Calculo de dosis intravenosas

The primary healthcare provider (PHCP) prescribes 500 mL of 0.45% saline to be administered over one hour. The drop factor is 10 gtts/mL.

How many drops per minute should the nurse set the flow rate at? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

To solve this problem, the nurse will use the formula of total volume x drop factor / time in minutes.

First, take the prescribed volume and multiply it by the drop factor.

500 mL x 10 gtt = 5000 mL

Next, divide the total volume by the minutes.

5000 mL / 60 minutes = 83 gtts/min

Finally, perform appropriate rounding (if needed).

The primary healthcare provider (PHCP) prescribes 500 mL of 0.9% sodium chloride (normal saline) to infuse over four hours via intravenous microdrip tubing.

The nurse sets the flow rate at how many drops per minute? Fill in the Blank. Round your answer to the nearest whole number.

Answer explanation

To solve this problem, the nurse will use the formula of total volume x drop factor / time in minutes.

First, take the prescribed volume and multiply it by the drop factor.

500 mL x 60 gtt (microdrip tubing is always 60) = 30000

Next, calculate the time in minutes by multiplying the hours by 60.

4 hours x 60 = 240 minutes

Finally, divide the volume by the minutes.

30000 mL / 240 minutes = 125 gtt/min

The primary healthcare provider (PHCP) prescribes 100 mL of 0.9% sodium chloride (normal saline) to infuse over two hours via intravenous microdrip tubing.

The nurse sets the flow rate at how many drops per minute? Fill in the Blank. Round your answer to the nearest whole number.

Answer explanation

To solve this problem, the nurse will use the formula of total volume x drop factor / time in minutes.

First, take the prescribed volume and multiply it by the drop factor.

100 mL x 60 gtt (microdrip tubing is always 60 gtts/ml) = 6000

Next, calculate the time in minutes by multiplying the hours by 60.

2 hours x 60 = 120 minutes

Finally, divide the volume by the minutes.

6000 mL / 120 minutes = 50 gtt/min

The primary healthcare provider (PHCP) prescribes 150 mL of sterile water to be administered over one hour. The drop factor is 15 gtts/mL.

How many drops per minute will the nurse set the flow rate at? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

To solve this problem, the nurse will use the formula of total volume x drop factor / time in minutes.

First, take the prescribed volume and multiply it by the drop factor.

150 mL x 15 gtt = 2250 mL

Next, divide the total volume by the minutes.

2250 mL / 60 minutes = 37.5 gtts

Finally, perform appropriate rounding (if needed).

37.5 gtts = 38 gtts/minute

The primary healthcare provider (PHCP) prescribes azithromycin 500 mg daily for a client with sepsis. The medication label reads 500 mg of azithromycin mixed in 250 mL of 0.9% saline. The drop factor is 15 gtts/mL and it is to be infused over 60 minutes.

The nurse sets the flow rate at how many drops per minute? Fill in the blank. Round your answer to the nearest whole number.

Answer explanation

To solve this problem, the nurse will use the formula of total volume x drop factor / time in minutes.

First, take the prescribed volume and multiply it by the drop factor.

250 mL x 15 gtt = 3750

Next, divide the total volume by the minutes.

3750 / 60 minutes = 62.5 gtts

Finally, perform appropriate rounding (if needed).

62.5 gtts = 63 gtts
