the client has been prescribed a 4 gram bolus of magnesium sulfate to run over 20 minutes. it arrives from the pharmacy diluted in 250 ml of normal saline. what rate does the nurse set the iv pump to run the bolus? (enter a whole number, round as needed. )

Answers

The nurse needs to set the IV pump to provide 4 grams of magnesium sulfate over a 20-minute period to run the bolus.

Since the bolus comes diluted in 250 mL of normal saline, the nurse needs to calculate the rate at which the bolus will be delivered. To do this, the nurse needs to divide the amount of magnesium sulfate (4 grams) by the time it should take to deliver the bolus (20 minutes). This gives a rate of 0.2 grams per minute.

However, since IV pumps deliver in milliliters per hour, the nurse needs to convert this rate to mL/hr. To do this, the nurse multiplies 0.2 grams/minute by 60 minutes/hour, giving a rate of 12 mL/hour. Therefore, the nurse should set the IV pump to 12 mL/hour to provide the 4-gram magnesium sulfate bolus over 20 minutes.

The IV pump rate for a 4 gram bolus of magnesium sulfate to run over 20 minutes with a total volume of 250 mL should be set at 750 mL/hr.

To calculate the IV pump rate for a magnesium sulfate bolus of 4 grams to be administered over 20 minutes, we need to know the total volume of the IV fluid which is 250 mL.

Since the entire 250 mL should be administered in 20 minutes, we first convert minutes to hours because infusion pumps are calibrated in mL per hour. Thus, 20 minutes is ⅓ of an hour.

To find the infusion rate in mL/hour, we use the formula:

  • Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
  • Infusion rate = 250 mL / (⅓ hr)
  • Infusion rate = 250 mL / 0.333hr
  • Infusion rate = 750 mL/hr

Therefore, the nurse should set the IV pump to run at a rate of 750 mL/hr to administer a 4 gram bolus of magnesium sulfate diluted in 250 mL of normal saline over 20 minutes.
