the flow rate in mL/hr:

The client is to receive 2 L of dextrose 5% in lactated Ringer's IV.

There are 1000 mL in 1 L, so 2 L = 2 x 1000 mL.

The medication is to be administered over 12 hours.

To find the flow rate in mL/hr, we can divide the total volume by the time:

Flow rate (mL/hr) = Total volume (mL) / Time (hr)

Flow rate = 2000 mL / 12 hr

Calculating the flow rate:

Flow rate = 166.67 mL/hr

Calculate the flow rate in mL/min:

There are 60 minutes in an hour.

Flow rate in mL/min: 166.67 mL/hr ÷ 60 min/hr = 2.7778 mL/min.

Calculate the drip rate in gtt/min:

The drip factor of the tubing is 20 gtt/mL.

This means that for every 1 mL, there are 20 drops.

To find the drip rate in gtt/min:

Drip rate (gtt/min) = Flow rate (mL/min) × Drip factor (gtt/mL)

Drip rate = 2.7778 mL/min × 20 gtt/mL

Calculating the drip rate:

Drip rate = 55.56 gtt/min

Round the answer to the nearest whole number:

Rounding 55.56 to the nearest whole number gives us 56 gtt/min.

Correct Answer is ["0.2"]

Explanation

Determine the total daily dosage:

The client is prescribed 7.5 mg of methotrexate.

Calculate the dosage per dose:

The medication is to be administered in a single dose.

Dosage per dose is 7.5 mg.

Determine the volume per dose:

The methotrexate injection contains 15 mg per 0.4 mL.

The nurse needs to administer 7.5 mg per dose.

To find the volume per dose, we can set up a proportion:

15 mg / 0.4 mL = 7.5 mg / x mL

Cross-multiplying gives us:

15x = 3

Dividing both sides by 15, we get:

x = 0.2 mL
