Intravenous Therapy Time and IV Push Medications (sherpath)

The healthcare provider dilutes morphine 2 mg so that the concentration is 2 mg/4 mL. The medication is to infuse over 2 minutes. Based on this, the patient will be administered __ mg/mL.

.5 The concentration of the solution is 2 mg/4 mL. Set the formula and solve forX.Xmg/mL =2mg4 mL=0.5mg/mL

Hydromorphone 2 mg per IVP comes in a single-use vial labeled 2 mg/mL. Nine milliliters of medication are added to the active ingredient prior to infusion. The patient will receive __ mg/mL.

0.2 The vial contains 2 mg/mL. Adding 9 mL to the vial results in a concentration of 2 mg/10 mL. Set the formula and solve for X. X mg/mL = 2 mg10 mL = 0.2 mg/mL

A high-potency medication of 50 mg of diphenhydramine via IVP STAT will be diluted to 50 mg/7 mL and infused over 10 minutes. Based on this, the patient will receive __ mL/min.

0.7 1. Set the equation using ratio and proportion and including the known values.7 mL : 10 min= X mL : 1 min2. Multiply the means (middle numbers) and multiply the extremes (outer numbers).10 min × X mL= 7 mL × 1 min3. Solve for X. 10X = 7X = 710= 0.7

There are 50 calibration marks on a 10 mL syringe. A patient is to receive 8 mL over 4 minutes. The nurse will infuse how many calibrations and at what intervals (in seconds)?

1 calibration every 6 seconds 1 calibration every 6 seconds is the correct infusion. The calculation is: Total seconds Total increments => Seconds to deliver each increment24040= 6 seconds (0.5 mL)

An IVP of 8 mL is to be given over 5 minutes at 2 mg/mL. The nurse starts the IVP at 0800 with 8 mL. At 0801, 6.4 mL of the IVP remains and at 0802, 4.8 mL remains. At what time will 3.2 mL of the IVP remain? And, what amount of the IVP will remain at 0804?

1.6 1.6 mL remains at 0804 at a calculated rate of 1.6 mL/min. The calculation is:8 mL : 5 min= X mL : 1 min5 min × X mL= 8 mL × 1 min5X = 8X= 85=1.6 mL/min 0803 The medication is delivered in consecutive minutes, so after the 0802 push, the next medication delivery time is 0803.

The healthcare provider dilutes morphine 2 mg so that the concentration is 2 mg/5 mL. The medication is to infuse over 2 minutes. The medication will be administered at a rate of __ mL/min.

2.5 1. Set the equation using ratio and proportion and including the known information.Total volume : Total minutes= X mL : 1 minute5 mL : 2 min= X mL : 1 minute2. Multiply the means (inner numbers) and multiply the extremes (outer numbers).2 min × X mL= 5 mL × 1 min3. Solve for X.2X = 5X = 52= 2.5

A healthcare provider ordered haloperidol 50 mg diluted in 20 mL NS as an IVP. Based on this, the patient will receive __ mg/mL.

2.5 The concentration of the solution is 50 mg/20 mL. Set the equation and solve it.Xmg/mL =50 mg20 mL =0. 5 mg/mL

A healthcare provider orders 1,200 mL of D5W. It is infusing at 60 gtt/min, and the administration set is a microdrip. Therefore, the infusion time will be __ hour(s). (Use dimensional analysis method.)

20 Use dimensional analysis to set the equation with the known information and then solve for X.X hr= 1 hr60 min× 1 min60 gtt × 60 gtt1 mL × 1,200 mL1=20 hours

A patient is being infused with ½ NS at the infusion rate of 30 gtt/min, using a 15 gtt set over 2 hours. At the end of this period, the patient will receive __ mL of ½ NS. (Use dimensional analysis method.)

240 Use dimensional analysis to set the equation with the known information and then solve for X.X mL= 1 mL15 gtt× 30 gtt1 min × 60 min1 hr × 2 hr1= 3,60015=240 mL

What is the infusion time for 350 mL of D5W, if the drop rate is 15 gtt/min and the drop factor is 10 gtt/mL? (Use dimensional analysis method.)

3 hr 53 min 3 hr 53 min is the correct infusion time. The calculation is:X hr= 1 hr60 min × 1 min15 gtt×10 gtt1 mL× 350 mL=3.88 hr or 3 hr 53 minTo calculate the number of minutes, multiply the number of minutes in an hour (60) by the decimal. In this case, 0.88 × 60 minutes = 52.8 minutes rounded to 53 minutes.

If the drop rate is 80 gtt/min and the drop factor is 10 gtt/mL, what is the infusion time for 1,500 mL of D40W? (Use dimensional analysis method.)

3 hr 8 min 3 hr 8 min is the correct infusion time. The calculation is:X hr= 1 hr60 min× 1 min80 gtt×10 gtt1 mL × 1,500 mL1= 15,0004,800= 3.125 hours or 3 hr 8 min.To calculate the number of minutes, multiply the number of minutes in an hour (60) by the decimal. In this case, 0.125 × 60 minutes = 7.5 minutes or 8 minutes.

500 mL of D5W is to infuse at 100 mL/hr. The infusion will last __ hour(s). (Use dimensional analysis method.)

5 Use dimensional analysis to set the equation with the known information and then solve forX.X hr= 1 hr100 mL× 500 mL1 × 500100=5 hours

A patient is receiving 250 mL of Lactated Ringer (LR) at a rate of 40 mL/hr. How long will this take to infuse? (Use dimensional analysis method.)

6 hr 15 min 6 hr 15 min is the correct infusion time. The calculation is:X hr= 1 hr40 mL× 250 mL1= 25040=6.25 hr or 6 hr 15 min To calculate the number of minutes, multiply the number of minutes in an hour (60) by the decimal. In this case, 0.25 × 60 minutes = 15 minutes.
